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.
