ContextLeave Event

XMLNode.ContextLeave Event

 

Occurs when the cursor is moved from the XMLNode control, or one of its descendent nodes, to an area outside of the context of the original node.

Namespace:   Microsoft.Office.Tools.Word
Assembly:  Microsoft.Office.Tools.Word (in Microsoft.Office.Tools.Word.dll)

event ContextChangeEventHandler ContextLeave

The ContextLeave event differs from the Deselect event. The ContextLeave event is raised only when the context changes. For more information, see XMLNode Control.

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 XMLNode named CustomerNode.

private void XMLNodeSelections()
{
    this.CustomerNode.ContextEnter +=
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(
        CustomerNode_ContextEnter);

    this.CustomerNode.ContextLeave +=
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(
        CustomerNode_ContextLeave);

    this.CustomerNode.Select += 
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(
        CustomerNode_Select); 

    this.CustomerNode.Deselect +=
        new Microsoft.Office.Tools.Word.ContextChangeEventHandler(
        CustomerNode_Deselect);
}

    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    e.Selection.Borders.OutsideLineStyle =
        Word.WdLineStyle.wdLineStyleDouble;
}

    Microsoft.Office.Tools.Word.ContextChangeEventArgs e)
{
    e.Selection.Borders.OutsideLineStyle =
        Word.WdLineStyle.wdLineStyleNone;
}

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

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