Two .ascx controls

[Zed]

Hello,
   I have 2 radgrids, each one inside a .ascx control.  Each control is inside a RadPageView on the same .aspx page.  When I delete a record from one radgrid, I need the other one to refresh with the correct information.  (basically parent child relation between the two grids)  How can I update the datasource on the child radgrid?

Thanks

Hi Zed,

I guess you are having difficulty in accessing the RadGrid from the UserControl which is in the other PageView. If so you may try the sample code which I tried on my end.

ASPX:

   <telerik:RadTabStrip ID="RadTabStrip1" runat="server" MultiPageID="RadMultiPage1" >
                  <Tabs>
                    <telerik:RadTab Text="Tab1" PageViewID="RadPageView1" ></telerik:RadTab>
                     <telerik:RadTab Text="Tab2" PageViewID="RadPageView2"  ></telerik:RadTab>
                  </Tabs>
                </telerik:RadTabStrip>

                <br />
                <telerik:RadMultiPage ID="RadMultiPage1" runat="server">
                        <telerik:RadPageView ID="RadPageView1" runat="server" Width="100%">
                    &nbsp;<uc2:Order id="Order1" runat="server"></uc2:Order>

                    </telerik:RadPageView>
                <telerik:RadPageView ID="RadPageView2"  runat="server" Width="100%">
                    &nbsp;<uc3:OrderDetails id="OrderDetails1" runat="server"></uc3:OrderDetails>
                    </telerik:RadPageView>
                </telerik:RadMultiPage><br />

Orders.ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="Order.ascx.cs"
    Inherits="Order" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthWindConnectionString %>"
    SelectCommand="SELECT [OrderID], [ProductID], [UnitPrice] FROM [OrderDetails]"></asp:SqlDataSource>
<telerik:RadGrid ID="OrderGrid" runat="server" AutoGenerateEditColumn="true" DataSourceID="SqlDataSource1" AllowPaging="true" PageSize="5" GridLines="None" OnDeleteCommand="OrderGrid_DeleteCommand" >
    <MasterTableView CellSpacing="-1" DataSourceID="SqlDataSource1">
        <Columns>
          <telerik:GridButtonColumn CommandName="Delete" Text="Delete" ></telerik:GridButtonColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

OrderDetail.ascx:

<%@ Control Language="C#" AutoEventWireup="true" CodeFile="OrderDetails.ascx.cs" Inherits="OrderDetails" %>
<%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>

<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:NorthWindConnectionString %>"
    SelectCommand="SELECT [OrderID], [CustomerID], [EmployeeID] FROM [Orders]"></asp:SqlDataSource>
<telerik:RadGrid ID="DetailsGrid" runat="server" AutoGenerateEditColumn="true"  DataSourceID="SqlDataSource1" AllowPaging="true" PageSize="5" GridLines="None">
    <MasterTableView CellSpacing="-1" DataSourceID="SqlDataSource1">
        <Columns>
         <telerik:GridButtonColumn CommandName="Delete" Text="Delete"  ></telerik:GridButtonColumn>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Order.ascx.cs:

 protected void OrderGrid_DeleteCommand(object source, Telerik.Web.UI.GridCommandEventArgs e)
    {
        //Delete Query

        // to access the Grid in the other usercontrol which is in the other PageView
        RadGrid detailsGrid = (RadGrid)this.Page.FindControl("OrderDetails1").FindControl("DetailsGrid");
     // update the detailsGrid data
        detailsGrid.MasterTableView.Rebind();

    }

Thanks

I found a better way that is not as complicated using a delegate and then subscribing to the update event.
