Content controls commands

The following commands related to the content controls functionality are available in the RadRichTextEditor:

• InsertStructuredDocumentTagCommand

In order to successfully execute the InsertStructuredDocumentTagCommand you have to pass the wanted content control type (SdtType) as a CommandParameter:

Example 1: Execute InsertStructuredDocumentTagCommand

this.radRichTextEditor1.InsertStructuredDocumentTag(SdtType.Picture);

Me.RadRichTextEditor1.InsertStructuredDocumentTag(SdtType.Picture)

Another way is to create a new instance of the InsertStructuredDocumentTagCommand and specify the SdtType in the Execute method:

InsertStructuredDocumentTagCommand command = new InsertStructuredDocumentTagCommand(this.radRichTextEditor1.RichTextBoxElement);
command.Execute("Picture");
//OR
this.radRichTextEditor1.Commands.InsertSdtCommand.Execute("Picture");

Dim command As InsertStructuredDocumentTagCommand = New InsertStructuredDocumentTagCommand(Me.RadRichTextEditor1.RichTextBoxElement)
command.Execute("Picture")
'OR
Me.RadRichTextEditor1.Commands.InsertSdtCommand.Execute("Picture")

• ShowContentControlPropertiesDialogCommand

In order to execute the ShowContentControlPropertiesDialogCommand you can create a new instance of the command and specify the SdtType in the Execute():

Example 2: Execute ShowContentControlPropertiesDialogCommand

ShowContentControlPropertiesDialogCommand command = new ShowContentControlPropertiesDialogCommand(this.radRichTextEditor1.RichTextBoxElement);
command.Execute("Text");
//OR
this.radRichTextEditor1.Commands.ShowContentControlPropertiesDialogCommand.Execute("Text");

Dim command As ShowContentControlPropertiesDialogCommand = New ShowContentControlPropertiesDialogCommand(Me.RadRichTextEditor1.RichTextBoxElement)
command.Execute("Text")
'OR
Me.RadRichTextEditor1.Commands.ShowContentControlPropertiesDialogCommand.Execute("Text")
