You meant that you need postback after checkbox is checked or you want to check some checkboxes and after that to post back the page by button?

If you want to go in session way, it's very simple. Store items collection in session object: Session["MyKey"] = MyList.Items; And on another page retrieve them from session: ListItemCollection items = Session["MyKey"]; After that you can go thought collection of the items again and retrieve values...

Sure you can print it! :) Attach to button this client script "window.print()" it's all you need to do. Also you can put two functions on your page function window.onbeforeprint() { //Make you changes before printing, like //hiding unnecessary while printing elements } and function window.onafterprint() { //Restore previous state after printing }

Make search on word "obfuscator"

And which kind of application is? windows form or web

You can start the process, but windows service can't have window. A solution can be window application (form) that appears invisible all the time.

I need to build TextBox control that will display baloon tooltip if entered value is invalid. The question is, how can I retrieve size of such tooltip to allocate it on right place? Thanks.

There is table with name TableName in first dataset Id Name Selected ---------------------- 1000 Name1 0 1001 Name2 0 1002 Name3 0 There is table with the same name in second dataset Id Name Selected ---------------------- 1000 Name1 1 How can I merge them to get this: Id Name Selected ---------------------- 1000 Name1 1 1001 Name2 0 1002 Name3 0 I prefer to do this by using Merge method, but not with foreach...

thanks :) that is exactly what I need

There is a lot of information there... unfortunately I have not found what I need, but thanks. Declare additional constructor with different from void parameters will be not so "right" way. It must be something that resolves this problem...

there is your code, I believe it works :) //load needed image from file Image src = Image.FromFile(/*your image file name*/); Graphics gr = Graphics.FromImage(src); Point point = new Point(1, 0); for (int i=0; i<3; i++) { //handles the pixels of separated image Bitmap bitmap = new Bitmap(300, /*your image height*/, gr); //draw the needed part of entire image gr.DrawImageUnscaled(src, point); //make offset to next part point.Offset(303, 0); //save the destination image bitmap.Save("filename.bmp", System.Drawing.Imaging.ImageFormat.Bmp); }

It's seems that your problem is to separate one peace of entire image from other. If there is width of each peace is constant it will be very easy, but if not, you need to "search for black line"... What exactly you want to know?

I have a control inherited from ComboBox. In constructor I add some items. Now, when my control is have been putted onto form designed calls to constructor and item collection is automatically updates. How can I prevent this action, some directive or attribute that tells to designer not to call to constructor during the design time?

first of all sorry about my english, but it's all what I have :) so, that's the question. In all controls in the form in properties window (in the bottom right) appears (DataBindings). What is this and how to use it? I heard that is helps to separate all stuff about how controls react for user's action. I mean, if user click checkbox some text field can be disabled.

May be somebody knows if such thing is exist. I mean, to compile project in c# into executable file like c++ does?
