How can you detect if the GroupHeader was clicked?

[jholt]

I have two identical  WPF RadGridViews on my form. I want to be able to detect when the GroupHeader has been clicked so that
a) Only one group on each grid is expanded at any one time
b) If the group in radGridDebits is expanded/collapsed, the same group in radGridCredits is expanded/collapsed - i.e. synchronize the group header between both grids.
c) Basically, I'm looking for a GroupHeader.Clicked event but can't find it!!

<Controls1:RadGridView Grid.Row="1"
                            x:Name="radGridDebits"
                            AutoGenerateColumns="False"
                            ShowColumnHeaders="False"
                            IsReadOnly="True"
                            ItemsSource="{Binding Data}"
                            ShowGroupPanel="False"
                            RowIndicatorVisibility="Collapsed"
                            AutoExpandGroups="False">

Hello jholt,

You may try to use the two events raised once a particular group is being expanded or collapsed:

private void gridView_GroupRowIsExpandedChanging(object sender, GroupRowCancelEventArgs e)
{
}
private void gridView_GroupRowIsExpandedChanged(object sender, GroupRowEventArgs e)
{
}

 
However, those events are available in our Latest Internal Build.

Kind regards,

Hello jholt,

You may download the Latest Internal Build from your Telerik account. However, the mentioned events are available in our official versions as well since the Q3 2010 SP1 release.
