Sorting question

[David]

For some reason my grid exhibits strange behavior. On first sort grid sorts as expected, but on second it just shows busy sign.

My source is following:

On Load:

    Session("grdPorts") = dtAlternatePorts

OnNeedDataSource

    grdPorts.DataSource = Session("grdPorts")

And html:

 <telerik:RadGrid ID="grdPorts" runat="server" style="margin-top:23px; margin-left:10px;margin-right:5px;"
                                        Width="440px" skin="WebBlue"
                                        ShowFooter="false"
                                        AllowSorting="true"
                                        OnNeedDataSource="OnNeedDataSource">      
                                <ClientSettings Scrolling-AllowScroll ="true" Scrolling-ScrollHeight="705px" />                    
                                <MasterTableView GroupLoadMode="Client" AutoGenerateColumns="False" HeaderStyle-Font-Bold="true">
                                    <HeaderStyle BackColor="#6D8DAD" ForeColor="White"/>
                                    <ItemStyle CssClass="InnerItemStyle"/>
                                    <AlternatingItemStyle CssClass="InnerAlernatingItemStyle" BackColor="#E3E1E1"/>                                  

                                    <Columns>

                                    <telerik:GridBoundColumn DataField="WiserPortDesc" HeaderText="Port" HeaderStyle-HorizontalAlign="Center"  
                                                                ItemStyle-Width="280px" ItemStyle-HorizontalAlign="left"/>

                                    <telerik:GridBoundColumn DataField="curval" HeaderText="Value<br/>($M)" HeaderStyle-HorizontalAlign="Center"
                                                             SortExpression="curval"
                                                             ItemStyle-HorizontalAlign="Right"
                                                             ItemStyle-Width="80px" ItemStyle-CssClass="label_SS_8" DataFormatString="{0:N3}"/>                                      

                                    <telerik:GridBoundColumn DataField="Tons" HeaderText="Volume<br/>(ktons)" HeaderStyle-HorizontalAlign="Center"
                                                             SortExpression="Tons" ItemStyle-HorizontalAlign="Right"
                                                             ItemStyle-Width="80px" ItemStyle-CssClass="label_SS_8" DataFormatString="{0:N3}"/>

                                    
                                </Columns>

                                <NoRecordsTemplate>
                                    <div style="padding: 5px">
                                        No records available.
                                    </div>
                                </NoRecordsTemplate>

                            </MasterTableView>

                         </telerik:RadGrid>

Hi Eyup,

   The link didn't exactly helped.

   Essentially my problem exists when i have 

               <telerik:AjaxSetting AjaxControlID="grdPorts">
                    <UpdatedControls>
                        <telerik:AjaxUpdatedControl ControlID="grdPorts" LoadingPanelID="RadAjaxLoadingPanel1"/>
                    </UpdatedControls>
                </telerik:AjaxSetting>

     If i remove that, sort works fine, but other controls on the page flicker

     Does it help to pinpoint solution?

Hi David,

The provided RadAjaxManager settings look proper and,m unfortunately, cannot lead us to the cause of the problem. Can you verify that there is no other UpdatePanel wrapping the Grid?

Can you, please, follow the steps the following blog post and send us a runnable sample where we can reproduce the issue and examine the problematic configuration leading to it?
