Event Handling Problem

[mahesh_575]

Hello

I am having 2 combo boxes (dropdownlists) on ASPX Page. If value is changed in first dropdownlist, values in 2nd dropdownlist should be changed accordingly. For this I am trying to write Event Handling Code.

But it is giving me error

Compiler Error Message: BC30506: Handles clause requires a WithEvents variable.

Code is as follows :

Sub ddlChiiki_SelectedIndexChanged(sender As Object, e As EventArgs) Handles ddlChiiki.SelectedIndexChanged
Dim AL as ArrayList = new ArrayList()
Dim Temp1, Temp2 as string
If File.Exists(csvPath & sCSVFileName) = True Then
Try
' Open the file to read from.
sr = File.OpenText(csvPath & sCSVFileName)
sr.ReadLine()
Do While sr.Peek() >= 0
Dim txtTemp=Split(sr.ReadLine(), txtDelimiter)
Temp1 = txtTemp(1)
Temp2 = txtTemp(3)
If ddlChiiki.SelectedItem.Text = Temp1 Then
AL.Add(Temp2)
End If
Loop
sr.Close()

ddlPam1.DataSource = AL
ddlPam1.DataBind()

Catch x As Exception
Response.Write(x.ToString())
End Try
End If
End Sub

<aspropDownList id="ddlChiiki" runat="server" OnSelectedIndexChanged="ddlChiiki_SelectedIndexChanged" AutoPostBack="True" Width="120px"></aspropDownList>

Pls suggest something earliest.

[What is exact meaning of Handles, AddHandler, etc. ?]

Thanks

Are you using Code Behind or script blocks on your page?

You should have something like this

Inherits System.Web.UI.Page
Protected WithEvents ddlChiiki As System.Web.UI.WebControls.DropDownList

at the top of your page
