Accessing GridView Control when it is in a RoleGroup Content Template.

Jun 29, 2012 08:50 PM|LINK

Hello,

I using role groups. I am trying to bind the gridview (in code behind) using:

accounteRequestsViewer.DataSource = datasource ;
accounteRequestsViewer.Databind();

At first I was getting an error: accountRequestsViewer does not exist in the current context. This seems to
be due to the fact that the accountRequestsViewer is in my asp:loginview.

So I in my code behind I added this line:

GridView accountRequestsViewer = (GridView)viewRequestsLoginView.FindControl("accountRequestsViewer");

But this is returning null??

How can I access the accountRequestViewer to do the databind?

 <asp:LoginView ID="viewRequestsLoginView" runat="server">
                            <RoleGroups>
                                <asp:RoleGroup Roles="Role1">
                                    <ContentTemplate>
                                        <asp:GridView ID="accountRequestsViewer" runat="server" AllowSorting="True" CellPadding="4"
                                            CellSpacing="1" CaptionAlign="Top" ForeColor="#333333" GridLines="Vertical" AutoGenerateColumns="False">
                                            <AlternatingRowStyle BackColor="White" />
                                            <Columns>
                                                <asp:BoundField DataField="requestType" HeaderText="Request Type" />
                                            </Columns>
                                        </asp:GridView>
                                    </ContentTemplate>
                                </asp:RoleGroup>
                                <asp:RoleGroup Roles="RoleB">
                                    <ContentTemplate>
                                        <asp:GridView ID="accountRequestsViewer" runat="server" AllowSorting="True" CellPadding="4"
                                            CellSpacing="1" CaptionAlign="Top" ForeColor="#333333" GridLines="Vertical" AutoGenerateColumns="False">
                                            <AlternatingRowStyle BackColor="White" />
                                            <Columns>
                                                <asp:BoundField DataField="requestType" HeaderText="Request Type" />
                                                <asp:BoundField DataField="requestName" HeaderText="for:" />
                                            </Columns>
                                       </asp:GridView>
                                    </ContentTemplate>
                                </asp:RoleGroup>
                            </RoleGroups>
                         </asp:LoginView>

there are two grid with same name. Is it possible for you to use different names? If not put panel with different Ids and find the panel control first and then find the grid from that control again

Hi wtholmes,

Thank you for posting.

According to your description, it seems like that you want to bind the gridview in the loginview. As far as I know, when we want to find the control in the loginview control, you need to use findcontrol method and make sure that the control is in the active template. You can't access the control in the no-active template. Thus, if you want to find the "accountRequestsViewer" in the Role1, please make sure that Role1 is in active state at first. Then use findcontrol to find the GridView . Please check the similar threads below:

In addition, if it doesn't resolve your issue, please debug your code an find whether the viewRequestsLoginView is null.
