I have a Windows Forms Application where I display some client data in a Label.
I have set label.AutoEllipsis = true.
If the text is longer than the label, it looks like this:
Some Text
Some longe... // label.Text is actually "Some longer Text"
// Full text is displayed in a tooltip
which is what I want.
But now I want to know if the label makes use of the AutoEllipsis feature at runtime. How do I achive that?
Solution
Thanks to max. Now I was able to create a control that try to fit the whole text in one line. If someone is interested, here's the code:
Public Class AutosizeLabel
Inherits System.Windows.Forms.Label
Public Overrides Property Text() As String
Get
Return MyBase.Text
End Get
Set(ByVal value As String)
MyBase.Text = value
ResetFontToDefault()
CheckFontsizeToBig()
End Set
End Property
Public Overrides Property Font() As System.Drawing.Font
Get
Return MyBase.Font
End Get
Set(ByVal value As System.Drawing.Font)
MyBase.Font = value
currentFont = value
CheckFontsizeToBig()
End Set
End Property
Private currentFont As Font = Me.Font
Private Sub CheckFontsizeToBig()
If Me.PreferredWidth > Me.Width AndAlso Me.Font.SizeInPoints > 0.25! Then
MyBase.Font = New Font(currentFont.FontFamily, Me.Font.SizeInPoints - 0.25!, currentFont.Style, currentFont.Unit)
CheckFontsizeToBig()
End If
End Sub
Private Sub ResetFontToDefault()
MyBase.Font = currentFont
End Sub
End Class
Could need some fine tuning (make the step size and the minimum value configurable with designer visible Properties) but it works pretty well for the moment.
Remarks. Set AutoEllipsis to true to display text that extends beyond the width of the Label in a tooltip when the user passes over the control with the mouse. If AutoSize is true , the label will grow to fit the text and an ellipsis will not appear.
On the tab "Properties" just click on the arrow to show all controls and click on the label you want, this will automatically select the label on your form..
In Windows Forms, Label control is used to display text on the form and it does not take part in user input or in mouse or keyboard events. The Label is a class and it is defined under System.Windows.Forms namespace.
private static bool IsShowingEllipsis(Label label)
{
return label.PreferredWidth > label.Width;
}
