Chart / Radgrid with Filter

[Andreas]

Hello

We where exactly following your DEMO example "grouping and aggregation" with chart and radgrid, which works fine so far.

But when we put a filter in the radgrid the values are not changing, means that the chart is always taking the full data, regardless of the filter in radgrid.

Is there a way to maintain a chart that is "listening" to the radgrid filter?

thanks Thomas

...i think it must work somehow when setting the ChartFilterDescriptor

I tried to do this in the FILTERED Event of my Radview.

But somehow i couldn't achieve so far how to convert a ColumnDescriptor of the RadGrid to a ChartFilterDescriptor

Can anyone help me on this?thanks

After i spend to much time on this filter issue i found the solution for myself

In radgrid.Filtered event just take the Filterdescriptor as they are and put them on the radchart

void RadGridView1_Filtered(object sender, GridViewFilteredEventArgs e)
        {

            RadChart1.FilterDescriptors.Clear();

            ///ColumnDescriptor durchgehen
            foreach (IFilterDescriptor Filter in RadGridView1.FilterDescriptors)
            {
                ///dein FilterDescriptor kann entweder ein DistinctValuesFilterDesc oder ein FieldDescriptor sein
                ///daher wird das Interface IFilterDescriptor verwendet, das funktioniert bei beiden
                ///im DistinctValuesFilterdescriptor stehen die Werte drinnen die benötigt werden
                ///
                RadChart1.FilterDescriptors.Add(Filter);
}
}
