JS Grid Delegates
Published: May 2010
The JS Grid control supports a variety of delegates. Using these delegates provides you a greater degree of control over the behavior of the JS Grid control.
The following table lists the JS Grid delegates.

Used when the column drop-down menu is activated.
AddColumnMenuItems is called only if WillAddColumnMenuItems returns true for this column and if ExpandColumnMenu delegate is not present.
Called when a column header menu is pulled down and an autofilter item is selected.
Called as soon as some data is entered for a new row.
Called by the grid to request that the page delete currently selected records.
