Hello Joseph,

Please note that when using GridHyperLinkColumn you set value to the DataTextField property and to the SortExpression property. Based on the value of these properties the grid knows which field to sort. When using ASP hyperlink control in GridTemplateColumn such property is not provided. So the grid does not know based on what field to sort. On the other hand GridTemplateColumn provides the SortExpression property as well which value should match the data field you want to sort on (typically the field a control in the template is bound to).
For more information you could review in details this online help.
