How to customize a checkbox with Winform in C #
This article is to share with you about how to use Winform to customize a checkbox in C#. The editor thinks it is very practical, so I share it with you. I hope you can get something after reading this article.
Add a user control named: UCRadioButton
Take a look at the attributes.
[Description ("check change event"), Category ("Custom")]
Public event EventHandler CheckedChangeEvent
Private Font _ Font = new Font ("Microsoft Acer", 12)
[Description ("font"), Category ("custom")]
Public new Font Font
{
Get {return _ Font;}
Set
{
_ Font = value
Label1.Font = value
}
}
Private Color _ ForeColor = Color.FromArgb (62, 62, 62)
[Description ("font color"), Category ("custom")]
Public new Color ForeColor
{
Get {return _ ForeColor;}
Set
{
Label1.ForeColor = value
_ ForeColor = value
}
}
Private string _ Text = "radio button"
[Description ("text"), Category ("custom")]
Public string TextValue
{
Get {return _ Text;}
Set
{
Label1.Text = value
_ Text = value
}
}
Private bool _ checked = false
[Description ("selected"), Category ("Custom")]
Public bool Checked
{
Get
{
Return _ checked
}
Set
{
If (_ checked! = value)
{
_ checked = value
If (base.Enabled)
{
If (_ checked)
{
Panel1.BackgroundImage = Properties.Resources.radioButton1
}
Else
{
Panel1.BackgroundImage = Properties.Resources.radioButton0
}
}
Else
{
If (_ checked)
{
Panel1.BackgroundImage = Properties.Resources.radioButton10
}
Else
{
Panel1.BackgroundImage = Properties.Resources.radioButton00
}
}
SetCheck (value)
If (CheckedChangeEvent! = null)
{
CheckedChangeEvent (this, null)
}
}
}
}
Private string _ groupName
[Description ("Group name"), Category ("Custom")]
Public string GroupName
{
Get {return _ groupName;}
Set {_ groupName = value;}
}
Public new bool Enabled
{
Get
{
Return base.Enabled
}
Set
{
Base.Enabled = value
If (value)
{
If (_ checked)
{
Panel1.BackgroundImage = Properties.Resources.radioButton1
}
Else
{
Panel1.BackgroundImage = Properties.Resources.radioButton0
}
}
Else
{
If (_ checked)
{
Panel1.BackgroundImage = Properties.Resources.radioButton10
}
Else
{
Panel1.BackgroundImage = Properties.Resources.radioButton00
}
}
}
}
When the status change is selected, the corresponding processing needs to be done according to the group name.
Private void SetCheck (bool bln)
{
If (! bln)
Return
If (this.Parent! = null)
{
Foreach (Control c in this.Parent.Controls)
{
If (c is UCRadioButton & & c! = this)
{
UCRadioButton uc = (UCRadioButton) c
If (_ groupName = = uc.GroupName & & uc.Checked)
{
Uc.Checked = false
Return
}
}
}
}
}
Change the selected state when you click
Private void Radio_MouseDown (object sender, MouseEventArgs e)
{
This.Checked = true
}
Do some processing when loading to prevent multiple selections.
Private void UCRadioButton_Load (object sender, EventArgs e)
{
If (this.Parent! = null & & this._checked)
{
Foreach (Control c in this.Parent.Controls)
{
If (c is UCRadioButton & & c! = this)
{
UCRadioButton uc = (UCRadioButton) c
If (_ groupName = = uc.GroupName & & uc.Checked)
{
Checked = false
Return
}
}
}
}
}
Let's take a look at the complete code
