Greetings,
I'm currently trying to revamp one of my pages from server side binding to a web service binding and encountered a hickup.
The page is as follows (see picture attached):
The Outside is a RadSplitter.
On the left side of the RadSplitter is an update panel, where inside is the RadTreeView.
On the right side, also inside an update panel, is a RadGrid.
The RadTreeView gets a basic set of nodes ("stations") on creation, but everything after that is loaded on demand by webservice. If a "station" is expaned, and the webservice is triggered and supplies nodes to the radgrid. This works correctly.
If I click on a "station", a client side event is triggered, which expands the node (therefore triggering the webservice and supplying nodes) and also calling the RadGrid to rebind (by client side). The Rebind triggers the OnNeedDataSource event of the RadGrid, where it loads its data server side.
The problem is with the click & expand, as the nodes are then only briefly visible in the RadTreeView and immediately removed again.
Is this a know problem? What can I do? I need the nodes in the tree but also the data in the RadGrid.
I made a video of the error, but it seems I cannot upload the video here. I also created a very basic test project.
I'm using Telerik 2023.1.117.45.
Thank you in advance!
Hello -
We are using Telerik forms for our internal website. When I download one page with all its components, it is 73 files and 11.2 MB total size. Screen captures attached.
Most of our site is made up of similar pages. Our site has an average 500 connections per second. During peak times, the website crawls, with 20-30 seconds to return one page for each user.
We are accessing only text, with about 200 KB of text returned for each request.
It looks like 99.3% of the size of our pages is Telerik related files (mostly axd and js).
What could we be doing wrong? What should we be doing differently to reduce the size or count of Telerik files returned to the client?
Thank you!
Hi,
Does the latest version of Telerik UI for ASP.NET AJAX support drag/drop between two TreeViews on the same page? How about two Grids?
Thanks,
