Hi,

 

i use c#/wpf RadGridView. I bound i Collection calls to my RadGridView. Here i have a RadGridViewDataColumn with a cell template checkbox.
My problem ist that i have perhaps 10 items in my collection with the same telephone-no. if i check one of these items i want to check the rest of
the items in my collection with the same no. too. Also if i uncheck one, i want to uncheck the rest to. How can i do this?

 

Thanks

Rene

Hi Rene,

You can attach to the Checked/Unchecked events of the CheckBox and in the event handlers iterate over the items of the RadGridView and manually check/uncheck the similar items. I have attached a sample for your reference.

Thanks Stefan,

that's it! This was very helpfull. But know if add a new item during runtime, the RadGridView is not updated. I have to restart
the application and than i see my new entry. I tried to rebind the Grid, but without success.

Thanks

Hi Rene,

It seems that the RadGridView is not notified that a new item is added to your source collection. You can consider using an ObservableCollection.
