1. Common attributes:

(1) Checked property: used to set or return whether the radio button is selected. The value is true when selected and false if it is not selected.

(2) AutoCheck property: if the AutoCheck property is set to true (the default), all other radio buttons in the group are automatically cleared when the radio button is selected. For the average user, there is no need to change this attribute, just use the default value (true).

(3) Appearance property: used to get or set the appearance of the radio button control. When it is Appearance.Button, it makes the radio button look like a command button: when it is selected, it appears to have been pressed. When the value is Appearance.Normal, the default radio button looks like.

(4) Text property: used to set or return the text displayed in the radio button control. This property can also contain access keys, that is, preceded by "&"

Symbol so that the user can select the control by pressing the Alt key and the access key at the same time.

2. Common events:

(1) Click event: when a radio button is clicked, the value of the Checked property of the radio button is set to true, and the Click event occurs.

(2) CheckedChanged event: the CheckedChanged event is triggered when the value of the Checked property is changed.

The radiobutton in WPF may be a little different from that in Web. There are no attributes such as group. When using, put the same group of radiobutton directly into a groupBox or panel, and they will automatically be a group. There are two ways to use it (to determine which one is selected):

The first method:

The copy code is as follows:

Foreach (Control ctrl in groupBox1.Controls)

{

If (ctrl is RadioButton)

{

If ((RadioButton) ctrl) .Checked)

{

/ / add the actions you need

}

}

}

The second way: add events to each radiobutton

The copy code is as follows:

Private void radioButton_CheckedChanged (object sender, EventArgs e)

{

RadioButton rb= (RadioButton) sender

If (rb.Checked)

{

/ / add the actions you need

}

}
