My question is are there ways to get control row by row of what a datagrid does, based on values of the dataset the datagrid is bound to? For example, I have a dataset with values. The datagrid displays these. A user can click edit to edit the row, which brings up a control designated in the edittemplate tag, textbox, listbox, etc. I want to be able to either disable the edit linkbutton from appearing, or disable the edittemplate item control, if the row has a certain value in one of its fields. Is this possible? Does this even make sense?
