How to change the properties/method of one web part from within another web part - Kentico

-
This tutorial is to show how to access the web part properties/method from another web part. This situation basically when you use a repeater name repeater1 and inside repeater transformation you call another User control/web part name repeater2. Every time you trigger an event on the repeater2(ie: click, change the value, etc), you want to refresh the repeater1 value. But you cannot access the properties/method directly.

Code Behind repeater / repeater1

Override OnInit Event
   protected override void OnInit(EventArgs e)  
   {  
   
     RequestStockHelper.Add("repeater2", this); 
     base.OnInit(e);  
   }


Code Behind UserControl / repeater2

Called ReloadData() from another webpart.
   protected void LinkButton1_Click(object sender, EventArgs e)  
   {         
        
        CMSAbstractWebPart webpart = RequestStockHelper.GetItem("repeater2") as CMSAbstractWebPart;
        if (webpart != null)
        {            
            webpart.OnContentLoaded();
        }  
   }
