Examples

The following example demonstrates how to use the data from a DataRepeaterDataErrorEventArgs to display a message when a data error occurs.

private void dataRepeater1_DataError(object sender, 
    Microsoft.VisualBasic.PowerPacks.DataRepeaterDataErrorEventArgs e)
{
    string ErrorMsg;
    // Create an error string.
    ErrorMsg = "Invalid value entered for " + e.Control.Name + ". ";
    ErrorMsg = ErrorMsg + e.Exception.Message;
    // Display the error to the user.
    MessageBox.Show(ErrorMsg);
    // Do not raise an exception.
    e.ThrowException = false;
}

Private Sub DataRepeater1_DataError(
    ByVal sender As Object, 
    ByVal e As Microsoft.VisualBasic.PowerPacks.DataRepeaterDataErrorEventArgs
  ) Handles DataRepeater1.DataError

    Dim ErrorMsg As String
    ' Create an error string.
    ErrorMsg = "Invalid value entered for " & e.Control.Name & ". "
    ErrorMsg = ErrorMsg & e.Exception.Message
    ' Display the error to the user.
    MsgBox(ErrorMsg)
    ' Do not raise an exception.
    e.ThrowException = False
End Sub
