Event Handling Problem

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

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

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

VB Code:

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

at the top of your page

Hello

Event Handling problem has been solved. Anyhow it is working fine now.

Thanks
