LinqDataSourceValidationException::InnerExceptions Property
Gets one or more exceptions that occurred when new or modified data was being validated.
Assembly: System.Web.Extensions (in System.Web.Extensions.dll)
public: property IDictionary<String^, Exception^>^ InnerExceptions { virtual IDictionary<String^, Exception^>^ get() sealed; }
Property Value
Type: System.Collections.Generic::IDictionary<String^, Exception^>^A collection that contains the exceptions.
The InnerExceptions collection contains all the validation exceptions that were thrown during data validation before an update, insert, or delete operation. A validation exception can occur if a value does not match the type of the property. For example, if you try to update an integer property by using non-numeric characters, a validation exception is thrown. A LINQ to SQL class can also contain customized validation criteria that make sure that the property contains a value that is within an expected range or pattern.
The following example shows an event handler for the Updating event. It displays any validation exception messages by using a Label control.
Protected Sub LinqDataSource_Updating(ByVal sender As Object, _ ByVal e As LinqDataSourceUpdateEventArgs) If (e.Exception IsNot Nothing) Then For Each innerException As KeyValuePair(Of String, Exception) _ In e.Exception.InnerExceptions Label1.Text &= innerException.Key & ": " & _ innerException.Value.Message & "<br />" Next e.ExceptionHandled = True End If End Sub
[C#]
protected void LinqDataSource_Updating(object sender,
LinqDataSourceUpdateEventArgs e)
{
if (e.Exception != null)
{
foreach (KeyValuePair<string, Exception> innerException in
e.Exception.InnerExceptions)
{
Label1.Text += innerException.Key + ": " +
innerException.Message + "<br />";
}
e.ExceptionHandled = true;
}
}
