I have a listbox called lbConds.

it contains 4 items.

1
2
3
4

the selection mode is multiple

When I select the items and submit the page I can't seem to trap which items where selected...

this is what I'm doing...

C#....

protected void btnPreview_Click(object sender, EventArgs e) {
ListItemCollection myConds = null;
        int[] selectedConds = lbCond.GetSelectedIndices();
        if (lbCond.GetSelectedIndices().Length > 0) {
            for (int i = 0; i < selectedConds.Length; i++) {
                myConds.Add(lbCond.Items[selectedConds[i]]);
            }
        }
}


ASP.NET

<asp:Button id="btnPreview" CausesValidation="False" runat="server" style="z-index: 107; left: 237px; position: absolute;
            top: 550px; width: 130px;" width="100px" OnClick="btnPreview_Click" />

<asp:ListBox ID="lbCond" runat="server" DataTextField="CondText" DataValueField="EnglishID"
            Height="193px" SelectionMode="Multiple" Style="z-index: 122; left: 238px; position: absolute;
            top: 272px"></asp:ListBox>

Thanks!
