Hello,

You can handle the bound event:

function WebDataTree1_DataBound(sender, eventArgs)
{
 ///<summary>
 ///
 ///</summary>
 ///<param name="sender" type="Infragistics.Web.UI.WebDataTree"></param>
    ///<param name="eventArgs" type="Infragistics.Web.UI.DataTreeNodeRangeEventArgs"></param>
    for (var i = 0; i < 599; i++) {
        sender.getNodes().getNode(i).set_isEmptyParent(true);
    }
       // debugger;
 //Add code to handle your event here.
}

and set empty parent there. However this appoach is not designed to work. Normaly if you set the empty parent there will be invoked server side NodeClick. When you have client side rendering this will not happen because on the server you dont know about the datasource and you dont know which node is clicked. I advice you to reconsider your approach with our WebDataTree.

Hi,

Thanks for the quick reply,how can we assign the "set_isEmptyParent" in this example.

Suppose i will get the child count from the database.if child count is Greater than zero.i will set true to a boolean value. then, how to assign this Boolean to the node, so that to set parent is having child.

 

Thanks in Advance.

Hi,

 

Thanks for ur Quick Reply,i have binded the webdatatree using the ajax post method, but the problem is that it take more time to bind and the browser is returning the "A script on this page is causing Internet Explorer to run slowly" .There are around 6000 records to be bind to the webdatatree.

Or Do we have any solution like binding a limited records one in a time and after scrolling the tree then binding the remaining.

Can u provide me any solution.

 

Thanks in Advance
