I have a Grid with link buttons inside of template fields. This grid is created after various drop down selections are made. Once a link button is clicked from inside this "Master" grid, information from that button gets passed to a SQL query to populate a second Grid that is contained within a ModalPopupExtender. When this grid is databound I would like to resize all the columns to fit the contents. I have found this on this site: http://www.telerik.com/forums/radgrid-columns-width-fit-the-content-of-the-columns
However, my grid is not bound on pageLoad. How can I get my "Pop Up" grid to set columns to autowidth when it is bound after the link button click from the "Master" grid? The Grid is bound to a datatable that is returned from a stored procedure and then the ModalPopupExtender is called with mpe.Show(); . At present I am setting the width of the grid and all the bound columns to get the desired look. I have many more grids to populate on this page in similar ModalPopupExtender's. I would hate to have to set the width's for all grids.
Here is the aspx code for the MPE and RadGrid:
