Improve the Performance of updating sharepoint list item from a Grid

[smith spd]

Hello Telerik team,

I have a requirement where i have a Telerik rad grid which has a datasource of sharepoint list.
When you edit a record from the rad grid, I have to update the particular record and update the record.

I have a sharepoint list which have more than 150 columns in it.I am using sharepoint object model to update the sharepoint list item by saying
listitem.update();
 When I do that,it takes a lot of time to update the record.Is it because of so many columns or
i have more than 20000 records in the sharepoint list.Is there any better way of doing it.

One of my thought is that it might be taing so much time on update as
it has to create the content type for that particular list item.
Is there any way that if we can already define a content type for that list so that
the process of updation will become fast.

Any ideas to improve the performace is greatly appreciated.

Thank you,
Smith

Hi Smith,

I am afraid that the cause of the performance issue is the large number of items. Please, go through the following help article and all the related topics under the Performance Tips and Tricks (here). The implementation of some of those should provide some alleviation to the problem.
