Hi,

I suspect that the events are not raised by the fact that you are rebinding the grid control on every postback. Please refer to our help documentation for more information on various ways to databind RadGrid (under Controls->RadGrid->Populating the control with data)

Hi,

If you are updating your grid manually then you would have to set the AllowAutomaticUpdates property of the grid to false. Also the ItemUpdated event of the grid is meaningful only when you use automatic data editing operations via a DataSource control. Hence, if you prefer to manually update your grid items to the db you can review the following online demo(along with the help article linked under the Description tab):
Manual Update/Insert/Delete

Thanks
Princy.

Well, nothing worked for me. i used the AllowAutomaticUpdates = false and OnNeedDataSource like

the examples .... still the event not firing ...

        protected void RadGrid1_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

        {

            // Get Node Servers.

            BTServerNodeFactory nodeFactory = new BTServerNodeFactory(ConnectionString);

            BTServerNode[] nodes = nodeFactory.GetNodesByCompany(AdminUser.CompanyID);

            RadGrid1.DataSource = nodes;

        }

Hi,

The RadGrid doesn't support mixing of simple data-binding mode with advanced data-binding . Could you make sure that you are not implementing the Panel_Load event to bind the grid using DataBind along with the NeedDataSource event.You can call Rebind () in order  to rebind the grid on a postback

Thanks,
Shinu

Hi Shinu,

On a specific ascx i have RadGrid and on that RadGrid, i have one Update button on Grid Header. And i have 2 columns in grid. In first Column i have data and second column i have check box against perticular row. Now When i checked any check box in grid and click on Update button, the OnUpdateCommand not firing. I saw lot of question regarding this on forum as well as i followed the following link that you have suggested (http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/extractvalues/defaultcs.aspx)  but didn't get success.I have follwoing Grid

<telerik:RadGrid ID="RadGrid1" runat="server" GridLines="None" OnUpdateCommand="RadGrid1_UpdateCommand" OnNeedDataSource="RadGrid1_NeedDataSource"

        EnableViewState="true" ClientIDMode="AutoID">

            <MasterTableView AutoGenerateColumns="False" EditMode="InPlace" CommandItemDisplay="Top"

                PageSize="10">

                <ExpandCollapseColumn>

                    <HeaderStyle Width="20px"></HeaderStyle>

                </ExpandCollapseColumn>

                <CommandItemTemplate>

                    <div style="float: right; font-size: medium;">

                        <asp:Button ID="BtnCommand1" Text="Update" runat="server" CommandName="Update" CssClass="button">

                        </asp:Button>

                    </div>

                </CommandItemTemplate>

                <Columns>

                    <telerik:GridTemplateColumn HeaderText="Flag" UniqueName="ABC" SortExpression="ABC">

                        <HeaderTemplate>

                            Access Flag

                            <asp:CheckBox ID="chkSelectAll" runat="server" OnCheckedChanged="chkSelectAll_CheckedChanged"

                                AutoPostBack="true" ToolTip="Select All" />

                        </HeaderTemplate>

                        <ItemTemplate>

                            <asp:CheckBox ID="chkboxaccess1" runat="server" Checked='<%#Convert.ToBoolean(Eval("Flag")) %>' />

                        </ItemTemplate>

                    </telerik:GridTemplateColumn>

                </Columns>

            </MasterTableView>

        </telerik:RadGrid>

Can you tell me Why the RadGrid update command not firing ? I have RadScript Manager on my Master page.
