Hello All -

 I am using a datalist to display XX rows as mini tables on a details page.

 I have another field being sent as part of the result set, (one that is not going to be displayed)

 Container.DataItem("Flagged")

I would like to be able to use this value in a comparisson test and if it evaluates to the specified value then change the background color of the current table being displayed.

For instance.

 My details query yields 3 rows in the result set.

 TotalGenerated : Subject : Message : Flagged

    10            15              23         0
   203            1           4          0
   100            32          23         1

 When displaying the results using the template below I would like to be able to do the following. ( I realize the code below would never work at all .. )

 If FLAGGED = 1 THEN
      Change the background color of the current Datalist Table to RED (or whatever)

 END IF


 Is this possible?

 If possible please try to make any examples in VB ( thanks in advance )

Use ItemDataBound event of the DataList ...

    Private Sub MyDataList_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataListItemEventArgs) Handles MyDataList.ItemDataBound
        If (e.Item.DataItem("FLAGGED") = 1) Then
            e.Item.BackColor = Color.Red
        End If
    End Sub
