Question about creating columns

[Chris]

Does RadGrid offer any functionality that allows the user to create a column on a grid based on the location they click?  Thanks

Hi,

RadGrid does not support mixing declarative grid columns with grid columns added dynamically at runtime. You should either create all the columns in the grid programmatically, or else define them all in the ASPX file. A suggestion would be to use a header context menu to add columns dynamically to the grid. Check out the demo below to understand where they use the headercontextmenu to show or hide columns:
