I've got a map that's initialized to a certain area by a call to SetView, and the zoom-level ends up at 4. I've also got a bunch of predefined areas to jump to, and we do this by calling SetView with a LocationRect. I've noticed that when the SetView-call ends up zooming in to level 19, 20 or 21, no map tiles are loaded and the view is empty. I have to zoom out to level 18 until they are loaded. The MiniMap looks right though. Any idea what could cause this behaviour? Once i have zoomed out to level 18 I can jump to level 19-21 with map-tiles showing.

I'm using the suggested HttpsOpenStreetProvider from this thread: https://www.telerik.com/forums/openstreetmapprovider-through-https

Hello,

      I.m using GanttView to display my MS Project and I wish to highlight a critical task by setting the corresponding item's background color to Yellow. I've looked up the documentation and tried the RowHighlightContainer, but that seems only changes the behavior when MouseOver and not working with the highlighted items. By the way, I've already  the critical tasks to HighlightItemSource Property. Any suggestions?

Here's a snippet of my code:

Dear Team,

I am facing issue with Chat Control. When I tried to change datasource of control, Messages in Chat UI does not reflect.

I have List of User in listbox. Each User has Observable collection of TextMessages. When User selection changed, I bind datasource to selected user messages. I assume that Chat control will update its UI by selected User messaged. But it is not working.

I tried to clear MessageListItems on selection change, and re-bind datasource to selected user's messages. In this case Chat UI does not show any messages.

For reference I have uploaded my sample project on Google drive.

Messenger App

@Admin: I had already shared the same issue few days ago, but i did not receive any solution.

I have a tree list view with the following child table definition:

        <telerik:RadTreeListView.ChildTableDefinitions>
            <telerik:TreeListViewTableDefinition ItemsSource="{Binding Children}" />
        </telerik:RadTreeListView.ChildTableDefinitions>

When an item that the tree list is bound to updates its child collection, the selected cells in the grid are lost. In our situation, the selected cell is on a row that is affected by the children changing.

Is there any way to prevent the selection from changing when the rows reload as a result of the structure changing? Or, failing that, any way to determine that the hierarchical structure is changing other than the row load and unload events? The grid is virtualized as well, so we can't tell how to distinguish between rows unloading because they have scrolled out of view, vs the hierarchical structure changing.

Hi,

Is it possible to edit GridViewComboBoxColumn to display 2 textblocks in each comboboxitem and bind text value for both textboxes to some properties of a class?

I have added a screenshot to help understand the issue

Hi Telerik team,

the forum search doesn't work!

Every keyword leads to null result

Please fix it.

Is this possible?
