ItemConstraintEventArgs 類別

提供 ItemConstraint 事件的資料。

命名空間：  Microsoft.Synchronization
組件：  Microsoft.Synchronization (在 Microsoft.Synchronization.dll 中)

語法

'宣告
Public Class ItemConstraintEventArgs _
    Inherits EventArgs
'用途
Dim instance As ItemConstraintEventArgs

public class ItemConstraintEventArgs : EventArgs

public ref class ItemConstraintEventArgs : public EventArgs

type ItemConstraintEventArgs =  
    class
        inherit EventArgs
    end

public class ItemConstraintEventArgs extends EventArgs

備註

ItemConstraintEventArgs 會在報告條件約束衝突時發生，代表衝突解決原則設定為 ApplicationDefined 時發生的衝突，以及所有非衝突條件約束衝突。

範例

下列範例會實作 ItemConstraint 事件的處理常式。此處理常式會向使用者顯示衝突項目，並且根據使用者的回應設定條件約束衝突解決動作。

Private Sub HandleItemConstraint(ByVal sender As [Object], ByVal args As ItemConstraintEventArgs)
    If ConstraintConflictReason.Collision = args.ConstraintConflictReason Then
        ' Display the two items that are in conflict and solicit a resolution from the user.
        Dim srcContact As New Contact(DirectCast(args.SourceChangeData, String()))
        Dim destContact As New Contact(DirectCast(args.DestinationChangeData, String()))
        Dim msg As String = ("Source change is " & srcContact.ToString() & vbLf & "Destination change is ") & destContact.ToString() & vbLf & "Click Yes to rename the source change and apply it." & vbLf & "Click No to rename the destination item and apply the source change." & vbLf & "Click Cancel to delete the destination item and apply the source change."
        Dim ccDlg As New ConstraintConflictDlg(msg)
        ccDlg.ShowDialog()

        ' Set the resolution action based on the user's response.
        args.SetResolutionAction(ccDlg.Resolution)
    Else
        args.SetResolutionAction(ConstraintConflictResolutionAction.SaveConflict)
    End If
End Sub

void HandleItemConstraint(Object sender, ItemConstraintEventArgs args)
{
    if (ConstraintConflictReason.Collision == args.ConstraintConflictReason)
    {
        // Display the two items that are in conflict and solicit a resolution from the user.
        Contact srcContact = new Contact((string[])args.SourceChangeData);
        Contact destContact = new Contact((string[])args.DestinationChangeData);
        string msg = "Source change is " + srcContact.ToString() +
                   "\nDestination change is " + destContact.ToString() +
                   "\nClick Yes to rename the source change and apply it." +
                   "\nClick No to rename the destination item and apply the source change." +
                   "\nClick Cancel to delete the destination item and apply the source change.";
        ConstraintConflictDlg ccDlg = new ConstraintConflictDlg(msg);
        ccDlg.ShowDialog();

        // Set the resolution action based on the user's response.
        args.SetResolutionAction(ccDlg.Resolution);
    }
    else 
    {
        args.SetResolutionAction(ConstraintConflictResolutionAction.SaveConflict);
    }
}
