Hi,
Could you please suggest how to reduce the speed of the Accordian item control. By default it is moving fast. Need to reduce the speed on click of accordian item.

Thanks in advance!

I don't see any property or method exposed to control the speed.

I imagine you'll need to provide a custom template for AccordionItem.

The default template is in the toolkit source code (AccordionItem.xaml).

DataGrid AutoGeneratingColumn event+Command?

I need to perform some action on AutoGeneratingColumn event of wpf DataGrid.
But i can`t use generated event handlers.So i wonder can i specify somehow(by "gesture")that once AutoGeneratingEvent occurs SomeCommand should be executed.
Smth like:

<toolkit:DataGrid.InputBindings>
     <MouseBinding Gesture="LeftDoubleClick" Command="local:RegistryTab.ShowServiceDescriptorDialogCommand"/>
     <UnknownBinding Gesture="AutoGeneratingColumn" Command="local:RegistryTab.AutoGeneratingColumnCommand"/>
</toolkit:DataGrid.InputBindings>

I have a button, and its background image is a bmp file. Background of image is black. How to make this black color transparent

I hope in WPF you can only have Transparent PNGs and not BMP files. Visit the link. http://social.msdn.microsoft.com/Forums/en-US/wpf/thread/af19bb61-3558-4b19-9f4d-abdc5816f073[^].

So try to convert the bitmap image into PNG by setting transparent backround in the image itself.

If you found a solution let me know, so that I can also follow that in my future projects.

You just could set the transparency mask of the image control that is hosted inside your button ...
The fileformat of the picture hosted inside the imagecontrol is not important at all.

Sorry, is this a Windows.Forms Button ? If so, my answer is only for WPF ... This comes from quick and dirty reading ...

Thanks for your reply. I fixed my problem by using icom image instead of bitmap as background of button. It is also possible to create transparent image using photoshop.Go through the link

Did you leave a localhost URL somewhere, perhaps in your HTML or web.config?

Is it possible to dynamically load a usercontrol from a (.net) library?

Re: WPF dynamic load of UserControl

Mark Salsbery28-Sep-09 7:16

Re: WPF dynamic load of UserControl

28-Sep-09 7:16

All the "built-in" controls you use are dynamically loaded from libraries
so I'd say yes, it is possible.

Add a reference to the library, create an object of a public class that's
in the library, and go...

Or did you mean to ask something more specific?

Hello Mark!

Thanks for the prompt answer!
I need to be more specific ...

When the (WPF) windows loads I want to load a UserControl from pos.dll for example.
How do you add dynamically controls in a WPF window ?

I want to use Conditional Compilation Directives (#if, #endif) in my XAML file as well as in the codebehind file. Can anybody provide me links or sample code?

Is there any other technique to do the same? Please guide me.

ex.

#if TASK
  <Button Click="AddTask">Add Task</Button>
#else
  <Button Click="AddContact">Add Contact</Button>
#endif

You can only use the Conditional Compilation Directives in code behind. As you can see, they are not valid XML, so they are not suitable for use in XAML. From the look of the quick sample you've posted, you might want to use DataTemplates, Template Selectors and the MVVM pattern. Have a look at Josh Smith's article on MSDN to get a better understanding of this.

I can do better than that - I can give you an idea of how I think, which hopefully means you can perform the same actions as me in future. This should mean that you don't have to wait for others to give you answers, instead you will be able to do your own research, saving you time, and increasing your effectiveness as a developer.

First of all, I thought to myself - how can I find the link to this article? I can't remember the URL of this article, but I can think of some mechanism which will allow me to look something up off the internet. So, once I've ascertained that I can't remember the URL directly, I know that I need to look it up from a search engine. At this point, I need to think of the keywords that will help me perform an effective search. Well, we know that the article was written by Josh Smith, we also know it was written for the MSDN magazine and it was about MVVM, so I can make an educated guess at the keywords; namely Josh Smith MVVM MSDN magazine. A quick hop on over to Google and I enter these keywords, hit search and what do you know, the first result is the one I want[^].

When you can think how to search for answers yourself, and not rely on others to do the searching for you, you will be able to make drastic leaps forward in your effectiveness and ability as a developer.
