Timeout Problems

[Mike]

Hello,

I've been having a number of problems with a treeview control on a page I'm using. Many users (including myself) get a request timed out error when the treeview rebinds. So basically, I add an item to the tree, and it just sits and the refresh won't happen. The item does add to the tree and it appears to complete the code on my end, it just gets stuck trying to rebuild the tree or something.

Has anyone else run into this kind of thing?

Thanks,

Mike

Hi Mike,

Timeouts usually occur if a time-consuming event happens on the server and it takes too long to complete or never does. For instance, binding to a huge dataset, generating thousands of Nodes, infinite loops, etc.

Could you please check whether such an event takes place in your application at some moment?

Hello,

Thanks for your reply.

I don't think that's an issue. It is bound to a db... but I fill the tree from code on the server.... Usually with very few nodes - usually as low as 5 or 10... and with no children.

In debug mode, whenever I've replicated it (the issue only happens sometimes), my code runs just fine, then after it finishing running the code on the server, it hangs building the page.

When it works, it usually is almost instantaneous. So the build happens right away... but every now and then it seems to get hung up.

Hello Mike,

Indeed this is strange as the TreeView is unlikely to cause such timeouts.

Could you try removing the TreeView from the page and test to see whether the timeouts continue to occur or stop completely?

All the best,

Hello,

Sorry for the delay in getting back on this - been pretty busy. I am almost positive it's the treeview. Unfortunately, I can't remove it from the page. The timeouts only occur though with postbacks involving the treeview. I watched the thing in firebug and it found the error below... maybe it will help.

Thank you... and again, I'm sorry for the vague nature of this problem.

Mike

Hi Mike,

Thank you for the additional info.

Could you also try replacing RadScriptManager with ScriptManager? Does the problem still persist in this case?

Hello,

Let me just say again - thank you for the help - Telerik is really an amazing company...

Anyway - still having the problem after replacing the script manager. Here's the error from firebug (below).

I actually expanded it out this time... it had a few lines at the bottom I thought might help...

Some of these lines make reference to drag and drop functionality. So I actually tried eliminating that from the control as well... but that didn't help either.

Thanks,

Mike

Hi Mike,

This is a client-side error and should not cause server-side timeouts. Is there any live url where we can observe the problem? Alternatively you could open a support ticket and send us a sample project (or exceprt from your project).

We are getting out of ideas and I am afraid we cannot provide a solution unless we reproduce the problem on our side.
