Using the RadAjaxManagerProxy inside a WebUserControl

Hi, I'm populating a page dynamically with usercontrols, the user control is loaded without problem but the ajaxrequest or a simple postback inside the user conteol is not working..

This is an simple exsample....what's wrong with that?

ASPX:

    
                    <asp:ScriptManager ID="ScriptManager1" runat="server">  
        
                    </asp:ScriptManager> 
        
                    <asp:Button ID="Button1" runat="server" Text="Button" /> 
        
                    <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label> 
        
                    <asp:Button ID="Button2" runat="server" Text="Load WebUserControl" /> 
        
                <asp:Panel ID="Panel1" runat="server">  
        
                </asp:Panel> 
        
                    <Telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                        <AjaxSettings> 
        
                            <Telerik:AjaxSetting AjaxControlID="Button1">  
        
                                <UpdatedControls> 
        
                                    <Telerik:AjaxUpdatedControl ControlID="Label1" /> 
        
                                </UpdatedControls> 
        
                            </Telerik:AjaxSetting>

Filtering Issues (Several)

Hi,

I am having a few problems with Filters in the RadGrid.

My environment is Q3 2008, Dot Net 3.5 and I am mostly using FireFox as my Browser.

I think you need to put something into the FilterItem Text boxes when the filter function is something that does not take arguments (e.g. Is Null, Is Not Null and so on). When the grid is displayed it is not clear that filtering has been applied in these cases

In fact, it might also be nice if it was immediately clear to the user whether Contains, Startswith, EndsWith, Equals and son on are being used.

You have an example of some JavaScript to allow fairly sophisticated text entry into the filter boxes folllowed by pressing the Enter key - which I feel you could embed into the RadGrid functionality as a property (else we programemrs are continually pasting in chunks of code). You could extend the idea so that user gets more feedback about which filters are being applied
I have AutoPostBackOnFilter set to True (so i can use the javascript mentioned above). When I implement the GridDateTimeColumn I get a Date picker in my filter (which is absoultely great - and perhpas you ought to point this out in the documentation about column types - where you suggest that in non-edit mode there is no difference with a GridBoundColumn). My problem is that when I select a date from the picker, and before I get a chance to select the Filter Function, the postback occurs.

Yes, i can disable AutoPostBack for Date Columns, but it would be nice to get both features.

content div disappears with telerik grid

We have a asp.net with a content area that has abosolut position turned on. Inside this area we have a telerik grid using the outlook2007 skin. When the grid has data via the needsdatasource event the entire content div shrinks up to almost nothing. Strange thing is that when the we comment our the needdatasource event and the grid displays nothing but a shell the div does not shrink/disappear. In issue doesnt show itself in FireFox.

Thanks,
Kyle

RadWindow Display Issue - Doesn't Display Until Row Click

I have a call to display a radwindow alert after a record update in the rad grid 'UpdateCommand' like so:

    
            Protected Sub grid_dealerships_UpdateCommand(ByVal source As Object, ByVal e As Telerik.Web.UI.GridCommandEventArgs) Handles grid_dealerships.UpdateCommand 
        
                    Dim editedItem As GridEditableItem = TryCast(e.Item, GridEditableItem) 
        
                    Dim dealer_id As String = editedItem.OwnerTableView.DataKeyValues(editedItem.ItemIndex)("dealer_id") 
        
                    Try 
        
                        Dim dealer_name As String = (TryCast(editedItem.FindControl("txt_dealer_name"), TextBox)).Text 
        
                        Dim logged As Integer = Dealership_DataAccess.UpdateDealershipInformation(dealer_id, dealer_name) 
        
                        IF logged > 0 then     
        
                                DisplayMessage(String.Format("Dealership: <br/><br/><b>{0} - {1}</b><br/><br/> Was UPDATED SUCCESSFULLY!", dealer_id, dealer_name), "Dealership UPDATED") 
        
                        End If 
        
                    Catch ex As Exception 
        
                        DisplayMessage("Unable to update dealership record. Reason: " + ex.Message, "Update ERROR") 
        
                        e.Canceled = True 
        
                    End Try 
        
                End Sub 
        
                Private Sub DisplayMessage(ByVal text As String, ByVal title As String) 
        
                    RadAjaxManager1.ResponseScripts.Add("Sys.Application.add_load(function(){radalert('" & text & "', 330, 210, '" & title & "');})") 
        
                End Sub

Everything regarding the update works properly but the display alert does not show. If I select a different record on the grid to display or edit then all of a sudden the alert will show up correctly....

Here is my window manager from the aspx page which only displays a radWindow I use for a different purpose.

    
            <telerik:RadCodeBlock ID="RadCodeBlock1" runat="server"> 
        
                        <script type="text/javascript"> 
        
                            function ShowDealerIDs() { 
        
                                window.radopen("../shared/dealerID_list.aspx", "UserListDialog"); 
        
                                return false; 
        
                            } 
        
                        </script> 
        
                    </telerik:RadCodeBlock>  
        
                        <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> <AjaxSettings> 
        
                                <telerik:AjaxSetting AjaxControlID="RadAjaxManager1"> 
        
                                    <UpdatedControls> 
        
                                        <telerik:AjaxUpdatedControl ControlID="grid_dealerships" /> 
        
                                    </UpdatedControls> 
        
                                </telerik:AjaxSetting>       
        
                                <telerik:AjaxSetting AjaxControlID="grid_dealerships">

                                <telerik:RadWindow Skin="Default"  ID="UserListDialog" runat="server" Title="User List Dialog" Height="800px" 
        
                                    Width="550px" Left="100px" ReloadOnShow="true" Modal="true"  />

How Find RadWindow by Name in RadWindowManager

I am programmatically adding radwindows to my radwindowmanager. What's the best server-side code to use to search the radwindowmanager's windows and make sure the window does not exist already before adding it? I am assuming the windows might "exist" across postbacks and want to avoid dups.

Couldn't find good example of server-side usage of Find and related methods against radwindowmanager window collection.

Thx

[Solved] Refresh parent page after window selection

Here is my objective: I have a RadTextBox that opens a RadWindow when it receives focus. The RadWindow contains a RadGrid, which allows the user to select a row. Upon selection, the RadWindow closes and returns an a variable to the parent page. I then take the id that is returned, run a query to get a string value and place that string value in the RadTextBox. Everything is working fine until I try to put the string value in the RadTextBox. I can get the return value from the RadWindow and even place it in a label (see below).

    
            function refresh(id, name) {  
        
                            var lblEmployeeId = document.getElementById("<%= lblEmployeeId.ClientID %>");  
        
                            lblEmployeeId.innerHTML = id;  
        
                            var rtbFirstName = document.getElementById("<%= rtbFirstName.ClientID %>");  
        
                            rtbFirstName.value = name;  
        
                        }

The page will display the value for lblEmployeeId when the RadWindow closes, but not for rtbFirstName. However, if I click in rtbFirstName, the value will be displayed. I need it to display the same way as the lblEmployeeId. Please advise.
