问题
How can I convert int to System.Windows.GridLength in VB, NET so that I can set the height of a grid row in Silverlight (xaml).
In xaml file:
<RowDefinition Height="0" x:Name="rowerror" />
In VB.NET:
rowerror.Height = CType(30, System.Windows.GridLength)
This as I wrote in VB.NET. I know I'm wrong, but how do you do if the int to System.Windows.GridLength so that the height of the "rowerror" whether that be 30?
回答1:
rowerror.Height = new GridLength(30)
回答2:
The MSDN Documentation provides an example of this using a GridLengthConverter..
Dim myGridLengthConverter As System.Windows.GridLengthConverter = New System.Windows.GridLengthConverter()
...
rowerror.Height = CType(myGridLengthConverter.ConvertFromString("30"), GridLength)
