GGC Validation handling

[Francois Buhagiar]

Hi

I would need to show an error provider in a cell , i noticed that the GGC already dose that when for example you enter letters in a numeric field.
My question is how can i show that icon and highlight the cell red when i do my own validation ?
How can i stop it from showing a message box?
Why is the message box showing three times?

Thanks for the any help
Regards
Francois

Hi Francois,

Thank you for your interest in Syncfusion products.

To disable the default error message, you need to set the e.Inner.Cancel as true in TableControlCurrentCellErrorMessage event.

 void gridGroupingControl1_TableControlCurrentCellErrorMessage(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCurrentCellErrorMessageEventArgs e)
 {
   e.Inner.Cancel = true;
 }

To show the error message when you are doing your own validation, you need to handle TableControlCurrentCellValidating event. Please refer the below code for more details.

 void gridGroupingControl1_TableControlCurrentCellValidating(object sender, Syncfusion.Windows.Forms.Grid.Grouping.GridTableControlCancelEventArgs e)
 {
   GridCurrentCell cc = e.TableControl.CurrentCell;
   if (cc.ColIndex == 2)
   {
     try
      {
        int val = Convert.ToInt32(cc.Renderer.ControlText);
      }
      catch
      {
        MessageBox.Show("Invalid Number");
      }
    }
  }

Here is the minimal sample which implements this task.

Hi

I would actuality need to show the error in an error provider which is in the cell, so that the i don't need to use a message box.

Is that possible?

Hi Francois,

Sorry for the inconvenience caused.

You can supress error message from popup. Here is the minimal sample that shows the desired behavior for your reference:
