[Kavya]

Hi
I am trying to delete the Complete group from Radgrid.Below is the code i am trying to use

<rad:RadGrid ID="Subsec_grid" Visible="False" Font-Size="X-Large" OnNeedDataSource="Subsec_grid_NeedDataSource" runat="server" EnableAJAX="True" EnableAJAXLoadingTemplate="True"  Skin="WebBlue"  GridLines="None" Width="335px" >
       <MasterTableView AutoGenerateColumns="False" Width="100%" DataKeyNames="Message,id"  >


       <Columns>
      <rad:GridBoundColumn UniqueName="name" SortExpression="name" ItemStyle-Font-Size="Medium" Groupable="False"  HeaderText="name" DataField="name" >
                    </rad:GridBoundColumn>

                    <rad:GridBoundColumn DataField="Message" ItemStyle-Font-Size="Medium" Groupable="False"  UniqueName="Message"  SortExpression="Message"  HeaderText="Message" >
                    </rad:GridBoundColumn>
                        <rad:GridTemplateColumn UniqueName="delete" AllowFiltering="False"   >
                    <ItemTemplate>
                    <asp:button  ID="del_lnk" runat="server" Text="Inactivate" OnClick="Delete_Section"  />

                    </ItemTemplate>
                        <ItemStyle HorizontalAlign="Left" />
                    </rad:GridTemplateColumn>

<rad:GridBoundColumn DataField="id" UniqueName="id" Visible="false"></rad:GridBoundColumn>


       </Columns>

        <GroupByExpressions >


                                                <rad:GridGroupByExpression >

                                                    <SelectFields >
                                                        <rad:GridGroupByField  FieldAlias="no" FieldName="no" HeaderText="Number" />

                                                    </SelectFields>
                                                    <GroupByFields>

                                                        <rad:GridGroupByField FieldAlias="no" FieldName="no"  HeaderText="Number"  />
                                                    </GroupByFields>
                                                </rad:GridGroupByExpression>
                                            </GroupByExpressions>

           <RowIndicatorColumn Visible="False">
               <HeaderStyle Width="20px" />
           </RowIndicatorColumn>
           <ExpandCollapseColumn Resizable="False" Visible="False">
               <HeaderStyle Width="20px" />
           </ExpandCollapseColumn>

       </MasterTableView>
       <ClientSettings EnablePostBackOnRowClick="true"></ClientSettings>
       </rad:RadGrid>

When view this i see inactivate button for each and every row.Is there a way i can show that button only for Groupfield which is bside Number.

I know ican use detailtable/ParentTableRelation is there any other simple way i can just add delete button to Groupfield

Thanks

Hello Kavya,

You can try out the following code to achieve the required scenario
cs:

 protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridGroupHeaderItem)
        {
            GridGroupHeaderItem groupHeader = (GridGroupHeaderItem)e.Item;
            string strtxt = groupHeader.DataCell.Text;
            Button btn = new Button();
            btn.ID = "del_lnk";
            btn.Text = "Inactivate";
            btn.Click += new EventHandler(btn_Click);
            Label lbl = new Label();
            lbl.ID = "Label";

            Table table = new Table();
            TableRow row = new TableRow();
            table.Rows.Add(row);
            TableCell cell1 = new TableCell();
            cell1.Controls.Add(btn);
            TableCell cell2 = new TableCell();
            cell2.Controls.Add(lbl);
            table.Rows[0].Cells.Add(cell1);
            table.Rows[0].Cells.Add(cell2);

            groupHeader.DataCell.Controls.Add(table);
        }
   }

  void btn_Click(object sender, EventArgs e)
    {
        Button btn = (Button)sender;
        GridGroupHeaderItem grpHeader = (GridGroupHeaderItem)btn.NamingContainer;
        GridItem[] children = grpHeader.GetChildItems();// to access the child items for the group
        //delete query
        RadGrid1.Rebind();
    }

 protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
       if(e.Item is GridGroupHeaderItem)
        {
            GridGroupHeaderItem groupHeader = (GridGroupHeaderItem)e.Item;
            string strtxt = groupHeader.DataCell.Text;
            Button btn = new Button();
            btn.ID = "del_lnk";
            btn.Text = "Inactivate";
            Label lbl = new Label();
            lbl.ID = "Label";
            if (strtxt != " ")
                lbl.Text = strtxt;

            Table table = new Table();
            TableRow row = new TableRow();
            table.Rows.Add(row);
            TableCell cell1 = new TableCell();
            cell1.Controls.Add(btn);
            TableCell cell2 = new TableCell();
            cell1.Controls.Add(lbl);
            table.Rows[0].Cells.Add(cell1);
            table.Rows[0].Cells.Add(cell2);

            groupHeader.DataCell.Controls.Add(table);
        }
    }

Thanks
