| GOOD ANSWER |
I've created a hashtable and bound a control to it:
protected void Page_Load(object sender, System.EventArgs e)
{
if (! Page.IsPostBack)
{
Hashtable hashPeople = new
Hashtable();
hashPeople.Add ("John", 1);
hashPeople.Add ("Paul", 3);
hashPeople.Add ("George", 5);
hashPeople.Add ("Ringo", 7);
hashPeople.Add ("Fred", 11);
hPeople.DataSource = hashPeople;
dList.DataBind();
}
}
When I attempt to bind to a DataList control with the following code:
<asp:DataList ID="dList" Runat="server"
OnItemCommand="ExecuteService" AlternatingItemStyle-BackColor="#cccc99">
<HeaderTemplate>
<b>Some Horoscopes</b>
</HeaderTemplate>
<ItemTemplate>
'<%# Container.DataItem.Key %>'
</ItemTemplate>
</asp:DataList>
I get the error:
Compiler Error Message: CS0117: 'object' does not contain a definition
for 'Key'
What am I missing?
cheers

shouldn't this...
hPeople.DataSource = hashPeople;
dList.DataBind();
be more like this...
dList.DataSource = hashPeople;
dList.DataBind();

In fact, it is. For some reason I amended the email code before I sent
it out.
So it is as you say it is (otherwise it wouldn't have compiled), but I
am still getting this error with the line at:
'<%# Container.DataItem.Key %>'

Faisal,
In C# (not in VB.NET), you need to do a bit of casting because ASP.NET
does not know the data type of Container.DataItem. For example:
[VB]
<%# Container.DataItem.Key %>
[C#]
<%# ((DictionaryEntry)Container.DataItem).Key %>
