Sure - 

This is how I am wiring up the three events  in the Page Load method

this.BillingSheetGrid.ClickCellButton +=new ClickCellButtonEventHandler(BillingSheetGrid_ClickCellButton);
this.BillingSheetGrid.Click +=new ClickEventHandler(BillingSheetGrid_Click);
this.BillingSheetGrid.DblClick +=new ClickEventHandler(BillingSheetGrid_DblClick);

These are the two error messages:

No overload for 'BillingSheetGrid_Click' matches delegate 'Infragistics.WebUI.UltraWebGrid.ClickEventHandler' C:\Development\PFM Contracter AP\CAPS Project\CAPSProject\BillingSheet.aspx.cs 25 43 CAPSProject

No overload for 'BillingSheetGrid_DblClick' matches delegate 'Infragistics.WebUI.UltraWebGrid.ClickEventHandler' C:\Development\PFM Contracter AP\CAPS Project\CAPSProject\BillingSheet.aspx.cs 26 46 CAPSProject

There is no error message for the CellButtonClick even though the structures look identical to me.

Thanks for the help,

Lynn

Any change someone could show this code using VB.Net?

Thanks!

Thanks for asking the question. 

It turns out that I should have had ClickEvents instead of CellEvents.

Everything works now.

This is very weird, I have just tried the following in my projects:

 protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);

        UltraWebGrid1.Click += new Infragistics.WebUI.UltraWebGrid.ClickEventHandler(UltraWebGrid1_Click);
        UltraWebGrid1.DblClick += new Infragistics.WebUI.UltraWebGrid.ClickEventHandler(UltraWebGrid1_DblClick);
        UltraWebGrid1.ClickCellButton += new Infragistics.WebUI.UltraWebGrid.ClickCellButtonEventHandler(UltraWebGrid1_ClickCellButton);

    }

    void UltraWebGrid1_DblClick(object sender, Infragistics.WebUI.UltraWebGrid.ClickEventArgs e)
    {
        throw new NotImplementedException();
    }

    void UltraWebGrid1_ClickCellButton(object sender, Infragistics.WebUI.UltraWebGrid.CellEventArgs e)
    {
        throw new NotImplementedException();
    }

    void UltraWebGrid1_Click(object sender, Infragistics.WebUI.UltraWebGrid.ClickEventArgs e)
    {
        throw new NotImplementedException();
    }

and it worked without any issues - the project was able to compile successfully. Can you please check if the event handlers signature is that same to what I have? You can also try to generate event handlers automatically in code if you press Tab twice after writing "+=" for events - this will generate the correct signature automatically.
