  Hi,
  
  I'm getting an error "cannot convert type system.windows.forms.control to telerik.wincontrols.ui.radcarousel" when I try to convert a control to a radcarousel. Basically, this is the code (some code is missing but are irrelevant for this example):
  
  foreach (Control control in listOfControls)
  {
      if (c.getType() == button)
          listOfNames = control.Name;
  
      if(c.getType() == ToolStrip)
      {
          ToolStrip t = (ToolStrip)control;                         //here I have no problem when I try to cast a control to a ToolStrip control
          foreach (ToolStripItem tsi in t.Items) {...}
      }
  
      if(c.getType() == RadCarousel)
      {
          RadCarousel r = (RadCarousel)control;             //here I get the error
          foreach (RadButtonElement rbe in r.Items) {...}
      }
  }
  
  
  Thanks

  Hello Jordi Borras,

  Thank you for writing.
  
  You are not using the safe casting operators of C#. You need to use the "is" and "as" operators in order to safely cast from one type to another. Also, another issue with the code you posted is that you are calling GetType() on a variable named "c" and then casting a different variable named "control". Please review your code and apply the necessary modifications.
  
  Write again if you need further assistance.

  All the best,
  Victor
