Javascript confirmation message issue

Question

I have a confirmation popup that I can show as below.

But I do not know if the user clicked ok or canceled.

                ScriptManager.RegisterStartupScript(this, this.GetType(), "ajax", "<script language='javascript'>confirm('Do u wanna change?');</script>", false);

so what I want to do like this.

if (orignalId != newId)
                {
 ScriptManager.RegisterStartupScript(this, this.GetType(), "ajax", "<script language='javascript'>confirm('Do u wanna change?');</script>", false);

If (user clicks Yes)
{
add some data to SQL
}
else
{
return;
}
}

How to find out what the user clicked?

I tried this

• I put the code below in the folder1 \ jscrip.js file, but I don’t know what to name it, because I have the ajax update panel used on the page, so I can not use ClientScript.RegisterClientScriptInclude to link to it. as indicated in paragraph 6 by this link: http://www.dotnetcurry.com/ShowArticle.aspx?ID=274

Page.ClientScript.RegisterClientScriptInclude ("selective", ResolveUrl (@ "folder1 \ jscrip.js"));

function confirmation()
{
if(confirm("Are you sure?")==true)
return true;
else
return false;
}

Any suggestions??? thank

    var x = confirm("Are you sure you want to Delete?");
    if (x)
    { 
        document.getElementById('Hidden1').value = "True";
    }
    else
    {
        document.getElementById('Hidden1').value = "False";

, , , , - , . javascript , ( , ..) , ​​ db, , , OnClientClick asp: button asp: linkbutton :

<asp:LinkButton Text="Delete" ID="DeleteProj" runat="server" CommandName="deleteproj" OnClientClick="return confirm('Are you sure?');" CommandArgument='<%# Eval("ProjectID") %>'/> 

By clicking the "No" button, you will send the user back to your page by clicking "yes", any C # code that you set for him will be launched. It worked for me.

ScriptManager.RegisterStartupScript often tends to block a popup. If you try the approach in the link below, you will have full control over each click of the mouse in the pop-up window.

This popup does not need ajax, javascript, jquery or css trick, but gives you full control.
