在另一个子控件中使用子控件属性 [英] using child control properties in another child controls

问题描述

我正在使用TableLayoutPanel作为表。每个表格单元格都有面板控件。一些Panel控件中有Label控件。



当我想使用PANEL控件时，我可以使用

  Dim  ipanel  as  panel =  TryCast （TableLayoutPanel.Getcontrolfromposition（i，j），panel）
 ipanel.backcolor = color.gray ' 例如 

我可以在for-next语句中使用所有这样的CHILD PANEL属性。但是，TableLayoutPanel中的一些子PANEL控件中还有其他Label控件。



如何在此处使用LABEL控件属性？



我必须用于下一次扫描TableLayoutPanel的所有单元格。因此，我需要达到

ilable = ipanel.controls （我知道写这里不正确，只是为了解释我需要的东西）



提前致谢

解决方案

好的。我找到了解决方案:)

  Dim  c  As  Control =  Me  .TableLayoutPanel1.GetControlFromPosition（i，j）
 如果 c.HasChildren（）那么 
  Dim  pt  As  Point 
  Dim  L  As  Control = c。 GetChildAtPoint（pt）
  L.Text  = c.Tag 
 结束 如果 

I'm using TableLayoutPanel as table. Each Table cells has panel controls. Some Panel controls has Label control in it.

When I want to use PANEL controls, I can use

Dim ipanel as panel = TryCast(TableLayoutPanel.Getcontrolfromposition(i,j),panel)
ipanel.backcolor = color.gray ' for example

I can use all CHILD PANEL properties like this in for-next statements. But also, some of child PANEL Controls in the TableLayoutPanel, has other Label controls in it.

How can I use the LABEL controls properties here as?

I have to use for next to scan for all cells of TableLayoutPanel. therefore, I need to reach as
ilable = ipanel.controls (I know writing here is not correct, just to explain What I needed)

Thanks in advance

解决方案

Ok. I found solution :)

Dim c As Control = Me.TableLayoutPanel1.GetControlFromPosition(i, j)
If c.HasChildren() Then
    Dim pt As Point
    Dim L As Control = c.GetChildAtPoint(pt)
    L.Text = c.Tag
End If
