I'm using a telerik radcombobox inside an updatepanel which is inside a radpageview of radmultipage.
Hierarchy Example (not actual code):
<telerik:radmultipage>
<telerik:radpageview>
<asp:updatepanel>
<telerik:radcombobox><telerik:radcombobox>
</asp:updatepanel>
</telerik:radpageview>
</telerik:radmultipage>
From the rendered page, I am able to open up the combobox and see it's many entries. However, upon clicking on an entry to select it, then Chrome freezes (it gets slow)--usually for 30 seconds.
Yes, the serverside callback from event onselectedindexchanged is called very quickly, without delay. I haven't found serverside bottle necks. Thus, the problem appears to be in the browser. In fact, to confirm the browser is frozen, I execute some code in Chrome's console (via developer tools) and it doesn't execute until the browser unfreezes.
Using
- Chrome: Version 27.0.1453.116 m
- ASP.NET Forms
- Telerik.Web.UI.dll (2010.1.519.35)
Chrome's Dev Tools: Network Request speed is great except for Receiving
- Blocking 0ms
- Sending 1ms
- Waiting 54ms
- Receiving 29 s (HUGE JUMP)
Chrome's Dev Tools: Profile A great percentage of time is spent in:
- set innerHTML
- a.RadComboBox._onDropDownClick
- a.RadComboBox._hideDropDown
- a.RadComboBox._removeEmTagsFromAllItems
Any help would be greatly appreciated. :)
