在Windows窗体中多选择texbox集合并更改属性 [英] multi select texbox Collections in windowsform and change Attribute

问题描述

你好

我有多个具有不同名称的文本框，我想更改属性.enable = true;

并使用foreach或
我该怎么办?

相同

hello

i have multi text box with different name i want to change attribute .enable=true;

and use foreach or for
how can i ?

same

foreach (Control tx in this.Controls)??????
           {
                Type c=tx.GetType();
                if (c == typeof(TextBox))
                   ????????????? i dont know

           }

例如txt1.enable = true;

for example txt1.enable=true;

推荐答案

在这种情况下，我想花费更多的时间和精力来获得可以重新获得的东西.用过的.而且，我希望可以在任何特定种类的控件上进行操作的东西，并且可以在不对控件内的控件进行递归检查的情况下运行:

In this case, I''d want to invest a little more time and effort to get something that can be re-used. And, I''d want something that could operate on any particular kind of control, and that could be run with and without recursive checking for controls within controls:

private void SetControlsEnabledProperty(bool isEnabled, bool isRecursive, string typeToCheck, Control.ControlCollection theControls)
    {
        foreach (Control theControl in theControls)
        {
            // is there a better way to handle the
            // the type checking required here ?
            if (theControl.GetType().Name == typeToCheck)
            {
                theControl.Enabled = isEnabled;
            }
            else
            {
                if (isRecursive && theControl.HasChildren)
                {
                    SetControlsEnabledProperty(isEnabled, isRecursive, typeToCheck, theControl.Controls);
                }
            }
        }
    }
}

我可能会像这样调用此函数以迭代窗体中的所有控件，并将每个TextBox的Enabled属性设置为true:

I might call this function like this to iterate all the Controls in a Form, and set every TextBox''s Enabled property to true:

SetControlsEnabledProperty(true, true, "TextBox", this.Controls);

foreach (Control control in this.Controls)
{
    TextBox textBox = control as TextBox;
    if (!object.ReferenceEquals(null, textBox))
        textBox.Enabled = true;
}
