DataRow.RowError Property

Gets or sets the custom error description for a row.

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

public string RowError { get; set; }

Property Value

Type: System.String
The text describing an error.

Uses the HasErrors property to first determine whether a DataRow contains errors.

The following example sets error text for ten rows of a table displayed in a DataGrid control.

private void SetRowErrors(DataTable table)
{
    // Set error text for ten rows.  
    for(int i = 0; i < 10; i++)
    {
        // Insert column 1 value into each error.
        table.Rows[i].RowError = "ERROR: " 
            + table.Rows[i][1];
    }
    // Get the DataSet for the table, and test it for errors.
    DataSet dataSet = table.DataSet;
    TestForErrors(dataSet);
}

private void TestForErrors(DataSet dataSet)
{
    // Test for errors. If DataSet has errors, test each table. 
    if(dataSet.HasErrors)
    {
        foreach(DataTable tempDataTable in dataSet.Tables)
        {
            // If the table has errors, then print them. 
            if(tempDataTable.HasErrors) 
                PrintRowErrs(tempDataTable);
        }
        // Refresh the DataGrid to see the error-marked rows.
        dataGrid1.Refresh();
    }
}

private void PrintRowErrs(DataTable table)
{
    foreach(DataRow row in table.Rows)
    {
        if(row.HasErrors) 
        {
            Console.WriteLine(row.RowError);
        }
    }
}
