Hi,

i have a gridview that has only one column but multiple rows that i converted into a template column.

I have a linkbutton in this column that when clicked should collect the rows primary data key (forumId) and then insert it into a querystring and redirect to the threads page.

How do i select a datakey in the code behind file for the selected row without using the Selectedindexchanged event handler?

<asp:TemplateField HeaderText="Title" SortExpression="Title">
                        <EditItemTemplate>
                            <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Title") %>'></asp:TextBox>
                        </EditItemTemplate>
                        <ItemTemplate>
                            <asp:LinkButton ID="lnkForumName" runat="server" Text='<%# Bind("Title") %>' 
                                CommandName="Select" onclick="lnkForumName_Click"></asp:LinkButton>
                            <br />
                            <asp:Label ID="lblForumDescription" runat="server" 
                                Text='<%# Eval("Description") %>' CssClass="Forum_Description"></asp:Label>
                        </ItemTemplate>
                    </asp:TemplateField>

<asp:TemplateField HeaderText="Title" SortExpression="Title">

                        <EditItemTemplate>

                            <asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("Title") %>'></asp:TextBox>

                        </EditItemTemplate>

                        <ItemTemplate>

                            <asp:LinkButton ID="lnkForumName" runat="server" Text='<%# Bind("Title") %>' 

                                                          onclick="lnkForumName_Click"></asp:LinkButton>

                            <br />

                            <asp:Label ID="lblForumDescription" runat="server" 

                                Text='<%# Eval("Description") %>' CssClass="Forum_Description"></asp:Label>

                        </ItemTemplate>

                    </asp:TemplateField>

To get the DataKey, I use the ItemCommand Event in the DataGrid like so:

Protected Sub dgName_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles dgName.ItemCommand
        If e.CommandName = "Item" Then
                Dim myParm = dgName.DataKeys(e.Item.ItemIndex)
        End If
End Sub

Let me know if this help
