DataRow.GetColumnError (String)

Gets the error description for a column, specified by name.

[Visual Basic]
Overloads Public Function GetColumnError( _
   ByVal columnName As String _
) As String
[C#]
public string GetColumnError(
   string columnName
);
[C++]
public: String* GetColumnError(
   String* columnName
);
[JScript]
public function GetColumnError(
   columnName : String
) : String;

Parameters

columnName
The name of the column.

Return Value

The text of the error description.

Remarks

Use the SetColumnError method to set column errors.

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.

To clear all errors for the columns collection, use the ClearErrors method.

Example [Visual Basic]

The following example sets and gets the error description for a new column in an existing System.WinForms.DataGrid control's DataTable.

[Visual Basic]

Dim myRow As DataRow
Dim t As DataTable
t = DataGrid1.DataSource.DataTable
myRow = t.NewRow
Dim ErrorString As String
ErrorString = "Replace this text."
' Use DataColumn.Contains to ensure the column exists
If myRow.DataTable.Columns.Contains("id") Then
   myRow.SetColumnError "id", ErrorString
   Console.WriteLineDebug(myRow.GetColumnError("id"))
   ' Add the row
   t.Rows.Add(myRow)
End If
