Question

Edit – Thanks for your replies so far and sorry for not stating exactly what the problem was. The actual markup code is

<asp:DetailsView ID="dvwSomeDetailsView" runat="server" 
  AutoGenerateRows="False" DataSourceID="SomeDataSourceID">
  <Fields>
    <asp:TemplateField HeaderText="SomeText" SortExpression="SomeText">
      <EditItemTemplate>
        <cc1:Editor ID="txtDescription" runat="server" 
          Content='<%# Bind("SomeText") %>' />
      </EditItemTemplate>
      <ItemTemplate>
        <asp:Label ID="lblDescription" runat="server" 
          Text='<%# Bind"SomeText") %>'></asp:Label>
      </ItemTemplate>
    </asp:TemplateField>

    <asp:CommandField ButtonType="Image" CancelImageUrl="~/img/cancel.png" 
      EditImageUrl="~/img/edit.png" InsertImageUrl="~/img/insert.png"
      UpdateImageUrl="~/img/save.png" ShowEditButton="True" />
</asp:DetailsView>

I’m not too sure whether setting the ShowEditButton property should be removed, but when I tried to do that I still couldn’t set it programmatically.

Now in the code behind file I reduced the Page_Load method to this

protected void Page_Load( object sender, EventArgs e )
{
  dvwSomeDetailsView.AutoGenerateEditButton = true;
}

What I want to achieve is that by changing the assignment in the Page_Load method I can hide / show the Edit button, but that does not work. When playing around in the markup file I can make the button show up or hide, but I can never change it from the code behind file.

I also tried to explicitly call dvwSomeDetailsView.DataBind after setting the property, but this also didn’t work. Overriding OnPreRender and placing the code from the Page_Load method in their didn’t do anything to improve this either.

Maybe I’m thinking too complicated – shouldn’t there be an easy way to set programmatically whether the button should / shouldn’t show?

Thanks in advance for any comments.

Answer 1

If the code redacted behind the

[... Some Stuff...]

contains a call to detailsView.DataBind() (either directly or through Page.DataBind()), then that is your problem. The AutoGenerateEditButton property must be set prior to calling DataBind on the DetailsView.
