dataGridView default error dialog handle
0
I am trying to hide default datagridview error dialog.
I put in the code this event handler:
this.dataGridView2.DataError += new System.Windows.Forms.DataGridViewDataErrorEventHandler(dataGridView2_DataError);
private void dataGridView2_DataError(object sender, DataGridViewDataErrorEventArgs e)
{
//empty so it doesn't show anything
}
But still when i try this and leave datagridview cell empty ( delete everything from it), it show me dialog box with error.
Screenshot of error:
c# datagridview

Can we assume that you get your names right and have indeed hooked up one event to both DGVs?

private void dataGridView2_DataError(object sender, DataGridViewDataErrorEventArgs e)
{
e.Cancel = true;
