This control is for login form and i just cant get the values from input boxes because event don't trigger. One idea was to make AJAX post to static method but after that i cant make new session with this variables.
I try everything and this button just doesn't fire the event. I don't know what to do next, can you help me.
Ok after one more day of struggle, i manage to make a little walk around path:
In the first step i made a Button to fire event (javascript function) and make cookie, after that i make click event for actual asp:Button :
<script type="text/javascript">
function LoginClicked() {
var inputEmail = $("#txtEmail").val();
var inputPass = $("#txtPassword").val();
if(inputEmail != "" && inputPass != ""){
var userSet = inputEmail + "&" + inputPass;
setCookie("UserSettings", userSet, 1);
function setCookie(cname, cvalue, exdays) {
var d = new Date();
d.setTime(d.getTime() + (exdays*1*60*1000));
var expires = "expires=" + d.toGMTString();
document.cookie = cname+"="+cvalue+"; "+expires;
}
$("#ctl00_UserLogin_btnLogon").click();
}
}
</script>
And here is the buttons:
<asp:Panel runat="server" ID="panekl">
<asp:Button runat="server" ID="btnLogon" UseSubmitBehavior="false" CssClass="no-display" ></asp:Button>
</asp:Panel>
<button class="login-btn" id="btnLogon1" name="btnLogon1" onclick="LoginClicked()">
<i class="fa fa-paper-plane"></i><MultiLanguage:MultiLanguageLiteral ID="MultiLanguageLiteral4" runat="server" Resource="1270" />
And in the back end, i get the cookie, split it, and check for validation:
public void btnLogon_Click()
{
if (LoginSet == false )
{
string[] txtSome = Request.Cookies["UserSettings"].Value.Split('&');
if (Request.Cookies["UserSettings"] != null && txtEmailVal != "" && txtPassword != "")
{
txtEmailVal = txtSome[0].Trim();
txtPassword = txtSome[1].Trim();
}
String[] RemoteAddr = Request.ServerVariables.GetValues("REMOTE_ADDR");
if (RemoteAddr.Length <= 0)
return;
LoginDB oLoginDb = new LoginDB(txtEmailVal, txtPassword, true, RemoteAddr[0].ToString());
oLoginDb.Database = new SQLDatabase(Convert.ToString(ConfigurationManager.ConnectionStrings["dbConnectionString"].ToString()));
try
{
if (oLoginDb.Authenticate(ConfigurationManager.AppSettings["SecKeyIni"].ToString(), ConfigurationManager.AppSettings["SecKeySec"].ToString()))
{
Session["IdUserLogin"] = txtEmailVal;
_loginSet = true;
HttpCookie myCookie = new HttpCookie("UserSettings");
myCookie.Expires = DateTime.Now.AddDays(-1d);
Response.Cookies.Add(myCookie);
Label1.Text = "submit button is press";
}
else
{
_loginSet = false;
}
}
catch (Exception Exception)
{
Context.Trace.Warn(Exception.Message);
Global.ErrorMessage(Exception.Message, Context);
_loginSet = false;
}
}
}
This was the only way i figured out to get values from the control.

I am creating a quiz application in ASP.net (c#) and I currently have one question at a time displaying with the use of a datapager. However, when i move from question 1 to question 2 and then back to question 1 the radiobutton selection disappears.
EDIT - I now have the radio button retaining a selection whenever I move from next to previous, HOWEVER, If I chose radiobutton1 and then move on to question 2, It has radiobutton1 already selected, even though I am yet to answer that question. So for some reason whatever selection I make on question 1 is being duplicated to the other questions.

Try overriding LoadViewState and SaveViewState to maintain the state of your radio buttons. For example, try something like the following, and pull the values back out of ViewState wherever you need them:
protected override void LoadViewState(object savedState)
{
base.LoadViewState(savedState);
if (ViewState["Radio1"] != null)
Radio1.Text = (int)ViewState["Radio1"];
...
}
protected override object SaveViewState()
{
ViewState["Radio1"] = Radio1.Text;
...
return base.SaveViewState();
}

I am using asyncupload control of AjaxControlToolkit and I want to check the file to be uploding is already exists or
not on server.
How we can do this?
Please help me out.
<!-- Client side code for control-->

//document.getElementById('lblStatus').innerText = args.get_fileName(), "<span style='color:red;'>" + args.get_errorMessage() + "</span>";
}
function StartUpload(sender, args) {
var nodeSelectedText = document.getElementById('<%=lblFileLocation1.ClientID%>').innerHTML;
if (nodeSelectedText == "") {
$("#msgMissingSelection").dialog("open");
args.set_cancel(true);
}
else {
return true;
}
}
function UploadComplete(sender, args) {

if(hdnFieldVal.value == "1")
{

}
}
Thanks!!
you just need to set your hidden field value at client side script.
See I have made little changes in your server side code:
protected void AsyncFileUpload1_UploadedComplete(object sender, AjaxControlToolkit.AsyncFileUploadEventArgs e)
{
string filePath = "C:\\Documents\\temp.txt";
string hiddenValue = "0";
if (File.Exists(filePath))
{
hiddenValue = "1";
}
//This script will set required value for hidden field.
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "SetHiddenField", String.Format("top.$get('{0}').value = '{1}'", hdnField.ClientID, hiddenValue), true);
}
Make changes in your script location as follow:
<ajaxToolkit:ToolkitScriptManager runat="Server" EnablePartialRendering="true" ID="ScriptManager1" />
<script>
function uploadError(sender, args) {
//document.getElementById('lblStatus').innerText = args.get_fileName(), "<span style='color:red;'>" + args.get_errorMessage() + "</span>";
}
function StartUpload(sender, args) {
var nodeSelectedText = document.getElementById('<%=lblFileLocation1.ClientID%>').innerHTML;
if (nodeSelectedText == "") {
$("#msgMissingSelection").dialog("open");
args.set_cancel(true);
}
else {
return true;
}
}
function UploadComplete(sender, args) {
var hdnFieldVal = document.getElementById('<%=hdnField.ClientID%>');
if(hdnFieldVal.value == "1")
{
$("#msgFileUploadExists").dialog("open");
}
else
{
$("#msgFileUpload").dialog("open");
}
}
</script>
Check if the file exists using the following:-
File.Exists
You can compare based on the filename.

There is problem related to update panel.
Use below code:
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnAdd" EventName="Click" />
<asp:PostBackTrigger ControlID="btnSubmit" />
</Triggers>
So submit button cilck event will fire.
Thanks
First You have to remove Nested For Loop
String lstName;
for (int i= 0; i< listBoxEmployeeName.Items.Count;i++)
{
lstName=listBoxEmployeeName.Items[i].Text;//Here your value stored in lstName
//here continue you insert query
}
I have a GridView in Which I have four TextBoxes in the Template Field. I have one Button below the GridView.
How to validate the TextBoxes in the GridView, When the Button Clicked?
use RequiredFieldValidator and set ValidationGroup="gridview", check below example
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:TextBox ID="TextBox3" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfv" runat="server" ControlToValidate="TextBox3" ValidationGroup="gridview" ErrorMessage="RequiredFieldValidator"></asp:RequiredFieldValidator>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="">
<ItemTemplate>
<asp:Button ID="Button2" runat="server" Text="Button" ValidationGroup="gridview" CausesValidation="true" />
</ItemTemplate>
</asp:TemplateField>
You can use the JQuery Validation Plugin
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script type="text/javascript" src="http://dev.jquery.com/view/trunk/plugins/validate /lib/jquery.delegate.js"></script>
<script type="text/javascript" src="http://dev.jquery.com/view/trunk/plugins/validate/jquery.validate.js"></script>
<script type="text/javascript">
jQuery.validator.setDefaults({
debug: true,
success: "valid"
});;
</script>
<script>
$(document).ready(function(){
$("#myform").validate({
rules: {
field: "required"
}
});
});
<body>
<form id="myform">
<label for="field">Required: </label>
<input class="left" id="field" name="field" />
<br/>
<input type="submit" value="Validate!" />
</form>
</body>
<script type="text/javascript">
function ValidateGridview() {
titlename = document.getElementById('<%=((TextBox)grd_party_influenc.FooterRow.FindControl("txt_f_title")).ClientID%>');
if (titlename.value ==0) {
alert("Please Insert The Title ....");
titlename.focus();
return false;
}
// return true;
}
</script>
And then call the JavaScript function through link button like this:
<asp:LinkButton ID="lnk_btn_insert" runat="server" CommandName="Insert" OnClientClick="ValidateGridview()">Insert</asp:LinkButton>
i have 7 textbox
ok i have worked on my JS function and it worked for me.hope it will
work for everyone else.in my code i have taken a variable
success which is working as a flag and i am checking it twice and
returning true at the end so that if one of the textbox is not empty
and other not it will not return true.
sorry for poor editing
function fnCheck(val) {
var success = true;
var v = val.id.split('_')[1];
var merter = document.getElementById('GridSubMeter_' + v + '_txtMeterIdn').value.trim();
var Billper = document.getElementById('GridSubMeter_' + v + '_txBillPer').value.trim()
var Endkwh = document.getElementById('GridSubMeter_' + v + '_txEndKwh').value.trim();
var startkwh = document.getElementById('GridSubMeter_' + v + '_txStartKwh').value.trim();
var ReadEndDate = document.getElementById('GridSubMeter_' + v + '_txReadEndDate').value.trim();
var ReadStartDate = document.getElementById('GridSubMeter_' + v + '_txReadStartDate').value.trim();
var CTFACT = document.getElementById('GridSubMeter_' + v + '_txCTFact').value.trim();
debugger;
if (merter != '') {
}
else {
alert("Meter Identifier is Required Field");
success = false;
}
if (Billper != '') {
}
else {
alert("Bill Period is Required Field");
success = false;
}
if (Endkwh != '') {
}
else {
alert("EndKwh is Required Field");
success = false;
}
if (startkwh != '') {
}
else {
alert("StartKwh is Required Field");
success = false;
}
if (ReadEndDate != '') {
}
else {
alert("Read EndDate is Required Field");
success = false;
}
if (ReadStartDate != '') {
}
else {
alert("Read StartDate is Required Field");
success = false;
}
if (CTFACT != '') {
}
else
{ alert("CT Factor is Required Field");
success = false;
}
return success;
}
onclientclick
<asp:Button ID="btn_Update" Style="background-color: #B2DE94; width: 40px" CausesValidation="false" runat="server" OnClientClick="return fnCheck(this);" Text="Update" CommandName="Update" />
