why rad grid is binding data two times?

[khaled jendi]

hi,
I have this rad grid:
                                                                <telerik:RadGrid ID="RadGrid1"
                        AllowSorting="True"
                        AllowPaging="True" PageSize="5" runat="server" GridLines="None" Width="95%"
                        OnItemCommand="RadGrid1_ItemCommand"
                        OnNeedDataSource="RadGrid1_NeedDataSource" Skin="Sunset">
                        <ExportSettings HideStructureColumns="true" />
                             <MasterTableView Width="100%" CommandItemDisplay="Top"   >


                             <Columns>
                                <telerik:GridBoundColumn DataField="SerialNum" />
                                <telerik:GridBoundColumn DataField="Name" HeaderText="Name"  />
                                <telerik:GridBoundColumn DataField="UserName" HeaderText="User Name" />
                                <telerik:GridBoundColumn DataField="Phone1" HeaderText="Phone-1-"  />
                                <telerik:GridBoundColumn DataField="Email" HeaderText="Email" />
                                <telerik:GridBoundColumn DataField="Phone2" HeaderText="Phone-2-" />
                                <telerik:GridBoundColumn DataField="ActiveState" HeaderText="Active State" />
                                <telerik:GridBoundColumn DataField="Fax" HeaderText="Fax" />
                                <telerik:GridTemplateColumn>
                                    <ItemTemplate>
                                            <asp:LinkButton ID="lnkbdeactive" runat="server" CommandArgument='<%# eval("User_ID") %>'
                                                CommandName="Deactive" CssClass='<%# ShowIfNotActive(Eval("Active"), "lnkbdeactive") %>'>De-activate</asp:LinkButton>
                                            <asp:LinkButton ID="lnkbactive" runat="server" CommandArgument='<%# eval("User_ID") %>'
                                                CommandName="Active" CssClass='<%# ShowIfNotActive(Eval("Active"), "lnkbactive") %>'>Activate</asp:LinkButton>
                                    </ItemTemplate>
                                </telerik:GridTemplateColumn>
                             </Columns>


                                <PagerStyle Mode="NextPrevNumericAndAdvanced" />
                                <CommandItemSettings ShowExportToWordButton="true" ShowExportToExcelButton="true" ShowExportToPdfButton="true" ShowAddNewRecordButton="false"
                                    ShowExportToCsvButton="true" ExportToCsvText='<%= "CSV_" & ExportSubFileName %>'    />
                            </MasterTableView>
                        </telerik:RadGrid>

I got the grid rendered two times, I can see the grid like this:

Hello Khaled,

Check the following forum thread which discussed similar scenario.
RadGrid's NeedDataSource Firing Another Postback?

Also check the following help documentation which explains more about event sequence and Commands that invoke Rebind() implicitly.
Event sequence.

Thanks,
Princy.
