I am using a "RadTreeView" control where I have declared an event which handles the formatting of the node and also have NodeExpandedChanged event.

The main purpose of the NodeFormatting event is to control the Expander image

private void tvwDocuments_NodeFormatting(object eventSender, TreeNodeFormattingEventArgs eventArgs)
        {
            RadTreeNode Node = eventArgs.Node;

			//Check if Node is the root node, else check if it has no children, and set expand/collapse state accordingly
			if (Node.Parent == null)
			{
				eventArgs.NodeElement.ExpanderElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed; //Collapsed hides the element completely, hidden just makes it not visible but maintains spacing for it
			}
            else if (Node.Nodes.Count == 0)
            {
				//Disable drawing of the sign image, then set its size to 0 so that the lines are drawn underneath.
				eventArgs.NodeElement.ExpanderElement.SignImage = null;
				eventArgs.NodeElement.ExpanderElement.SignSize = new Size(0, 0);
			}

In my application I have a tree that looks something like the attached image (Tree Structure.png). From the image it will be evident that all nodes are expanded.

The issue what I am facing is, when all nodes are expanded and when the very first node of the parent is collapsed; all the respective nodes "ExpanderImage" is blank. (please refer attached screenshot (UpdatedTreeStructure.png))

Hello I am trying to make the column that gets data from a database have a linkable modal. For privacy reasons full copy of the code isn't available. However I have cropped up this segment in particular since this is the issue I am trying to fix. I can already bind data from the datasource to a column and data displays correctly when I remove the parts to make it "linkable". hence this is why you might notice some of the parts are in comments. Simply put I need to make the column display the data from the database then make it linkable pointing to a view and a controller. Hopefully someone will be able to answer the soonest. Thanks in advance!

Hi,

I'm developing an application with the Telerik WPF controls and I'm reading a lot of your documentation pages (half a day). 
Every few seconds this ninja animation 'Is this article helpful' question is flying in on the right side.

Maybe it is fun and it is cool for you to develop this animiation with this ninjy, but it is not following any UX pattern.
It is making me crazy!

Please remove it!
I'm not able to work with your documentation as long as you bother me with that.
And I think nobody is using this kind of feedback tool.

So remove it.

Best regards and thanks

Dirk

I was perusing your purchase page https://www.telerik.com/purchase.aspx?filter=web and noticed some very interesting English.  Down at the Source Code row in the package comparisons, I read this:

   "Components source codes included for all products without Telerik UI for .NET MAUI, Telerik UI for Xamarin and Telerik JustMock"

So, source code is included for all products except Telerik UI for .NET MAUI, Telerik UI for Xamarin and Telerik JustMock?

Thanks,

_D

Hello There,

I have a similar DropDownTree in my project.

I do not want to use clearButton, I would like to create a button with onClick clear out selected values and also the checkBox selection.

What I have tried: the used selectedIds= [] but on UI the tags stucked there, can not removed at all.

Thanks for your help!

Cheers,
Peter

Just a quick bit of feedback, I find the pop-out Ninja at the bottom right of the pages at https://docs.telerik.com/ that ask if the content was useful quite distracting.

If I'm trying to read a complicated help topic it's distracting to have the Ninja constantly popping out like that.

Could you set a cookie that remembers if the user has chosen to hide the Ninja, to never pop it out again?

Thanks

The code we use is

manager.ActiveBrowser.Cookies.SetCookie(cookie);

But when we getcookie, we found nothing.

Thanks very much.

Hi,

We're evaluating Telerik frameworks. The functionality seems good, but we need more control over the theme. The Theme Builder has limited color options, and no padding/spacing options. Looking into the CSS file, it's a massive 38,000+ lines of CSS.

Are there any more advanced theme editing tools or doc/guides on how the styles are constructed and organized?

Thanks,

Brett

Hi Team,

We are migrating Internet Explorer to Edge in Telerik C# framework.

We are changing BrowserType.InternetExplorer to BrowserType.MicrosoftEdge. But we are getting error like

Message: 
Microsoft WebDriver is not installed! You can download it from here: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/.

  Stack Trace: 
ArtOfTest.WebAii.BrowserSpecialized.MicrosoftEdge.WebDriverException: Microsoft WebDriver is not installed! You can download it from here: https://developer.microsoft.com/en-us/microsoft-edge/tools/webdriver/.
EdgeActions.LaunchNewBrowserInstance(ProcessWindowStyle windowStyle, Manager manager).

But we are able to launch browser using EdgeChromiium and Chrome.

For EdgeChromium and Chrome, works only on adding Progress Telerik Test Studio Extension.

Is there any ways to avoid adding extension from chrome store. and Edge browser works like IE?

Kindly suggest?
