DocumentRange.EndUpdateDocument(SubDocument) Method

Finalizes modifications of the document obtained via the document’s range (e.g. via selection).

Namespace: DevExpress.XtraRichEdit.API.Native

Assembly: DevExpress.RichEdit.v24.2.Core.dll

NuGet Package: DevExpress.RichEdit.Core

Declaration

C#

void EndUpdateDocument(
    SubDocument document
)

VB.NET

Sub EndUpdateDocument(
    document As SubDocument
)

Parameters

Name	Type	Description
document	SubDocument	A SubDocument instance obtained via the previously called DocumentRange.BeginUpdateDocument method.

Remarks

Use the DocumentRange.BeginUpdateDocument - DocumentRange.EndUpdateDocument pair to modify the document obtained via selection (i.e. by using the Document.Selection property). In that case, it is very important to distinguish different parts of the document, such as header, footer or body. The EndUpdateDocument method implements this requirement.

Example

The following code replaces the selected text with asterisks.

The RichEditControl instance is passed to the BarItem.ItemClick event handler using the BarItem.Tag property.

View Example

RichEditControlActions.vb

Private Shared Sub buttonCustomAction_ItemClick_Replace(ByVal sender As Object, ByVal e As ItemClickEventArgs)
    Dim richEdit As RichEditControl = TryCast(e.Item.Tag, RichEditControl)
    Dim range As DocumentRange = richEdit.Document.Selection
    Dim selLength As Integer = range.Length
    Dim s As New String("*"c, selLength)
    Dim doc As SubDocument = range.BeginUpdateDocument()
    doc.InsertSingleLineText(range.Start, s)
    Dim rangeToRemove As DocumentRange = doc.CreateRange(range.Start, selLength)
    doc.Delete(rangeToRemove)
    range.EndUpdateDocument(doc)
End Sub

RichEditControlActions.cs

static void buttonCustomAction_ItemClick_Replace(object sender, ItemClickEventArgs e) {
    RichEditControl richEdit = e.Item.Tag as RichEditControl;
    DocumentRange range = richEdit.Document.Selection;
    int selLength = range.Length;
    string s = new String('*', selLength);
    SubDocument doc = range.BeginUpdateDocument();
    doc.InsertSingleLineText(range.Start, s);
    DocumentRange rangeToRemove = doc.CreateRange(range.Start, selLength);
    doc.Delete(rangeToRemove);
    range.EndUpdateDocument(doc);
}
