How to access webpart method from another webpart - Kentico

This tutorial is to show how to access web part method from another webpart. This situation basically when you use repeater(webpartA) and inside repeater transformation you call another User control / webpart(webpartB). Everytime the you trigger event on the webpartB (ie: click, change value, etc), you want to refresh the webpartA value. But you cannot access the method directly.

Code Behind repeater / WebartA

Override OnInit Event

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

Code Behind UserControl / WebpartB

Called ReloadData() from another webpart.

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

Thats all.
