I have created a user control with a TextBox and two Buttons, but I haven't created events, just I place them to user control. When I want to add the user control to my form it says:
Cannot move Task_control.cs. The destination folder is the same as the source folder.
I can't understand why.

Add the control by drawing Select the control by clicking on it. In your form, drag-select a region. The control will be placed to fit the size of the region you selected.
After adding control in tool box you can drag and drop control in your form where you want to use this control. Its my user control you can make own user control according to own requirement. If you want to get the custom control selected value and selected text write this code.
A UserControl is a collection of controls placed together to be used in a certain way. For example you can place a GroupBox that contains Textbox's, Checkboxes, etc. This is useful when you have to place the same group of controls on/in multiple forms or tabs.
User controls are a way of making a custom, reusable component. A user control can contain other controls but must be hosted by a form. Windows forms are the container for controls, including user controls. While it contains many similar attributes as a user control, it's primary purpose is to host controls.
After creating your user control, you should build the project (F6 or Ctrl+Shift+B).
Then Visual Studio automatically adds the control to the Toolbox. You should drag the control from the Toolbox (Ctrl+Alt+X) to the form.
If after successfully building the project, the control is not on the Toolbox, make sure that you have Automatically Populate Toolbox set to true: Go to Tools->Options, select Windows Forms Designer node, and set Automatically Populate Toolbox to true.
You can also manually add your user control to the toolbox (if "Automatically Populate Toolbox" is not set, and you don't want to set it!). It is highly recommended that you create an additional Tab on the Toolbox for your specific user controls: Right click on an empty area of the Toolbox and click Add Tab, then give the new tab a name.
Now build the project, right click on an empty area on the toolbox (of course, in tab you already created, or in the "General" tab), and select Choose Items:
Wait a few seconds (or minutes) for the dialog to be ready, then click Browse and select your assembly. All of your user controls are now in the list. Select the ones you want to add to the Toolbox and click OK.
