How to add a "confirm delete" option in ASP.Net Gridview?

Ok lets say you do have a grid with a button inside template column

<asp:Button ID="btnSave" runat="server" Text="Save" OnClientClick="return check();" />

and write in your check function determine if button should raise a postback?

<script type="text/javascript">

function check() {

  var doINeedToAskUserConfirmation =  // Get this according to your needs
  if ( doINeedToAskUserConfirmation  ){
      return confirm("Are you sure?");
  }
  return true;
}

</script>

lets say you have a button

<input type="button" id="btnConfirm" value="Proceed"/>

Make an ajax call to determine if you need any confirmation. 

$("#btnConfirm").click(function(){

   $.ajax({
     type: "POST",
     url: "some.ashx",
     data: { name: "John", location: "Boston" }
  }).done(function( response ) {
     // lets say when response is true we will ask confirmation
     if ( msg )
     {
        var c = confirm( "All record will be deleted. Are you sure ? ");
        // Do another ajax call to complete your operation
     }
  });


});

Depending on what kind of you events you are using, you could create a class that derives from EventArgs and place your condition as a property (and call it MyCondition for instance) in your own class.

In the eventhandling method, you can then use 

if(e.MyCondition)
{
  // do something
}

Edit: Based on you comments, I'd suggest you try to use a DetailsView for Editing, or use the GridViews Editmode if you like.
You may also take a look at the CustomValidator.

  • hum, it look way too hard for what I'm doing, I want to ask for a save confirmation, is there a easier way to do it ? – GmodCake Jan 09 '13 at 17:02
  • Hmm you said server-side. Save confirmation indicates client-side interaction. – citronas Jan 09 '13 at 17:04
  • I can work on both, I just need to get the response of the confirmation on the server-side ... – GmodCake Jan 09 '13 at 17:06
  • Are you talking about a control, like a checkbox and server-side validation that validates if the checkbox is actually checked? – citronas Jan 09 '13 at 17:10
  • I'm working with a aspxgridview, when the user select a row, the content of the row is loaded in some textbox, when he modify one of them, a boolean named EditorMode change to "true" and if it is true, when somethings else happen, a confirmation message shows up, and I want to get the answer given from this confirmation message on the server-side – GmodCake Jan 09 '13 at 17:15
  • Sorry for my horrible english, i'm a french canadian – GmodCake Jan 09 '13 at 17:19
  • I'm still not understanding what you call a confirmation message. A confirmation message sound like a read-only text for me, that you are creating on the server side. I'll post you two links to the MSDN, that I think could help – citronas Jan 09 '13 at 17:21
  • I'm talking of a pop-up that says "Are you sure you want to ... ?" and I want to know if he answered "Yes" or "No" – GmodCake Jan 09 '13 at 17:24
