How to pre-set combo textbox's selectedindex value from querystring passed
from another page?

I pass the querystring to set combo text box (change selectedindex on
Page_Init).
Source code as:

Protected Sub Page_Init(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Me.Init
If Not (Page.IsPostBack) Then
If Not String.IsNullOrEmpty(Request.QueryString("RptType" )) Then
Dim rptType As String =
Request.QueryString("RptType").ToString
Select Case rptType
Case "Invoice"
ReportTypeCombo.SelectedIndex = 0
Session("RptType") = "Invoice"
Case "P.O."
ReportTypeCombo.SelectedIndex = 1
Session("RptType") = "P.O."
Case "Contract"
ReportTypeCombo.SelectedIndex = 2
Session("RptType") = "Contract"
End Select
End If
End If
End Sub

When I run it, it don't work. What is my wrong?

Make sure that code runs AFTER you populate the combo box

Hi,
Chech the same code by moving that code block from Page_Init to
Page_Load....
