public void EndUpdate()
Public Sub
Enclose your code in the BeginUpdate() - EndUpdate method calls to improve performance when you apply multiple modifications to a document.
Each call to BeginUpdate() must be paired with the EndUpdate call. You can use the try…finally statement to ensure that EndUpdate is always called even if an exception occurs.
The following example shows how to use the BeginUpdate() - EndUpdate methods.
// Create a new RichEditDocumentServer instance.
RichEditDocumentServer richEditDocumentServer = new RichEditDocumentServer();
richEditDocumentServer.BeginUpdate();
try
{
// Create a multiplication table.
Table table = richEditDocumentServer.Document.Tables.Create(richEditDocumentServer.Document.Selection.Start, 8, 8, AutoFitBehaviorType.AutoFitToWindow);
table.Borders.InsideHorizontalBorder.LineThickness = 1;
table.Borders.InsideHorizontalBorder.LineStyle = BorderLineStyle.Double;
table.Borders.InsideVerticalBorder.LineThickness = 1;
table.Borders.InsideVerticalBorder.LineStyle = BorderLineStyle.Double;
table.TableAlignment = TableRowAlignment.Center;
table.ForEachCell((cell, rowIndex, columnIndex) =>
{
richEditDocumentServer.Document.InsertText(cell.Range.Start, String.Format("{0}*{1} = {2}",
columnIndex + 2, rowIndex + 2, (rowIndex + 2) * (columnIndex + 2)));
});
}
finally
{
richEditDocumentServer.EndUpdate();
}
' Create a new RichEditDocumentServer instance.
Dim richEditDocumentServer As New RichEditDocumentServer()
richEditDocumentServer.BeginUpdate()
Try
' Create a multiplication table.
Dim table As Table = richEditDocumentServer.Document.Tables.Create(richEditDocumentServer.Document.Selection.Start, 8, 8, AutoFitBehaviorType.AutoFitToWindow)
table.Borders.InsideHorizontalBorder.LineThickness = 1
table.Borders.InsideHorizontalBorder.LineStyle = BorderLineStyle.Double
table.Borders.InsideVerticalBorder.LineThickness = 1
table.Borders.InsideVerticalBorder.LineStyle = BorderLineStyle.Double
table.TableAlignment = TableRowAlignment.Center
table.ForEachCell(Sub(cell, rowIndex, columnIndex)
richServer.Document.InsertText(cell.Range.Start, String.Format("{0}*{1} is {2}",
columnIndex + 2, rowIndex + 2, (rowIndex + 2) * (columnIndex + 2)))
End Sub)
Finally
richEditDocumentServer.EndUpdate()
End Try
