Gets the error description for a column, specified by name.
public:
System::String ^ GetColumnError(System::String ^ columnName);public string GetColumnError(string columnName);member this.GetColumnError : string -> stringPublic Function GetColumnError (columnName As String) As StringParameters
- columnName
- String
The name of the column.
Returns
The text of the error description.
Examples
The following example sets an error description for a specified DataRow.
private void SetColError(DataRow row, int columnIndex)
{
string errorString = "Replace this text.";
// Set the error for the specified column of the row.
row.SetColumnError(columnIndex, errorString);
}
private void PrintColError(DataRow row, int columnIndex)
{
// Print the error of a specified column.
Console.WriteLine(row.GetColumnError(columnIndex));
}
Private Sub SetColError(ByVal row As DataRow, _
byVal columnIndex As Integer)
Dim errorString As String = "Replace this text."
' Set the error for the specified column of the row.
row.SetColumnError(columnIndex, errorString)
End Sub
Private Sub PrintColError( _
ByVal row As DataRow, byVal columnIndex As Integer)
' Print the error of a specified column.
Console.WriteLine(row.GetColumnError(columnIndex))
End Sub
Remarks
Use the SetColumnError method to set column errors.
To determine whether any errors exist for the columns collection, use the HasErrors method. Consequently, you can use the GetColumnsInError method to retrieve all the columns with errors.
To clear all errors for the columns collection, use the ClearErrors method.

- column
- DataColumn
A DataColumn.
Returns
The text of the error description.
Examples
The following example sets an error description for a specified DataRow.
private void SetColError(DataRow row, int columnIndex)
{
string errorString = "Replace this text.";
// Set the error for the specified column of the row.
row.SetColumnError(columnIndex, errorString);

private void PrintColError(DataRow row, int columnIndex)
{
// Print the error of a specified column.
Console.WriteLine(row.GetColumnError(columnIndex));
}
Private Sub SetColError(ByVal row As DataRow, _
byVal columnIndex As Integer)
Dim errorString As String = "Replace this text."
' Set the error for the specified column of the row.
row.SetColumnError(columnIndex, errorString)
End Sub
Private Sub PrintColError( _
ByVal row As DataRow, byVal columnIndex As Integer)
' Print the error of a specified column.
Console.WriteLine(row.GetColumnError(columnIndex))
End Sub
Remarks
Use the SetColumnError method to set column errors.
To determine whether any errors exist for the columns collection, use the HasErrors method. Consequently, you can use the GetColumnsInError method to retrieve all the columns with errors. Alternatively, the GetErrors method of the DataTable returns all rows with errors.
To clear all errors for the columns collection, use the ClearErrors method.
