How Do i Allow the user to select specific items by clicking on them while the control key is pressed

Question

I have a program that i need to be able to select multiple controls during runtime using the control key and a mouse click

How do i handle this event using keydown

it is a windows forms application containing 7 text boxes and a datagrid

i need the user to be able to use the control key as with many other applications to select individual controls at a time

Example: you have TextBox1 Textbox2 and so on

If the user only needs to copy individual contents to the clipboard they can hold down the control key on the keyboard and click the ones they need

I.E. If they need textbox1 and textbox4 only then they can hold the control key down and click on those two boxes or whatever boxes they need and copy the contents paste the contents cut the contents etc.

All i want to know is a simple and effective way to do this as it's used in most windows applications if someone knows a way other than the keydown event tell me i'll gladly take all solutions thanks

Thanks

You still don't get it; those other applications don't have that. What you are doing is unusual.

Still how do i do this? The deal is it's a random number type program they are output to textboxes for a reason of course but in the event the user wishes to copy select ones of these from the program to a file or whatever most time an average user not a programmer knows to hold down control and click on whatever they wish to copy the right click and copy. This is what i'm trying to make possible. Word notepad excel access most of your common windows applications has this functionality now how do i replicate it for my software Thanks

As best as I understand your question it is very unusual for Windows applications to work like that. It is usual for multiple items within a control (such as a DataGridView ListView or ListBox) to be selected like that but not multiple controls.

Oops the question was not at all clear can you add more data what you are trying to do . Do you want to handle Key down event separately for each and every control or what?
