Grid view and delete button

Hello,
I am trying to use gridview instead of listview.

Code:

<ItemTemplate>
<li>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("ImageUrl") %>' ToolTip='<%# Eval("ToolTip") %>' />
<asp:Label ID="DescriptionLabel" runat="server" Text='<%# Eval("Description") %>' />&nbsp;
<asp:Button ID="DeleteButton" CommandName="Delete" runat="server" Text="Delete" /><br /><br />
</li>
</ItemTemplate>

As in the listview delete button is accessible through its ID "DeleteButton" like this

Code:

Dim deleteButton As Button = CType(e.Item.FindControl("DeleteButton"), Button)

Here I wanna use grid view and delete button for this I have used the commandField Delete in grid view but I can not access it as it does not provide any ID attribute.

Code:

<asp:CommandField ShowDeleteButton="true" />

So how I can access this delete button in grid view like this

Code:

Protected Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowCreated
        Select Case e.Row.RowType
            Case DataControlRowType.DataRow
                Dim deleteButton As Button = CType(e.Row.FindControl("DeleteButton"), Button)
                deleteButton.Visible = Roles.IsUserInRole("Manager")
        End Select
    End Sub

Thank you.

Hi there,

On the Edit Fields / Columns dialog of the GridView you can tranform the column into a template column which then gives you access to the button.

Since this isn't directly related to the book, can you ask these kind of questions in a more general ASP.NET category here: http://p2p.wrox.com/asp-net-3-5-436/

Cheers,
