Casting problem

I have a combobox that I populate with values from the database. And I have written a code in the SelectedIndexChanged property of the combobox to display the selected item in a label.

VB Code:

Private Sub cbxNationality_SelectedIndexChanged(ByVal sender As System.Object, _
  ByVal e As System.EventArgs) Handles cbxNationality.SelectedIndexChanged
        
    Try
        lblName.Text = cbxNationality.SelectedValue
        'lblName.Text = CType(cbxNationality.SelectedValue, String)
    Catch exp As Exception
        MessageBox.Show(Err.Number & ": " & exp.Message, Me.Text)
    End Try
 
End Sub

However, I get this error: 13: Cast from type 'DataRowView' to type 'String' is not valid.

The commented line too does not work.

Any help will be appreciated.

try

lblName.Text = cbxNationality.SelectedValue.ToString

I think the problem has to do with the datasource being a datarowview, because I don't get the error with a table or dataview as datasource for the combobox....

The data may look like a string, but it isn't, it's a DataRowView. Without a means to convert a DataRowView into a string, the language doesn't know what to do with the line you wrote. This is just a type safety issue which you'll have to live with. In VB6, it was possible to convert just about anything into a string in some manner, but in .NET it isn't quite as simple.

So what do you suggest I should do? Just a hint go get me in the right direction...

Try using the Row property of the DataRowView object to get the information from the dataset then.

Datarowview.Row.Item("ColumnInDataBase")
