---> How to fix this issue ?

How does resolve this issue?
Thanks.

Could you give me a recording sample with Radcombobox ?

Hi Totti,

There was a bug in our wrappers which we introduced with the version you are using. It is already fixed. You can download the latest internal build from here: http://www.telerik.com/downloads/nightbuildfiles/bacg/Telerik.WebUI.TestStudio.Dev.2010.3.1307.msi. The fix is included in it.

We are sorry for the inconvenience caused. If you are still having problems please let us know.

All the best,
Boyan

I'm having the same issue with R2 release. I attempted to access your link above, but the page is no longer valid.

Hello Lora,

Use this link to download the latest version of Test Studio. If your issue persists after upgrading, please provide more information on it.

I am also facing the same issue of timeout. I am using free Telerik Testing framework with MSTest. If, I call the selectItem method directly from the Test method, It is working fine. But If I create a reusable method and call it from Test method. It is giving timeout exception. Ex. 

[TestMethod]

public void SelectItem(){

element.SelectItem(10, true);

}

The above code is working fine. but not below one

TestMethod]
public void SelectItem(){
SelectItemByIndex(10);
}

public static SelectItemByIndex(int index){

element.SelectItem(index, true);

}
