YES OR NO MessageBox

Question

How to I display a confirm message box before deleting records? Buttons should be YES or NO only. Not OK or CANCEL. I have this code but it only works for c# winforms...

if (MessageBox.Show("Delete record no. " + numID.Text + "?", "Confirm User Delete", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.Yes)
{
    //codes to delete records
}

you need to add a reference to System.Windows.Forms library and you have to refer it in your program like -> using System.Windows.Forms; Statement. — Sudhakar Tillapudi, Nov 14 '13 at 03:27
I'm getting this error `The type or namespace name 'Windows' does not exist in the namespace 'System' (are you missing an assembly reference?)` — user2971155, Nov 14 '13 at 03:29
You don't want to use a Windows.Forms.MessageBox. Don't be silly. — SQLMason, Nov 14 '13 at 03:30
Depends on the technology you are using, a good recommendation would be to use Javascript's confirm function. Please embed it into your code to let the user decide and then continue to your action. There is a [similar question about it here](http://stackoverflow.com/a/5867618/428813). [Here is some more light](http://www.w3schools.com/js/js_popup.asp). [And a good example in this link](http://www.aspsnippets.com/Articles/ASPNet-Server-Side-Yes-No-Confirmation-Box-using-JavaScript.aspx). Hope it helps, — Ramon Araujo, Nov 14 '13 at 03:28

If you are displaying this client side, then you should use Javascript. A good way to do this is to use the jQuery dialog method. For example:

Markup:

<div id="dialog-confirm">This is the content</div>

Javascript:

 $( "#dialog-confirm" ).dialog({
      resizable: false,
      height:280,
      modal: true,
      buttons: {
        "Yes": function() {
          $( this ).dialog( "close" );
        },
        "No": function() {
          $( this ).dialog( "close" );
        }
      }
 });
