FindControl不行!

Answer 2

foreach (CheckBox cb in Form.Controls)
            {
                if (cb.Checked)
                {
                    selectTypeCount++;
                }
            }
            if (selectTypeCount == 0)
            {
                error.SetError(groupBox1, "请至少选择一种图片类型");
            }
            else
            {
                error.SetError(groupBox1, "");
            }本人的程序代码。我用的是CheckBox,你用的是CheckedListBox，我想这个不难改成你希望的代码。

Answer 4

我以前是这样解决的，改变控件的外观，稍加修改应该适用于你的要求，不知道有没有更好的办法。foreach (Control c in this.Controls)
{
    string s = c.GetType().ToString();
    switch (s)
    {
        case "System.Windows.Forms.Button":
            {
                Button b = (Button)c;
                if (b.FlatStyle == FlatStyle.Flat)
                {
                    b.FlatStyle = FlatStyle.Standard;
                }
                else
                {
                    b.FlatStyle = FlatStyle.Flat;
                }
                break;
            }
        case "System.Windows.Forms.TextBox":
            {
                TextBox t = (TextBox)c;
                if (t.BorderStyle == BorderStyle.FixedSingle)
                {
                    t.BorderStyle = BorderStyle.Fixed3D;
                }
                else
                {
                    t.BorderStyle = BorderStyle.FixedSingle;
                }
                break;
            }
    }
}

Answer 6

如果你要使用CheckedListBox,必须转换类型
if (control is CheckedListBox)
                {
                    //转换类型
                    CheckedListBox cbx = (CheckedListBox)control;
                    //后面就可以正常使用了
                    this.m_ctrlCount++;
                    this.textBox1.Text = this.m_ctrlCount.ToString("d");
                }// end if
