How to Adjust the Height of .NET MAUI DataGrid?

This article demonstrates how to dynamically adjust the height of the .NET MAUI DataGrid based on size changes in the SfBottomSheet. This approach ensures that the DataGrid adapts to the visible space, improving visual adaptability.

Xaml.cs
The code 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;

}
