Modify RadRichTextEditor Content Control Text Programically

[Ali]

Hello

I want to be able to modify the text content of the control programmically at runtime. Below is the code I have tried :

 Placeholder does not change the content

 Dim content_controls As IEnumerable(Of SdtRangeStart) =
        Me.radRichTextEditor1.Document.GetAnnotationMarkersOfType(Of SdtRangeStart)()
        For Each item In content_controls
            'MsgBox("Type: {0} ID:{1}", item.SdtProperties.Type, item.SdtProperties.ID)
            'MsgBox("Type: {0} ID:{1}", item.SdtProperties.Type, item.SdtProperties.ID)

            If item.SdtProperties.Type = SdtType.Text Then

                Dim properties As TextProperties = TryCast(item.SdtProperties, TextProperties)
                If properties.Tag IsNot Nothing AndAlso properties.Tag.ToUpper = "SERIALNO" Then
                    properties.Placeholder.PlaceholderText = "DWF324434244242"
                    properties.Placeholder.ShowPlaceholder = True
                End If
            End If
        Next

Thank You

Hello Ali,

If the content controls already have contend the place holder text would not be displayed. You can change the actual content with the following approach (you need to update the layout as well): 

Dim content_controls As IEnumerable(Of SdtRangeStart) = radRichTextEditor1.Document.GetAnnotationMarkersOfType(Of SdtRangeStart)().ToList()
For Each item In content_controls
	If item.SdtProperties.Type = SdtType.Text Then
		Dim span As Span = TryCast(item.NextSibling, Span)
		If span IsNot Nothing Then
			span.Text = "DWF324434244242"
		End If
	End If
Next item

radRichTextEditor1.UpdateEditorLayout()

Let me know if I can assist you further.

Hello

I want to be able to bind the span or control to a datasource, kindly assist me with the below code or other alternative;

  span.BindProperty(propertyToBind, bindingSource_renamed.Current, sourceProperty, PropertyBindingOptions.TwoWay)

 

Thank You

Hi Ali

This is not supported and is not recommended (elements instances can be cloned or recreated at some point). Could share more information about your scenario? Perhaps I can suggest an alternative solution. 

I am looking forward to your reply.
