ComboBox + DropDownList

obrienkev · October 31st, 2007, 10:50 AM

Hi,

I have a ComboBox set to DropDownList to prevent users from typing in data.

The ComboBox is binded to a dataset.

I want the first option to display automatically on the ComboBox as "Select an Option"

How do I do this?

Thanks.

comboBox.Items.Insert(0, "Select an Option");

Get this error...

Items collection cannot be modified when the DataSource property is set

Ah, right, apologies. In that case you're probably have to resort to adding the value to your datasource.

I had the same problem a while a go. I resolved it by creating a distinct query on the field i want to populate. And the reslut of that query filled my items Collection. After this procedure ive added the Select an Option Like Samjudson told you.
