What is the difference between the CheckState and Checked properties of a control in c?

checked is used to determine whether checkbox or checkboxlist is selected by true or false.

For example:1); The checked attribute of checkbox1 is assigned to the selected state.

2) if( The return value is bool type (true or false), and checkstate can also set whether a space is selected or not.

For example:"Please select",;

CheckedListBox1 is selected as a selection.

The name of the member of the checkstate.

checked The control is selected.

indeterminate The control is in an indeterminate state. An indeterminate control usually has a gray appearance.

unchecked The control is unchecked.

The easiest way:

It's that you click in the properties with one click"checkstate", see the comment on the property under the property box, the same goes for :"checked"And so it is!

Both checked and checkstate check the selected state of the control, and both can determine whether the control is selected.

Just checked by Boolean judgment (true & false).

checkstate is judged by enumeration.

The easiest way:

It's that you click in the properties with one click"checkstate", see the comment on the property under the property box, the same goes for :"checked"And so it is!

Double-clicking the button on the GUI will enter the following event method, and then add the ** in parentheses.

private void button1_click(object sender, eventargs e)

CheckState has three enumerated properties.

unchecked is not selected, the checked attribute is falsechecked is selected, the checked attribute is trueindeterminate If you are not sure whether it is checked, it can be modified, and the checked attribute is true

All you need to do in that box is set to indeterminate for checkbox.

If you want to return to the interminate state after the change, just continue to change the checkstate state.

In layman's terms"Not exactly".

Delegates are not selected"It's not".

Check (checkmark) to represent"Yes".

The box represents"Not exactly".

For example, the function of setting permissions for a certain system. There is a user group called"Press Commissioner".

There are a lot of users under this user group. Only a subset of these users have them"Delete the news"permissions. The other part does not have that permission.

At this time. "Press Commissioner"of this user group"Delete the news"Permissions should be"box"State. Because"Not exactly".

If the tick hits. All users in the group will have this permission. If unchecked.

All users in the group do not own"Delete the news"permissions.

You put"Press Commissioner"of this group"Delete the news"Permission to be revoked. Then go to a certain belonging"Press Commissioner"Users in user groups. Let him have that permission.

And the others remain the same. When you go back to the user group again. This"Delete the news"permission you have to make his status as"box".

Because"Not exactly".

The checkbox control in C, which sets its CheckState property to Indeterminate, is this state. A checkmark is displayed and grayed out, see msdn for details. v=

The popular meaning is uncertain, and it can be changed back after being changed.

His value is an enum type = ;
