In WinForms
I am using a Label
to display different messages like success, failure, etc.
I'd like to center that label in the center form. I want a solution that will keep i开发者_Go百科t centered whether there's just one word or a whole sentence in the label.
Set Label
's AutoSize
property to False
, TextAlign
property to MiddleCenter
and Dock
property to Fill
.
You will achive it with setting property Anchor: None.
Some minor additional content for setting programmatically:
Label textLabel = new Label() {
AutoSize = false,
TextAlign = ContentAlignment.MiddleCenter,
Dock = DockStyle.None,
Left = 10,
Width = myDialog.Width - 10
};
Dockstyle and Content alignment may differ from your needs. For example, for a simple label on a wpf form I use DockStyle.None.
If you don't want to dock label in whole available area, just set SizeChanged event instead of TextChanged. Changing each letter will change the width property of label as well as its text when autosize property set to True. So, by the way you can use any formula to keep label centered in form.
private void lblReport_SizeChanged(object sender, EventArgs e)
{
lblReport.Left = (this.ClientSize.Width - lblReport.Size.Width) / 2;
}
The accepted answer didn't work for me for two reasons:
- I had
BackColor
set so settingAutoSize = false
andDock = Fill
causes the background color to fill the whole form - I couldn't have
AutoSize
set to false anyway because my label text was dynamic
Instead, I simply used the form's width and the width of the label to calculate the left offset:
MyLabel.Left = (this.Width - MyLabel.Width) / 2;
I wanted to do something similar, but on a form with a background image, I found that when the text in the label changed the repaints were obvious with this method, so I did the following: * Set the label AutoSize to true and TextAlign to MiddleCenter
Then, each time the text changed (mine was done using a timer) I called the following method:
private Point GetPosition()
{
int y = (this.Height / 2) - (label1.Height / 2);
int x = (this.Width / 2) - (label1.Width / 2);
return new Point(x, y);
}
And set the label's Location property to this return value. This ensured that the label was always in the center of the form when the text changed and the repaints for a full-screen form weren't obvious.
You could try out the following code snippet:
private Point CenterOfMenuPanel<T>(T control, int height=0) where T:Control {
Point center = new Point(
MenuPanel.Size.Width / 2 - control.Width * 2,
height != 0 ? height : MenuPanel.Size.Height / 2 - control.Height / 2);
return center;
}
It's Really Center
