Hello Anton,

Thank you for posting in our community.

What is this TargetUrl that you're using in the grid cell? Are you using ItemTemplate with LinkButton control inside of it? If this is the case, then please take a look at the "Using Item Template" documentation: http://help.infragistics.com/Help/Doc/ASPNET/2013.2/CLR4.0/html/WebDataGrid_Using_Item_Template.html, which explains in details how to add LinkButton as TemplateDataField in the grid and handle its click event.

Meanwhile I'm attaching you also a sample with similar scenario for your reference.

Please let me know if you have any further questions.

Sincerely,

Tsanna
