EditingControl_OnChanged event of a DataGridView

[Luceafaru]

Hello,

How can I trap the OnTextChanged event of a textbox hosted by a DataGridView?

What I actually want is, while the user is in the first column, in editing mode, once the entered text.lenght = 3 to automatically end editing and move focus to the next column.

I thought that checking the lenght of the entered text in the underlying textbox (my first column is type textbox) would do it, but there is no such event.

Any help greatly appreaciated,

Kind regards,
Paul

I found it myself.
One solution is adding an event handler in the EditingControlShowing event:

private void myGrid_EditingControlShowing( object sender, DataGridViewEditingControlShowingEventArgs e )
{
    //Add an event-handler while in editing
    TextBox txt = e.Control as TextBox;
    if(txt !=null)
    {
        txt.TextChanged -= new EventHandler(TextBox_TextChanged);
        txt.TextChanged += new EventHandler(TextBox_TextChanged);
    }
 
}
 
void TextBox_TextChanged( object sender, EventArgs e )
{
    //Code to handle TextChanged
}
