Setting ListBox1.selectedindex to match a variable.

[gmack]

I have poked around the web and forums and found no help.
I have tried a couple of different ways in code but no joy on a solution to my prob.

Here is it, I present the user with a ListBox1 of all "reporting periods" for the year to select from but I would like the the "current" period to be the selected index so the user can just click "SELECT" or select a differnet and click select.

The Current period is stored in a Public Variable (CurrReportPeroidKey)

the listbox has all the periods listed
DisplayText = Period Description
SelectedValue = ReportPeriodKey

I would like to do somethinglike,

Set listbox1.selectedindex where listbox1.value = currReportPeriodKey.
Is there there a way to sift through the all the values in the listbox and find the index that matches the value to my stored variable value?

the listbox1 is populated via a database table of period.

I tried something like this..

For Each Item In ListBox1.SelectedValue
If Item.ListBox1.SelectedValue = CurrReportPeroidKey Then
LBindex = Item.ListBox1.SelectedIndex

End If

Next

Loop through your items and check if the item matches your variable. Here is a quick example I whipped up:

        'My listbox items are:
        '1
        '2
        '3
        '4
        'Etc.
        Dim fooVariable As String = "4"
        For i As Integer = 0 To ListBox1.Items.Count - 1
            If ListBox1.Items(i).ToString = fooVariable Then
                ListBox1.SelectedIndex = i
            End If
        Next

Thanks,
doesnt seem to work.
gives system.data.rowview as the value.

You have it bound. That makes it slightly more difficult, since your items are DataRowViews, so what you will have to do is something more like this:

If DirectCast(ListBox1.Items(i),DataRowView)("SomeField").ToString = fooVariable Then

The SomeField is whatever field you are displaying, or whatever field you want to compare to fooVariable.
