The use of C# control CheckBox

Use the CheckBox control
Today, I used the CheckBox control, record it here.

Tools: Visual Studio 2017 (other versions also work)

Method/step:
1. Drag the CheckBox control to the window, as shown in the following figure:

2. Change the name of the control to CBox

3. Common methods of this control:
this.CheckBox.Checked = true; //Set the control state to checked
this.CheckBox.Checked= false; //Set the control state to unchecked
//or
this.CheckBox.CheckState = CheckState.Checked; //Set the control state to checked
this.CheckBox.CheckState =CheckState.Unchecked; //Set the control state to unchecked
4. How to judge the current state of the control
this.CBox.Checked

if(this.CBox.Checked==ture)
{
MessageBox.Show("Choose");
}
else
{
MessageBox.Show(“No Choose”);
}
5. Double-click the control, an event will be added (when the state of the control changes)

At this time, a function related to the attribute will be generated, and the related function can be realized by editing the function, as shown below:

 private void CBox_CheckedChanged(object sender, EventArgs e){if (this.CBox.Checked == true){MessageBox.Show("Choose");}else{MessageBox.Show("No Choose");}}
