Hello,

This is related to the initialization process of the Maui control. If you read the X and Y values ​​directly in the page's construction method, they will be 0 because the control has not yet been assigned a position.

After the control is placed on the page, you can read its X, Y. This event corresponds to the SizeChanged event of the control. Please refer to the following code.

TheView.SizeChanged += (s, e) =>
{
    Console.WriteLine(TheView.X.ToString());
};

Best Regards,

Alec Liu.
