I have a hidden (primary key) object in my GridView:

<asp:HiddenField ID="hidRemUUID" runat="server" Value='<%# Eval("MyUUID")
%>' />


Now, there is a more elegant way to keep track of the primary key... with a
GridView.



You might want to look into this also:
DataKeyNames="MyUUID" (this is declared in the <asp:GridView> element.



Then you can get to it like this:


protected void GridView1_SelectedIndexChanged(object sender, EventArgs
e)
{


GridView gv = (GridView)sender;

//string str0 = gv.DataKeyNames[0];

System.Guid uuid = (System.Guid)gv.DataKeys[gv.SelectedIndex].Value;

// or
//string uuid = (string)gv.DataKeys[gv.SelectedIndex].Value; //


}

For some reason, why does ASP.net only see variables that are 'DISPLAYED'
inside a datagrid?

Even if the Field is Databound, I cannot post the variable or use it in an
updatecommand... it has to be visible??


I've tried putting the field on the page but making 'Visible = false' but it
still dosen't want to post or anything.


Is it a bug in Visual Web Developer 2005?


Cheers

Sorry, I meant Gridview

I had a similar issue, i wanted to hide the autonumberfield.
Afaik i used a hidden div enclosing the item in a template.
If you really need to know, let me know, i have to look it up.
