IsChecked is not working

[naveen]

Silverlight Version installed  - Silverlight 3.0 Beta.

Hi,
I want to make context menu mutually exclusive checkable, however if i checked one item other item is not becoming unchekced. I am using following function to unchecked other items

 

 

private void UnCheckedOtherItems(RadMenuItem selectedItem)

 

{

 

for (var i = 0; i < itemMenu.Items.Count; i++)

 

{

 

var container = itemMenu.ItemContainerGenerator.ContainerFromIndex(i) ?? itemMenu.Items[i];

 

 

var separator = container as RadSeparator;

 

 

if (separator != null)

 

{

 

continue;

 

}

 

var subItem = container as RadMenuItem;

 

 

if (subItem != null && subItem.Equals(selectedItem))

 

{

subItem.IsChecked =

false;

 

}

}

}

Your help will be highly appreciated.

Hello ncv,

I prepared a simple example demonstrating the best way to create "radio-button" menu items. It uses a ViewModel that contains the logic for the radio buttons and the groups, and a RadMenu that is data-bound to that model. The application is Silverlight 2, but the code should be exactly the same in Silverlight 3, so I hope you will not have problems using it.

All the best,

Thanks Valeri,

Samples is running fine for both Checkbox and Radio Button Options, however I have seen some issue with Radio buttons items which was my exact requirement. E.g. Suppose I click  at Radio Button 1.1. and after that I click at Radio Button 1.2, First clicked item is not showing unchecked i.e. still checked. It refresh when I focus in Radio Button 1.1.

Can you please suggest me the way to resolve it.

Hello NCV,

If I understand correctly, the behavior you are observing could be related to a bug in Silverlight 3 Beta. Unfortunately I only have a virtual machine with an unofficial build of Silverlight 3 from Microsoft and it will take some time to prepare a VM with the public beta to check if it has the same problem. I shot a short movie on my existing VM, please let me know if I am missing something.

Yes Valeri,

You are right, it could be bug in silverlight 3. Right now I m using Version 3.0.40307.0.

In your demo the working of radio button is woriking perfectly, however in my case it is not.

Now what you suggest?

Hi NCV,

I will check what's wrong with the menu and if it can be fixed, I will include the fix in the internal build next week. However, I would recommend waiting for the official release of Silverlight 3 that is scheduled for July 10:
