help plz!! Replace bit value with Image and bind it to repeater

[sanju]

Hi,

I am struggling to replace a bit value 'True' or 'False' with a image
true.gif or false.gif and bind it to a repeater control.

I am getting values 'true' or 'false' depending on whether user is logged in
or not(with asp.net membership provider)

Getting true or false with this <%#
Membership.GetUser(Eval("UserID")).IsOnline %> and

getting the following error with this <%#
(Membership.GetUser(Eval("UserID", "Images/{0}.gif")).IsOnline)%>

plz help me to sort out this issue so that i can display image instead of
true or false.

Look at what you are asking here. Think it through for a minute:

Using membership and replace with a graphic by the name of the userid
Check if graphic is online

See a problem.

You are going to have to replace the string first and then bind. Without a
test, I do not have a sample of the code necessary and it might be
problematice even so.

Another option is the GridView (or DataGrid) data binding event, where you
can circumvent the natural order.

Also, how do you have this field set up? Is it templated with an image
control, or are you attempting to replace on the fly? If "on the fly" the
data binding event is your best option.
