output grid data for consumption by iphone

Hi

Can you suggest what is the simplest way to output grid data to a web service for consumption
by an iphone app?

I am not familiar with iphone programming but I believe the preferred interface is json, although I
think XML is feasible.

Perhaps Telerik might consider specific support for such an interface in the future?

Thanks

Clive

[Solved] RadGrid and DynamicData Entity Web Site

Hello,

I'm trying to integrate your RadGrid control in a DynamicData Entity WebSite using the code I have downloaded from this Blog. In my Entity Model I have basically two Entity Sets: Orders and Customers from the Northwind database. Orders has a foreignkey on the parent table Customers.

The Orders scaffold table should contain a navigation link to Customers Table. As a matter of fact the databind process fails returning the following exception:

exception

DataBinding: 'NorthwindModel.Orders' does not contain a property with the name 'Customers.CustomerID'.

stacktrace:
   at System.Web.UI.DataBinder.GetPropertyValue(Object container, String propName)
   at System.Web.DynamicData.ModelProviders.TableProvider.EvaluateForeignKey(Object row, String foreignKeyName)
   at System.Web.DynamicData.MetaForeignKeyColumn.GetForeignKeyValues(Object row)
   at System.Web.DynamicData.MetaForeignKeyColumn.GetForeignKeyPath(String action, Object row, String path)

   at ForeignKeyField.GetNavigateUrl() in c:\Documents and Settings\Daniele\My Documents\Visual Studio 2008\Projects\DynamicDataRadGridTest\WebSite\DynamicData\FieldTemplates\ForeignKey.ascx.cs:line 59

   at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding)
   at System.Web.UI.Control.DataBind()
   at System.Web.UI.Control.DataBindChildren()

I have noticed two things:
1) the ForeignKeyField.FieldValue is null
2) the ForeignKeyField.Row is the Entity itself instead of an EntityDataSourceWrapper object

I could correct the first issue adding just a line of code in the Page_Load event handler of the ListDetails.aspx page

    
            protected void Page_Load(object sender, EventArgs e)  
        
            {  
        
                MetaTable table = GridDataSource.GetTable();  
        
                Title = table.DisplayName;  
        
                // Includes foreignKey Entities in the EntityDataSource  
        
                GridDataSource.Include = table.ForeignKeyColumnsNames;  
        
                //...  
        
            }

but I didn't figure out how to solve the databind issue

Any help is appreciated :)

Kind regards,
Simone

EDIT: I have uploaded my test project here. I hope this will help you to reproduce my problem

Hide Context Menu Server-side Code

Hi:

I'm wondering if there is a way to hide the context menu using server-side code. Specifically, If a user is logged in, then when the page loads, they can right-click and see the context menu. If the user is not logged in, then right-clicking on a node won't do anything.

The context menu is already built at design time. I don't want to re-build the menu at runtime.

Any help on how to ahcieve this is appreciated!

Thanks!

[Solved] Removing a Dock programmatically

Hello,

I've built a "portal" interface, combining dynamic TabStrip and RadDockLayout/Zone/Dock controls, fed from a database.

When the user clicks on a different tab, I want to show a different set of docks. On the postback, though, the docks from the soon-to-be-previous tab are still in viewstate and get reattached to their Zones. I added a method to clear them:

    
                ''' <summary> 
        
                ''' Clear all docks from a given raddocklayout 
        
                ''' </summary> 
        
                ''' <param name="rdLayout">given raddocklayout</param> 
        
                ''' <remarks></remarks> 
        
                Public Sub ClearAllDocks(ByVal rdLayout As RadDockLayout) 
        
                    Dim rdZones As ReadOnlyCollection(Of RadDockZone) = rdLayout.RegisteredZones() 
        
                    For Each rdZone As RadDockZone In rdZones 
        
                        rdZone.Docks.Clear() 
        
                        'For Each rdDock As RadDock In rdZone.Docks() 
        
                        '    rdDock.Closed = True 
        
                        'Next 
        
                    Next 
        
                End Sub

The .Clear() method isn't working. It just plain doesn't clear the Zone. The Docks are still there, before and after the .Clear() call.

I changed to the (commented out) .Closed = True option, but that seems slow and klunky to me.

a) is there a reason that .Clear() wouldn't work? I do realize I'm using a readonly collection to access them, but RegisteredZones only returns readonly.

b) is there a better way of clearing all the Docks in a Layout?

Thanks!

[Solved] GridEditCommandColumn and EditText

Hi All. Is it possible to change the EditText on a GridEditCommandColumn to a different value for each row? For example, I'd like to enter edit mode by click on a persons name. I'm doing all this in the code behind (C#). I can set the 'text' property but then I loose the link button. Thanks.

How can I can disable the zebra effect of a grid by setting the ClientSettings -> EnableAlternatingItems property of the grid to false

Hi,

I am using Telerik RadControls for ASPNET AJAX Q3 2008 on my current project.

I would like to disable the zebra effect on the grid on one of the web forms.

According to http://www.telerik.com/help/aspnet-ajax/grdcreatingnewskins.html I can do so by setting the ClientSettings -> EnableAlternatingItems property of the grid to false.

However the property does not seem to exist, and it is not possible to do this

1. At design-time as follows:

<telerik:RadGrid ID="radGrid" runat="server">

<ClientSettings EnableAlternatingItems="false">

<Scrolling UseStaticHeaders="true" />

</ClientSettings>

</telerik:RadGrid>

2. Programmatically as follows:

this.radGrid.ClientSettings. EnableAlternatingItems = false;

Can you please tell me how to do this?

Thanks & regards,

Herman Gouw
