This example demonstrates how to implement select/unselect for all rows in a group row.
Added By: Cedric C at: 10/24/2017 6:15:09 AM I suppose the select all ability is implemented by this part of code:
But what is meant to do the 'checkBox_Load' callback?
First, place ASPxCheckBox and ASPxLabel into the ASPxGridLookup.GridViewProperties.Templates.GroupRowContent template.
Second, set the ASPxCheckBox.Checked property and the client-side ASPxCheckBox.ClientSideEvents.CheckedChanged event in the ASPxCheckBox.Load event handler.
In this example the ASPxLabel.Text is bound in the markup using Two-Way DataBinding.
