I have a radbutton in ItemTemplate of RadListView. I have defined  ClientDataKeyNames="ID" 
Now how do I get the  ClientDataKeyValue "ID" onClientClicked of radbutton? Is it possible to get the index of the ListviewITem on clientside javascript? 

Thanks in advance.

Hi Chetan,

Please try the following code snippet get the ClientDataKeyValues of a RadListView on RabButton OnClientClicked event.

ASPX:

<telerik:RadListView ID="RadListView1" Width="97%" AllowPaging="True" runat="server"
    AllowSorting="true" DataSourceID="SqlDataSource1" ItemPlaceholderID="ProductsHolder"
    DataKeyNames="ProductID" ClientDataKeyNames="ProductID" OnItemDataBound="RadListView1_ItemDataBound">
    <LayoutTemplate>
        <fieldset style="max-width: 920px;" id="FieldSet1">
            <legend>Products</legend>
            <asp:Panel ID="ProductsHolder" runat="server" />
        </fieldset>
    </LayoutTemplate>
    <ItemTemplate>
        <telerik:RadButton ID="RadButton1" runat="server" Text="Demo" OnClientClicked="OnClientClicked1">
        </telerik:RadButton>
    </ItemTemplate>
</telerik:RadListView>

C#:

protected void RadListView1_ItemDataBound(object sender, Telerik.Web.UI.RadListViewItemEventArgs e)
{
    if (e.Item is RadListViewDataItem)
    {
        RadListViewDataItem item = e.Item as RadListViewDataItem;
        RadButton btn = item.FindControl("RadButton1") as RadButton;
        btn.Attributes.Add("rowindex", item.DataItemIndex.ToString());
    }
}

JavaScript:

<script type="text/javascript">
    function OnClientClicked1(sender, args) {
        var listview = $find("<%=RadListView1.ClientID %>");
        var index = sender._element.getAttribute("rowindex");
        alert(listview._clientKeyValues[index].ProductID);
    }
</script>

Hope this will helps you.
Thanks,
Shinu.
