Hello, I would like to set the MaxLength property of the textbox part of a ComboBox cell and a GridListControl cell in a virtual grid. I've tried to set the MaxLength property in the QueryInfoCell event - the length isn't limited. I've tried to set the MaxLength property of the TextPart of the renderer in the PrepareViewStyleInfo event - the length isn't limited either. Could you give me some advises please ?

Maybe you could use the CurrentCellKeyPress event. In it, identify the cell somehow and check the current length and set the e.Handled to true to ignore the keystroke.
private void gridControl1_CurrentCellKeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
	GridCurrentCell cc = this.gridControl1.CurrentCell;
	if(cc.RowIndex == 2 && cc.ColIndex == 3 && cc.Renderer.ControlText.Length >= 4)
		e.Handled = true;
