I'm updating the number of the frozen columns of a grid in another modal form, and after I would like to see the changes in the grid after closing the modal form. Which action should I call?
Normally no additional action is needed to modify the number of frozen columns in RadGrid. It is enough to set the desired count either on the client-side or on the server. - [RadGrid].ClientSettings.Scrolling.FrozenColumnsCount = newCount;Setting the FrozenColumnsCount of a RadGrid affects the scrolling of the Grid which is entirely client-side functionality hence it should take effect right away, see Frozen Columns
