Custom Control Design-Time SiteMap Provider Error

Posted By:      Posted Date: August 21, 2010    Points: 0   Category :ASP.Net

Greetings - I was referred here by MSDN forums hope this is the right place -  

I have a custom control (:WebControl) that renders web.sitemap in a specific way. While it runs error free and produces the expected result, at Design-Time it complains

Error Creating Control - MyControl  The provider 'AspNetXmlSiteMapProvider' specified for the defaultProvider does not exist in the providers collection.

I have discovered that the error is cause by this line of code:

string div = string.Format("<div class='{0}' id='{1}'>{2}</div>", this.CssClass, this.ID.ToString(), EnumerateNodesRecursive(SiteMap.RootNode, level));

or more specifically, by the reference to SiteMap.RootNode - I am not clear what is missing thoough because I have configured the SiteMapProvider in web.config as this:

        <add name="AspNetXmlSiteMapProvider" 
             type="System.Web.XmlSiteMapProvider, System.Web, Version=2.0.3600.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

Custom Control Design view error



I have created a custom control from scratch and it works fine as in you can build the project that uses it and it works fine at runtime. Problem is when you go to design view the control shows an error in the place of where the control should be rendered.

Error: '<SomeValue>' Could not be set to '<SomeProperty>'

This shows up on all my custom set properties. These properties are created as basic as possible. I can give the properties values in Source view and run the app just fine. I can even add a Onclick event. If I don't set any custom properties the control will render fine in Design view. It's only when I set a value to a custom property.

Property Code Example:

public string Text
                string ret = "";
                object obj = ViewState["Text"];
                if (obj != null)
                    ret = obj.ToString();
                return ret;
                ViewState["Text"] = value;

I've even removed the Category and Description tags with no difference.

I don't know if what I said makes sens, but I hope it

Accessing Property Value of a Custom Control by another Custom Control in Design-time



I created an Extender which has a custom property that drills down a list XML elements from an xml file, where users can select xml elements during design-time. This works perfectly fine. However, my code only has a hardcoded xml filename (source of the xml elements list) and I need to change this by maxing the xml file user-specified.

What I did is that I created another control (panel) which has a custom property that when clicked (through the ellipsis), it will allow a developer to select the xml file which is supposed to be the source xml file that the Extenders shall use. The filedialog from custom panel's property works perfectly fine.

However, my problem now is that when I drag-drop my Extender, I cannot find a way to get the property value of the custom Panel Control which contains the xml filename. I tried creating a static variable which I thought the custom controls can share but VS2010 is breaking.

Please take note that my problem is on Design-time, asp.net.

Appreciate any help. Thanks a lot.

How do I persist custom complex types in design-time


Let's say that I've got one custom webcontrol called MyControl.

public partial class MyControl: WebControl {
public IComplex Complex { get; set; }

The control is a very simple control but it holds an instance of a complex type that is accessable through a property. The property has the propertytype IComplex

public interface IComplex {
string Name { get; set; }
List<IComplex> Children {get;}

Let's say that I am able to pick one of several different types of object that derives from IComplex in design-time and assign it to the controls property "Complex" property.

Naturally I would like to persist this information to the HTML-View in a user-friendly way.

Because we don't know what type the user has picked there is no way to instansiate the type if we don't persist the name of that type. The Type could also contain more properties than the Interface the controls property is refering.

<cc1:MyControl id="MyControl1" runat="server">
<Complex> <!-

Data Binding: Give Your Everyday Custom Collections a Design-Time Makeover


In this article, Paul Ballard shows how you can provide data binding support for your custom collections to enable sorting, searching, and editing in as simple a manner as possible. In addition, he shows how to make all of these features available in the Windows and Web Forms Designers, just like an ADO.NET DataSet.

For a control which events are raised at design-time, run-time or both?

Hi. I have been getting several different errors on the my windows forms designer. I'm trying to implement an application with some complexity on the screen navigating since it includes several main views as also sub-views in which the sub-views are represented by user controls. I believe that some of my errors are related to the fact that I miss important information related the events that are raised while working in the windows forms designer. Is there any link that includes information about the events of a control that are raised at design-time, run-time or both? For example, if I override the OnLoad() method of a User Control, that method will be executed both at design-time and run-time. Knowing about this information has helped me resolving an issue related to duplication of columns on a customized DataGridView. Not 100% sure if it's possible to obtain what I'm asking for or if this information exists. If this information is not available what could I do in order to understand in more detail the kind of events that are raised in the design-time vs run-time? Can I debug an application in design-time using Visual C# 2008 Express Edition? I found this link that helps identifying the run-time and the design mode: http://dotnetfacts.blogspot.com/2009/01/identifying-run-time-and-design-mode.html This link has been helpful but I still feel that I need more information.

Cannot switch between tabs of a tab control at design time

Hi, I have the same problem as this fellows description below. Any suggestions? Cannot switch between tabs of a tab control at design time 06-11-2010 4:21 PM | Hi.

Custom panel - missing design time support for controls.

I’m trying to implement a custom panel, one that will behave kind of like the standard Canvas panel. The implementation is done and it is working when I add components in the xaml, but what is not working is move and resize of components in the designer. In the designer each component shows the ‘selected frame’ when selected, but it cannot be moved or resized. Can someone point me to what I’m missing, or an article that describes how do add this support?.   The reason I’m not deriving from the existing Canvas is mainly because I want to understand how it works and how to implement it manually.   Thanks

using Custom Formatter when format is unknown at design time

I have class "CF" that implements IFormattable interface. I can convert it to string var cf = new CF(); string str = cf.ToString("MYFORMAT", CultureInfo.InvariantCulture) or str = String.Format("{0:MYFORMAT}", cf);   the problem is that "MYFORMAT" is a parameter. so i can still use string fmt = "FORMAT"; string str = cf.ToString(fmt, CultureInfo.InvariantCulture) Is it possible still use String.Format for formatting? That doesnt work str = String.Format("{0:{1}}", cf, format)      

Controls Disappear in Custom Control Design View

I have a site using eight (so far) custom web user controls  and two of them have started misbehaving in design view.  When designing the control itself some (in one control) or all (in the other) regular controls (labels, text boxes, etc.) disappear from the design view surface.  They can still be seen in the source view and if the control is hosted on a regular .aspx page the control displays properly.  The code window recognizes all controls in the objects dropdown list and I can write appropriate code.  The controls run properly on their hosted pages.  If I switch to Split view and select controls in the source view panel a very small area od the design surface becomes selected (like one pixel for any of us who remember programming old DOS applications with 80-column screens) but no controls can be seen. In short, the controls work in every respect except that I cannot see all or part of the design surface in Design view when editing the controls directly.  I've double-tripple checked the source code for anything that may be causing this and just don't see anything.  (The controls aren't that complicated.)

How to implement Design-Time drag & drop from Custom Visual Studio Tool Window to WPF Designer

Hi, Could someone tell me if it is possible to intercept a design time drop event coming from a custom Visual Studio tool window onto the cider design surface? I am hoping to use the same API's as those used by the Visual Studio 2010 'Data Sources' tool window, which provides drag & drop data-binding between classes and WPF/Silverlight controls. My requirement is to pass a DataObject (used with the WPF DragDrop API) from my custom Visual Studio WPF tool window treeview to my custom WPF control at design time, read the data and do some binding/XAML manipulation of my own. The drag aspect is simple enough but I can't work out how to accept a drop event from anything other than the toolbox. At the moment, when I drag my treenode over the design surface it shows the 'cannot drop here' cursor. If someone could give me some insight into how the 'Data Sources' tool window allows dragging of treenodes to controls I would really appreciate it. It is obviously possible but which API's are used and are they public? Thanks in advance, Paul

Also I am unable to edit  the form or add anything from the toolbox.


Any help on this matter will be appreciated.
