WinForms Databinding
The databinding in WinForms is not so advanced like the databinding in WPF, but it is possible.
The data object on which the controls content can be bound (usually called ViewModel in MVVM terms) needs to implement the INotifyPropertyChanged
interface.
As usual, it requires at least one line of code for every field:
oTextBox:Bindings:Add( "Text", oViewModel, "PropertyName" )
where Text
stands for the property of the TextBox on which the ViewModel field has to be bound, and FieldName
stands for the name of the property in the ViewModel that contains the desired value.
It is very easy to implement name based binding in WinForms. You need a similar method of ther following in your window:
method Use( oViewModel as INotifyPropertyChanged ) as void local oControls as System.Windows.Forms.Control.ControlCollection local oTextBox as TextBox oControls := self:Controls foreach oControl as Control in oControls do case case oControl is TextBox oTextBox := ( TextBox ) oControl oTextBox:DataBindings:Add( "Text", oViewModel, oTextBox:Name ) endcase next return
and then you can combine your form (or View as in MVVM) with a simple statement:
oForm:Use( oViewModel )
Of course you should enhance your method to implement databinding also for the other types of controls you use, and you should put them in your windows base class from which all your forms/Views will be inherited.
