RadioButtonList 1 Row Coloured

Question

Please Help.

I am using ASP/ VB.net and I have a radio button populated from the database in the code behind like this.

rdoTheTest.DataSource = Test.Test_Get()
rdoTheTest.DataBind()

I now get the radio list on the screen and I want to colour 1 row, when I use this they all go the same colour.

rdoTheTest.ForeColor = Drawing.Color.Red

In the past when using a listview scenario I could do something like this;

Private Sub LvTheTest_ItemDataBound(sender As Object, e As ListViewItemEventArgs) Handles lvTheTest.ItemDataBound
    Dim SomeTextBox As TextBox = DirectCast(e.Item.FindControl("SomeTextBox"), TextBox)
    If DataBinder.Eval(e.Item.DataItem, "SomeDBVAR") = 1 Then SomeTextBox.ForeColor = Drawing.Color.Red
End Sub

My Intention was to do this;

Private Sub rdoTheTest_DataBinding(sender As Object, e As EventArgs) Handles rdoTheTest.DataBinding
    If DataBinder.Eval(e.Item.DataItem, "SomeDBVAR") = 1 Then sender.ForeColor = Drawing.Color.Red
End Sub

Problem is only 1 row is retrieved in DataBinding when there is 10 rows and when using ListView I get 10 rows because you can use Handles ItemDataBound you can manipulate on every row pull.

Any ideas.

You can always color the specific radio after the data have been bound using OnDataBound, for example:

Protected Sub rdoTheTest_DataBound(sender As Object, e As EventArgs)
    rdoTheTest.Items.FindByValue("SomeDBVar").Attributes.Add("style", "color: red")
End Sub

UPDATE:

Iterate bound list items and set the appropriate color based on the item value (or text):

    For Each item As ListItem In rdoTheTest.Items
        If item.Value = "1" Then
            item.Attributes.Add("style", "color: red")
        Else If item.Value = "2" Then
            item.Attributes.Add("style", "color: orange")
        Else 
            item.Attributes.Add("style", "color: green")
        End If
    Next
