Question

I have a website where the user requires to add and remove Headlines from the main page. The headlines are stored in a database with a column titled ‘Display’ (true or false) which decides if the headlines appear. I want the user to have the ability to add or remove headlines from the main page, so have created another page which creates a table of all headlines along with a drop down list containing ‘Enable’ and ‘disable’. I want these drop down lists to work by when the user changes the value in the drop down list the database will be updated. Only I cant find how to give the drop down lists an on change event.

Any ideas? Am I going about this the right way or is there a better way to do this?

Answer 1

First, to do your actual request You would set the dropdowns to autopostback, and add a handler to get the value and update the data, IE (although at minimum your dropdowns would be in a repeater, or datagrid)

    Private Sub SetupDropdowns()         Dim pDropDown As New DropDownList         pDropDown.Items.Add('Yes')         pDropDown.Items.Add('No')         pDropDown.AutoPostBack = True         AddHandler pDropDown.SelectedIndexChanged, AddressOf pDropDown_SelectedIndexChanged     End Sub      Private Sub pDropDown_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)         Dim value As String = CType(sender, DropDownList).SelectedValue 'Do something with value     End Sub 

An easier way, if you are accessing SQL directly is to use a datagrid and databind it to your SQL query.
