Helo All,

The problem: GridView control does not render at all (header/footer) when
the data source is empty.
I have seen a similar question posted already, but I just can not believe
there is no simple solution.
I do not believe ASP.Net team took this, sort of, innovative approach and
left no way out.
Could anybody advise?

Thank you,
Tomasz

1) Launch your internet browser (e.g. IE, FireFox, Netcape, Opera etc)

2) Navigate to http://www.google.com

3) Enter the text below in the box:

GridView DataSource empty

4) Hit the button

Yeah, I think I have forgotten to to emphasize the word SIMPLE.

Perhaps the emptydatatext property of gridview would be simple enough

Simple - yes, helpful - I do not know. Setting this property does not seem
to cause header/footer to render when data source is empty. Am I missing
something?

Thanks,
Tomasz

That's certainly the way I do it...

Apparently, MS doesn't consider this an issue and does not intend to change
it.
I submitted it to feedback and this is the result.
http://connect.microsoft.com/VisualS...dbackID=228384

While I haven't used it in production as yet, I am currently building a site
using the following, with a few tweaks.
http://www.codeproject.com/useritems...nsert_line.asp
If you want to be able to insert data, it works fine, except for one typo I
found.
If you just want to display header and footer without the insert, I think
you can easily modify it to do that.

The line:
public event GridViewUpdatedEventHandler RowInserting {
shoule be:
public event GridViewUpdateEventHandler RowInserting {

I also made a slight change to better handle utilizing template columns for
the command columns.

Well, I should have guessed. I think it's my frustration. So good it's
almost Friday.

Hi Tomasz,

You could use GridView's EmptyDataTemplate to display a message to user
that the GridView doesn't have any data available:

<EmptyDataTemplate>
There is no data.
</EmptyDataTemplate>


However, it will not show the header or footer. As a workaround, you could
use following class:

#10,000 Monkeys - Harnessing The Power of Typing Monkeys : Displaying
GridView When No Data Exists
http://blogs.claritycon.com/blogs/ke...02/28/247.aspx


You could use this class instead of GridView where is needed; or use
following config to automatically replace all GridView with EmptyGridView
without changing your existing WebForms:

<system.web>
<pages>
<tagMapping>
<!-- assume you added EmptyGridView to App_Code folder within namespace
"myns" -->
<add tagType="System.Web.UI.WebControls.GridView"
mappedTagType="myns.EmptyGridView,App_Code"/>
</tagMapping>
</pages>
</system.web>

If its not appropriate, you could probably just check the recordcount of the
datatable before you bind, and if its zero bind to a manually created
datatable containing a single record of spaces. That will render your
header and footer.
