gridview.selectedItem is null

[igal a]

i have this grid

 

 

<telerik:RadGridView x:Name="grid" ItemsSource="{Binding Path(ns:class.property)}"

 

 

 

SelectionMode="Single"

 

 

 

ShowGroupPanel="False" AutoGenerateColumns="False" CanUserDeleteRows="False" CanUserFreezeColumns="False" CanUserInsertRows="False" CanUserReorderColumns="False" CanUserResizeColumns="False"

 

 

 

RowIndicatorVisibility="Collapsed" Controls:StyleManager.Theme="Office_Black" EnableColumnVirtualization="False" EnableRowVirtualization="False" IsFilteringAllowed="False" Controls:RadControl.Theme="Office_Black" ReorderColumnsMode="None"
/>

now when i try to change selected item from code like this:

grid.SelectedItem = Collection[0];

the grid.SelectedItem stays null
even though Collection[0] is not null

i tried to call OnApplyTemplate before assignment but it didn't helped

i tried to do it with two way data binding and it didn't helped too

what can cause this?
and how can i solve it?

thanks

i solved it,
it was because the gridview wasn't loaded yet,

so i moved the init to the event handler of the RadGridView.Loaded event
and it worked
