DataRow.GetColumnError Method (DataColumn)

Gets the error description of the specified DataColumn.

Namespace: System.Data
Assembly: System.Data (in system.data.dll)

public string GetColumnError (
	DataColumn column
)
public String GetColumnError (
	DataColumn column
)
public function GetColumnError (
	column : DataColumn
) : String

Parameters

column

A DataColumn.

Return Value

The text of the error description.

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.

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));
