当在 XMLNode 控件中存在验证错误时发生。
命名空间： Microsoft.Office.Tools.Word
程序集： Microsoft.Office.Tools.Word.v9.0（在 Microsoft.Office.Tools.Word.v9.0.dll 中）
语法
声明
Public Event ValidationError As EventHandler
用法
Dim instance As XMLNode
Dim handler As EventHandler
AddHandler instance.ValidationError, handler
public event EventHandler ValidationError
示例
下面的代码示例使用 SetValidationError 方法为 XMLNode 设置自定义验证错误信息。ValidationError 事件的事件处理程序会在 XMLNode 未验证时显示该自定义验证错误信息。此示例假定当前文档包含名为 CustomerAddress1Node 和 CustomerZipNode 的两个 XMLNode 对象，这两个对象映射到整数数据类型的架构元素。
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]);
}
