5.47 How can I make my last column wide enough to exactly occupy all the client area of the datagrid?
If you have added a TableStyle for your grid, then the code below should set the right column width to be the empty space from a button click. If you need to dynamically do this in response to the user sizing other columns, then there may be more work. But if you only need to do it at the end of your Form_Load, then this code might be sufficient. It assumes your datasource is a datatable. You can download a sample project (C#, VB).

public class cls_GridDblClick
{
DataTable _Dt;
DataGrid _Dg;
public delegate void Grid_DoubleClick(object sender, MouseEventArgs e);
public event Grid_DoubleClick _DoubleClick;

TextCol.MappingName = "custName";
TextCol.HeaderText = "姓名";
TextCol.Width = 100;
