DataRow.ClearErrors Method

Clears the errors for the row. This includes the RowError and errors set with SetColumnError.

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

public void ClearErrors()

Use SetColumnError and GetColumnError to set and return errors for individual columns.

Set the RowError property to set an error that applies to the whole row.

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.

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();
    }
}
