  Hi,

  As per our understanding, you want to disable the Fullscreen button in the toolbar so that users cannot toggle fullscreen mode, since you are using the C1ReportViewer inside a C1Dialog.

  For this, you can use the C1ReportViewer.ToolBar property as follows:

  protected void Page_Load(object sender, EventArgs e)
  {
      C1ReportViewer1.ToolBar.Controls[11].Visible = false;
  }

  Please see the attached sample project for reference - ReportViewerFullscreen.zip

  Best Regards,
  
  Kartik

  Hi,

  There isn’t a reference available for the entire toolbar. You can simply inspect the list of controls in the C1ReportViewer.ToolBar.Controls collection using the Visual Studio debugger and hide them as needed.

  Ok, thanks, maybe using ?

  Print report button in the toolbar:
  Save button or the Save button's drop-down arrow in the toolbar
  Continuous view button on the toolbar:
   Zoom In, Zoom Out, and Current Zoom options on the toolbar
   Navigation options include an Outline pane and page navigation buttons on the toolbar.
  

  public partial class ToolBarCustomization : System.Web.UI.Page
  	{
  		protected void Page_Load(object sender, EventArgs e)
  		{
  			HtmlGenericControl toolbar = this.C1ReportViewer1.ToolBar;
  			for (int i = toolbar.Controls.Count - 1; i >= 0; i--)
  			{
  				string className = ((HtmlGenericControl)toolbar.Controls[i]).Attributes["class"];
  				if (!string.IsNullOrEmpty(className) && className.Contains("print"))
  				{
  					// remove "print" button
  					toolbar.Controls.RemoveAt(i);
  				}
  				if (i > 6)
  				{
  					toolbar.Controls.RemoveAt(i);
  				}
  			}
  		}
  	}
