[ VB ]
Overloads Public Sub SetColumnError ( _
   ByVal column As DataColumn, _
   ByVal error As String _
)

[ C# ]
void SetColumnError (
   DataColumn column,
   string error
);

[ C++ ]
public: void SetColumnError (
   DataColumn* column,
   String* error
);

[ JScript ]
public function SetColumnError (
   column : DataColumn,
   error : String
);

column

The DataColumn to set the error description for.

error

The error description.

To examine error descriptions, use the GetColumnError method.

To determine if any errors exist for the columns collection, use the HasErrors method. Consequently, you can use the GetColumnsInError method to retrieve all of the columns with errors.

To set a custom error description on the whole row, use the RowError property.

To clear all errors for the columns collection, use the ClearErrors method.

The following example sets an error description for a specified DataRow.

private void SetColError ( DataRow myRow, DataColumn column ) {
   string errorString = "Your error text here.";
   // set the error for the specified column of the row.
   myRow.SetColumnError ( column, errorString );
}

Private Sub SetColError ( ByVal myRow As DataRow, ByVal column As DataColumn )
   Dim errorString As String = "Your error text here."
   ' set the error for the specified column of the row.
   myRow.SetColumnError ( column, errorString )
End Sub
