[DevExpress Support Team: CLONED FROM T707120: How to filter data with DataSourceLoadOptions on the server]
Hi Ilya,

Here is one issue i found in above code like if suppose i have more than 200 CCount selected row by user then it is throwing client side error like 404 not found. When i checked in Network tab of Developer tools in browser then get to know that when application url is passing CCount value as Query string then it reaches the limit of it and due to it is throwing error.

Kindly provide the solution for it.

Thanks,

Vikash

Hi Veera,

It looks like you encountered the issue described at DataGrid cannot pass a long filter expression to the server after the selectRows method is used. The DevExtreme.AspNet.Data library provides the LoadMethod option in the recent versions. If you set it to "POST", all parameters will be passed in the request body. Please review the attached example illustrating this idea.
Note that DevExtreme.AspNet.Data documentation is located on GitHub. I recommend you use it to see what options and methods can be used for different cases.

Let us know if you have additional questions.
