Grid Scroll Bar

[John]

Hi

Is there a way to force a vertical scroll bar on the data grid, even if the
data grid has no rows?

Thanks

Regards

No.

Yes, but as far as I know you need to do it all yourself. So if you plan on
reusing this sometime you can always just derive from the DataGrid and wire
in the logic yourself. You may need to make a few modifications to the code
below, but this should get you started.

public class MyDataGrid : System.Windows.Forms.DataGrid
{
public MyDataGrid ()
{
this.VertScrollBar.Visible = true;
this.VertScrollBar.VisibleChanged += new
EventHandler(VertScrollBar_VisibleChanged);
}

private void VertScrollBar_VisibleChanged(object sender, EventArgs e)
{
this.VertScrollBar.Visible = true;
}

protected override void OnResize(System.EventArgs e)
{
// TODO: Need to take caption height and some other aspects into
consideration.
this.VertScrollBar.Bounds = new Rectangle(this.ClientRectangle.Width -
this.VertScrollBar.Width, 0, this.VertScrollBar.Width,
this.ClientRectangle.Height);
base.OnResize(e);
}
}

I stand corrected then. Was this tested on Cx or VB.NET ?

This is C#, but shouldn't matter. I fully expect that this would run in a
VB.Net application (if translated, of course). And this could also be
written as a control in C# and then used in a VB.Net app - it's the beauty
of IL code.

This is a vb group and I am getting c# examples. as if vb.net wasn't
difficult enough.

Yes this example is in C#. But you posted your question to a whole bunch of
newsgroups and I am responding from the
microsoft.public.dotnet.framework.windowsforms.controls newsgroup. So there
is no language specification here. There are many C# to VB.Net converters
out there. Here is one:

Impressive. I used the converter and tried out your code. It works very
well.

Why not post the vb code here?

Thanks

Instantiate this at Form class level and remember to add it to the
form.controls collection

me.controls.add( InstantiatedGrid )


Public Class MyDataGrid
Inherits System.Windows.Forms.DataGrid

Public Sub New()
Me.VertScrollBar.Visible = True
AddHandler Me.VertScrollBar.VisibleChanged, AddressOf
VertScrollBar_VisibleChanged
End Sub 'New


Private Sub VertScrollBar_VisibleChanged(sender As Object, e As
EventArgs)
Me.VertScrollBar.Visible = True
End Sub 'VertScrollBar_VisibleChanged


Protected Overrides Sub OnResize(e As System.EventArgs)
' TODO: Need to take caption height and some other aspects into
consideration.__unknown
Me.VertScrollBar.Bounds = New Rectangle(Me.ClientRectangle.Width -
Me.VertScrollBar.Width, 0, Me.VertScrollBar.Width,
Me.ClientRectangle.Height) '
