Custom DataGridViewTextBoxColumn & DataGridViewTextBoxEditingControl

[Gohalien]

Hello, I am trying to makethat user will be unable to enter a "," in a cell

What I was thinking was to make a custom columntype, and indeed, I created it, I have to override OnKeyPress event.

So, I was doing the following:

public class MyCustomControl : System.Windows.Forms.DataGridViewTextBoxEditingControl
{
protected override void OnKeyPress(KeyPressEventArgs e)
{
if (e.KeyChar == ',')
{
base.OnKeyPress(e); //Ok
}
else
{
e.Handled = true; //Deny
}
}
}
 
public class TextBoxWithoutComma : System.Windows.Forms.DataGridViewTextBoxColumn
{
//I dunno what to put here to use my current control
}

Anyway... I am just trying now when I create the "num" column to use my current control... not working..

this.dataGridView1.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] {
            this.num});
this.num.HeaderText = "Number";
            this.num.Name = "num";
            this.num.DataGridView.EditingControl += new  System.Windows.Forms.DataGridViewTextBoxEditingControl(myCustomControl.nCampoGrillaC); <- error
