Syncfusion has a free community version available with over 650 controls. 

[Syncfusion][1]

You will find an FAQ there with any licensing questions you may have, it sound great to be honest. Have fun! 

Edit: The WPF controls themselves are 100+, the number of 650+ refers to all controls for all areas (WPF, Windows Forms etc).

I searched for some good themes across internet and found nothing. So I ported selected controls of GTK Hybrid theme. It&#39;s MIT licensed and you can find it here:

It&#39;s not enterprise grade style and probably has some flaws, but I use it in my personal projects.

I have a string that looks like this:

    &quot;Name1=Value1;Name2=Value2;Name3=Value3&quot;

Is there a built-in class/function in Python that will take that string and construct a dictionary, as though I had done this:

    dict = {
        &quot;Name1&quot;: &quot;Value1&quot;,
        &quot;Name2&quot;: &quot;Value2&quot;,
        &quot;Name3&quot;: &quot;Value3&quot;
    }

I have looked through the modules available but can&#39;t seem to find anything that matches.

---
Thanks, I do know how to make the relevant code myself, but since such smallish solutions are usually mine-fields waiting to happen (ie. someone writes: Name1=&#39;Value1=2&#39;;) etc. then I usually prefer some pre-tested function.

I&#39;ll do it myself then.

Splitting a semicolon-separated string to a dictionary, in Python

I have a ArrayList&lt;Object&gt; made up of different elements imported from a db, made up of strings, numbers, doubles and ints. Is there a way to use a reflection type technique to find out what each type of data each element holds?  

FYI: The reason that there is so many types of data is that this is a piece of java code being written to be implemented with different DB&#39;s.

How do I find out what type each object is in a ArrayList&lt;Object&gt;?

I am looking for some recommendations on good places to find libraries of controls/templates/styles for WPF. I know about the usual places like Infragistics, but it seems to me that there should be some kind of community effort by now to share nice, clean, well written controls for WPF controls.

I am not big on the design side, and it would be nice to fill out my personal libraries with some nice examples from people who are better at design.

Any ideas or recommendations?

In WPF you can setup validation based on errors thrown in your Data Layer during Data Binding using the `ExceptionValidationRule` or `DataErrorValidationRule`.

Suppose you had a bunch of controls set up this way and you had a Save button.  When the user clicks the Save button, you need to make sure there are no validation errors before proceeding with the save.  If there are validation errors, you want to holler at them.

In WPF, how do you find out if any of your Data Bound controls have validation errors set?

Detecting WPF Validation Errors

I have a `ListBox` `DataTemplate` in WPF. I want one item to be tight against the left side of the `ListBox` and another item to be tight against the right side, but I can&#39;t figure out how to do this.

So far I have a `Grid` with three columns, the left and right ones have content and the center is a placeholder with it&#39;s width set to &quot;*&quot;. Where am I going wrong?

Here is the code:

    &lt;DataTemplate x:Key=&quot;SmallCustomerListItem&quot;&gt;
        &lt;Grid HorizontalAlignment=&quot;Stretch&quot;&gt;
            &lt;Grid.RowDefinitions&gt;
                &lt;RowDefinition/&gt;
            &lt;/Grid.RowDefinitions&gt;
            &lt;Grid.ColumnDefinitions&gt;
                &lt;ColumnDefinition/&gt;
                &lt;ColumnDefinition Width=&quot;*&quot;/&gt;
                &lt;ColumnDefinition/&gt;
            &lt;/Grid.ColumnDefinitions&gt;
            &lt;WrapPanel HorizontalAlignment=&quot;Stretch&quot; Margin=&quot;0&quot;&gt;
                &lt;!--Some content here--&gt;
                &lt;TextBlock Text=&quot;{Binding Path=LastName}&quot; TextWrapping=&quot;Wrap&quot; FontSize=&quot;24&quot;/&gt;
                &lt;TextBlock Text=&quot;, &quot; TextWrapping=&quot;Wrap&quot; FontSize=&quot;24&quot;/&gt;
                &lt;TextBlock Text=&quot;{Binding Path=FirstName}&quot; TextWrapping=&quot;Wrap&quot; FontSize=&quot;24&quot;/&gt;
    
            &lt;/WrapPanel&gt;
            &lt;ListBox ItemsSource=&quot;{Binding Path=PhoneNumbers}&quot; Grid.Column=&quot;2&quot; d:DesignWidth=&quot;100&quot; d:DesignHeight=&quot;50&quot;
         Margin=&quot;8,0&quot; Background=&quot;Transparent&quot; BorderBrush=&quot;Transparent&quot; IsHitTestVisible=&quot;False&quot; HorizontalAlignment=&quot;Stretch&quot;/&gt;
        &lt;/Grid&gt;

How to allow `TextBlock`&#39;s text to be selectable?

I tried to get it to work by displaying the text using a read-only TextBox styled to look like a textblock but this will not work in my case because a TextBox does not have inlines. In other words, how to make it selectable?

Any way to make a WPF textblock selectable?

In WPF, I want to create a hyperlink that navigates to the details of an object, and I want the text of the hyperlink to be the name of the object. Right now, I have this:

    &lt;TextBlock&gt;&lt;Hyperlink Command=&quot;local:MyCommands.ViewDetails&quot; CommandParameter=&quot;{Binding}&quot;&gt;Object Name&lt;/Hyperlink&gt;&lt;/TextBlock&gt;

But I want &quot;Object Name&quot; to be bound to the actual name of the object. I would like to do something like this:

    &lt;TextBlock&gt;&lt;Hyperlink Command=&quot;local:MyCommands.ViewDetails&quot; CommandParameter=&quot;{Binding}&quot; Text=&quot;{Binding Path=Name}&quot;/&gt;&lt;/TextBlock&gt;

However, the Hyperlink class does not have a text or content property that is suitable for data binding (that is, a dependency property).

Any ideas?

How can I set the text of a WPF Hyperlink via data binding?

I need to change the DataTemplate for items in a ListBox depending on whether the item is selected or not (displaying different/more information when selected).

I don&#39;t get a GotFocus/LostFocus event on the top-most element in the DataTemplate (a StackPanel) when clicking the ListBox item in question (only through tabbing), and I&#39;m out of ideas.

I want to build a site where the user can enter text and format it in Markdown. The reason I&#39;d like a Javascript solution is because I want to display a live preview, just like on StackOverflow.

My site is not targeted at developers, however, so an editor control would be ideal.

I gather that on StackOverflow, the WMD editor is being used.

A quick search on Google also turns up Showdown library, which I think is actually being used by WMD.

Are there any other options? Are WMD/Showdown great tools already? What have been your experiences with the different options?

All too often I want a WPF slider that behaves like the System.Windows.Forms.TrackBar of old. That is, I want a slider that goes from X to Y but only allows the user to move it in discrete integer positions.

How does one do this in WPF since the Value property on the Slider is double?

Are there any **professional** Combobox controls (dropdown list with autosuggestion) based on the jQuery library?

It should be able to handle **large datasets** and have some **skinning** options. A **multi-column result list** would be great too. I&#39;m working with ASP.NET, but it&#39;s a not a problem if I had to write a wrapper for it.

Professional jQuery based Combobox control?

This question is a result of what i noticed while trying to answer [another question][1]. And now im curious to know why `&lt;asp:TextBox runat=&quot;server&quot; Visible=&quot;&lt;%= true %&gt;&quot; /&gt;` leads to a compile error, and not to a visible TextBox as i would have expected.

From what i have discovered so far, the `&lt;%= %&gt;` expressions are not translated to literal controls as i have always thought. But instead it is evaluated and written directly to the HtmlTextWriter when the page is rendered. But apparently the parser (I&#39;m unsure that is the correct term for the part that is translating ASP.NET markup to .NET code) doesn&#39;t even attempt to evaluate `&lt;%= %&gt;` expressions, when they are used as property values for server controls. It just uses it as a string. Which i guess is why I get the error message: *Cannot create an object of type &#39;System.Boolean&#39; from its string representation &#39;&lt;%= true %&gt;&#39; for the &#39;Visible&#39; property*. 

If i instead ditch the runat=&quot;server&quot; and combines the `&lt;%= %&gt;` with regular html-markup, like this:

	&lt;input type=&quot;button&quot; id=&quot;Button1&quot; visible=&#39;&lt;%= true %&gt;&#39; /&gt;

Then the parser just splits the chunk in parts before and after the expression and then writes it to the HtmlTextWriter in the render method. Something like this:

        __w.Write(&quot;&lt;input type=\&quot;button\&quot; id=\&quot;Button1\&quot; visible=&#39;&quot;);
        __w.Write(true);
        __w.Write(&quot;&#39; /&gt;&quot;);


As the last thing i noticed... When i try with `&lt;%# %&gt;` + Control.DataBind(), then i get what i would expect. It hooks up the expression to be used when the control is databound, but unlike the &lt;%= %&gt; expression, the generated code actually evaluates the content of the `&lt;%# %&gt;` expression. The parser ends up generating the following:

	[DebuggerNonUserCode]
	private Button __BuildControldataboundButton()
	{
		Button button = new Button();
		base.databoundButton = button;
		button.ApplyStyleSheetSkin(this);
        button.ID = &quot;databoundButton&quot;;
		button.DataBinding += new EventHandler(this.__DataBindingdataboundButton);
		return button;
	}

	public void __DataBindingdataboundButton(object sender, EventArgs e)
	{
		Button button = (Button) sender;
		Page bindingContainer = (Page) button.BindingContainer;
		button.Visible = true;
	}

From:
	

    &lt;asp:Button ID=&quot;databoundButton&quot; Visible=&#39;&lt;%# true %&gt;&#39; runat=&quot;server&quot; /&gt;

Notice the `button.Visible = true;` that is the result of the `&lt;%# %&gt;` expression.

So my question is.. Why is the expression in the first example just treated as a string, instead of being evaluated to &quot;true&quot;. The expressions is somewhat similar for the two other examples, and they yield the code i would have expected.

Is it just a mistake (which i doubt since it isn&#39;t a new issue with the current version of ASP.NET), or is there a good reason why we are not allowed to use `&lt;%= %&gt;` like that?

I need to search a WPF control hierarchy for controls that match a given name or type. How can I do this?

How can I find WPF controls by name or type?

In C# we can define a generic type that imposes constraints on the types that can be used as the generic parameter. The following example illustrates the usage of generic constraints:

    interface IFoo
    {
    }


    class Foo&lt;T&gt; where T : IFoo
    {
    }

    class Bar : IFoo
    {
    }

    class Simpson
    {
    }

    class Program
    {
        static void Main(string[] args)
        {
            Foo&lt;Bar&gt; a = new Foo&lt;Bar&gt;();
            Foo&lt;Simpson&gt; b = new Foo&lt;Simpson&gt;(); // error CS0309
        }
    }

Is there a way we can impose constraints for template parameters in C++.


----------

C++0x has native support for this but I am talking about current standard C++.

Template Constraints C++

I am looking for a template engine to use client side. I have been trying a few like jsRepeater and jQuery Templates. While they seem to work OK in FireFox they all seem to break down in IE7 when it comes down to rendering HTML tables.

I also took a look at MicrosoftAjaxTemplates.js (from http://www.codeplex.com/aspnet/Release/ProjectReleases.aspx?ReleaseId=16766) but turns out that has the same problem.

Any advice on other templating engines to use?

jQuery templating engines

I&#39;ve been programming in C++ for a few years, and I&#39;ve used STL quite a bit and have created my own template classes a few times to see how it&#39;s done.

Now I&#39;m trying to integrate templates deeper into my OO design, and a nagging thought keeps coming back to me: They&#39;re just a macros, really... You could implement (rather UGLY) auto_ptrs using #defines, if you really wanted to.

This way of thinking about templates helps me understand how my code will actually work, but I feel that I must be missing the point somehow. Macros are meant evil incarnate, yet &quot;template metaprogramming&quot; is all the rage.

So, what ARE the real distinctions? and how can templates avoid the dangers that #define leads you into, like

  - Inscrutable compiler errors in
    places where you don&#39;t expect them?
  - Code bloat? 
  - Difficulty in tracing code?
  - Setting Debugger Breakpoints?
