Hi Reema,
Thank you for your interest in Syncfusion Products.
Please follow the below steps to deploy ASP.NET applications that use Essential Grid.
1) Marking the Application directory
-----------------------------------
The appropriate directory, usually where the aspx files reside, must be marked as Application in IIS.
2) Syncfusion Assemblies
----------------------
The Syncfusion assemblies need to be in the bin folder that is beside the aspx files. They can also be in the GAC, in which case, they should be referenced with strong name(s) in the aspx files and dlls.
3) Data files
-------------
If you have template document files, .mdb files or other data files, ensure that they have sufficient security permission. The Authenticated Users should have full control for the files and the directory to give ASP.NET code enough permission to open the file during run-time. Please refer the below link to get more details on this issue:
