  Hello,

  Thank you for sharing the sample. I can observe that for the disabled column, hovering mouse does not highlight the row.
  
  However, as per my understanding this is by-design since Microsoft documents “Elements that are not enabled do not participate in hit testing or focus and therefore will not be sources of input events.”. And because of this grid’s MouseMove event does not get triggered for this column to highlight the row.
  
  To workaround this, I would suggest you to set the IsEnabled property of the TextBlocks (in CellTemplate, CellEditingTemplate) rather than setting it for the DataGridCellPresenter
  
  I modified the application and attached here for your reference.

  Microsoft documentation (See Remarks section): https://docs.microsoft.com/en-us/dotnet/api/system.windows.uielement.isenabled?redirectedfrom=MSDN&view=netframework-4.7.2#System_Windows_UIElement_IsEnabled

  Do let me know if you need any further assistance.

  Thanks,

  Hi,

  Thank you for sharing the file. I have further modified my application (Observe the LoaderRowPresenter event).
  
  Could you please try the sample and see if it meets your requirement.

  Hello,

  Thank you for your respond!

  But when set IsSelected = “False”, the Textbox can not be edited in the next column, This is not what I want and I need set IsEnable = “False” in Cellstyle,not set in Textblock and textbox.

  I saw in .dll DatagridCellPresenter you set VisualState = “Disabled” when IsEnable = “False”. Do you understand and Can you help me?

  Thanks!
