I have been able to create and populate dropdowns in both the item template
tag and the edit template tag. When I try to add one to the footer the
function I have inserted into the datasource tag never gets called. What is
the proper way to populate a dropdown in the Footer Template of a DataGrid?

Thanks
Ed

in your itemdatabound eventhandler, are you checking if the cell is of type
footer?

First I Just tried calling a function from the HTML code in the datasource
tag of the list box (The function GetAgencies returns a datatable, and the
following code works great in an edittemplate tag):

<FooterTemplate>
<aspropDownList runat="server" lstAddAgencies"
DataValueField="Code" DataTextField="Description" DataSource="<%#
GetAgencies() %>"></aspropDownList>
</FooterTemplate>

I then tried the following code:

Sub C1WebGrid2_ItemDataBound(ByVal sender As Object, ByVal e As
C1.Web.C1WebGrid.C1ItemEventArgs) Handles C1WebGrid2.ItemDataBound
If e.Item.ItemType = C1.Web.C1WebGrid.C1ListItemType.Footer Then
lstAddAgencies.DataSource = GetAgencies()
lstAddAgencies.DataBind()
lstAddNames.DataSource = GetNames()
lstAddNames.DataBind()
End If
End Sub

Neither of the above methods will populate the dropdowns in the footer.

for your last function you will need to set the datatextstring property to
the value of the column you want to display otherwise it won't show

This code works for me:

protected override void OnLoad(EventArgs e)
{
System.Collections.ArrayList list = new System.Collections.ArrayList();
list.Add("hi");
list.Add("there");
DG.DataSource = list;
DG.DataBind();
}

protected System.Data.DataTable GetAgencies()
{
System.Data.DataTable t = new System.Data.DataTable();
t.Columns.Add("code");
t.Columns.Add("description");
System.Data.DataRow row = t.NewRow();
row["code"] = "1";
row["description"] = "one";
t.Rows.Add(row);
row = t.NewRow();
row["code"] = "2";
row["description"] = "two";
t.Rows.Add(row);
return t;
}
</script>

I think it is just a problem with the component one datagrid I am using, because it works fine with the regular datagrid control. Thanks for the help.
