CheckBoxes not rendering in Excel-Like filtering

[Marcus]

Hi All,

I copied the demo code for Excel-Like filtering (here) into one of my projects, but the checkboxes in the filterlist are not rendering. However, they do render in the demo app on the Telerik website.

Possible bug in my version of the controls? I'm on 2019.3.1023.45.

Thx in advance - M.

Hello Marcus,

The online demos are using also the same version 2019.3.1023, so the issue should not be due to a version issue.

Can you please verify that the same behavior is observed in all browsers? 

Also, you can ensure that all controls are rendered with the same render mode, for example, you can set the default render mode to Lightweight in the web.config:

• https://docs.telerik.com/devtools/aspnet-ajax/controls/render-modes#setting-render-mode;
• https://www.telerik.com/support/kb/aspnet-ajax/details/determine-the-render-mode-of-all-telerik-controls-and-catch-mixed-render-mode-issues

<appSettings>
    <add key="Telerik.Web.UI.RenderMode" value="lightweight" />
</appSettings>

If the issue persists, please check the browser console and the Network tab for any JavaScript errors or any failing requests:

• https://www.telerik.com/blogs/improve-your-debugging-skills-with-chrome-devtools#inspect-network-requests;

Also, if you are using a form decorator on the page, can you please remove it and see if the issue persists.

Found it.

the page template I'm using for some reason had this CSS rule: input { -webkit-appearance: none;}
After commenting this out, everything is rendering correctly.

Thx again.
