I’m binding a Datagrid with button(template column).

On ButtonClick event I’m changing the Grid Datasource and binding again.
that’s working fine.
But what happening is the button which I pressed(strictly that index) disapperas.

Let me know whether it is the bug or else??

–Thankyou

My main page contains a TabControl. The TabControl has a single customer UserControl (as TabItem) loaded. This UserControl has two ListBoxes. The User selects an item in ListBoxA and ListBoxB populates. The user then clicks an item on ListBoxB and the page loads a new customer control as a tabItem in the TabControl. Only, it doesn’t, it errors.

The new custom control can be loaded directly and it loads fine, but if loaded as the result of this list box being selected, then it falls over.

Am more than happy to share my project if that helps…

Error is as follows:

any idea???

any idea???

Please use Silverlight 2 beta2. SL2b1 is obsolete now.

One of the strangest thing is the silverlight control works in my test application but not the actual application
(I am using silverlight control in my ASP .Net web site)

Any help will be appreciated

I’m not sure if this issue was notified before, but:

Step 1. Create one control C1 that contains a check box.
Step 2. Inside the main page for example, create an instance of C1 on Loaded, then execute the following code on a button click:

LayoutRoot.Children.Clear()
LayoutRoot.Children.Add(instanceOfC1)

Step 3. Run the application.
Step 4. Click the button to add the control.
Step 5. Check the check box inside instanceOfC1
Step 6. Click the button again. The same instance will be re-added to LayoutRoot.Children.
Step 7. Try to uncheck the check box.

Result -> the state remains checked, but the check box has actually become unchecked.

Enabled/Disabled items also behave awkwardly in this setup.

I should have sent this one to you a while back to add to the list. (http://tocode.blogspot.com/2008/04/silverlight-2-textblock-responds-to.html) Basically if you have text that overflows a TextBlock and is visually truncated by a Height or MaxHeight, the overflow area still throws mouse events. A workaround is to add a clip to a bounding object.

It has been verified by Joe Stegman to be a real bug but is supposedly fixed in Beta 2.
