[DotNetDevelopment] DropDownList DataBound

[Ana]

Hi, I have the following code:

Protected Sub MyDropDownList_DataBound(ByVal sender As Object, ByVal e
As System.EventArgs)
        Dim drv As DataRowView = MRFormView.DataItem
        Dim ddlValue As String = drv("value")
        Dim ddl As DropDownList = sender

        If Not IsDBNull(ddlValue) Then
            ddl.SelectedValue = ddlValue
        End If
    End Sub

Let's say  ddlValue = 100. While debugging, when I check the value for
ddlSelectedValue after the line ddl.SelectedValue = ddlValue,
ddl.SelectedValue is and empty String "", even though ddlValue = 100.

I know this must be something very simple that are missing, but anyone
have any suggestions of what is happening?

I appreciate your help!

Ana
