    Hi, there is a performance issue with the RadComboBox when you fill it with many records in Crhome 33.
    I'm using 2013 Q3 SP2 Version.
    In IE and Firefox it is fine.

    Best regards.

    Hello,

    We are not aware of such problem with the RadComboBox control under Chrome 33. Could you please clarify how many items do you have in your RadComboBox? This way we can test pretty similar scenario and investigate this behavior.

    Yes there is definitely a performance issue.  This is a simple example but if you add longer text items the dropdown becomes unusable.  This is probably a Chrome 33 issue as it never happened with previous versions.

    <telerik:RadComboBox ID="combobox" AllowCustomText="true" MaxLength="255" runat="server"></telerik:RadComboBox>


    var items = new List<
    Tuple<int, string>>();
          
          for (int i=0; i < 2000; i++)
          {
            items.Add(new Tuple<int, string>(i, "aeewaufawuhfuhawuhfawuhfawhue"));
          }
     
          combobox.DataSource = items;
          combobox.DataBind();

    The RadComboBox freezes when you try to expand it...

    Hello,

    I would like to confirm that there is a problem with opening the RadComboBox drop down list under Google Chrome 33. I would like to assure you that we will investigate this problem. Since there was no issue with older versions of Google Chrome we will report this issue to Google. I would like to clarify that there is no problem with our RadDropDownList control. Please note that this is a very similar control and a valid control would be to use it instead of the RadComboBox.

    Hello,

    I would like to clarify that we have tested same RadComboBox scenario under Google Chrome 34 beta and it works fine. It seems that there was a browser bug that is fixed in the latest version.
