Xaml.cs

The code below demonstrates how to dynamically adjust the height of the SfDataGrid based on SfBottomSheet size changes.

private void Button_Clicked(object sender, EventArgs e)
{
    double screenHeight = DeviceDisplay.MainDisplayInfo.Height / DeviceDisplay.MainDisplayInfo.Density;

    double ratio = CalculateExpandRatio(bottomSheet.BottomSheetContent, screenHeight);

    bottomSheet.HalfExpandedRatio = ratio;

    bottomSheet.Show();
}

public double CalculateExpandRatio(View bottomSheetContent, double screenHeight)
{

    double contentHeight = 0;

    contentHeight = bottomSheetContent.Measure(double.PositiveInfinity, double.PositiveInfinity).Height;

    // Define minimum and maximum ratios

    double minRatio = 0.4;

    double maxRatio = 0.9;


    // Calculate the ratio based on content height relative to screen height

    double calculatedRatio = contentHeight / screenHeight;


    // Ensure ratio stays within platform-specific bounds

    double finalRatio = Math.Clamp(calculatedRatio, minRatio, maxRatio);

    return finalRatio;

}
