I have a webpage built on Telerik controls. I am trying to show the page in the winforms application using web browser.

I face few issues when loading the page for first time.

RadTreeview is visible with the Parent Node details and they are visible like unordered list instead of + symbol. No action could be performed.

When i do a refresh on the screen i was able to perform the actions (expand,select,etc). I am facing this issue only with the first load of the webpage in web browser.

Could you please help me on how to solve this issue?

Regards,

Supriya.

Hello Supriya,

Could you clarify which product do you use in your web page? You mention RadTreeView, however, the helper that is included in the UI for ASP.NET Core product is called TreeView. RadTreeView is a control we offer in other products, for example UI for ASP.NET AJAX, UI for WinForms, etc.

As for the issues with the WebBrowser control, it by default renders the pages using older IE modes, which could explain the exhibited unexpected behavior. We would suggest you to try out embedding Chrome browser in the WinForms application: see this Knowledge Base article for more details.
