Example to force form control to failed in Kentico BizForm - Code Behind

This is a example to manually force stop the bizform to continue processing save data and show error message to the Field Form Control.

Note this is just example. You may use this approach to set very complex validation on the Field in BizForm.

OnLoad Method

   protected override void OnLoad(EventArgs e)  
   {  
     viewBiz.OnAfterSave += viewBiz_OnAfterSave;  
     viewBiz.OnBeforeSave += viewBiz_OnBeforeSave;  
     base.OnLoad(e);  
   }  

OnBeforeSave Method

  void viewBiz_OnBeforeSave(object sender, EventArgs e)  
   {  
     //get the field form controller  
     FormEngineUserControl fieldFormController = viewBiz.FieldControls["<field name>"];  
     if (fieldFormController != null)  
     {  
       //do custom validation - example fieldFormControl dont have text "*"  
       if (!fieldFormController.Text.Contains("*"))  
       {  
         //stop biz form from continue processing  
         viewBiz.StopProcessing = true;  
         //focus the field / form controller  
         fieldFormController.Focus();  
         //show error message  
         viewBiz.DisplayErrorLabel("<field name>", "Field must have character \"*\"");  
       }       
     }  
   }
