DropDownList input flicker

[Aleks]

The input tag used by DropDownList is sometimes briefly visible on the page while JavaScript and CSS assets are loading.

If the input tag is meant to be hidden anyway, why aren't you writing the style attribute out with the HTML from the tag helper?

Instead it's being set by the associated scripts, which means the input is visible until the script has loaded and run.

Hello Aleks,

This behavior is know as flash of unstyled content (FOUC) and has been discussed in this forum thread: https://www.telerik.com/forums/how-to-fix-the-foucing-menu

You can try placing the component in an invisible container (e.g., a div) and show it on document.ready, or even later, for example once the DropDownList's dataBound event has fired.

With regard to our styles, we don't hide the input of the DropDownList initially, but you can do so by using the approach mentioned above.
