I have a RadGrid with filtering enabled.  The one column uses CheckList filtering.  In IE11 everything works perfectly, except in Chrome and Edge.

In Chrome and Edge, the checklist item displays as normal list items, see attached images.

I've upgraded to v2020.1.219.45 to see if it would resolve the issue, but no luck.  I'm using .NET Framework 4.6.2.

This is working on another solutions, I've compared the code and it is exactly the same.

I would appreciate any leads.

Thanks in advance.

Hi Fanie,

There is nothing specific in the checkboxes used by the RadComboBox control which may hide them in Chrome and Edge.

Can you please perform the following test to check whether the problem persists if you set the RenderMode property to Classic?

Another thing is to right-click over the line where we expect the checkbox to be placed and choose Inspect from the context menu of the browser. After that see whether the input of type="checkbox" gets created and is available in the generated markup. 

If it is there, see the applied CSS styles over it and look for -webkit-appearance: none; which purpose is to hide the checkbox elements in chrome.

You can also try to show the checkbox via this CSS class:

input[type=checkbox]
{
  -webkit-appearance:checkbox;
}

as explained at SO Checkboxes not displaying Chrome - Work in other browsers.

You may also set EnableAjax="false" to the RadAjaxPanel and see whether the AJAX is somehow related to the problem.

Best Regards,
Rumen

Hi Rumen,

I can confirm that adding CSS class resolved the problem.  I had a class that sets the appearance to none.

button,
input {
  -webkit-appearance: none;
  cursor: pointer;
}
 
input[type=checkbox] {
        -webkit-appearance:checkbox;
}

 

Thanks for your assistance.

Regards

Fanie
