If you're using ASP.NET WebForms you can add a Click event handler to the button to set the text box's text:

如果您使用的是ASP.NET WebForms,则可以向该按钮添加Click事件处理程序以设置文本框的文本:

protected void Button1_Click(object sender, EventArgs e)
{
     MyTextBox.Text = "Text to display";
}

You can either use autowireup to get the event handler wired to the button, or explicitly assign the event handler to the event in the Page_Load() method.

您可以使用autowireup将事件处理程序连接到按钮,或者在Page_Load()方法中将事件处理程序显式分配给事件。

The easiest way to assign the event to the button is to declare it in the .aspx code like this:

将事件分配给按钮的最简单方法是在.aspx代码中声明它,如下所示:

<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />

It will be done automatically if you doubleclick this button in the designer mode.

如果在设计器模式下双击此按钮,它将自动完成。

You can set the result in a button Click Handler like...

您可以在按钮中设置结果单击处理程序,如...

protected void Button1_Click(object sender, EventArgs e)
{
    TextBox1.Text = "Result Text.....";
}

There is a Text property of Textbox controls, that is used to Set/Get values.

Textbox控件有一个Text属性,用于设置/获取值。

 public void button_Click(object sender, CommandEventArgs e)
{

    txt.Text = "Testing";      
}

#4

lambdas anyone???

button.Click += (s, e) => { textbox.Text = "whoa!"; }

hmmm?

#5

public void button_Click(object sender,  EventArgs e)
{
    string str="String";
    int i=100;
    textbox1.Text = "string text";  
    //or
    textbox1.Text = str;  
   //or
    textbox1.Text = i.Tostring();
  //and same as above for other types i.e, convert to string when assigning to textBox because textbox takes value as string only
}

#6

protected void Button1_Click(object sender, EventArgs e)
{
     TextBox1.Text = "Text Message";
}
