通过按钮启用和禁用文本框？（asp.net）
[英]Enable and disable textbox through button?(asp.net)
问题描述
enter image description here My tutor gave me the following task: Create a form with 3 buttons(Save(Guardar) Edit(Editar) Delete(Eliminar) ).
在此处输入图像描述我的导师给了我以下任务：创建一个带有 3 个按钮的表单（Save(Guardar) Edit(Editar) Delete(Eliminar)）。
But my real question is this:但我真正的问题是：
I need to link my text box to my button allowing me to disable it and enable it at will but I can't conect them trough code.我需要将我的文本框链接到我的按钮，允许我禁用它并随意启用它，但我无法通过代码连接它们。
PS:If you answer this question try as much as you can to be specific about the terms you use since I've started learning asp.net a few days ago. PS：如果您回答这个问题，请尽可能详细说明您使用的术语，因为我几天前开始学习 asp.net。

First, you need to create the button event.首先，您需要创建按钮事件。 Double click to the button on your form, then the VB will create a button event automatically.双击窗体上的按钮，VB 会自动创建一个按钮事件。 Now, you can code.现在，您可以编码了。 For ie:对于即：
private void button1_Click(object sender, EventArgs e)
{
textBox1.Enabled = false;//Disable textbox1 on the form
}
