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 Sub 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 Sub GetAllErrs(ByVal row As DataRow)
    ' Declare an array variable for DataColumn objects.
    Dim colArr() As DataColumn 

    ' If the Row has errors, check use GetColumnsInError.
    Dim i As Integer
    If row.HasErrors Then 
       ' Get the array of columns in error.
       colArr = row.GetColumnsInError()
       For i = 0 to colArr.GetUpperBound(0)
          ' Insert code to fix errors on each column.
       Next i

    ' Clear errors after reconciling.
    End If
 End Sub
