Hi there..

Based on a value from my SQLQuery i'm trying to display an image instead of the value in my DataGrid.
The special thing is that i cannot display the value itself inside the grid (due to securityreasons), but i need to use this value to loop through and decide which image (on or off image) should be displayed.

If i hard-code the imageURL like this :
ImageUrl="img\offline24.gif"      it works like a dream..

But.. when i do like this :

ImageUrl='img\<%#Bind("Image") %>'       the image doesn't display, and when looking at properties on the image it shows the <%# Bind("Image") %> as pure text..

So what am i doing wrong here ? or.. how can i do this another way ?



See the code :


--------------The TemplateColumn------------------

<asp:TemplateColumn ItemStyle-Width="40px">
        <ItemTemplate>
        <asp:Image ID="Image2" runat="server" ImageUrl='img\<%#Bind("Image") %>'></asp:Image>
        </ItemTemplate>
</asp:TemplateColumn>

--------------The TemplateColumn------------------


--------------The Code to generate the Item column and choose image------------------

        Dim ds As New DataSet
        myAdapter.Fill(ds)

        Dim c As New DataColumn
        c.ColumnName = "Image"

        ds.Tables(0).Columns.Add(c)

        Dim r As DataRow

        For Each r In ds.Tables(0).Rows
            If r.Item(2) = "1" Then
                r.Item(4) = "Online24.gif"
            Else
                r.Item(4) = "Offline24.gif"
            End If

        Next

        Dim dt As DataTable = ds.Tables(0)

        'return a DataView to the DataTable
        Dim dv As DataView = New DataView(dt)
        dv.Sort = SortField
        Ansatt_Update = dv

        con.Close()

More info :

It's .NET 1.x Framework.


and when using this scentence :

<asp:Image ID="Image2" runat="server" ImageUrl='<%# String.Concat("img\", Bind("Image")) %>'></asp:Image>

I'm getting "Bind is not declared"    (same goes with Eval)...

Try this:

DataBinder.Eval(Container.DataItem, "Image")
