    Hello Mitesh,

    In order to implement the functionality you described you have to set EnableAjax property of the grid to “false" and set Auto post back flag for Row Selection. Below is markup of grid and label in two different update panels.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server">
    <ContentTemplate>
    <ig:WebDataGrid ID="WebDataGrid1" runat="server" Height="350px" EnableAjax="false"
    AutoGenerateColumns="False" Width="627px" DataKeyFields="Cutomer Id" OnRowSelectionChanged="WebHierarchicalDataGrid1_RowSelectionChanged">
    <Columns>
    <ig:BoundDataField DataFieldName="Cutomer Id" Key="Cutomer Id">
    <Header Text="Cutomer Id"></Header>
    </ig:BoundDataField>
    <ig:BoundDataField DataFieldName="Address" Key="Address">
    <Header Text="Address"></Header>
    </ig:BoundDataField>
    </Columns>
    <Behaviors>
    <ig:Selection RowSelectType="Single" Enabled="true" CellSelectType="Multiple" CellClickAction="Row">
    <AutoPostBackFlags RowSelectionChanged="True" />
    </ig:Selection>
    </Behaviors>
    </ig:WebDataGrid>
    </ContentTemplate>
    </asp:UpdatePanel>

    <asp:UpdatePanel ID="UpdatePanel2" runat="server">
    <ContentTemplate>
    <asp:Label ID="Label2" runat="server" Text="Label"></asp:Label>
    </ContentTemplate>
    </asp:UpdatePanel>

    Below lines of code updates label text based on the cell selected in current row:

    protected void WebDataGrid1_RowSelectionChanged(object sender, Infragistics.Web.UI.GridControls.SelectedRowEventArgs e)
    {
    if (e.CurrentSelectedRows != null)
    {
    string seltext = e.CurrentSelectedRows[0].Items[0].Text;
    Label2.Text = seltext;
    }
    }

    Hope this helps.
