我有一个当前通过鼠标单击更改文本的字段。此字段位于我报告的多个页面上，但单击它只会更改该页面的文本。这是我的代码：

 const string sShowDetail2 = "Show Cumulative";
 const string sHideDetail2 = "Hide Cumulative";
 ArrayList expandedValues2 = new ArrayList();


    // This function returns a value indicating whether a certain  
    // category's details should be expanded. 

    bool ShouldShowDetail2(int CategoryID)
    {
        return expandedValues2.Contains(CategoryID);

    }



    private void lbShowHide2_BeforePrint(object sender, PrintEventArgs e)
    {
        XRLabel label = (XRLabel)sender;

        if (ShouldShowDetail2((int)label.Tag))
        {
            label.Text = sHideDetail2;
        }
        else
        {
            label.Text = sShowDetail2;
        }
    }

    private void lbShowHide2_PreviewClick(object sender, PreviewMouseEventArgs e)
    {
        // Obtain the category's ID stored in the label's Tag property. 
        int index = (int)e.Brick.Value;

        // Determine whether the current category's details are shown. 
        bool showDetail2 = ShouldShowDetail2(index);

        // Toggle the visibility of the category's details. 
        if (showDetail2)
        {
            expandedValues2.Remove(index);
        }
        else
        {
            expandedValues2.Add(index);
        }

现在我有另一个字段，我需要在点击时简单地切换该字段的所有实例（每个页面）。我不需要它来读取我单击的特定标签的标签，因为它会同时更改所有标签。我的问题是我不知道如何在鼠标点击时让它们全部改变。如何修改上面的代码以更改标签的所有实例？

这是你可以尝试的东西

private void ChangeXRLabels(Control control)
{
    foreach(Control childControl in control.Controls)
    {
         XRLabel label = childControl as XRLabel;
         if(label != string.Empty)
            label.Text = "Your Text Value goes Here";
         else if(childControl.Controls.Count > 0)
             ChangeXRLabels(childControl);
    }
}
