Opening RadWindow from RadWindow and onClientClose event

Hi all,

I have an aspx page with a windowmanager which contains 2 separate windows (window1 and window2). Window 2 is a lookup dialogue form containing values which the user can select to return values to the parent window. Both Windows can be opened directly from the aspx page.

Window2 can also be opened from Window1. Originally I put a new windowmanager in Window1 but I realised that this was not correct because when window2 was opened from window1, it opened inside window1 (and was only partially visible and restricted to window 1's borders) which is not correct. So as per the documentation (http://www.telerik.com/help/aspnet-ajax/window-programming-opening-from-within-dialog.html) I use the aspx forms window manager to open window2 from window1.

My problem is that I am using the onClientClose event for window2 to populate the aspx page with return values from window2. However I also need to populate window1 with return values from window2 when window2 is called from window1.

Does anybody know how I can (and should) achieve this?

Many Thanks

Mark

Grid Insert Refresh other control

I am not sure this should actually be here in Grid or Ajax manager. I have a Grid and an Ajax manager control. I insert into the grid and, as expected, the whole page does not refresh yet the grid does. (Very Nice).

Now I have run into an issue where I have had to add a SQLDataSource and FormView on the page that needs to be updated after the insert into the Grid. I can force the page to refresh and have the FormView update but this sort of defeats the purpose of using the Ajax control to prevent a full page refresh.

I have tried to have the SQLDataSource and FormView refresh using both the Gridss ItemInserted and/or the Grid's SQLDataSource Inserted to force a rebind of the FormView. Niether worked.

Is there a way to have the FormView rebind/refresh after the Grid Insert has occured?

Here is my AJAX code:

<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">

<script type="text/javascript" language="javascript">

function refreshGrid(arg) {

if (!arg) {

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest("Rebind");

}

</script>

</telerik:RadCodeBlock>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadCodeBlock1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="rgd_Labor" UpdatePanelHeight="" />

<telerik:AjaxUpdatedControl ControlID="rgd_Materials" UpdatePanelHeight="" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Aggregate Sum Function in footer with paging

Hi,
Am using Footer in Rad Grid for summing up my total column.
Now the total is showing for the entire datasource which i set for that grid.
All i needed is to display the summation , for the current page records alone (say for the current 10 records if i set to pagesize as 10).
Is there any way to implement this feature ?

Regards,
Karthikeyan G

[Solved] Remove/hide child nodes?

I have a project with 2 types of users. I want only the Supervisors to be able to view the "User Management" page. This page is a child node of my rad menu and it seems that I can only hide the title node or I get this error:

"Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index"

How do I hide just some of the pages in the child nodes?

    <siteMapNode title="Users" roles="Supervisor" target="_blank">
        <siteMapNode url="UsersOnline.aspx" title="Users Online" target="_blank" />
        <siteMapNode url="UserManagement.aspx" title="User Management" target="_blank" />
    </siteMapNode>

Protected Sub RadMenu1_ItemDataBound(ByVal sender As Object, ByVal e As Telerik.Web.UI.RadMenuEventArgs) Handles RadMenu1.ItemDataBound
Dim node As SiteMapNode = TryCast(e.Item.DataItem, SiteMapNode)

        If Not String.IsNullOrEmpty(node("target")) Then
            e.Item.Target = node("target")
        End If
        If e.Item.Text = "User Management" AndAlso msUserType = "Standard" Then
            RadMenu1.Items.Remove(e.Item)
        End If
    End Sub

                </telerik:RadGrid>

Now, heres where it works and doesn't. If I have this line (similar for the second drop down):

    
             <asp:DropDownList ID="cmbEdit_Enabled" runat="server" Width="119px" SelectedValue='<%# Bind("Enabled") %>'>  
        
                                                <asp:ListItem Value="True">Yes</asp:ListItem> 
        
                                                <asp:ListItem Value="False">No</asp:ListItem> 
        
                                            </asp:DropDownList>

when I go into edit mode, the drop downs are populated with the current values which is a project requirement. But when I click the 'Add new user', I get this error:

'cmbEdit_Rights' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value

If I leave out the <%# Bind("UserLevel") %> I can insert and update, but I loose the requirement of displaying the current value which I need.

Please help asap!

[Solved] Hiding RadDataPager when there is only one page

Hello there,

I have a RadListView displaying data in pages of 4 using the RadDataPager:

                                  <telerik:RadDataPager ID="UnlocatedCasesPager"          
                                                                  runat="server"          
                                                                  PagedControlID="UnlocatedCasesListView"          
                                                                  PageSize="4">         
                                                <Fields>         
                                                    <telerik:RadDataPagerButtonField FieldType="FirstPrev" />         
                                                    <telerik:RadDataPagerButtonField FieldType="Numeric" PageButtonCount="3" />         
                                                    <telerik:RadDataPagerButtonField FieldType="NextLast" />         
                                                </Fields>         
                                            </telerik:RadDataPager>         

I cannot work out how to hide the pager when there are 4 or less items being displayed in my list view. I have tried using the FindControl method of the ListView to get hold of the pager and hide it if necessary in various places (OnDataBound event and when I actually assign the datasource of the ListView) but that always returns null. The pager is contained in the <LayoutTemplate>.

Thanks very much, Carl
