PostCustomEditValidator assembly

When the constructor is called, the input arguments are loaded into the members of the base class ADEBaseEditFormPopUp. The custom class can use these members/properties for data manipulations:

• Form formThatOpenedThisForm

• string dalAlias

• BindingSource baseBindingSource

• string tableName

• string columnName

• Control ControlThatOpened

In the following example, the PostValidate method evaluates column values and marks errors in the RealTime database (RTDB) almdisturbance table configuration.

///<summary>Class for customized ADE Post Validation for almdisturbance table configuration </summary>

public partial class AlmdisturbancePostValidationPopUp: ADEBaseEditFormPopUp

{

string table_name = "";

DataSet ds;

DataTable dt;

DataRow dr;

/// <summary>

/// Constructor

/// </summary>

public AlmdisturbancePostValidationPopUp () : base()

{

InitializeComponent();

}
