[ VB ]
Overloads Public Sub SetColumnError ( _
ByVal columnIndex As Integer, _
ByVal error As String _
)
[ C# ]
void SetColumnError (
int columnIndex,
string error
);
[ C++ ]
public: void SetColumnError (
int columnIndex,
String* error
);
[ JScript ]
public function SetColumnError (
columnIndex : int,
error : String
);
- columnIndex
- The zero-based index of the column.
- 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, int colIndex ) {
string errorString = "Your error text here.";
// set the error for the specified column of the row.
myRow.SetColumnError ( colIndex, errorString );
}
Private Sub SetColError ( ByVal myRow As DataRow, ByVal colIndex As Integer )
Dim errorString As String = "Your error text here."
' set the error for the specified column of the row.
myRow.SetColumnError ( colIndex, errorString )
