תמיד תופס הרבה מקום וזמן להגדיר שורות ועמודות בתוך פקד Grid ב-wpf
ראיתי מה הם עשו ב-Avalonia ותפסתי רעיון לעשות לעצמי Class שיעשה אותו הדבר.
ברגיל צריך לעשות כך:
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="Auto"/>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="2*"/>
</Grid.ColumnDefinitions>
<Grid.RowDefinitions>
<RowDefinition Height="Auto"/>
<RowDefinition Height="*"/>
<RowDefinition Height="Auto"/>
</Grid.RowDefinitions>
<\Grid>
עם ה-class שיצרתי אפשר לעשות כך:
<Grid local:GridSetup.Columns="Auto,*,2*" local:GridSetup.Rows="Auto,*,Auto">
