Hi Kan,
you can access the toolbar controls by it's index. here is the example to
disable the first button.
' Toolbar1 is my tool bar.
Toolbar1.Items(0).Enabled = False
*Toolbar1.Items.Count - you will get the no of controls in the toolbar1.
cheers

Hello
Thanks for reply.
I try this before by using Toolbar1.Items(0).Enabled = False and disable
the button.
but my tool bar is in an ascx file and I want to disable it in the
Page_load event of its hosting page(i.e. aspx.cs file)
I get the error :
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set
to an instance of an object.
I can't solve it.Please help

Kan,
You will have to expose the ToolBar1 as a public class rather than
protected from your *.ascx:
public SomeToolBarClassName ToolBar1;
Then you can do:
userControl.ToolBar1.Items(0).Enabled = False
Remember that when you make an *.ascx, all the controls on the
*.ascx are treated as if they are in their own little world and inaccessible
to outside code except the by the [code] interfaces that you create, whether
it is simply declaring an object instance public or tying individual
properties to the properties of controls within the UserControl.
HTH,
- Chuck
