Long story short, I created a custom winform TabControl:
public sealed class MyTabControl : TabControl
And I can't find a way to add other controls to its TabPages. When I drag and drop any kind of Control (a Button, for example, or a Panel) on the top of a TabPage display area, it's added to the Form instead of being added to the page itself. Anyone can explain me why and how to implement Designer interaction to my custom Control?
First you have to add your "MyTabcontrol" to tool box.
How to do that:
On the Tools menu, click Choose Toolbox Items.
On the .NET Framework Components tab, click Browse.
In the Open File box, locate the DLL that was built when you created the UserControl control.
Then Drag UserControl from the toolbox to Form.
Then it works.

I am having trouble drag-dropping user controls into the design view on a winform. I am able to go through the toolbox, create a new tab, and choose items drag drop my control.
I am unable to go in through the design view and drag the control onto the design view. Is design view from solution explorer drag-drop supported? Going through the toolbox is a lot of steps which makes it hard to test. Is the toolbox the only option?
The ToolBox is the only option to drag-drop (custom) controls onto a winform. When you create a seperate assembly for custom controls and reference it in the project where you need the controls VS2010 should automatically add your custom controls (from the referenced project) to the ToolBox. Although the ToolBox behaves "weird" sometimes for unknown reasons.
I don't believe that it is supported.
The control needs to be compiled before it can be used in the form. So dragging from the solution explorer would not be possible.
In WinForms C# using .Net 2.0 I want to add a TabControl to a Form that has existing controls. Is there a way to move all the controls into a tab control without Visual Studio blowing away all my event handlers the like? Using Visual Studio 2005.
Yes, make the form as large as possible and draw a tab control on the right side of the form. Then select all the controls on the left side and drag them on the tab control. Now your event handlers will remain intact and controls will be placed on the tab control nicely.
I would select all of the controls on your form, hit Ctrl-X (cut them), put the TabControl on your form and make it as big as you need, then hit Ctrl-V to paste all of the controls into the TabControl. This will maintain the state of all of your controls..you won't lose event handlers or anything.
How can I add WPF form into tab item of tab control?
like I have make wpf form, I need to add in tab control collection just like when we open wpf form in VS 2010 and it is open in Tab MDI form and different forms are showing in different tab.
Thanks
Don't use Forms to put n Tabpages. Use UserControls instead. You can put them there with the designer.
I built a little console application in C# and need to add a windows form interface to it. I added a form item, and now have a blank form. I don't know how to go from here and start adding buttons and menus to the form.
Is there a form design toolbar or do I have to add buttons and menus using code?
Choose Toolbox from the View menu..
Click View>Other Toolbars>Toolbox to show the toolbox containing common controls for Windows forms.
I plan to add functionalities to TextBox with the following:
public class TextBoxExt : TextBox
{
protected override void OnKeyPress(KeyPressEventArgs e)
{
base.OnKeyPress(e);
}
}
The question is how can we use this TextBoxExt? Is there anyway to get this class onto the ToolBox so that we can just drag and drop it onto the form? If not, what is the best way to use the TextBoxExt?
I believe there are a couple of ways to get your control to appear in the toolbox:
The project it's in must be included in your open solution and the project must have been compiled/built into an assembly. This is the route to go if you're working on the control and a project that uses the control at the same time (e.g., building the solution will also re-build the control's project).
You can right-click the toolbox to add new items... in the resulting dialog, you can browse to the assembly containing the control and add it that way (or add it to the GAC, in which case you can pick it right from the list without browsing). This is the route to go if the project containing your control won't be a part of your solution and you're dealing only with the compiled DLL (e.g., building the solution doesn't re-build the control's project).
There is an another simple option to add a control into Toolbox is,
Create a new toolbox tab in the VS Toolbox. Say for e.g. "My Own Control".
Drag the assembly which has your control into the newly created tab and drop it.
You can see your control added in your Toolbox.
Main advantage of this method is, if you have more than a control in your single assembly, you do not need to search in the Add Components dialog and choose them. VS will do it for you and will add all those automatically in Toolbox.
Hope this helps.
Just compile your application - TextBoxExt should then show up in your Toolbox (you'll see it at the top, whenever you have a form designer open), and you can drag it onto your form.
The key here is probably to have a form designer open - otherwise, you won't see your custom user control in the toolbox.
