Hi,

I have a Gridview and a Chart. The gridview can be filtered. what i would like is the chart to update its view based on the filter applied by the user but I cannot see how to bind the chart to the filtered list.

//Load data and bind to gridview

 

 

ObservableCollection<People> peopleByYearData = GetPeopleByYear();

 

gridViewPeople.ItemsSource = peopleByYearData;

//this displays the data on a simple bar chart.

 

chartPeopleByYear.ItemsSource = gridViewPeople.ItemsSource;

How do i ensure that the chart updates its view when the gridview is filtered?

i have tried hooking into the Filtered event of the gridview to try and get access to a list of filtered items but I cannot find any such list. The filter displays fine on the gridview but in the Filtered event the gridViewPeople.Items.Count is always == 0.

Thanks

Hello ben williams,

After you perform filtering , the Items property of RadGridView should contain the list of filtered items you need.

Thanks for your prompt reply- typically i discovered  a typo pointing to the wrong GridView which had no items. Gah!
