How to pass parameter to OnClientClick function?

[Matthew]

How can I pass the number to the confirm popup message like

===============================

    Confirm to Delete Record ___(No)___?  

===============================

 

CODE in .aspx

<script>

function DeleteConfirm(sender, args) {
            args.set_cancel(!confirm('Confirm to Delete?'));
     } 

</script>

 

<telerik:RadButton ID="btnDelete" runat="server" Skin="Windows7" Text="Delete" CommandName="Delete"
         CommandArgument='<%# Eval("CueId") + "|" + Eval("RevID") + "|" + Eval("No") %>' OnClientClicking="DeleteConfirm"                               visible='<%# If(Eval("AdminPage").ToString() = "Yes", true, false) %>'  
         Enabled='<%# If(Eval("ControlStatus").ToString() = "R", true, false) %>' >
</telerik:RadButton>

Hi Matthew,

To display the specific number ("No") from your data in the confirm popup message, you can extract it from the CommandArgument property of the RadButton in your JavaScript function. The sender parameter in the OnClientClicking event refers to the client-side RadButton object, and you can use its get_commandArgument() method to retrieve the value.

Here’s how to update your function:

function DeleteConfirm(sender, args) {
    var commandArgument = sender.get_commandArgument(); // "CueId|RevID|No"
    var parts = commandArgument.split('|');
    var recordNo = parts[2]; // "No" value

    var message = 'Confirm to Delete Record ' + recordNo + '?';
    if (!confirm(message)) {
        args.set_cancel(true);
    }
}

How this works:

• sender.get_commandArgument() gets the string you set in the CommandArgument property.
• .split('|') separates the values, so you can access the third value (parts[2]) which is your "No".
• The confirm dialog will show the message with the specific record number each time the button is clicked.

This approach will dynamically display the number in your confirm popup as you need.
