C# Class Argentini.Halide.H3DataRow

The Halide H3DataRow class is used to load and manipulate an entire row from a database table/view/SP, and uses Halide.DatabaseRow and Halide.DatabaseItem classes as children.

Note that H3DataRow is case-sensitive! So when you use methods like "Exec" which send H3DataRow column values back to a stored procedure, the column names must match the stored procedure names, including case, which also must match the destination table names, including case.

In addition, the "Exec" method will not work with stored procedures that use OUTPUT parameters.

Méthode	Description
AddColumn ( String columnName, String columnValue ) : System.Boolean	Add a column to the data set in memory. This is useful when stored procedures used for saving data require optional parameters.
ColumnExists ( String columnName ) : System.Boolean	Determine if a column of a specific name exists in the data set.
DeleteColumn ( String columnName ) : System.Boolean	Delete a column from the data set in memory.
DeleteColumn ( int index ) : System.Boolean	Delete a column from the data set in memory.
EmailSanitize ( String columnName ) : void	Strips specific field data of dangerous email header text.
EmailSanitize ( int columnIndex ) : void	Strips specific field data of dangerous email header text.
Exec ( String spName ) : String	Execute the specified stored procedure. Parameters used in the stored procedure must match column names in the currently loaded data row. If so, this method will automatically send the appropriate data to the procedure. This method is useful for saving the record back to the database, marking a record for deletion, and more. This method assumes that the stored procedure returns a value. If it does not, the procedure will execute, but an exception will be thrown.
Exec ( String spName, System.Boolean sendAll ) : String	Execute the specified stored procedure. Parameters used in the stored procedure must match column names in the currently loaded data row. If so, this method will automatically send the appropriate data to the procedure. This method is useful for saving the record back to the database, marking a record for deletion, and more. This method assumes that the stored procedure returns a value. If it does not, the procedure will execute, but an exception will be thrown.
Exec ( String spName, System.Boolean sendAll, System.Boolean returnsValue ) : String	Execute the specified stored procedure. Parameters used in the stored procedure must match column names in the currently loaded data row. If so, this method will automatically send the appropriate data to the procedure. This method is useful for saving the record back to the database, marking a record for deletion, and more.
GetPrimarykeyName ( ) : String	Get the primary key column name.
H3DataRow ( Control containerControl ) : System	Instantiate the class with a Control object reference. This is used to read in a group of controls and their values from within the parent control. If using the "Exec()" method, this allows the developer to easily save a submitted form to a database without having to manually process and pass the stord procedure parameters. Uses the default connection string "Halide".
