Hi,

Does anybody know if it is possible to have a DataGrid display itself
(atleast a header) although it does not contain any data? I suppose I =
have
to write my own control, have it inherit the DataGrid, and do some =
trick
when rendering, right?

Thanks in advance,

It's easier than that -- no need to create a derived control. You just =
need to bind the grid. If the datasource exists but contains no =
items/rows and ShowHeader=3Dtrue (that's the default), you'll see just =
the header. I also usually add a "no records found" item to the grid so =
that it's not just a header by hooking the grid's OnItemCreated event =
and showing this message in the footer:

// handles OnItemCreated for my DataGrid

void CheckGridEmpty(object sender, DataGridItemEventArgs e) {

// buff up the presentation a bit if the grid is empty
if (e.Item.ItemType =3D=3D ListItemType.Footer) {
=20
// add a message in the footer if there are no items
DataGrid dg =3D (DataGrid)sender;
int count =3D dg.Items.Count;
if (count =3D=3D 0) {
dg.ShowFooter =3D true;
e.Item.Cells[0].Text =3D "No items found.";
}
else {=20
dg.ShowFooter =3D false;
}
}
}

I guess what you want is a default behavior ... Even if you don't have
any data .. the datagrid is shown (my examples work without data ..)
