DataGrid ColumnHeader PreviewLeftMouseButtonDown事件限制

Question

我有这样的数据栏标题：

<datagridtemplatecolumn.headertemplate>
    <datatemplate previewmouseleftbuttondown="TextBlock_DocumentsClick">
        <stackpanel orientation="Vertical">
            <textblock text="Doctor Name" previewmouseleftbuttondown="TextBlock_ReceptionsClick" name="DoctorName" />
            <textbox name="SearchReceptionDoctor" width="120" tag="DoctorName" text="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.RecDoctorNameFilter, UpdateSourceTrigger=PropertyChanged, Mode=TwoWay}">
                <textbox.inputbindings>
                    <keybinding key="Enter" command="{Binding RelativeSource={RelativeSource Mode=FindAncestor, AncestorType={x:Type DataGrid}}, Path=DataContext.FilterReceptionsCommand}" commandparameter="{Binding Tag, ElementName=SearchReceptionDoctor}" />
                </textbox.inputbindings>
            </textbox>
        </stackpanel>
    </datatemplate>
</datagridtemplatecolumn.headertemplate>

现在它运行良好，唯一的问题是，当我单击文本框时，我希望限制事件触发。是否有方法检查是否已单击文本框并防止触发事件的功能？以下是我的事件在代码后面的样子：

private void TextBlock_BookingsClick(object sender, MouseButtonEventArgs e)
{
    try
    {
        (this.DataContext as PatientViewModel).ColumnName = (sender as TextBlock).Name.ToString();
        (this.DataContext as PatientViewModel).PatientTabBookingsSorting();
    }
    catch (Exception ex)
    {
        PanLogger.Log(LogLevel.Error, String.Format("Bookings tab datagrid text block click event failed! \nReason: {0} \nStackTrace: {1} \nInnerException", ex.Message, ex.StackTrace, ex.InnerException));
    }
}

Answer 1

尝试OriginalSource属性MouseButtonEventArgs --这将为您提供发生事件的确切控制

Answer 2

我将得到发件人的类型，并检查这是否是一个文本框。
