The textbox doesn't get any value when I debug the program.
I have tested the stored procedure in SQL Server and it works fine. But the data returned from the SQL code is empty.
My button submit code:
namespace PetShop.User
{
public partial class Consulation : System.Web.UI.Page
{
SqlConnection con;
SqlCommand cmd;
protected void Page_Load(object sender, EventArgs e)
{
}
private void clear()
{
txtEmail.Text = string.Empty;
txtDescription.Text = string.Empty;
txtNameAcc.Text = string.Empty;
txtSDT.Text = string.Empty;
txtNgay.Text = string.Empty;
txtTime.Text = string.Empty;
ddlCategory.ClearSelection();
}
protected void Add_Click(object sender, EventArgs e)
{
string actionName = string.Empty;
bool isValidToExcute = true;
con = new SqlConnection(Connection.GetConnectionString());
cmd = new SqlCommand("Add_KHaddLH", con);
cmd.Parameters.AddWithValue("#Action", "INSERT4KH");
cmd.Parameters.AddWithValue("#MaDv", ddlCategory.SelectedValue);
cmd.Parameters.AddWithValue("#EMail", txtEmail.Text.Trim());
cmd.Parameters.AddWithValue("#Ten", txtNameAcc.Text.Trim());
cmd.Parameters.AddWithValue("#Sdt", txtSDT.Text.Trim());
cmd.Parameters.AddWithValue("#NgayHen", txtNgay.Text.ToString());
cmd.Parameters.AddWithValue("#GioHen", txtTime.Text.Trim());
cmd.Parameters.AddWithValue("#GhiC", txtDescription.Text.Trim());
if (isValidToExcute)
{
cmd.CommandType = CommandType.StoredProcedure;
try
{
con.Open();
cmd.ExecuteNonQuery();
actionName = "gửi";
lblMsg.Visible = true;
lblMsg.Text = "Lịch hẹn " + actionName + " thành công!";
lblMsg.CssClass = "alert alert-success";
clear();
}
catch (Exception ex)
{
lblMsg.Visible = true;
lblMsg.Text = "Lỗi !!!" + ex.Message;
lblMsg.CssClass = "alert alert-danger";
}
finally
{
con.Close();
}
}
}
}
}
I think the error lies in the page reload, because when submitting it will delete all the data in the textbox and then enter.
I've tried adding some commands to the button but still can't handle that it keeps losing textbox data.
I update code behind and markup.
Support me,
Thank.

Ok, so that helps a boatload.
if we have this code:
protected void Add_Click(object sender, EventArgs e)
{
string actionName = string.Empty;
bool isValidToExcute = true;
Debug.Print(txtEmail.Text);
output:
So, you might want to put a break point in, or simple add some debug.prints, and see which text box controls are "empty". But, just looking at what you have, those text boxes should be ok.
And including page-load, shows that you not say running the "clear" routine you have. (so, having included the page load event eliminates about 100 possible issues here. This is VERY much why posting some of your code allows the public here to eliminate a 100 "back and forth" suggestions.) So, for example, had you included "clear" routine in page load, then of course page load fires each and every time BEFORE a button click event, so code in page load is VERY OFTEN suspect here. But, since you don't have code in page load event, we scratch that off the table.
So, far, the controls look to have values, but I suggest you add a break point, or some debug.prints as per above to be 100% sure that the controls in fact do not have values.
Also, just pasting in some of the markup, we see things like this:
So, you do have stray "garbage" in a number of places. (not good).
As it stands, with the posted markup, I MOST certainly do get/see/have/enjoy/observe that the text boxes are intact, do have values.
Given we can't re-produce your issue?
I suggest creating a blank new page, drop in some of those controls, and try a test button - (don't even bother with the database save code - we NOT gone that far down the debugging road just yet).
So, only thing so far?
Are you 100% sure the text boxes don't have values, and you tested this BEFORE any of the database save code runs?
and do remove the stray "required" markup in that txtEmail box, the editor even HONKS OUT AT YOU that the markup is bad as per above screen shot.
In fact, drop in another button on the form, and its only job would be to debug print out the text boxes - does that work?
As it stands now, you don't have a re-producable error, and the community in general here has not, does not see your error, nor are we the viewing public EVEN able to re-produce that these text boxes don't have values.
As a result, there information we don't have to re-produce the error.
I suggest building a page with just the txtEmail that is blank, and a simple button. if that works, then start adding markup from that other page until it stops working, since we here can't re-produce your issue with the provided code and markup you have provided.
And, since you using a master page, then check if page load in master page has any code that runs on page load.

Dynamically list data in dynamic repeater (Asp.Net)

In my project, i've been trying something for a while. User must select the Group from select. This Add button runs asp repeater so i can list groups. There are 2 button in group line. Right one delets the group and left one opens dynamic divs. (As you can see) There are some Javascript works so i set the id's dynamically. It's ok until here. Now, if the user want to check fixed questions, i need to show the questions that in that group. And user must be able to add question under the group dynamically. I tryed to use GridView but i couldnt handle. So any advice?
Here is what i want to do:
<ul>
<asp:Repeater ID="GroupRepeater" runat="server">
<ItemTemplate>
<li class="groupli">
<div style="width:100%; float:left; margin-top:2%;">
<h3 style="display:block; float:left; width:auto;"><%# Container.ItemIndex+1 %>.<%# Eval("QuestGroup")%></h3>
<asp:Button CssClass="GroupLiButtonD" OnClick="RemoveGroup" CommandArgument='<%# Eval("QuestGroup") %>' ID="DeleteGroupBtn" runat="server"/>
<button type="button" onclick="ShowQuestArea('<%# Container.ItemIndex+1 %>_div')" class="GroupLiButtonA"></button>
</div>
<div id='<%# Container.ItemIndex+1 %>_div' style="width:100%; margin-left:3%; float:left; display:none;">
<div class="questarea">
<div style="width:100%; margin-top:1%;">
<h4 style="display:block; float:left; width:200px;">Add Fixed Question</h4>
<input name='check_<%# Container.ItemIndex+1 %>' id='fixcheck_<%# Container.ItemIndex+1 %>' onchange="FixedCheck('fixcheck_<%# Container.ItemIndex+1 %>','<%# Container.ItemIndex+1 %>')" type="radio" />
</div>
<div id="fixarea_<%# Container.ItemIndex+1 %>" class="subarea"> <%--fixedquestion view start tag--%>
</div> <%--fixedquestion view end tag--%>
<div style="width:100%; margin-top:1%;">
<h4 style="display:block; float:left; width:200px;">Add Random Question</h4>
<input name='check_<%# Container.ItemIndex+1 %>' id='randomcheck_<%# Container.ItemIndex+1 %>' onchange="RandomCheck('randomcheck_<%# Container.ItemIndex+1 %>','<%# Container.ItemIndex+1 %>')" type="radio" />
<div id="randomarea_<%# Container.ItemIndex+1 %>" class="subarea">
<div style="margin-top:1%;">
<p style="color:black; float:left;">Number of Random Questions:</p><input type="number" max="20" min="0" style="width:20px; float:left;" />
<button>Add</button>
</div>
</div>
</div>
</div>
</div>
</li>
</ItemTemplate>
</asp:Repeater>
</ul
My code might seem complicated. I added an image. So you can ignore my code for giving advice. Thank you.

Maybe a bit of jquery and some ajax calls will do the trick.
You can add same class and a data-groupid attribute to the "fixed answer" radio buttons.
Lets say the id of the group questions is resultlist and it is a ul element.
Then you will handle the click to load the questions with ajax
$(".yourclass").on"click", function (e) {
var groupid=$(this).data("groupid");
//get the questions
$.ajax({
type: 'POST',
contentType: "application/json; charset=iso-8859-7",
url: 'yourpage.aspx/yourmethod',
data: "{'group':'" + groupid +"'}",
async: false,
error: function (xhr) {console.log(xhr.responseText);},
success: function (response) {
//Query the jQuery object for the values
var items = response.d;
if (items == null) {
$('#resultlist').empty();
$('#resultlist').append("<li> no questions... </li>");
}
else {
var fragment = "";
$.each(items, function (index, val) {
var theQuestion = val.theQuestion;
var theCode = val.theCode;
fragment += "<li data-qustionid='"+theCode+"' class='question'>"+theQuestion+"</li>";});
$('#resultlist').empty();
$("#resultlist").append(fragment);
}
});
});
in your .cs file you will add a new web method that will get the group's questions
[WebMethod]
public static List<Results> yourmethod(string text, string phone, string type)
{
List<Results> result = new List<Results>();
DataTable question = getQuestions();
if(question!=null){
foreach (DataRow rw in autocomlete.Rows)
{
result.Add(new Results { theQuestion = rw[0].ToString(),
theCode = rw[3].ToString() });
}
}
return result;
}
and likewise you will handle the click of the class question which on click will get the data-questionid and update it to the database. You can add more fields that you need in the data- attributes (link here) Readmore for ajax here

Clear Specific Textboxes ASPX page

I'm having trouble trying to clear these banking and routing numbers that are in a textbox on an aspx page. I've seen it used where they would just specify the ID of the textbox and do a textbox.text = String.Empty(). But that doesn't seem to work here. Maybe I'm using the wrong ID?? I also tried using JQuery .val("") but that didn't seem to work either.
Here's the code, i'd like to clear both Routing and Account text fields on click of a button:
<div id="DivUser1BankInfo" class="labelAndTextboxContainer">
<div class="labelContainer">
<asp:Label CssClass="rightFloat" ID="User1LabelRoutingNumber" runat="server" Text="Routing #:"></asp:Label><br />
</div>
<div class="textboxContainer">
<asp:TextBox ID="User1TextRoutingNumber" CssClass="leftFloat " runat="server" Font-Size="Smaller" Width="180px"
Text='<%# Bind("User1BankRoutingNumber") %>'
Visible='<%# ApexRemington.BLL.VendorBLL.ShowUser1BankInfo((string)Eval("User1BankInfoEditUser")) %>' /><br />
</div>
<div class="labelContainer">
<asp:Label CssClass="rightFloat" ID="User1LabelAccountNumber" runat="server" Text="Account #:"></asp:Label><br />
</div>
<div class="textboxContainer">
<asp:TextBox ID="User1TextAccountNumber" CssClass="leftFloat " runat="server" Font-Size="Smaller" Width="180px"
Text='<%# Bind("User1BankAccountNumber") %>'
Visible='<%# ApexRemington.BLL.VendorBLL.ShowUser1BankInfo((string)Eval("User1BankInfoEditUser")) %>' /><br />
</div>
<button type="button" id="clearButton1">Clear</button>
<div class="button">
<asp:Button ID="User1ClearBankInfo" runat="server" Text="Reset"
Visible='<%# ApexRemington.BLL.VendorBLL.ShowUser1BankInfo((string)Eval("User1BankInfoEditUser")) %>' OnClick="clearFields_btn"/><br />
</div>
The OnClick= "clearFields_btn" code behind =
protected void clearFields_btn(object sender, EventArgs e)
{
}
Thanks for any help!

I haven't worked with ASP.NET in a little while, but I think you may want the OnClientClick event, not OnClick. OnClientClick is for client-side code (your jQuery/JavaScript) and OnClick is for server-side code (your C# or VB.NET).
You'd also want your OnClientClick event method to return false, or the server-side code will also fire.
So I think you want something like:
<asp:Button ID="User1ClearBankInfo" runat="server" Text="Reset"
Visible='<%# ApexRemington.BLL.VendorBLL.ShowUser1BankInfo((string)Eval("User1BankInfoEditUser")) %>
OnClientClick="clearText();"/>
And then clearText would look like this:
<script>
function clearText()
{
//our two IDs
$('input[id*="User1TextRoutingNumber"]').each(function(index) {
$(this).val('');
});
$('input[id*="User1TextAccountNumber"]').each(function(index) {
$(this).val('');
});
return false;
}
</script>
EDIT: shoot, I see my mistake. Fixed the code to clear the text of the textbox, not the button ("this").
Edit: removed the space from the "clear" text val.
EDIT: Made search a little more flexible, less dependent on GridView or no GridView.

Try this
<script>
var clear = function(textboxID){$('input[id*=' + textboxID + ']').val('');};
return false;
</script>
<button id="btClearText" onclick="javascript:return clear('txtName');">
but if you need a more specific answer then please post more information

You need something like this. Assuming you want a client side solution (not very clear from your question).
<script type="text/javascript">
function clearTextBox() {
document.getElementById("<%= User1TextRoutingNumber.ClientID %>").value = "";
//or
$("#<%= User1TextRoutingNumber.ClientID %>").val("");
}
</script>
The <%= User1TextRoutingNumber.ClientID %> will ensure you get the correct ID for javascript/jQuery.
A server side solution would be:
protected void clearFields_btn(object sender, EventArgs e)
{
for (int i = 0; i < GridView1.Rows.Count; i++)
{
TextBox tb = GridView1.Rows[i].FindControl("User1TextAccountNumber") as TextBox;
tb.Text = "";
}
}

Control 'MainContent_forenameTxt' of type 'TextBox' must be placed inside a form tag with runat=server

Control 'MainContent_forenameTxt' of type 'TextBox' must be placed inside a form tag with runat=server. [And similar errors]
This error has been bugging me for a few days now. I've narrowed the problem down to an issue being within my Master Page.
For some reason, ASP TextBoxes, Buttons etc.. require to be in a form (Which shouldn't necessarily be the case) however my Program decided that it wants to be.
So, this issue began when I placed the forms in, stating I could only have one with a runat="server". After much googling and questioning I was given this piece of code:
public override void VerifyRenderingInServerForm(Control Control)
{
//base.VerifyRenderingInServerForm(Control);
}
Which, from what I can see, does absolutely nothing. It never gets called, and has nothing in it, however makes the page display - so I have absolutely no idea what it does.
So continuing on, it began to bug me, then I realised that my Buttons weren't actually doing anything, except 'refreshing' the page essentially. (Refer to near the bottom of page, with the onClicks
<%# Page Title="Registration" Language="C#" AutoEventWireup="true" MasterPageFile="~/MasterPage.Master" CodeFile="registration.aspx.cs" Inherits="registration" %>

{

reposit.addCustomerAccount(registerUsernameTxtbox.Text.ToString(),

addressLn1Txt.Text = "";
addressLn2Txt.Text = "";
postalTxt.Text = "";
registerUsernameTxtbox.Text = "";
registerPasswordTxtbox.Text = "";
passwordConfirmTxt.Text = "";
}
Now from that alone, I never saw any issues (unless someone else can see any).
So now, I assumed that the issue is on the masterpage. I've went through the masterpage, comparing it with an old website I built and couldn't find the issue.

Now just to add on as a side-note.
I'm currently using a BootStrap UI Template for my website. I've took highlights of pieces of code which would/could be causing the problem
Things that I have noticed/tried:
- Buttons on MasterPage work fine.
- Buttons on 'registration' page don't work (i.e reset and submit)
- The parameter on the registration page was too big, so placed all details in that method instead
- MasterPage MainContent - Placing a Form within this.
- Removing all forms
- Create a new testpage which doesn't use MasterPage (buttons do work)
- Compared with my other website
I'm no expert at fixing issues, and have struggled to find this error, which you'll most likely find much more quickly than myself.
I'd like to apologise for such a large issue/question, but I'd like to get this sorted and not repeat my problem again in the future.
Thanks for looking at this.

I never found the issue. However, I found a workaround until I can find a sufficient alternative.
I started a new Project in Visual Studio, and decided to pick out every piece of information which would be an absolute necessity for the Website to still look relatively decent, and work.
[This means, I have one form over a contentplaceholder, which is holding everything, including another contentplaceholder where the information from every other page is in that placeholder].
I am still getting a few of the errors (which are easily fixable), however the override class is now, not being used due to some debugging finds, I found that it was overriding the button onClicks.

Method:
protected void btAddPost_Click(object sender, EventArgs e)
{
AddpostfromFront();
}
private void AddpostfromFront()
{
if (FUFile.PostedFile.ContentLength != 0)
{
string tempVar = "~/res/Posts/" + FUFile.Value.ToString();
FUFile.PostedFile.SaveAs(Server.MapPath(tempVar));
ftier.Addpostfromfront(LoggedUserID, "4", txpost.Value, tempVar, DateTime.Now, DateTime.Now, false, false);
}
}

I think what you need to do instead of check the length of the file is to use a method that is built into PostedFile to check if there is a file to begin with.
if you look on the Microsoft page for PostedFile your code would look more like this
Private void AddpostfromFront() //I don't like your naming on this, should be AddPostFromFront
{
if (FUFile.HasFile)
{
string tempVar = "~/res/Posts/" + FUFile.Value.ToString();
FUFile.SaveAs(tempVar);
}
}
to use these methods you may have to use the ASP control instead of the HTML tag, <asp:FileUpload></asp:FileUpload> you will have to adjust the attributes to fit your situation and naming scheme. This would replace your HTML tag <input type="file" runat="server" class="upload" id="FUFile" />
I think that you are meshing two processes into one and getting confused as to what your code should be doing.
no clue what ftier is and why it has the same method name with the same bad naming scheme, or what it is doing with that information.
you should do this in 3 steps
upload the file
save the file
if you need to display the file then do so with the file that is saved, not the file that is being uploaded.
