Rich,

Bindevent is the way to go. Take a look at the complete implementation at this blog
Grid class that allows sorting by clicking on headers


>I inherited a custom grid class. The definition of the grid shows a ColumnCount of 30. Three methods of EACH column in the grid have code in them.

>We've run into a situation where the ColumnCount for the grid needs to expand beyond 30 columns. Our "solution" is to expand the numbe of columns (to 50) and put this code into each new column's header/text box. This solution works and is therefore, by our definition, acceptable and has been implemented.

>OTOH, it seems to me that there should be a better solution by taking all this code out of the column header and text box and somehow using BINDEVENT() to get everything working. I don't have enough familiarity with BINDEVENT to do this and my (admittedly meager) efforts have been fruitless.
