When you add a TabControl in the VS 2010 designer, you get a TabItem added by default. (And a grid in the TabItem.) How can I duplicate this same type of effect in a custom control?
Interestingly, Expression Blend 4 will add two tabs to the TabControl by default.
Thank you for your answer.

All you have to do is add a UserControl to your project, add whatever controls you need, and then after you build your project, it will be available in the Toolbox, at the top under "yourProjectName" Controls. Then you can add this to any form, and it will automatically add all the other controls you added.

Perhaps I wasn't clear on my request. I have already made a custom control & can add it via the toolbox. This control has content that can be added by the developer. This is like the TabControl - you can add TabItems and add your own controls in the TabItem.
The problem is that there is no initial clue for what/where to add your controls. The TabControl is nice because the designer pre-populates a TabItem for you.
How do you get the designer to pre-populate a non-default value for you? (By default, the TabControl has no items. But the designer adds one for you when you add it via the toolbox.)
Thank you for your response.

OK, I get it now. Unfortunately, I can't help you with that, sorry!

I want to communicate with serial port on client side system via asp pages.I think silverlight is the best solution,but there is no asp.net sample about this topic.
would you please tell me if there is a sample in this site or other web pages?
thanks

Silverlight is not the best option for what you are trying to do.
Silverlight runs in a sandboxed environment where accessing serial ports is not possible.

This site needs to sign in but I don’t know why I can’t sigup

Create a webservice on the server side that accepts the port data and a desktop app on the client side that reads the serial port and sends the data to the webservice.
Or; use automation (via MSHTML or a webbrowser control) to update the ASP page from a desktop app that reads the serial port.
Or; create a webservice on the client side that reads the serial port; a Siverlight app on the client side can then access the webservice to get port data.

Thanks for your answer.
Is there any sample about these ideas?
|
|
|
|

I gave you 3 options; you first need to decide which option you are going to use, and then break out it's components.
After that, there are plenty of examples out there (including on this site) to:
1) create a web service (server and/or client side)
2) read a serial port
3) browser automation using MSHTML
4) browser automation using the web browser component
5) calling javascript on a page and passing parameters

What hapened if there was a sample including this five issues together?
I'll try again to achieve my purpose.
But I hope I would make a component,when user connects to my website an activex download pops up and he accept it then every thing will be solved through internet borrowser.
Is that possible?i'm sure but it's too difficult for me.

|
|
|
|
First off, I wouldn't use an ActiveX control - that will limit you to PCs. Secondly, what exactly are you expecting from us?
|
|
|
|

Everything is possible (if you want it bad enough).

Hello everyone
I have two images, image1 represent lunch and image2 represents dinner. When I run my application the image1 is displayed on main window.
How can I change image1 to image2 corresponding time of day (at run-time)?
For instance: lets say
from 12:00 to 17:00 I want my image1 to be displayed at main window, and
from 17:00 to 23:00 I want to display image2 at main window.
could someone please help me solve this problem, Hence: I'm new to WPF...
thanks in advance
kind regards

Presumably you have a property representing the image to be displayed and bind your xaml to the property.
You then need a timer in your code (code behind or ViewModel). In the timers tick event you check the datetime.now and change the image property to the image you want to display.
