ASP.net prevent gridview row click in edit mode

I have some issue with ASP.net Gridview that I hope people here can help me.
Requirements
Gridview whole row to be clickable to open another page
In editing mode, can change table values through edititemtemplate textbox
Problem
Textbox selection causes the entire row click event to fire and prevents user from changing the textbox text. User can edit table value without opening different page.

I suggest in this part of your code, do not add the full line click when you edit the line (I have add one -if- to check for the edit).
switch (e.Row.RowType)
{
case DataControlRowType.Header:
//...
break;
case DataControlRowType.DataRow:
if((e.Row.RowState & DataControlRowState.Edit) != DataControlRowState.Edit)
e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(remarksGV1, "Select$" + e.Row.RowIndex.ToString()));
break;
}

ASP.NET Repeater not binding

I have issues.
One of them is this one.
I'm trying to bind a list of Hyperlinks to a repeater and I think my code looks all good, but my repeater is sadly lacking in anything. It's totally blank (Apart from the header, which is not databound).
I can't see where the problem is, so I'm hoping you guys can point it out to me.
Code:
Markup
<asp:Panel ID="pnlNavMenu" class="navigation" runat="server" Visible="true">
<div class="search-textbox"><div>
<asp:ImageButton ID="btnSearch" class="Search-Icon"
BackColor="White" runat="server" OnClick="btnSearch_Click"
ImageUrl="~/images/Mobile/mobile-search-icon.png" />
<asp:TextBox ID="txtSearch" runat="server" CssClass="Search" onblur="if(this.value == '') { this.value='Enter keyword or product code'; isSet=true; }"
onmouseover="if(this.value == 'Enter keyword or product code') { this.value='';isSet = true; }"
onmouseout="if(this.value == '' && !isSet) { this.value='Enter keyword or product code'; isSet=>false; }"
MaxLength="255" Text="Enter keyword or product code" ontextchanged="btnSearch_Click"/>
<asp:ImageButton ID="btnClear" class="Search-Cancel" BackColor="White" runat="server" OnClick="btnClear_Click" ImageUrl="~/images/Mobile/mobile-search-cancel.png" />
</div>
</div>
<asp:Panel ID="pnlComputers" runat="server" CssClass="nav-item" Visible="true">
<asp:Label id="lblComp" Text="Computers" runat="server" cssclass="Menu-Panel-Header"></asp:Label>
<asp:Repeater ID="rptComputers" runat="server">

</asp:Repeater>
</asp:Panel

</asp:Panel>
C#
protected void Page_Init(object sender, EventArgs e)
{
if (Session["Customer"] is GPCUser)
{
hlLogInOut.Text = "Log Out";
hlLogInOut.NavigateUrl = "log-in.aspx?logout=1";
hlRegDetails.Text = "My Details";
hlRegDetails.NavigateUrl = "/update-details.aspx";
}
else
{
hlLogInOut.Text = "Log in";
hlLogInOut.NavigateUrl = "/log-in.aspx";
hlRegDetails.Text = "Register";
hlRegDetails.NavigateUrl = "/create-account.aspx";
}
BindCategories();
}
private void BindCategories()
{
if (!IsPostBack)
{
try
{
SqlConnection connect = new SqlConnection();
DataTable Data = new DataTable();
connect.ConnectionString = "SERVER = SERVER-SQL01; Trusted_Connection=yes; DATABASE=PCSQL";
connect.Open();
string query = null;
query = "SELECT * from dbo.STOCK_GROUPS WHERE XW_MAINGROUP = '1' ORDER BY XW_WEBCATNAME ASC";
SqlDataAdapter command = new SqlDataAdapter(query, connect);
command.Fill(Data);
connect.Close();
rptComputers.DataSource = Data;
}
catch (SqlException sqlEX)
{
sqlEX.ToString();
}
}
}
protected void rptComputers_ItemDataBound(object sender, System.Web.UI.WebControls.RepeaterItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.Item | e.Item.ItemType == ListItemType.AlternatingItem)
{
HyperLink hlCompCategories = (HyperLink)e.Item.FindControl("hlCompCategories");
DataRowView dr = (DataRowView)e.Item.DataItem;
hlCompCategories.NavigateUrl = Page.ResolveUrl("~/" + "Computers" + "/" + dr["XW_URL"] + "/index.aspx");
if ((!object.ReferenceEquals(dr["xw_webcatname"], System.DBNull.Value)))
{
hlCompCategories.Text = (dr["xw_webcatname"]).ToString();
hlCompCategories.ToolTip = (dr["xw_webcatname"]).ToString();
}
else
{
hlCompCategories.Text = dr["groupname"].ToString();
hlCompCategories.ToolTip = dr["xw_webcatname"].ToString();
}
}
}
I'm pretty sure that the issue is in the ItemDataBound method because the rest of the panel loads fine (search bar and header, etc.) but none of my links are there.

After
rptComputers.DataSource = Data;
add
rptComputers.DataBind();
Otherwise it won't bind.

You might be missing AutoEventWireup=true in Page header in aspx file.
If not than please try to bind the repeater in the Page_Load event instead binding in Page_Init event.

Pass value from a Repeater row to a textbox on button click in asp.net C#

I have the following repeater wrapped in an Update Panel
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="DropDownList1" EventName="SelectedIndexChanged" />
</Triggers>
<ContentTemplate>
<asp:Repeater ID="skillTable" runat="server">
<ItemTemplate>
<table class="table table-hover">
<tr>
<td>
<asp:ImageButton runat="server" AutoPostBack="True" ID="skillButton" OnClick="skillButton_Click" CommandArgument="<%# Eval(DropDownList1.SelectedValue)%>" class="addText btn btn-success" ImageUrl="~/img/addbut.png" /></td>
<td><asp:Label runat="server" id="skillName" Text='<%# DataBinder.Eval(Container.DataItem, DropDownList1.SelectedValue) %>'></asp:Label></td>
</tr>
</table>
</ItemTemplate>
</asp:Repeater>
</ContentTemplate>
</asp:UpdatePanel>
It kicks out the information from my database perfectly, and it has a button right before the text in each row.
The problem that i have is that I need each button on each row to, when clicked, add the specific line of code in that row to a textbox.
foreach (RepeaterItem item in skillTable.Items)
{
string skill = item.DataItem.ToString();
string text = skillList.Text;
if (!string.IsNullOrEmpty(text))
{
if (!text.Contains(skill))
{
text += " | " + skill;
skillList.Text = text;
}
}
else
{
text = skill;
skillList.Text = text;
}
}
UpdatePanel2.Update();
I have also tried this way,
protected void skillTable_ItemDataBound(object sender, RepeaterItemEventArgs e)
{
int d = 0;
if(DropDownList1.SelectedValue == "Business and Finance")
{
d = 1;
}
else if(DropDownList1.SelectedValue == "Computers and Technology")
{
d = 2;
}
else if (DropDownList1.SelectedValue == "Education")
{
d = 3;
}
else if (DropDownList1.SelectedValue == "Customer Service")
{
d = 4;
}
DataRowView drv = (DataRowView)e.Item.DataItem;
string skill = drv[d].ToString();
Session["Table"] = skill;
}
protected void skillButton_Click(object sender, System.Web.UI.ImageClickEventArgs e)
{
string skill = (string)(Session["Table"]);
string text = skillList.Text;
if (!string.IsNullOrEmpty(text))
{
if (!text.Contains(skill))
{
text += " | " + skill;
skillList.Text = text;
}
}
else
{
text = skill;
skillList.Text = text;
}
UpdatePanel2.Update();
}
but neither one of them seems to work correctly. Any advice? I havent really used repeaters before this, so If there is any other tool that would work better, I'm open for suggestions.
Thanks in advance!

So I figured it out. What I was missing was a way for my site to specifically narrow down what i needed. I added the code blow to my click method and got rid of the ItemDataBound method and it worked like a charm.
Button button = (sender as Button);
string commandArgument = button.CommandArgument;
RepeaterItem item = button.NamingContainer as RepeaterItem;
var workText = (Label)item.FindControl("workName1") as Label;
string work = workText.Text;
string text = workDetails1.Text;
if (text == " ")
text = "";
if (text == "")
{
if (!text.Contains(work))
{
text +="\u2022 " + work;
workDetails1.Text = text;
}
}
else if (!string.IsNullOrEmpty(work))
{
if (!text.Contains(work))
{
text += "\n\u2022 " + work;
workDetails1.Text = text;
}
else
{
workDetails1.Text = text;
}
}
UpdatePanel4.Update();
Hope this helps someone!

Access dynamically created text box in a custom template for an ajax tab

I have a TabContainer in my aspx page as follows

}
now am trying to this on a btnclickevent
public void btnSave_Click(object sender, EventArgs e)
{
try
{
Control cntrl = Page.FindControl("TbxQuantity");
}
catch (Exception ex)
{
}
}
it just returns null. Am i doing something wrong? Kindly Help

As i found the answer to the above question posted by myself, I would like to help fellow folks who encounter the same or similar problem.
string strQuantity=((System.Web.UI.WebControls.TextBox)(((AjaxControlToolkit.TabContainer)(BTN.Parent.FindControl("tabcontainer"))).Tabs[0].FindControl("TbxQuantity"))).Text
Thank you "Stackoverflow" for maintaining the site and I also thank the members who help developers like me.

Your issue isn't with the dynamically added controls, but that the FindControl method doesn't propogate and check all the way down the children stack.
I made a quick helper method below that checks the children until it finds the right control. It was a quick build, so it probably can be improved upon, I haven't tried but you could probably extend the control so you don't have to pass in an initial control. I tested it, however for some reason I couldn't get it to work passing in the Page object, I had to pass in the initial panel I used, but it should get the point across.
Control Finder
public static class ControlFinder
{
public static Control Find(Control currentControl, string controlName)
{
if (currentControl.HasControls() == false) { return null; }
else
{
Control ReturnControl = currentControl.FindControl(controlName);
if (ReturnControl != null) { return ReturnControl; }
else
{
foreach (Control ctrl in currentControl.Controls)
{
ReturnControl = Find(ctrl, controlName);
if (ReturnControl != null) { break; }
}
}
return ReturnControl;
}
}
}

Write GridView to .csv file c# asp.net

I am working on developing a website where customers order directly from our website. I had code working until a few days ago when I changed how the GridView was edited. I had previously set the GridView to AutoGenerate Columns, and have changed that since I needed more functionality for the edit feature. Here is how I create the table (created when user clicks a button to add a quick detail with the GridView):
public void CreateTable()
{
try
{
DataTable table = new DataTable();
if (Session["table"] != null)
table = (DataTable)Session["table"];
else
{
table.Columns.Add("Part Number", typeof(string));
table.Columns.Add("Quantity", typeof(Int32));
table.Columns.Add("Ship-To", typeof(string));
table.Columns.Add("Requested Date", typeof(string));
table.Columns.Add("Shipping Method", typeof(string));
}
DataRow row = table.NewRow();
row["Part Number"] = part;
row["Quantity"] = qty;
row["Ship-To"] = shipto;
row["Requested Date"] = reqdate;
row["Shipping Method"] = shipmthd;
table.Rows.Add(row);
Session["table"] = table;
griditems.DataSource = table.DefaultView;
griditems.DataBind();
}
catch
{
//error message
}
}
This displays the Gridview and allows users to edit/delete the items as they choose. Then I have another button that is displayed when the GridView is created that actually writes the .csv file to the server (my computer for the moment until deployment). Here is the code for that:
protected void orderbtn_Click(object sender, EventArgs e)
{
try
{
//ordernum++;
//custordernum = ordernum.ToString("0000000");
if (userlbl.Visible == false && userlbl2.Visible == false)
{
GlobalList.OnlineOrderNum.Add(custordernum, ordernum);
FileStream fs = new FileStream(#"C:\Web_Order\Orders.Bin", FileMode.Create);
BinaryFormatter bf = new BinaryFormatter();
bf.Serialize(fs, GlobalList.OnlineOrderNum);
fs.Close();
fs.Dispose();
///Write CSV File For Order
StringBuilder strBuilder = new StringBuilder();
TextWriter tw = new StreamWriter(#"C:\Web_Order\Order_W" + custordernum.ToString() + ".csv");
foreach (GridViewRow row in griditems.Rows)
{
foreach (TableCell cell in row.Cells)
{
// get cell's text
string cellText = cell.Text;
// add quotes and comma around value and append
strBuilder.Append("\"" + cellText + "\",");
}
strBuilder.Append("\n");
}
// output CSV result
tw.Write(strBuilder.ToString());
tw.Close();
tw.Dispose();
GlobalList.weborder = "W" + custordernum.ToString();
Response.Redirect("~/OrderSubmitted.aspx");
}
else
{
validatelbl.Text = "CANNOT SUBMIT FORM WITH ERRORS. PLEASE CORRECT YOUR ERRORS BEFORE SUBMITTING.";
validatelbl.Visible = true;
userlbl.Text = "Please correct your table with the correct information before submitting your order";
userlbl.Visible = true;
userlbl2.Text = "Are your Part Numbers correct? Are your Quantities in the correct format?";
userlbl2.Visible = true;
}
}
catch
{
//error message
}
}

I don't understand why it was working all this time and now all of the sudden it is not working. It creates the file with the new ordernumber as it should, its just the .csv file is empty (no data at all) Any thoughts?

You can correct your path, and replace TextWriter with StreamWriter
var path = Path.Combine("C:\Web_Order\Order_W",custordernum.ToString(),".csv");
StreamWriter tw = new StreamWriter(#path);
Or use directly var.
var tw = new StreamWriter(#path);
Adjust your code with try catch block in order to treat exception if occurs
try
{
}
catch(Exception ex)
{
Console.Write(ex.Message);
throw ex;
}

Not sure why you're using TextWriter here, and you don't need to redirect. Just write to Response.Write().
protected void btnDownload_Click(object sender, EventArgs e)
{
// No error so write as attachment
Response.ContentType = "text/csv";
Response.AddHeader("content-disposition", "attachment;filename=data.csv");
// Write your output here
Response.Write(...);
Response.End();
}
