The DataError event enables you to handle exceptions that are thrown in code that is called by a DataRepeater control during data processing operations.

The ThrowException property can be used to raise an Exception if the data error is not corrected by the user.

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
