Windows窗体在运行时动态添加文本框 [英] windows form adding textbox at runtime dynamically

问题描述

大家好，

我可以使用以下代码在运行时动态添加页面上的文本框:-

hi all ,

I am able to add textbox on page at run time dynamically using code like:-

Textbox objtxtBox = new Textbox();
objtxtBox.name = "txtFName";

我可以在单击按钮时显示新的文本框，但是我想在单击另一个按钮时获得该文本框的值，但是无法使用相同的文本框名称属性获取该值.

I am able to display new textbox on button click but i want to get the value of that textbox on the click o another button, but unable to get the value using same textbox name property.


how to do this.

推荐答案

创建控件后，是否将控件添加到Form.Controls集合中?

Did you add the control to the Form.Controls collection after you created it?

您可以通过以下代码获取文本框值:

You can get your text box value by the following code:

Control cc = this.Controls.Find(txtFName, true).First();
string value = cc.Text;
