如何在devexpress中搜索表单上的所有控件（包括子报表）

发布于 2024-12-19 16:38:47 字数 211 浏览 0 评论 0原文

我有一份开发快报。我想搜索报告上的所有控件。

Windows 窗体中的正常约定是：

foreach (Control c in Control.ControlCollection)
{
         ........
}

不幸的是，这在 Dev Express 窗体中不起作用。有什么解决办法吗？

谢谢

I have a dev express report. I want to search for all controls on the report.

The normal convension in windows forms would be:

foreach (Control c in Control.ControlCollection)
{
         ........
}

Unfortunately this will not work in Dev Express form. Any solutions?

Thanks

有很多这样的问题，涉及在报告中查找控件或在鼠标悬停时突出显示单元格等。

xrLabel1.Text = ((XRLabel)((XtraReport)xrSubreport1.ReportSource).FindControl("xrLabel1", false)).Text;

子报表控件 - 在此处检查附加示例

Q274540.XtraReport1)).Detail.Controls
    For i As Integer = 0 To collection.Count - 1
        If TypeOf collection(i) Is XRLabel Then
            If (CType(collection(i), XRLabel)).DataBindings.Count <> 0 Then
                'your code here
            End If
        End If
