How to update image control in grid cell

[Tomica]

I have an ASP.NET image control in a templated column within RadGrid (lastest release)

I have been able to adjust the background color of the cell as shown in the code below. However, the client prefers that I use customized icons that would vary based on several data conditions.

I am hoping there is a way that I can access the ImageUrl property of the control in this cell.
 
Note that this control differs from my color-coding example quoted below, but I think that whatever statement I need would fit into that overall logic.

 

<telerik:GridTemplateColumn DataField="id"
    FilterControlAltText="Filter column column" HeaderText="Info"
    UniqueName="ID_column" SortExpression="id">
    <ItemTemplate>
           <asp:Image ID="targetControl" runat="server" ImageUrl="images/info16.gif" />
    </ItemTemplate>

Protected Sub Event_Grid_ItemCreated(sender As Object, e As Telerik.Web.UI.GridItemEventArgs) Handles Event_Grid.ItemCreated

    Dim Temp As String = Nothing

    Dim Event_Date As Date = Nothing

    Dim End_Date As Date = Nothing

    If TypeOf (e.Item) Is GridDataItem Then

        Try

            Event_Date = CDate(e.Item.DataItem("event_date_sort"))

            End_Date = CDate(e.Item.DataItem("end_date"))

            Dim gdi As GridDataItem = CType(e.Item, GridDataItem)

            If End_Date < Today Then

                gdi.Cells(2).BackColor = System.Drawing.Color.Silver

            ElseIf (End_Date >= Today) And (Event_Date <= Today) Then

                gdi.Cells(2).BackColor = System.Drawing.Color.PaleGreen

            ElseIf Event_Date < DateAdd(DateInterval.Month, 1, Today) Then

                gdi.Cells(2).BackColor = System.Drawing.Color.Yellow

            Else

                gdi.Cells(2).BackColor = System.Drawing.Color.WhiteSmoke   

            End If

            If e.Item.DataItem("type_code") = "x" Then

                gdi.Cells(2).BackColor = System.Drawing.Color.Tomato

            End If

        Catch ex As Exception

            'leave default shading

        End Try

    End If

End Sub

Hi Tomica,

Try the following code snippet to access the ImageUrl property of the asp:Image.

VB:

Protected Sub Radgrid1_ItemCreated(sender As Object, e As GridItemEventArgs)
    If TypeOf e.Item Is GridDataItem Then
        Dim ditem As GridDataItem = DirectCast(e.Item, GridDataItem)
        Dim img As Image = DirectCast(ditem.FindControl("targetControl"), Image)
        img.ImageUrl = "your url"
    End If
End Sub

Thanks,
Shinu.

Thank you very much.

I have a general idea of what this code is doing and it works as given, except that I had to qualify "image" as "webcontrols.image" to resolve ambiguity.
