How to get select item index in listview without clicking button?

May 05, 2009 01:11 PM|LINK

I would like to get the selected item index when user click the row in ListView. In MSDN, I just find, it needs to add a "Select" button for every row. How to select the row without button,just click the row.

Hi freshare ,

see my solution.

        protected void ListView1_ItemDataBound(object sender, ListViewItemEventArgs e)
        {
            if (e.Item.ItemType == ListViewItemType.DataItem)
            {
                Button btn = e.Item.FindControl("Button1") as Button;
                string script = this.ClientScript.GetPostBackClientHyperlink(btn,"",true);
                Panel p = e.Item.FindControl("Panel1") as Panel;
                p.Attributes.Add("onclick",script);
            }
        }

        protected void ListView1_SelectedIndexChanging(object sender, ListViewSelectEventArgs e)
        {

        }

<asp:ListView ID="ListView1" runat="server" DataKeyNames="id"
        DataSourceID="SqlDataSource1" onitemdatabound="ListView1_ItemDataBound"
        onselectedindexchanging="ListView1_SelectedIndexChanging">

        <LayoutTemplate>
            <table runat="server">
                <tr runat="server">
                    <td runat="server">
                        <table ID="itemPlaceholderContainer" runat="server" border="0" style="">
                            <tr runat="server" style="">
                                <th runat="server">
                                    id</th>
                                <th runat="server">
                                    approved</th>
                            </tr>
                            <tr ID="itemPlaceholder" runat="server">
                            </tr>

                <tr runat="server">
                    <td runat="server" style="">
                    </td>
                </tr>
            </table>
        </LayoutTemplate>

        <SelectedItemTemplate>

                </td>
            </tr>
        </SelectedItemTemplate>
        <EmptyDataTemplate>

                </tr>
            </table>
        </EmptyDataTemplate>
