WPF xamdatagrid height + window size to content

Question

I have window with SizeToContent = "WidthAndHeight",startup location sets to manual. This window contains one grid with two rows: first with height "1*" and second with auto height. The first row contains xamdatagrid (infragistics) and the second contains OkCancel buttons.

after xamdatagrid initialization the window is been vertically stretched beyond visible area.

I don't want to bind max height to some calculation based on system parameters and other constants.

See: Window screenshot

code:

Answer 1

Don't use

SizeToContent="WidthAndHeight"

alone cause it will set the size of Window as its content. And your XamDataGrid has many records so Window will grow to a very large size. instead just delete that property then the content will be adjusted according to Window.

Or

give your Window some Height first (as try binding the Height of your Window to System.Windows.SystemParameters.PrimaryScreenHeight) then you can use SizeToContent and Window will not grow indefinitely. Also Grid row heights are irrelevant cause you have not given any fixed Height to any control or Grid.

This solves the problem.

Answer 2

First of all, the value 1* doesn't mean anything with the SizeToContent = "WidthAndHeight". If you change the "1*" to "Auto", you will have the same behavior. You should remove SizeToContent = "WidthAndHeight" and do this :

<Grid >
    <Grid.RowDefinitions>
        <RowDefinition Height="3*"/>
        <RowDefinition Height="1*"/>

    </Grid.RowDefinitions>
    <Grid>
        your list ..
    </Grid>
    <Grid Grid.Row="1">
        you buttons ..
    </Grid>
</Grid>

Your first row (list) will be (3/(3+1))% of the window size

The second (1/(3+1))%.
