                sb.Append(@"{");
                sb.Append(@"alert('before failure');");
                hdnfld.value="0";
                sb.Append(hdnfld);
                sb.Append(@"}");
                sb.Append(@"</script>");
}

What I have tried:

Public void GetData(){                
HtmlInputHidden hdnfld = new HtmlInputHidden();
                StringBuilder sb = new StringBuilder();
                sb.Append(@"<script type='text/javascript'>");
                sb.Append(@"var r = confirm('do you want to Checked-Out?');");
                sb.Append(@"if(r == true)");
                sb.Append(@"{");               
                hdnfld.value="1";
                sb.Append(hdnfld);
                sb.Append(@"}");
                //For cancel
                sb.Append(@"else");
                sb.Append(@"{");
                sb.Append(@"alert('before failure');");
                hdnfld.value="0";
                sb.Append(hdnfld);
                sb.Append(@"}");
                sb.Append(@"</script>");
}

Solution 2

why you using this : sb.Append(hdnfld);
if you want value than use : sb.Append(hdnfld.value);
if you want to accept hidden field value from Javascript than use : sb.Append("document.getElementById('hdnfld')
.value");

           StringBuilder sb = new StringBuilder();

Hi karthik, Thank you once again, after click 'ok' need to pass hidden field value to .cs file these everything should happen in form load only, is it possible?. if it is. could you send me the code.

Karthik_Mahalingam 28-Apr-16 3:19am

you will have to define the hidden field on the aspx file. so that you can access the hidden field control easily..

<asp:HiddenField runat="server" ID="hdnfld" />

Member 12477201 28-Apr-16 3:21am

Am explaining scenario. need to show confirmation box, if user clicks yes/ok then access x(), no/cancel then acess y() from code behind in pageload() only.

Karthik_Mahalingam 28-Apr-16 3:24am

when to show the confirm box?
accessx() ? what is that js method or cs method?
could you please explain, i need more info

Member 12477201 28-Apr-16 3:26am

page load only show the confirm box. after click ok in that box acess x(), these thing should happen in .cs file only.

Karthik_Mahalingam 28-Apr-16 3:32am

x() is a cs method?

Karthik_Mahalingam 28-Apr-16 3:40am

try this

Create a dummy asp:button in the aspx file and create a button click event
in the button click event check the hidden field value and based on the value, call the required function

Member 12477201 28-Apr-16 4:44am

we need confirmation Box 'ok' click only need to call x() method in code behind

Karthik_Mahalingam 28-Apr-16 5:06am

:(you are not understanding my point.

Karthik_Mahalingam 28-Apr-16 5:14am

use this code.

StringBuilder sb = new StringBuilder();
sb.Append(@"<script type='text/javascript'>");
sb.Append(@"var r = confirm('do you want to Checked-Out?');");
sb.Append(@"if(r == true)");
sb.Append(@"{");
sb.Append(@"document.getElementById('hdnfld').value='1';");
sb.Append(@"document.getElementById('btnDummy').click();");
sb.Append(@"}");
//For cancel
sb.Append(@"else");
sb.Append(@"{");
sb.Append(@"alert('before failure');");
sb.Append(@"document.getElementById('hdnfld').value='0'");
sb.Append(@"document.getElementById('btnDummy').click();");
sb.Append(@"}");
sb.Append(@"</script>");

------------------------------------------------------

protected void btnDummy_Click(object sender, EventArgs e)
{
if (hdnfld.Value == "1")
X();
else
Y();
}

private void X()
{ }
private void Y()
{ }

-----------------------------------------

<asp:HiddenField runat="server" ID="hdnfld" />
<asp:Button Text="." ID="btnDummy" style="display:block" runat="server" OnClick="btnDummy_Click" />

Member 12477201 28-Apr-16 5:10am

Karthik_Mahalingam 28-Apr-16 5:15am

check the above code

Member 12477201 28-Apr-16 5:28am

Hi karthik, everything should be in code behind only. we don't have aspx page. Thanking you for help.

Member 12477201 28-Apr-16 5:35am

And your placed one hiddenfield and button in aspx. all should happen in page load only.

Karthik_Mahalingam 28-Apr-16 5:50am

is that asp.net or ?

Member 12477201 28-Apr-16 5:52am

this one is share point customization in infopaths?.

Karthik_Mahalingam 28-Apr-16 6:00am

oh. ok.

Member 12477201 28-Apr-16 6:18am

But we write code in code behind, so is it possible?.

Karthik_Mahalingam 28-Apr-16 6:28am

i have not idea on infopath, if so i would have helped you.

Um.
Look at what your code is doing!
There are a number of obvious problems here: the first is that GetData doesn't do anything. You append lots of items to a StringBuilder, but as it's local to the method it's all thrown away when the method exits - so effectively your method does nothing at all!
Second, hdnfld is also local to the method, so setting it's value to anything doesn't do anything useful either, as it is also discarded when the method ends.
Thirdly, even if you send the StringBuilder content to your website at the end of the method, it's not going to do anything useful, because the hidden field you set will not be part of the page!
So have a look at the documentation: HtmlInputHidden Class (System.Web.UI.HtmlControls)[^] and see what their example does!
