Dynamically Calculate Control Dimension at UI

Calculate the dimension of controls at UI in term of rows*columns. This accepts parent container width/height and number of controls to draw. You may also provide what ratio you need for controls.

/// Calculate control dimension as per parent size and required ratio

/// param name="ParentWidth">Parent control width

/// param name="ParentHeight">Parent control height

/// param name="TotalControls">Total control

/// param name="RatioX">X ratio of control to maintain

/// param name="RatioY">Y ratio of control to maintain

/// param name="TotalColumns">get columns

/// param name="TotalRows">get rows
