At work I have old project which is on WebForms with Telerik UI. I don't know it because I learn newer technologies. The problem is that I have CheckBox which is generated like below. The problem is when I click on CheckBox I have to wait few minutes... It caused by Event OnInit, which trigger always when I click on any control I have on view. This event reloads my view so all data which were on view are re-rendered.

 private void AttributeValueListOnItemDataBound(object sender, TreeListItemDataBoundEventArgs e)
 
 //some unnecessary code 
 if (e.Item is TreeListDataItem)
 
 var item = e.Item as TreeListDataItem;
 var data = (AttributeValueListItem)item.DataItem;

 var cb = new CheckBox
 
 ID = "ActiveCB",
 Checked = data.Active,
 AutoPostBack = true
 ;

 if (data.AttributeValueParentID != null)
 
 cb.CheckedChanged += Active_CheckedChanged;
 
 else
 
 cb.CheckedChanged += Active_CheckedChildChanged;
 

 item["Active"].Controls.Add(cb);
 item["Description"].Text = data.Description;
 item["Prefix"].Text = data.Prefix;
 item.Expanded = true;
 
 

I expect that in this case, prevent this triggering OnInit event, or maybe you have other solution for prevent long waiting time...
