I have a TemplateField whose caption I want to set using a method to get the caption based on an Enum. I tried this:HeaderText='<% =GetCaption(MyEnum.First) %>'but it doesn't work. GetCaption() is never called.Data binding syntax (ie '<%# %>') won't work because TemplateField is not a databound control. I do not want to do this in the Page_Load event because I don't want to refer to the column by index as the index is prone to change.How can I do this?

Dear SGWellens, ...Dynamic setting of column name in stored procedure
Is it possible to send field name to stored procedure.
eg I want to fetch a single column of same type from the same table.
