event Microsoft.Office.Tools.Word.ContextChangeEventHandler ContextEnter;

member this.ContextEnter : Microsoft.Office.Tools.Word.ContextChangeEventHandler

Event ContextEnter As ContextChangeEventHandler

Event Type

ContextChangeEventHandler

Examples

The following code example demonstrates event handlers for the Select, Deselect, ContextEnter, and ContextLeave events. When the Select and Deselect events are raised, the event handlers add double lines to the borders of the selection or remove the double lines, depending on the event. When the ContextEnter and ContextLeave events are raised, the event handlers display messages that state the names of the newly selected node and the previously selected node. This example assumes that the current document contains an XMLNodes collection named SampleInsertNodes.

private void XMLNodesSelections()
{
    this.SampleInsertNodes.ContextEnter +=
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(
        SampleInsertNodes_ContextEnter);

    this.SampleInsertNodes.ContextLeave +=
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(
        SampleInsertNodes_ContextLeave);

    this.SampleInsertNodes.Select +=
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(
        SampleInsertNodes_Select);

    this.SampleInsertNodes.Deselect +=
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(
        SampleInsertNodes_Deselect);
}

void SampleInsertNodes_Select(object sender,
    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    e.Selection.Borders.OutsideLineStyle =
        Word.WdLineStyle.wdLineStyleDouble;
}

void SampleInsertNodes_Deselect(object sender,
    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    e.Selection.Borders.OutsideLineStyle =
        Word.WdLineStyle.wdLineStyleNone;
}

void SampleInsertNodes_ContextEnter(object sender,
    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    MessageBox.Show("You entered the node '" +
        e.NewXMLNode.BaseName + "'.");
}

void SampleInsertNodes_ContextLeave(object sender,
    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    MessageBox.Show("You left the node '" +
        e.OldXMLNode.BaseName + "'.");
}

Private Sub SampleInsertNodes_Select(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs)


    e.Selection.Borders.OutsideLineStyle = _
        Word.WdLineStyle.wdLineStyleDouble
End Sub

Private Sub SampleInsertNodes_Deselect(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs)


    e.Selection.Borders.OutsideLineStyle = _
        Word.WdLineStyle.wdLineStyleNone
End Sub

Private Sub SampleInsertNodes_ContextEnter(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs)


    MessageBox.Show("You entered the node '" & _
        e.NewXMLNode.BaseName + "'.")
End Sub

Private Sub SampleInsertNodes_ContextLeave(ByVal sender As Object, _
    ByVal e As Microsoft.Office.Tools.Word.ContextChangeEventArgs)


    MessageBox.Show("You left the node '" & _
        e.OldXMLNode.BaseName + "'.")
End Sub

Remarks

The ContextEnter event differs from the Select event. The ContextEnter event is raised only when the context changes and can be raised for multiple XMLNodes controls nested at the same hierarchical level. For more information, see XMLNodes Control.
