RadGridView GroupRow - click event

[Florin]

Hello,

It is possible to add an event on groupRow ? I want - when i click on groupRow - to stop collapsing/expanding and to access some how the information stored groupRow and on double click event to have his normal functionality.

So far I have managed to add an event, but I don't have access to the object in groupRow. For this i use the code:

this.AddHandler(GridViewGroupRow.MouseLeftButtonUpEvent, new MouseButtonEventHandler(this.GridViewRow_OnMouseLeftButtonUp), true);

Best wishes,
Florin

Hi Florin,

Would you please shed some more light on your requirements? What do you mean by mentioning "information stored in group row"? In case you have visual elements in mind, you can access them by searching for them in the visual three. For instance, since the default visual element displayed in GridViewGroupRow is a TextBlock, you can access it like this:

clubsGrid.ChildrenOfType<GridViewGroupRow>().First().ChildrenOfType<TextBlock>().First();

 The approach is similar if you have defined a GroupRowTemplate.

Hello,

I mean, if i had a RadGridView with three columns ID, LastName and FirstName and I drag the column LastName into group section, the RadGridView component make a group by LastName. So when i click on the grouped row (lastName) i want the behavior described on first post. On click event i want to take the ID.

Best wishes,
Florin

Hi Florin,

You can get the information for the group row by getting its GroupViewModel and examining its properties. For example:

this.AddHandler(GridViewGroupRow.MouseLeftButtonUpEvent, new MouseButtonEventHandler(OnMouseLeftButtonUp), true);


        private void OnMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
        {
            FrameworkElement clickedElement = e.OriginalSource as FrameworkElement;
            GridViewGroupRow groupRow = clickedElement.ParentOfType<GridViewGroupRow>();
            if(groupRow != null)
            {
                GroupViewModel groupViewModel = groupRow.GroupViewModel as GroupViewModel;
            }
        }

Considering the double click functionality, you could try to implement the idea illustrated in this forum thread (you can use the DoubleClickOnRow-Behavior.zip project) . In your case, however, you will work with GridViewGroupRow, not GridViewRow.


All the best,
