I can't seem to get BringDataItemIntoView for 2009 Q1 release.

XAML

<

 

telerik:RadGridView Foreground="Black" MultipleSelect="True" Margin="0, 0, 0, 0" SelectionChanged="gvMainWorkQueue_SelectionChanged" CanUserReorderColumns="False" ShowGroupPanel="False" AutoGenerateColumns="False" Name="gvMainWorkQueue" Grid.Row="0" Grid.Column="0" AllowDrop="False" telerik:StyleManager.Theme="Telerik" />

 

 



Code

 

object currentRec = gvMainWorkQueue.SelectedItem;

 

gvMainWorkQueue.ItemsSource = GetDataSource();

 

gvMainWorkQueue.Rebind();

 

 

 

if (currentRec != null) {

 

gvMainWorkQueue.SelectedItem = currentRec;

gvMainWorkQueue.BringDataItemIntoView(gvMainWorkQueue.SelectedItem);

}

no errors occur.  The grid doesn't auto scroll to bring the item into view. 
Also not having any luck with 2009 Q2.

Hi Brian,

We would like to apologize for this behavior. We are aware of this issue, but unfortunately there is no workaround possible at this time.

With our Q3 Release (early November) we will be introducing our brand new virtualization mechanism and the BringItemIntoView method will be replaced with the ScrollIntoView method, which should behave correctly.

On a side note, when you upgrade to the Q3 Release make sure that your business object class has the Equals method overridden so that after you rebind the grid the cached SelectedItem would be matched against an item from the new data source. In other words, since the data item references will be different (even though they point to the same logical data), the class will need an Equals method to compare the two references and decide that they are equal , i.e. for this line to work:

gvMainWorkQueue.SelectedItem = currentRec;

Please, excuse us for the inconvenience.

Regards,
Ross
