In my application, I frequently use multiple DropDownLists on the same page. Most of the time, the data sources for those lists (which are connected to a SQL Server database) load quickly and there's no problem. Every once in a while, however, the load hangs and all the dropdowns show the spinning 'loading' icon. Sometimes they resolve on their own and finish loading. Sometimes they throw one of several errors that I know relate to simultaneous SQL transactions running in the database (I apologize, I don't have the error text for any of them at the moment, but I will update this thread if and when I do).

Anyone know about this issue or have suggestions on how I can avoid the problem and improve performance?

Hello Jacob,

It sounds like the issue you have is coming from your database layer and it is not related to Kendo. I would suggest you to search the internet for resolutions or tips.

Also asking a detailed question on the Stackoverflow forums might be of help.
