Searching for a ListItem Client Side

[Robert Bross]

Does anyone know how to do this? I looked through the docs and forums and could only find information on selecting the "first" item. The reason I need this is I have a certain item selected by handling the onclick event of the item within the <ItemTemplate>. However, after a postback I need to be able to reselect the item again. Any help or advise would be greatly appreciated! Thanks!

Hi Robert,

As RadListView is a look-less control and does not have any built-in layout, there is no notion of item client-side object. However you can use the server-side RadListViewDataItem's DisplayIndex  to trigger client-side selectItem method, similar to the following:

<telerik:RadListView runat="server" ID="RadListView1"
        OnNeedDataSource="RadListView1_NeedDataSource">
        <ItemTemplate>
            <input type="button" value="click me to select" onclick='selectItem(<%#Container.DisplayIndex %>)' />
        </ItemTemplate>
        <SelectedItemTemplate>
            selected
        </SelectedItemTemplate>
    </telerik:RadListView>
    <script type="text/javascript">
        function selectItem(displayIndex) {
            $find("<%=RadListView1.ClientID %>").selectItem(displayIndex);
        }
    </script>

All the best,
