[Solved] Why does get_dataItem() evaluate to null?

    <script type="text/javascript">
        function docFileGridOnRowCreated(sender, eventArgs) { }
        function docFileGridOnRowCreating(sender, eventArgs) { }

        function docFileGridOnRowDblClick(sender, eventArgs)
        {
            alert(eventArgs.get_gridDataItem().get_dataItem());
        }
    </script>
    <style type="text/css">
    </style>


    <asp:Button ID="btn" runat="server" Text="Save" />
    <cym:RadGrid ID="docFileGrid" runat="server" DataSourceID="docFileODS"
        ClientSettings-ClientEvents-OnRowDblClick="">
        <ClientSettings>
            <ClientEvents OnRowCreated="docFileGridOnRowCreated"
                OnRowCreating="docFileGridOnRowCreating" OnRowDblClick="docFileGridOnRowDblClick" />
        </ClientSettings>
        <MasterTableView DataKeyNames="AccountFileID, AccountID, FileID, GUID">
            <Columns>
                <rad:GridBoundColumn DataField="FileName" HeaderText="Name" />
        </MasterTableView>
    </cym:RadGrid>

I've subscribed to the OnRowCreated/OnRowCreating event as per the documentation's instructions; however, get get_dataItem() and get_dataKeyValue() methods return null.  What am I doing wrong?

Hello,

The method eventArgs.get_gridDataItem() will return the corresponding dataitem in 'OnRowDblClick' event handler. Then calling the getDataKeyValue() method of dataitem will return key value. Also set the ClientDataKeyNames accordingly.

aspx:

    <cym:RadGrid ID="docFileGrid" runat="server" DataSourceID="docFileODS">
        <ClientSettings>
            <ClientEvents OnRowCreated="docFileGridOnRowCreated"
                OnRowCreating="docFileGridOnRowCreating" OnRowDblClick="docFileGridOnRowDblClick" />
        </ClientSettings>
        <MasterTableView ClientDataKeyNames="FileName" DataKeyNames="AccountFileID, AccountID, FileID, GUID">
            <Columns>
                <rad:GridBoundColumn DataField="FileName" HeaderText="Name" />
            </Columns>
        </MasterTableView>
    </cym:RadGrid>

javascript:

    function docFileGridOnRowCreated(sender, eventArgs) { }
    function docFileGridOnRowCreating(sender, eventArgs) { }

    function docFileGridOnRowDblClick(sender, eventArgs) {
        alert(eventArgs.get_gridDataItem());
        alert(eventArgs.get_gridDataItem().getDataKeyValue("FileName"));
    }
