Hi Rohit,
Thank you for your interest in Syncfusion products.
Regarding to the freeze columns. Please refer our browser sample from our DashBoard, it contains GridGroupingControl with freeze columns. Also refer the below documenation link get more information about our products.
http://help.syncfusion.com/ug_74/gridwin/default.htmlWe see that you have opened a few support inquiries in our Essential Grid Forum. In order to ensure that you get the timely support and direct access to a dedicated support engineer, we would recommend that you use your Direct Trac account to create support incidents. Direct Trac has a guaranteed response time of 24 hours and access to a dedicated support engineer for ongoing support until resolution. The Forum is for general information sharing, while Direct Trac is more suited for the custom support that you require. We therefore hope that you will take advantage of the Direct Trac developer support system.
Regards,
Lngaraj S.
