Hello Prakash,

In case the controls are not showing inside the Visial Studio Toolbox once you installed version 21.2, I recommend you reviewing the following article, which explains how the controls could be added manually by creating a custom tab in the toolbox and copying the DLLs into it.

The DLLs could be accessed in the following directory:

C:\Program Files (x86)\Infragistics\2021.2\ASP.NET\CLR4.5\Bin

Please note that the directory may vary, depending on where you have installed Infragistics components. If you have any questions don’t hesitate to ask.

Regards,
Ivan Kitanov
