I am using radTreeView with server side postback. The tree has 2 levels.

I have implemented scrolling functionality on the treeView so that the tree automatically scrolls to a particular node when the page loads.

So in cases when there are large number of nodes (1000), the page is slow to load and many times the mouse click does not trigger the OnClicked event. 

So if the page is refreshed, the tree does not scroll to that particular node.

 

How can I improve the performance of the radTreeView using server side postbacks only ?

Hello Sidhant,

We do not have an advice for improving the performance of the TreeVew when using server-side postbacks mode, except for wrapping the TreeView in a RadAjaxPanel as mentioned in the Optimizing RadTreeView Performance documentation article. This is the slowest of the three Load on Demand modes.

We tried putting the RadTree inside a RadAjaxPanel, but it did not produce any satisfactory results.

Also, the steps given on "Optimizing RadTreeView Performance" page did result in any sort of resolution.

What else can we try to improve the performance of RadTreeView while using server side postbacks?

Hello Sidhant,

As I mentioned in my previous reply we do not have other optimization tips for the Server Side PostBack, which by design is the slowest of the LOD modes. If there is no significant performance improvement when using a RadAjaxPanel or UpdatePanel we would suggest you to consider using one of the other LOD modes, since their performance is better compared to the Server Side PostBack mode.
