GRIDVIEW: changing column attributes

[Guest]

I have a gridview with some boundfields and buttonfields, and based on the
user's role I want to modify their attributes: for example, if the person's
role doesnt allow updates, I want to set a buttonfields visible attribute to
"false". I know how to get data values from a clicked column, but I havent
been able to find out how to modify the columns such as in the above scenario
when the gridview loads.
Any help is very appreciated.

If you use a TemplateField instead of a BoundField for the columns that you
wish to change its visibility based on the user role then you can write
something like this:
<asp:TemplateField>
<ItemTemplate>
<asp:Label ID="Label1" runat="server"
Text='<%# Bind("OrderDate", "{0:d}") %>'
Visible='<%=SomeProtectedFunctionThatReturnsBool()'></asp:Label>
</ItemTemplate>

where SomeProtectedFunctionThatReturnsBool would be a function in your
codebehind that decide whether the user has access of not.

Mark,

In addition to Phillip's answer, I think that you could do something like
this: Set up a RowDataBound event handler for your GridView. You can then
set the visible attribute of a buttonfield like this:

Button button = (Button)e.Row.Cells[1].Controls[0];
button.Attributes.Add("visible", "false");

Of course, the index that you use to access the right cell will vary
depending on the layout of your grid. I used Cells[1] just as an example.
