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?

I have a dynamically generated document in a RadRichTextBox. When I print this document, the quality (graphics) is very bad.

If I export the document as pdf and print the PDF document, then the print quality is fine.

How can I improve the print quality of the RadRichTextBox?

Dear All,

I am new to Chat control. I am practicing RadChat in Chat application, such that I have list of contacts on Left side, which bounded to List of users where

I have bounded RadChat DataSource as SelectedUser.Messages property, where SelectedUser is public property in my viewmodel, which contains selected item object.

As I assume that RadChat need to updated Messages as datasource is changed, but instead of refreshing messages, it appends new messages to old one.

My requirement is to Clear all messages in Chat UI, as I have selected new Messages object as datasource.

Here I want to clarify that data in Messages are correct according to my need. I feel it is some issue in RadChat or I need further steps to acheive my target.

When maximizing dockable windows on a second monitor they get cut-off. See attachment. This only happens, when the second monitor has a higher resolution, than the main monitor. Maximizing on main monitor or my third monitor which is smaller it works fine.

You already had a similar bug, which was obviously only fixed for the main monitor resolution:

My Telerik Version: 2018.1.220.45

Please get this fixed.

Good morning
I have a problem that I can not solve despite having read many threads about this topic.
I have a RadGridView with binding to table where are listed a series of processing steps coming from an external microprocessor.
the running process is always on the first line.

Faced with a change in the status of some microprocessor values, which occur with a few milliseconds, refresh the values of the only cells that interest me with these instructions (for reasons of display speed):

   ((WorkPhaseInProgress) RadGridViewWorkPhaseInProgressOnDashBoard.Items [0]). QtaDone = qtaDone;
   ((WorkPhaseInProgress) RadGridViewWorkPhaseInProgressOnDashBoard.Items [0]). QtaPartialDone = qtaPartialDone;
   ((WorkPhaseInProgress) RadGridViewWorkPhaseInProgressOnDashBoard.Items [0]). QtaDoneForHour = qtaForHourNow;
   RadGridViewWorkPhaseInProgressOnDashBoard.Items.Refresh ();

where

RadGridViewWorkPhaseInProgressOnDashBoard is the name of the RadGridView

WorkPhaseInProgress class of single item

and everything works perfectly.

my question is:
how can I change the backgroud color for a few seconds to the only cells that interest me?

I can run everything in a separate thread, but my problem is how to change freely (according to my logic related to the microprocessor) the change of back color.
I hope I explained myself
thank you in advance
