Hi.

Is it possible to have a RadGridView with Grouping, Virtualization and still have Content based scrolling (CanContentScrol=true)?

We have a rather big List of Items with unequal height. The List is dynamically managed based on the state of an external peripheral. List Items are added or removed when the state of the peripheral changes. This leads to unwanted movement of the Items in the List.

We are trying to encounter Item movement when the List changes. We implemented a solution similar to this one: Keep Selected Item in Viewport when Collection Changes - Telerik UI for WPF 

But when enabling Grouping or Sorting, the RadGridView seems to change to pixel based scrolling instead of Item based scrolling. Then it seems the above solution is not working anymore, because the Offset then needs to be given in Pixels instead of Items.

Is it possible to have Item based scrolling despite Grouping or Sorting?

Else is it possible to get the height of the inserted/removed Item to calculate the offset needed, even if Virtualization is enabled?

Or is possibly some other approach better suited?

In the HtmlExportSettings there is no valid ImageExportMode that word is compatible with as it is not able to display Base64 encoded images.

Is there another ImageExportMode that is compatible?

OR

Is there a better solution to insert images from RichTextBox into a Microsoft word document? Possibly, create RadDocument from the word document I have and replace it in the RadDocument and do conversion to Microsoft word document?

Open to suggestions.

Hi , I'm trying to automate the testing of a WPF program by writing code. I can perform actions on the main window of the program, but I can't do it on a different window. I think the reason for this is that it doesn't recognize that window. However, I couldn't find out how to switch to a different window.Can you help me ?. Here's an example of the code I've written:
        [CodedStep(@"Type 'XXX' into ServerNameWatermarkTextbox")]
        public void ConfirmInstalledDate_CodedStep()
        {
            string formattedDate = DateTime.Now.ToString("yyyy-MM-dd");
            ActiveApplication.MainWindow.Find.ByName("serverNameWatermark").User.TypeText("XXX",2);
            ActiveApplication.MainWindow.Find.ByName("usernameWaterMark").User.TypeText("logadmin",2);         
            ActiveApplication.MainWindow.Find.ByName("usernameWaterMark").KeyPress(ArtOfTest.WebAii.Win32.KeyBoard.KeysFromString("Tab"),1,1,1);
            ActiveApplication.MainWindow.Find.ByName("pwdBox").User.TypeText("XXX",2);
            ActiveApplication.MainWindow.Find.ByName<Button>("btnSignIn").User.Click();
            System.Threading.Thread.Sleep(5000);
            ActiveApplication.MainWindow.Find.ByName("imgData").User.Click();
            ActiveApplication.MainWindow.Find.ByTextContent("Status").User.Click(MouseClickType.RightClick);
            ActiveApplication.MainWindow.Find.ByTextContent("Select columns").User.Click();
            ActiveApplication.GetWindow("Select columns");
            ActiveApplication.GetWindow("Select columns").Find.ByName("txtSearch").User.TypeText("Date",2); 
            System.Threading.Thread.Sleep(5000);
            ActiveApplication.GetWindow("Select columns").Find.ByName("txtSearch").User.KeyPress(System.Windows.Forms.Keys.Enter,1);
            ActiveApplication.MainWindow.Find.ByTextContent("^"+formattedDate).User.Click();
            System.Threading.Thread.Sleep(2000);
        }
    }

How can I bind a property to RadRichTextBox FontSize and FontFamily? I get errors saying the property types don't match but they do. FontSize property is double and FontFamily property type is FontFamily. Any ideas?

Hello,

I would like to add a slide button under the tile view like screenshot.

How can I add a button under the tile view?

Thanks for your feedback.

I have a simple NumericUpDown control showing milliseconds.  I use a 'ms' custom unit to show alongside the number. 


It looks good but as soon as hit the + or - key, the 'ms' disappears and I have just a number.  This is because hitting +/- gives keyboard focus to the edit box -- activates the cursor in there and all that.    Once I click somewhere else focus leaves the edit box, the 'ms' re-appears.

Is there a property or some simple way that would let me prevent this behavior?   I want +/- to just change the number without grabbing the keyboard focus.  

Note that I do still want the number to be user-editable if they actually go to the trouble of clicking directly in the edit box itself.  I just want to stop +/- from doing that for me.

ChartView experiences frequent garbage collection in TrackInfoUpdated after Tooltip of any control is activated.

i have a combo box that i need when i select one of it's items, it will open a new sub combo box to choose a sub item

 

is it feasible?

The Telerik WPF ScheduleView's appointment cells have a problem with intersecting times when assigning schedules within a one-minute timeframe. For example, when I drag and drop to assign a schedule like 12:30 PM - 1:30 PM, and then another schedule from 1:30 PM - 2:30 PM, sometimes it displays two cells in one column (as shown in the right corner), while other times it functions correctly (as shown in the left corner).

I must emphasize that this is a bug in the user interface. Is there a way you can address and fix this issue? Thank you!

I have found this documentation online in order to extract and modify the default template style for telerik controls.

https://docs.telerik.com/devtools/wpf/controls/radrichtextbox/styles-and-templates/styling-radrichtextbox#:~:text=To%20copy%20the%20default%20style%2C%20load%20your%20project%20in%20Expression,Style%20%2D%3E%20Edit%20a%20Copy.

I've done this many times on standard WPF controls so I am familiar with the process. When I open project, I get the below options. There is no option to edit style and edit a copy.
