How to Add Tasks to UserControls?

Same appearance needs same framework.

If your group want to have a solid architecture your group must have (or make) your own framework.

Then your user controls will be as you want.

The question contains one of the possible answers — UserControl:

Create a UserControl, put a text box and a small button with a small black arrow on right side, the button click will shows a small panel with its child controls. To mimic a list part of the combo box, this small panel should be shown on a separate window created immediately on top of the desktop -- this is how native combo box shows drop-down list. You will need to have separate window because the height of the combo box is equal to the height of its text box part, so the list box part (or your small panel) will not fit in the user control; dynamic increase of the user control size also will not work, because it would mess up the parent's layout.

This is not easy at all, by the way. It will require handling good number of events, taking care of tricky layout, expose sophisticated interface to allow the user of your control populating and accessing polymorphous list of the panel's child controls.

One example of a very characteristic problem: when a native combo box is shown in a form, and when it's drop-down list is shown, the user can deactivate the active form. You could have noticed: this hides the combo box's drop-down list; this is done this way to prevent this list box (at the level of desktop children) messing up with other top-level windows. But this activation events belong to the form, not to the control, so the appropriate action should be delegated to the form during run time...

Still interested to try?

Hi,Thank you for the answer.
But how its Possible that all the components that we have from diffent companys(Microsf,Dev,and...)Have the Same Take panel in their Components???
And also i have seen some of my friend created this Taks panel exacly like the thing we have in C# Controls!!!
It seems there must be a Standard.
And the way you said is UnPro.
I wait to get a better way...
Again Thank you for giving me your time.
