Hi,

I'm new to Rad Controls, can any one please help me to resolve this issue

I have one RadGrid, in this I placed one gridtemplatecolumn which contains one panel. This panel contains two buttons and one label. I'm using this panel as popup.

My problem is when i click on fist button(Delete) the row should delete and when I click on link(Cancel) the panel should hide.
I'm not getting how to access this button and link in code behind.

this is my code..

<Code>
<telerik:GridTemplateColumn UniqueName="DeletePopup">
                                        <ItemTemplate>
                                            <asp:LinkButton ID="PopupImgButton" CssClass="useredit" Text="Delete"
                                                runat="server" OnClientClick="this.disabled=true;__doPostBack(this.name,'');return false;" />
                                            <asp:Panel ID="PopUpPanel" runat="server" BackColor="White" BorderColor="Red" BorderStyle="Solid"
                                                BorderWidth="1px" Width="809px" Height="25px" CssClass="edit">
                                                <div>
                                                <asp:Button ID="Button1" runat="server" Text="Delete" CommandName="Deletebtn" OnClientClick="this.disabled=true;__doPostBack(this.name,'');" />
                                                    <asp:Label ID="Label1" runat="server" Text="Are you sure you want to delete [John Smithfield]? This cannot by undone."></asp:Label>
                                                    <a href="#" class="NormalCloseLink" style="padding-left:300px;color:Blue">CANCEL</a>
                                                </div>
                                            </asp:Panel>
                                            <asp:PopupControlExtender ID="ImgPopupControlExtender" runat="server" TargetControlID="PopupImgButton"
                                                PopupControlID="PopUpPanel" Position="Top" OffsetX="-745" OffsetY="7">
                                            </asp:PopupControlExtender>
                                        </ItemTemplate>

Hi,

please see below link and let me know if any concern.

.aspx page code
<telerik:GridTemplateColumn UniqueName="DeletePopup">
   <ItemTemplate>
       <asp:LinkButton ID="LnkOpenPopup" runat="server" CommandName="OpenPopup" onclick="lnkOpenPopup_Click">
       <ajax:ModalPopupExtender ID="mp1">
       <asp:Panel>
           <asp:Button ID="btnDelete" onclick="btnDelete_Click">
           <asp:Button ID="btnClose" onclick="btnClose_Click">
       </asp:Panel>
   </ItemTemplate>
</telerik:GridTemplateColumn>

.aspx.cs page code

lnkOpenPopup_Click()
{
   LinkButton LnkOpenPopup = (LinkButton)sender;
           GridDataItem item = (GridDataItem)LnkOpenPopup.NamingContainer;
           ModalPopupExtender mp1= (ModalPopupExtender)item.FindControl("mp1");
           mp1.Show()
}

btnDelete_Click()
{
   Button btnDelete= (Button)sender;
           GridDataItem item = (GridDataItem)btnDelete.NamingContainer;
           ModalPopupExtender mp1= (ModalPopupExtender)item.FindControl("mp1");
           mp1.Hide();
   // string ID = item.GetDataKeyValue("ID").ToString(); // get data key value for delete
}

btnClose_Click()
{
   Button btnClose= (Button)sender;
           GridDataItem item = (GridDataItem)btnClose.NamingContainer;
           ModalPopupExtender mp1= (ModalPopupExtender)item.FindControl("mp1");
           mp1.Hide();
}

Thanks,
