Winforms RadPageView查找控件

本文关键字：控件 查找 RadPageView Winforms | 更新日期: 2023-09-27 17:51:17

我在Winform应用程序的RadPageView控件中嵌套了控件。RadPageView有一个子RadPageViewPage。这两个控件都在表单上，但是一个是选项卡控件，在选项卡控件中动态添加了其他一些控件。如何在单击按钮时找到并更改动态生成的选项卡控件内的文本框的值? 

public Form1()
    {
        InitializeComponent();
        TabControl tb = new TabControl();
        tb.Width = 500;
        TabPage tp = new TabPage("Tab 1");
        Label lb = new Label();
        lb.Text = "Test";
        lb.Location = new Point(10, 10);
        TextBox txt = new TextBox();
        txt.Text = "Textbox";
        txt.Location = new Point(200, 10);
        tp.Controls.Add(lb);
        tp.Controls.Add(txt);
        tb.Controls.Add(tp);
        radPageViewPage1.Controls.Add(tb);

    }
    private void button1_Click(object sender, EventArgs e)
    {
    }

Winforms RadPageView查找控件

我在网上找到了这个例子，它运行得很好。

public Form1()
    {
        InitializeComponent();
        TabControl tb = new TabControl();
        tb.Width = 500;
        TabPage tp = new TabPage("Tab 1");
        Label lb = new Label();
        lb.Text = "Test";
        lb.Name = "lblTest";
        lb.Location = new Point(10, 10);
        TextBox txt = new TextBox();
        txt.Text = "Textbox";
        txt.Name = "txtName";
        txt.Location = new Point(200, 10);
        tp.Controls.Add(lb);
        tp.Controls.Add(txt);
        tb.Controls.Add(tp);
        radPageViewPage1.Controls.Add(tb);

    }
    private void button1_Click(object sender, EventArgs e)
    {
        var crl = FindControl("txtName");
        MessageBox.Show(crl.Text);
    }
    Control FindControl(string target)
    {
        return FindControl(this, target);
    }
    static Control FindControl(Control root, string target)
    {
        if (root.Name.Equals(target))
            return root;
        for (var i = 0; i < root.Controls.Count; ++i)
        {
            if (root.Controls[i].Name.Equals(target))
                return root.Controls[i];
        }
        for (var i = 0; i < root.Controls.Count; ++i)
        {
            Control result;
            for (var k = 0; k < root.Controls[i].Controls.Count; ++k)
            {
                result = FindControl(root.Controls[i].Controls[k], target);
                if (result != null)
                    return result;
            }
        }
        return null;
    }
