5. Main operation instructions I. public FieldBindingContent (string fieldName,
Object fieldValue,
Control bindingControl,
String bindingProperty,
Object defaultValue

)

Mainly through the FieldBindingContent class constructor to bind controls to this class (as a data source)

Parameter description:

/// <Summary>
/// Bind control attributes
/// </Summary>
/// <Param name = "fieldName"> the field name is bound to the tag value of the control to search for the control. </param>
/// <Param name = "fieldValue"> field value, bound to the specified property value of the Control </param>
/// <Param name = "bindingControl"> Control </param>
/// <Param name = "bindingProperty"> control property value </param>
/// <Param name = "defaultValue"> specify the default value of the Control </param>

Example: Read the above code, you know

II. public object GetProperty ()

Parameter description:

/// <Summary>
/// Obtain the property value bound to the current control
/// </Summary>
/// <Returns> returned attribute value </returns>

Example: Read the above code, you know

III. public void SetProperty (object Value );

Parameter description:

/// <Summary>
/// Set the property value of the bound control
/// </Summary>
/// <Param name = "Value"> data to be set </param>

Example: Read the above code, you know

IV. public void SetDefaultProperty ()

Parameter description:

/// <Summary>
/// Restore the initial value of the control Property
/// </Summary>

Example: Read the above code, you know

V. Main attribute display

Public bool AllowNull {get; set ;}
Public Control BindingControl {get; set;} // Control
Public string BindingProperty {get; set;} // property name of the control
Public object DefaultValue {get; set;} // default value of the control
Public object FieldValue {get; set;} // bound property value
Public string FieldName {get; set;} // name of the bound field
