XMLNode.ValidationError 事件 (2007 系統)
更新：2007 年 11 月
會在 XMLNode 控制項出現驗證錯誤時發生。
命名空間： Microsoft.Office.Tools.Word
組件： Microsoft.Office.Tools.Word.v9.0 (在 Microsoft.Office.Tools.Word.v9.0.dll 中)
語法
Public Event ValidationError As EventHandler
Dim instance As XMLNode
Dim handler As EventHandler
AddHandler instance.ValidationError, handler
public event EventHandler ValidationError
範例
下列程式碼範例使用 SetValidationError 方法，設定 XMLNode 的自訂驗證錯誤訊息。如果 XMLNode 不會進行驗證，則 ValidationError 事件的事件處理常式會顯示自訂驗證錯誤訊息。這個範例假設目前文件包含兩個名為 CustomerAddress1Node 和 CustomerZipNode 的 XMLNode 物件，這兩個物件會對應到具有整數資料型別的結構描述項目。
Private Sub XMLNodeValidationError()
' Set custom error message for Address1 element.
Dim errorText As String = Me.CustomerAddress1Node.BaseName & _
" element must be an integer."
Dim objErrorText As Object = CType(errorText, Object)
Me.CustomerAddress1Node.SetValidationError( _
Word.WdXMLValidationStatus.wdXMLValidationStatusCustom, _
objErrorText, False)
' This does not raise a validation error.
Dim val As Integer = 22222
Me.CustomerZipNode.NodeText = val.ToString()
' This raises a validation error.
Me.CustomerAddress1Node.NodeText = "Seventeen Hundred Twenty One"
End Sub
Private Sub CustomerNode_ValidationError(ByVal sender As Object, _
ByVal e As EventArgs) Handles CustomerZipNode.ValidationError, _
CustomerAddress1Node.ValidationError
Dim tempNode As Microsoft.Office.Tools.Word.XMLNode = CType(sender, _
Microsoft.Office.Tools.Word.XMLNode)
MsgBox("Error: " & tempNode.ValidationErrorText(False))
End Sub
private void XMLNodeValidationError()
{
// Set custom error message for Address1 element.
string errorText = this.CustomerAddress1Node.BaseName +
" element must be an integer.";
object objErrorText = (object)errorText;
this.CustomerAddress1Node.SetValidationError(
Word.WdXMLValidationStatus.wdXMLValidationStatusCustom,
ref objErrorText, false);
// Attach validation event handlers.
this.CustomerZipNode.ValidationError +=
new EventHandler(CustomerNode_ValidationError);
this.CustomerAddress1Node.ValidationError +=
new EventHandler(CustomerNode_ValidationError);
// This does not raise a validation error.
int val = 22222;
this.CustomerZipNode.NodeText = val.ToString();
// This raises a validation error.
this.CustomerAddress1Node.NodeText =
"Seventeen Hundred Twenty One";
}
void CustomerNode_ValidationError(object sender, EventArgs e)
{
Microsoft.Office.Tools.Word.XMLNode tempNode =
(Microsoft.Office.Tools.Word.XMLNode)sender;
MessageBox.Show("Error: " + tempNode.ValidationErrorText[false]);
}
