How can I make linkbutton visible in Gridview?

Question

The OnClick="lnkRelease_Click" does not change the boolean values for my linkbutton controls in the itemtemplate.

Any help on pointing me to the right direction, would be appreciated.

My ASP page:

 <asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="Id,InsertDate" DataSourceID="HRD" ShowFooter="True" HorizontalAlign="Center">  
        <Columns>  
            <asp:TemplateField ShowHeader="False">  
                <FooterTemplate>  
                    <asp:LinkButton ID="lnkInsert" runat="server" CssClass="button" OnClick="lnkInsert_Click" ValidationGroup="Insert">Add</asp:LinkButton>  
                    <asp:LinkButton ID="LnkDeduct" runat="server" OnClick="LnkDeduct_Click" ValidationGroup="Insert">Deduct</asp:LinkButton>  
                </FooterTemplate>  
                <ItemTemplate>  
                    <asp:LinkButton ID="lnkRelease" runat="server" Visible="true" Text="Release" OnClick="lnkRelease_Click"></asp:LinkButton>  
                    <asp:LinkButton ID="lnkLock" runat="server" Visible="false" Text="Lock"></asp:LinkButton>&nbsp;  
                    <asp:LinkButton ID="lnkDel" runat="server" Visible="false"  
                        CommandName="Delete" OnClientClick="return confirm('Are you sure you want to Delete?');" Text="Delete" OnClick="lnkDel_Click"></asp:LinkButton>  
                </ItemTemplate>  
                <ItemStyle Width="100px" Wrap="False" />  
            </asp:TemplateField>  

And my code page for the OnClick event:

        protected void lnkRelease_Click(object sender, EventArgs e)  
        {  
          
            foreach (GridViewRow row in GridView1.Rows)  
            {  
                ((LinkButton)row.FindControl("lnkLock")).Visible = true;  
                ((LinkButton)row.FindControl("lnkDel")).Visible = true;  
                ((LinkButton)row.FindControl("lnkRelease")).Visible = false;  
            }  
  
        }  

Answer 1

The standard GridView pattern is link buttons are associated with a Gridview template; Item template, Edit template, etc. Toggling the GridView templates shows the associated link button(s) for that template. I recommend going through the following tutorial.

Thanks,

I had figured it out to use the RowCommand instead:

        protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)  
        {  
            GridViewRow row = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);  
  
            if (e.CommandName == "Release")  
            {  
                ((LinkButton)row.FindControl("lnkLock")).Visible = true;  
                ((LinkButton)row.FindControl("lnkDel")).Visible = true;  
                ((LinkButton)row.FindControl("lnkRelease")).Visible = false;  
            }  
            else   
            {  
                ((LinkButton)row.FindControl("lnkLock")).Visible = false;  
                ((LinkButton)row.FindControl("lnkDel")).Visible = false;  
                ((LinkButton)row.FindControl("lnkRelease")).Visible = true;  
            }  
        }
