[Solved] RadGrid and System.OutOfMemoryException

[Jignesh]

We are using Telerik ASP.Net AJAX RadGrid and it has 1500+ Records to display.
We are not providing Grid Pagination as customers do not want the Grid to have Pagination.
On Production Servers,we are getting the below mentioned error.
The below mentioned error is from Event Logs.

On our local environment,a grid with 758 records is generating ViewState size of 0.42 MB.
I am using the RadGrid.ViewStateSize Property to get the size of ViewState.

So,is this error due to large amount of Viewstate that is been generated?.
Shall I disable the Viewstate on the Grid and re-design the Grid?
Please can you provide me any pointers?

Hello,

To resolved this issue i suggest to you, Please Use Clientside Binding.
//OR
You can also disable View State but before that please read/check Optimizing ViewState usage Document  / ViewState Optimization Demo in Radgrid.
