When the datagrid has multi rows and the vertical scrollbar hasn't appeared,
if I click the column near the bound or drag horizontal scrollbar, this
exception will be throwed. The trace stack as follows:
at System.Windows.Forms.DataGrid.CreateScrollableRegion(Rectangle scroll)
at System.Windows.Forms.DataGrid.set_HorizontalOffset(Int32 value)
at System.Windows.Forms.DataGrid.ScrollRight(Int32 columns)\
at System.Windows.Forms.DataGrid.ScrollToColumn(Int32 targetCol)
at System.Windows.Forms.DataGrid.EnsureVisible(Int32 row, Int32 col)
at System.Windows.Forms.DataGrid.set_CurrentCell(DataGridCell value)
at System.Windows.Forms.DataGrid.OnMouseDown(MouseEventArgs e)
at System.Windows.Forms.Control.WmMouseDown(Message& m, MouseButtons button,
Int32 clicks)

at System.Windows.Forms.NativeWindow.DebuggableCallback(IntPtr hWnd, Int32
msg, IntPtr wparam, IntPtr lparam)

System.Windows.Forms.ComponentManager.System.Windows.Forms.UnsafeNativeMethods+IMsoComponentManager.FPushMessageLoop(Int32
dwComponentID, Int32 reason, Int32 pvLoopData)
at System.Windows.Forms.ThreadContext.RunMessageLoopInner(Int32 reason,
ApplicationContext context)
at System.Windows.Forms.ThreadContext.RunMessageLoop(Int32 reason,
ApplicationContext context)
at System.Windows.Forms.Application.RunDialog(Form form)
at System.Windows.Forms.Form.ShowDialog(IWin32Window owner)
at System.Windows.Forms.Form.ShowDialog()
..
..
..
My datasource is a datatable.
IDE: .net 2003 + framework 1.1 + sp1
Does anyone know whether this is the DataGrid own bug?
What can I do to workaground it or resolve it?
Thanks.
