Frustrating dropdownlist problem!!

[greg_quinn]

I am rendering a dropdownlist to a page dynamically in Page_INIT... i.e

Dim typeDropDown As New DropDownList

typeDropDown.ID = "typeDropDown1"
typeDropDown.DataValueField = "ItemID"
typeDropDown.DataTextField = "ItemName"

Page.Controls.Add(typeDropDown)

I then bind my data to the dropdownlist...

PopulateDropdown(typeDropDown, objDataReader("datatable").ToString())

Now in Page_Load(), I need to set the selected item in the dropdown from the database.

But setting it manually, using

Dim typeDropDown As New DropDownList

typeDropDown = Page.FindControl("typeDropDown1")
typeDropDown.Items.FindByText("Choice 2").Selected = True

Gives me the error...

A dropdownlist cannot have multiple items selected!!!

Now why is this happening? I am only setting the selected item the first time in Page_Load(), there are no postbacks or anything on the page. This doesn't make any sense to me. Please help!!!

Ok, this is fixed, quite strange fix though.

Instead of binding to the dropdown in Page_Init, (as I have always done), I moved the binding to Page_Load() in the same routine where the listitem is selected.
