Parameters

table

A reference to the WebGridTable object.

column

The column name of the clicked button.

cellValue

The button cell's value. This value is available for Bound column and DataMember is specified.

Return Value

The user-defined function should only contain the name of the function. For example, "HandleEvent". This event allow developers to easily capture the button click event and process implementation further. Button ColumnType now has ability to perform postback to server automatically by setting the ButtonAutoPostBack to True. You can even choose whether the postback would be performed using OnTheFly(tm) postback for fast response or FullPageRefresh. This setting can be found in ButtonPostBackMode property. When ButtonAutoPostback is set to True, the ButtonClick server event will be invoked as well for both PostBackMode. You can cancel postback to occur by setting the return to false in this event.

Note that you should include the return value of your function. Returning a true value means that default behavior will be processed. Otherwise, the default behavior will be skipped.
