Adding List Item Programmatically

Hi All

I wonder if you can help. Within a Page_Load event I would like to be able to add a List item to a dropdown control within my page. I thought that it would be the following syntax but doesn't like it:

Code:

MyDropdownList.DataTextField.Insert = "ALL"
MyDropdownList.DataValueField.Insert = "%"

Am I way out?

Yeah, you're way out... ;)

DataTextField and DataValueField are properties that hold the name of a column / property of the data collection you're bind the control to. So, if you have a DataTable with an Id and a Description column for example, DataTextField would be "Description" and DataValueField would be "Id".

To add items, you can either add them in the markup of the page, or use the Add or the Insert method of the Items collection of the drop-down control. The latter allows you to specify the position of the item in the list.

Code:

MyDropdownList.Items.Add(new ListItem("text", "value"));
MyDropdownList.Items.Insert(4, new ListItem("text", "value"));

HtH,
