filtering funnel onclick event

[Hector Hernandez]

I need to know when the user clicks on the  filtering funnel button and the filtering window is about to open. Is there any event I can attach to without creating my own filter template? I just need to know when a user is clicking there and that's it.

Thanks!

Hello Hector,

The "funnel path" is actually the content of a ToggleButton, which is named as "PART_DropDownButton" in the template. Try searching for them in the visual tree and subscribe to their Click event. You may achieve this like this:

clubsGrid.ChildrenOfType<ToggleButton>().Where(tb => tb.Name == "PART_DropDownButton");

Hi Ivan, thanks for the super fast answer.
I am indeed using your approach:

var x = ScenariosGrid.ChildrenOfType<ToggleButton>().Where(tb => tb.Name == "PART_DropDownButton");

but this is not returning any related control.
Now, I tryied also:

var x = ScenariosGrid.ChildrenOfType<ToggleButton>();

with no success, and finally:

var x = ScenariosGrid.ChildrenOfType<Control>().Where(tb => tb.Name == "PART_DropDownButton");

all of them with no result whatsoever.
In a Final attempt I tried to do this

GridViewCheckBoxColumn column = ScenariosGrid.Columns["Succeeded"] as GridViewCheckBoxColumn;
var y = column.FindChildByType<ToggleButton>();

again with no successful result. In fact, the latest code chunk throws back an exception.

Thanks for any support! will keep testing.
