Master / Detail with RadGridView

[Andrea Rapuzzi]

Hi,

I would like to achieve a master detail scenario where the user select a row in a RadTreeListView and the details will be shown in a RadGridView using binding.

My RadTreeListView is binded to an observable collection, I also tried with a QueryableCollectionView but I wasn't able to bind the RadGridView with the RadTreeListView selected item.

The source for the details is an observable collection that is a property of the source for the RadTreeListView.

I'm using Prism and I would like to follow the MVVM pattern if possible.

Thanks !!

Hi,

 If your details data are property of the data item in the collection bound to the treelistview you can simply set:

<telerik:RadGridView ItemsSource="{Binding SelectedItem.MyChildData, ElementName=RadTreeListView1}" ....

Perfect,

it works fine !

Thanks Vlad

But now I have another problem ...

In my RadTreeListView I have a column with a cell template, the column is a GridViewDataColumn and it's binded to a bool property in my ObservableCollection. The cell template use a converter in the binding that if the value is true return an ImageSource. At this point it's all ok, I can filter and sort by that column. The problem occours when I filter with the builtin filter button on the header, because the filter window shows only the false value in the list. Then when I click on the checkbox the filter action occours has expected, but when i click again to uncheck, without exiting the filter window, the RadTreeListVieew does nothing. At this point if I close the filter window I see the filter applied and if I click again on the filter button the RadTreeListView refresh its content and open the filter window with the false checkbox unchecked.

Thanks

Hello Maya,

thanks for your sample, but it has the same issue I've explained before ...

I've found a couple of issue, I'll give you the step to reproduce them with your example

1. 1. Open the Nationality filter window
1. 2. Click on the Images/spain.jpg checkbox (the radtreelistview filter as expected)
1. 3. Click again on the same checkbox (the radtreelistview does nothing, the Select All checkbox still have the minus sign)
1. 4. Click on the Filter and / or Clear Filter button (the radtreelistview does nothing)
1. 5. Close the filter window
1. 6. Reopen the Nationality filter window (the radtreelistview now reset the data and the filter)

2. 1. Repeat step from 1. 1. to 1. 5.
2. 2. Open the Country filter window
2. 3. Click on Select All
2. 4. Uncheck England
2. 5. Uncheck Spain
2. 6. Close the filter window
2. 7. Open the Country filter window again : Crash ! unhadled exception

Thanks for your help !
