aven't looked into it yet - starting to go through various possibilities 
roundabout now, and this is in any case more of a recommendation to other 
developer about how to try make it work, but will still try give him an example 
or 2 to look at.

Something like JQuery does interest me in any case since seems like it might do 
a couple of other types of things I might like to make use of at some stage, 
but the ASPX list view, templatised might in fact be the quickest/easiest way 
to do what they want right now.

Stay well

  Hi Guys: Again I would recommend looking at the ASP ListView control. It 
allows you to use a templated html setup to format outputs. I believe You could 
just  bind the ListView to the data then specify either a couple of list or 
tables as the rendered outputs. Then, in the templates, set up the headings to 
remain fixed and the data columns to scroll. I'm not sure about this but it 
deservs a look since the real question here is picking the right tool for a job 
and perhaps the DataGrid or GridView is not the right tool for this job. If it 
is, Scott Mitchell has  a step by step article describing using html to set up 
a webpage as desired. Other approaches including CSS and JQuery are more 
complex and used to get around the GridView's inherrant flaws in this respect. 
Anyway, I have not seen any discussion on whether the tool mentioned, GridView 
or whatever it is now called, is the best tool for the job at hand. 
  Is it because you know it is not the correct tool from experience or because 
you have just never used it? Just asking because I found the ListView good for 
another purpose and it is quite flexible once you understand how it works.

    You could do that, yes, but if you clone the header row with jQuery you 
probably wouldn't have to. Unless your columns are being sized by the content 
of the data rows.

      Ok, that also makes sense.

      In other words, a javascript function would go and set the column widths 
for the header table to the same as the widths of the actual data displaying 
table columns?

        is not necessary jquery.
        With only javascript it is enough to do this.

          JQuery?

          I'm somewhat out of practice with this type of web development - 
obviously...<smile>

            Well, somebody mentioned a MX data grid which I have never used.
            But what you could do is to put the datagrid in a div with overflow 
set to auto.
            Then, with jQuery, it should be quite trivial to clone the header 
row and insert it in another div right above the data grid's div and hide the 
original header row.
            With a little fiddling that should give you the static headers you 
are aiming for.

              Don't think there are too many guys involved in/looking into 
ASP.Net on VI programming lists, but specifically, at the moment, trying to 
figure out how to implement static/unmoving column headers for an ASP.Net 
datagrid, with the specific issue being that since there are quite a few 
datarows being rendered in a datagrid, they want the column headers to stay 
static/floating above the then scrollable columns of data, and was just 
wondering if anyone had ideas off hand.

              My own would be to in fact implement a static HTML table above 
the datagrid, with the column headers in it, and then implement the datagrid in 
something like either an inline frame, or a normal frame to allow the browser 
to scroll up and down inside it, while still seeing the column headers above, 
but the primary issue so far is I don't seem to be able to query/find a 
rendition of the column widths etc. from the datagrid control, but have 
otherwise been thinking about in fact chucking out the datagrid control as 
such, and just something closer to older, classic ASP to in fact just render 
the HTML output version of something like this, and would then just base the 
column widths on something like a certain number of pixels/points per letter of 
the column name, and would then use something closer to the classic ASP/PHP 
outputting of the data table inside another frame or something.

              Thoughts/examples/suggestions?
