I am trying to search a list box by adding a text box next to it.
in the textbox_textchanged I added below code
'Retrieve the item's listindex
Dim i As Integer = List1.FindString(Text1.Text)
'highligting the matched ones
List1.SelectedIndex = i
But I am getting Below error
Error 1 'FindString' is not a member of 'System.Web.UI.WebControls.ListBox'
How can I resolve this?
