DataGridBoolColumn

Here is what I wound up with. I think it is a simpler approach. public class SingleClickDataGrid : DataGrid { public SingleClickDataGrid() { this.MouseDown += new System.Windows.Forms.MouseEventHandler(this.GridMouseDown); } public void GridMouseDown(object sender, MouseEventArgs e) { System.Windows.Forms.DataGrid.HitTestInfo hi; // let's see where we clicked... hi = HitTest(e.X,e.Y); // If the user did not click on a cell, we don't care... // we'll just pass on to the base class if(hi.Type == System.Windows.Forms.DataGrid.HitTestType.Cell) { // Get the TableStyles collection DataGridTableStyle dgt = TableStyles[0]; // Get the ColumnStyle for the selected column DataGridColumnStyle myCol = dgt.GridColumnStyles[hi.Column]; // Is this a check box column? // if not, we'll let the base class handle it if(myCol.GetType() == typeof(DataGridBoolColumn)) { // First part of the magic... select the row, so that the edit can happen Select(hi.Row); // Call the grid table style to start and end the edit dgt.BeginEdit(myCol,hi.Row); dgt.EndEdit(myCol,hi.Row,true); } } } }
