[Custom control] Dynamically evaluated properties?

Posted By:      Posted Date: October 04, 2010    Points: 0   Category :WPF

There's a control with propertygrid-alike UI, accepting IDictionary with a known keys set (let it be the SqlConnectionStringBuilder for example. Actually, it is a custom class).

I do not wish to specify key values in template bindings (e.g. Text = "{Binding SourceProp[keyName], RelativeSource={RelativeSource TemplatedParent}}"), so I've added set of protected properties and bind them to the SourceProp property

    public CustomControl()
        new Binding("SourceProp[keyName]")
          Mode = BindingMode.TwoWay,
          Source = this

Problem binding business objects to custom user control properties

I have created a user control (supplierPicker) intended to allows a supplier database to be searched and a supplier selected. I want to be able to use this control in a number of other user controls, by binding the suppplierID property of the supplierPicker to a supplierID property in a business object, which is set as the datacontext of the parent user control. When I do this, and there is a supplierID specified in the business ofbject, the binding sets the supplierID in the supplierPicker control and it shows the correct supplier name in the textbox. However when the supplierID DependencyProperty is changed from within the supplierPicker the newly selected supplier name is shown in the TextBox, but the SupplierID does not propogate back to the business object. Other controls on the parent form work fine, so the binding to the business object seems to be ok. Any pointers as to what I'm doing wrong here would be grately appreciated.  This one has been driving me nuts for days! Snipped code for the supplier picker:         public partial class SupplierPicker : UserControl, INotifyPropertyChanged     {         public static DependencyProperty SupplierIDProperty;         public event PropertyChangedEventHandler PropertyChan

Sharepoint 2010 Custom Field Types & Field Properties ( Editor Control )



I've been searching this forum and all over the web for a working example of how to implement a Editor Control with a Sharepoint 2010 custom field type.

The only documentation on MSDN mentions the implementation of IFieldEditor. There are no propper examples of how to implement properties on custom field types.

All I could find on MSDN regarding this issue was :



Has anyone done anything simmilar and know of a propper example of how to implement it?

using the linqDataSource control programmatically (dynamically)



my scenario is this: I want to use the linqDataSource control to bind data to a gridview for it's efficient built-in paging and sorting features *but* I don't want the data to be bound until the user has input various search parameters, so I need to bind the data from a button click event. Also, the search options will be somewhat complex in that there will be several optional search parameters, via various dropdowns and textboxes, so I can't just declaratively/statically setup all the WHERE parameters on the linqDataSource (at least I'm assuming I can't, or that it may result in poor performance if I do and just assign default values like the everything wildcard '%' for the cases the user doesn't use a particular search parameter). Given that brief description, here is an example of what I'm doing, but with only one WHERE parameter for simplicity, the real code will be adding anywhere from 1 to about 12 WHERE parameters depending on how the user sets the search options in the GUI.

the linqDataSource on the aspx page:

<asp:LinqDataSource ID="ldsMain" runat="server" 
        Select="new (field1, field2, field3, etc..)" 

Custom Control Design-Time SiteMap Provider Error


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 Server Control Property not maintaining state


I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below


<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.


What am i missing





Persist data in a dynamically populated ListBox in a user control


Hi All,

I am trying to persist data in a dynamically populated ListBox in a user control. Here are the details

I have a user control which contains a a listBox and button. On Page_Load of user control I am populating the ListBox control with some values. On Click of button, I am trying to fetch the values which I have selected in ListBox. Though this seems very simple and straight forward I am unable to fetch values.

My Click Function

Protected Void Button1_Click(object sender, EventArgs e)

I have placed brake point at Page_Load and on click function, I am seeing that the moment the breakpoin

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

Cutting Edge: Custom Data Control Fields


In ASP. NET 2. 0, the GridView and DetailsView controls are designed to work together. They don't merely provide complementary services, they also share a number of helper classes and components. The output of the GridView control consists of a sequence of rows, each with a fixed number of columns.
