Content controls commands

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);

Dim command As InsertStructuredDocumentTagCommand = New InsertStructuredDocumentTagCommand(Me.RadRichTextEditor1.RichTextBoxElement)

  • 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);

Dim command As ShowContentControlPropertiesDialogCommand = New ShowContentControlPropertiesDialogCommand(Me.RadRichTextEditor1.RichTextBoxElement)
