I have a combo box server control. I would like to databind it to one of my
methods. However, I would also like to add "Please Select" with a null value
to the box. What is the best way to do this?

Here is my code:

With cboStatusCode
.DataSource = oEstimate.GetAllEstimateStatusCode
.DataValueField = "ID"
.DataTextField = "Name"
.DataBind()
End With

If I try to add .Items.Add("Please Select") it doesn't work, unless I add it
after the databind which makes sense. Unfortunately, if I do that, it shows
up as the last item in the drop down, and I want it as the first. Is it not
possible to add a "Please Select" using databind if you want it to be the
first item in your combo box? (I realize I could do a for loop in the code
and use the .items.add for each item in my datatable returned by the method
which is the datasource, but that makes things messier)

Thanks,
Greg

With cboStatusCode
.DataSource = oEstimate.GetAllEstimateStatusCode
.DataValueField = "ID"
.DataTextField = "Name"
.DataBind()
.Items.Insert(0, New ListItem("Please Select", "0"))
End With
