ClearErrors Method

DataRow.ClearErrors Method

Clears the errors for the row, including the RowError and errors set with SetColumnError.

[Visual Basic]
Public Sub ClearErrors()
[C#]
public void ClearErrors();
[C++]
public: void ClearErrors();
[JScript]
public function ClearErrors();

Remarks

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 if any errors exist for the columns collection, use the HasErrors method. Consequently, you can use the GetColumnsInError method to retrieve all of the columns with errors.

Example

[Visual Basic, C#, C++] The following example uses the HasErrors to check 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.

[Visual Basic] 
Private Sub GetAllErrs(ByVal myRow 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 myRow.HasErrors Then 
       ' Get the array of columns in error.
       colArr = myRow.GetColumnsInError()
       For i = 0 to colArr.GetUpperBound(0)
          ' Insert code to fix errors on each column.
          Console.WriteLine(colArr(i).ColumnName)
       Next i
    ' Clear errors after reconciling.
    myRow.ClearErrors()
    End If
 End Sub

[C#] 
private void GetAllErrs(DataRow myRow){
    // Declare an array variable for DataColumn objects.
    DataColumn[] colArr; 
    // If the Row has errors, check use GetColumnsInError.
    if(myRow.HasErrors){
       // Get the array of columns in error.
       colArr = myRow.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.
    myRow.ClearErrors();
    }
 }

[C++] 
private:
void GetAllErrs(DataRow* myRow){
    // Declare an array variable for DataColumn objects.
    DataColumn* colArr[]; 
    // If the Row has errors, check use GetColumnsInError.
    if(myRow->HasErrors){
       // Get the array of columns in error.
       colArr = myRow->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.
    myRow->ClearErrors();
    }
 }
