Creating a Custom RadGridView control

[Mark]

I have my own Grid Class based off of a RadGridView control, because I use the same formatting/settings in multiple places.  When I drag my grid to my form, everything seems fine, but when I add data to it, nothing is formatted.  The ROWS/COLUMNS have no formatting, no grid lines, etc. Not sure what I am doing wrong here.  Any help would be greatly appreciated. 

 

   public  class NtsRadGridView : RadGridView
   {
      #region Public Constructors

      public NtsRadGridView()
      {
         MasterTemplate.AllowAddNewRow = false;
         MasterTemplate.AllowCellContextMenu = false;
         MasterTemplate.AllowColumnChooser = false;
         MasterTemplate.AllowColumnHeaderContextMenu = false;
         MasterTemplate.AllowDeleteRow = false;
         MasterTemplate.AllowDragToGroup = false;
         MasterTemplate.AllowEditRow = false;
         MasterTemplate.AllowRowHeaderContextMenu = false;
         MasterTemplate.AllowRowResize = false;
         MasterTemplate.AllowSearchRow = true;
         MasterTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;
         MasterTemplate.ViewDefinition = new TableViewDefinition();
         ShowGroupPanel = false;
      }
}

Ok, I figured it out, I had to add a public override to the ThemeClassName property.  Once I did this, everything is working as it should be.

 

 

public override string ThemeClassName => typeof(RadGridView).FullName;

Hello Mark, 

Thank you for writing.  

I am glad that the problem you were facing is now resolved. The following help article is quite useful on this topic: http://docs.telerik.com/devtools/winforms/telerik-presentation-framework/inherit-themes-from-radcontrols-derivatives

I hope this information helps. Should you have further questions I would be glad to help.

I saw, from the link you posted, that this should be done for all derived controls.  I have other custom controls that are derived from Telerik controls, ie TextBox, MaskedEditBox, radSplitContainer, etc.and have not experienced the THEME issues like I did with my custom grid derived from the RadGridView.  Howerver, I can see how this should be a best practice.

Hello Mark, 

Thank you for writing back. 

Note that all controls in the Telerik UI for WinForms suite have their own style applied to the different elements of the structure of the internal elements. That is why in some controls you may not notice problems with the visual appearance at first sight.

If you have any additional questions, please let me know.
