[Solved] RadGrid - Web User Control Postbacks

[Atlas]

Hello all,

I have a radgrid with an edit form type of web user control. My user control has two combo boxes and a listbox. These combo box selections filter the items within the listbox. I have a RadAjaxManagerProxy within the user control as follows:

<telerik:RadAjaxManagerProxy ID="ctrlAjaxManager" runat="server">
        <AjaxSettings>
            <telerik:AjaxSetting AjaxControlID="cbLocations">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="lbAvailableEmployees" />
                </UpdatedControls>
            </telerik:AjaxSetting>
            <telerik:AjaxSetting AjaxControlID="cbOccupations">
                <UpdatedControls>
                    <telerik:AjaxUpdatedControl ControlID="lbAvailableEmployees" />
                </UpdatedControls>
            </telerik:AjaxSetting>
        </AjaxSettings>
</telerik:RadAjaxManagerProxy>

These postbacks (selecting different combo box items; OnItemChecked) are causing the parent Grid (which resides in the web form) to refresh and fire the Grid's events: ItemCreated and PreRender. Is there any way to avoid having this occur, as it negatively affects performance in a significant way. Any help is greatly appreciated

Hi Dean,

If I correctly understand your scenario the UserControl, you have provided markup is used as edit form for a RadGrid control. If this is the case the presented behavior is expected. In case update is performed in the UserControl the whole RadGrid control will also update and this could not be avoid.

All the best,
