Problem:

In .Net Winforms how can a user hide controls when a checkbox is checked ?

Resolution:

In WinForms there is a CheckedChanged event for a CheckBox. You can use this and the "Checked" property of the checkbox to hide controls as required.

The simplest way to hide a control is by setting the "Visible" property of a control to false.

Some example code that does this is:-

       method-id.  "cboxHide_CheckedChanged" final private.

       linkage section.

       01 sender System-Object.

       01 e System-EventArgs.

       procedure division using by value  sender e.

           if self::"cboxHide"::"Checked"

               set self::"txtBox1"::"Visible" to true

               set self::"lblHide"::"Visible" to true

           else

               set self::"txtBox1"::"Visible" to false

               set self::"lblHide"::"Visible" to false

           end-if

       end method "cboxHide_CheckedChanged".

As you can see it hides/shows a textbox and label as required.
