Answer 1

One of the workaround can be to store the TRUE / FALSE flag in control that has the attribute runat="server", depending on the choice made by user (Yes / No). And then at the backend, you can check for the value of this control.

Answer 2

Use AJAX toolkit with modalpopupextender.

   <cc1:modalpopupextender id="ModalPopupExtender1" runat="server"  cancelcontrolid="ButtonNo" okcontrolid="ButtonYes" popupcontrolid="PNL" targetcontrolid="UrSaveButton">
   </cc1:modalpopupextender>  
   <asp:Panel ID="PNL" runat="server" Style="display: none; width: 200px; background-color: #000099; border-width: 2px; border-color: Black; border-style: solid; padding: 20px;">
     <span style="color: White; font-weight: bold">Record already exist.Do you want to proceed?</span>
       <br />
        <br />
            <div style="text-align: right;">
                <asp:Button CssClass="tbl_blue" ID="ButtonYes" runat="server" CausesValidation="false" EnableTheming="false" Text="YES" />
                <asp:Button CssClass="tbl_blue" ID="ButtonNo" runat="server" CausesValidation="false" EnableTheming="false" Text="NO" />
             </div>
  </asp:Panel>

You can Customize it as you want.

Answer 3

You can do this in many ways:

One is place a button on the page, make its display:none and when confirm is true, trigger its click with js.

Like in aspx

<asp:Button runat="server" ID="btnSaveData" 
     onClick="btnSaveData_Click" style="display:none;" />

in client side make a js function for calling confirmation dialog box, like

function ConfirmSave()
{
   if(confirm('Record already exist.Do you want to proceed?')
   {
       jQuery("[ID$=btnSaveData]").click();
   }

}

in Code Behind

Your code check in some event handler

if (check == true)
{            
    ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "script", 
      "ConfirmSave();", true);
}

bthSaveData click handler for saving data.

protected void btnSaveData_Click(object sender, EventArgs e)
{
 // Code for your saving.
}

Answer 4

you can take a look at the this link http://www.codeproject.com/Articles/8173/A-Simple-ASP-NET-Server-Control-Message-Box-Confir.

And more over you can create your own custom confirmation box.

Answer 5

You can use confirm box in JS like this

var ans = confirm ('Record already exist.Do you want to proceed?');
if(ans==true)
{
}
else
{
}

Secondly, to get the response in code behind, you can store the Yes/No value into a hidden field e.g.

document.getElementById('<%= hiddenField.ClientID %>').value = ans;
