InvalidOperationException: A style intended for type 'Telerik_Windows_Controls_RadTileViewItem_0_123599943' cannot be applied to type 'ContentPresenter'.

What is this supposed to mean?  This appears to pop up randomly, and now I cannot get it to go away..

Hello!

At the Reorder-Drag&Drop there are 3 options to reorder the Tasks: "Before", "Inside" and "After". Is there a possibility to disable "Inside" and "After", so the user only has the option to reorder "Before"?

kind regards

Hi, 

Is it possible when using the standard DateTimePicker to dynamically change the StartTime/EndTime properties of the Time-part of the control?

I would like the user to be able to click f.ex. 9:00 in the TimePicker, after which this same Time-picker part displays 9:05, 9:10, 9:15, 9:20... until 10:00

(a bit the same like for the Date-picker part - where you can choose the year, then month, then date ....)

Is that something that can be done?

Hi,

We would like our users to perform "undo/redo" in the GridView (at the very least, "undo") as in Excel where users can "undo/redo" changes in each cell.

Could you please help in providing an example of how to accomplish this scenario?

We are using MVVM with observable properties and observable collections.

Kind regards

I need to display grid filters with both an image and descriptive text.  I've searched the forum and found numerous examples for adding the image, but none with both image and text.

Is this possible?  if not, can I reduce the width of the filter dropdown to avoid the "ugly" whitespace in my filter list?  There is really no need to include the "Apply" and "Clear" filter buttons as the check boxes auto apply the filters when checked or unchecked.

Here is what I have so far:

    public class ImageFilterColumn : GridViewImageColumn
    {
        protected override Func<object, object> FilteringDisplayFunc => CategoryToFilterImage;

        public static object CategoryToFilterImage(object value)
        {
            var rtn = new object();
            var cat = (LogCategory) value;
            var image = new Image() {Source = new BitmapImage(cat.ToSmallImageUri())};
            return image;
        }
    }

xaml:

 <telerik:RadGridView.Columns>
 <local:ImageFilterColumn ShowFieldFilters="False" Header ="" DataMemberBinding="{Binding cat, Converter={StaticResource CategoryImageConverter}}"/>

for example, 

Series 1:   X: P1 P1 P2

                 Y   2   3  4     

Series 2   X:P1 P1 P2

                Y: 5   6   7

If they are plotted in graph as bar series. I expected the plot order as (series1 ->P1,2) (series2->P1,5) (series 1->P1,3) (series 2->P1,6) (series1 ->P2,4) (series2 ->P2,7) . that means all the P1 category  will be grouped together and has the value order  as (2,5,3,6). And P2 category has value order(4,7)

but actually, it looks like P1 category  has the value order as (2,3,5,6)   and P2 category has value order(4,7)

in order to achieve what I want, I have to flatten the two series (series1 and series 2) into one series. But that approach is not exactly what I want. Thank you
