DataRow.HasErrors Property

Gets a value that indicates whether there are errors in a row.

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

public bool HasErrors { get; }

Property Value

Type: System.Boolean
true if the row contains an error; otherwise, false.

HasErrors returns true if any DataColumn object in the row contains an error, or if the RowError property of the DataRow is not an empty string.

When validating data, you can set an error on any column in a row. Such a column, when displayed in the System.Windows.Forms.DataGrid control, is marked with a red exclamation point to signal to the user that the column is in error.

Use SetColumnError to set an error on any column.

Use the GetColumnError and GetColumnsInError methods to return columns with errors.

The ClearErrors method clears all errors for the row.

The following example uses the HasErrors to look for errors. If the row has errors, the GetColumnsInError method returns the array of columns with errors that can then be resolved. The ClearErrors method is then called to clear all errors.

private void GetAllErrs(DataRow row)
{
    // Declare an array variable for DataColumn objects.
    DataColumn[] colArr; 
    // If the Row has errors, check use GetColumnsInError. 
    if(row.HasErrors)
    {
        // Get the array of columns in error.
        colArr = row.GetColumnsInError();
        for(int i = 0; i < colArr.Length; i++)
        {
            // Insert code to fix errors on each column.
            Console.WriteLine(colArr[i].ColumnName);
        }
        // Clear errors after reconciling.
        row.ClearErrors();
    }
}
