Create a Resize Manager - which Auto Adjust the Windows Forms and the controls and font size based on the Resolution of the system


In this article we are going to see the how to resize the winforms and there controls and the font size based on the resolution of the system. For that we are going to create a component which will support the design time , where we can supply the value to the component in design time. 

Resize Manager a component which will resize the form and the controls along with font size. For do this create a two properties in menu item which will accept the form as container and type of resolution at the design time.

For ex : if we design a winforms in 1024x768 then if we run this application in 1366x768 resolution system the resize manager will auto resize the forms and controls along with font size.

For this create  a  Form and drag the Four buttons inside a panel and now drag and drop the resize manager component from the toolbox and set the property of container with form and set the Resolution of current system.


Above image shows how the component sees in Toolbox of visual studio,


After drag and drop the component and select the properties, now the above image specifies what are the values to be specified, Set the Form1 in the Container and R1600X900 in Resolution.

Code for Resize Manager : 
    Resize Manager Reads the each and every control and set the value of size and font value from the base size.

To change the Percentage of current resolution change the values in Enum.

OUTPUT:

Form for R1024X768:



Form for R1366X768 :


From this article you can learn how to change the form size and the font size of each controls based on resolution.
