C#/WPF Grid MaxWidth in relation to screen resolution

I've got 2 Columns that are divided by a GridSplitter. And I want to set the MaxWidth of the columns in percentage (e.g. 5*) but it doesn't work. Is there any other way to do it?

<Grid.ColumnDefinitions>
      <ColumnDefinition Width="6*"  />
      <ColumnDefinition Width="Auto"  />
</Grid.ColumnDefinitions>
<GridSplitter ResizeDirection="Columns"
              Grid.Column="0"
              HorizontalAlignment="Right"
              VerticalAlignment="Stretch"
              Height="auto"
              Background="#c1c1c1"
              BorderBrush="#c1c1c1"
              BorderThickness="1"/>
Solution

  • If you check the MSDN documentation for ColumnDefinition, MinWidth and MaxWidth are of type double, not like Width property, which is of type GridLength - that's why it supports Auto, * as valid values for Widtth. So, Specifying MinWidth, MaxWidth interms of percentages is not a straight forward thing.

    However, you could write a Converter, which can take Auto, * as input values and do the math and then set a valid value for MaxWidth.
