I have two drop down lists. I want to dynamically change the option values in one list based on a selection in the other list.

Can someone get me started on how to do this?

I had planned to pull the data from tables, though at this point the list boxes are hard coded. I can live with them being hard coded.

Here is part of the form code I'm using with the tables. I want to make a selection in the jobboard list and auto populate the categories list box.

I do have MS SQL tables with the data for each of the list boxes, so if it is easier to grab the data fram a table and do it or easier to hard code the options I would prefer, at this point, to do whichever is easier.

Code: 
<td><asp:DropDownList id="category" runat="server">
   <asp:ListItem value="21">customer s.</asp:ListItem>
   <asp:ListItem value="22">restaurant</asp:ListItem>
   <asp:ListItem value="23">marketing</asp:ListItem>
   <asp:ListItem value="24">management</asp:ListItem>
   <asp:ListItem value="25">arts</asp:ListItem>
   <asp:ListItem value="26">banking</asp:ListItem>
   <asp:ListItem value="27">retail</asp:ListItem>
   <asp:ListItem value="28">sales</asp:ListItem>
   <asp:ListItem value="29">adv</asp:ListItem>
   <asp:ListItem value="30">clerical</asp:ListItem>	
</asp:DropDownList></td>
<td><asp:DropDownList id="jobboard" runat="server">
   <asp:ListItem value="1">Monster</asp:ListItem>
   <asp:ListItem value="2">HotJobs</asp:ListItem>
</asp:DropDownList></td>

Just in case, here is all the code I'm using so far.

All you need to do is use the SelectedIndexChanged event of the first dropdownlist to get it's value and populate the second list accordingly.

Here is how I ended up doing it.

Code: 
   Sub page_load(sender as Object, e as EventArgs)

    if NOT IsPostBack() then	 
	 
        Dim myConnection1 As New SqlConnection(ConnectionString)
				
				Dim getJobBoard As String = "SELECT job_board_id, job_board from job_board"
				
				Dim jda as New SqlDataAdapter(getJobBoard, myConnection1)
               
        Dim DS As New DataSet
				
        myConnection1.Open()
				
        jda.Fill(DS)
				
        myConnection1.Close()
				
        jobboard.DataSource = DS.Tables(0)
        jobboard.DataTextField = "job_board"
        jobboard.DataValueField = "job_board_id"
        jobboard.DataBind()


    end if
				
    end sub		
		
		
		sub Category_SelectedIndexChanged(sender as Object, e as EventArgs)		
		
        Dim myConnection2 As New SqlConnection(ConnectionString)
				
				Dim getCategory As String = "SELECT category_id, category from categories where job_board_id = '" + jobboard.SelectedItem.Value + "'"
				
				Dim cda as New SqlDataAdapter(getCategory, myConnection2)
               
        Dim CS As New DataSet
				
        myConnection2.Open()
				
        cda.Fill(CS)
				
        myConnection2.Close()
				
        category.DataSource = CS.Tables(0)
        category.DataTextField = "category"
        category.DataValueField = "category_id"
        category.DataBind()		


		end sub

The list box code.

Code: 
<td><asp:DropDownList id="jobboard" runat="server" Rows="1" EnableViewState="True"  autopostback
onSelectedIndexChanged="Category_SelectedIndexChanged" 
DataTextField="job_board" DataValueField="job_board_id">
</asp:DropDownList></td>
<td><asp:DropDownList id="category" runat="server"  EnableViewState="True"></asp:DropDownList></td>

Any suggestions on improving this?
