推荐答案

您需要使用Js onFocus Event.

假设有三个名为的文本框，

TextBox1,TextBox2,TextBox3

然后在TextBox3 Like上编写onFocus事件.

You need to use Js onFocus Event.

Suppose there are three textbox named,

TextBox1,TextBox2,TextBox3

Then write onFocus Event on TextBox3 Like.

<asp:textbox id="TextBox3" runat="Server" onfocus="javascript:focused(this)" xmlns:asp="#unknown" />

function focused(txt3)
{
var result = document.getElementById("TextBox1").value * document.getElementById("TextBox2").value;
            txt3.value = result;

}

使用输入文本框的事件..

使用以下代码

use the enter event of the textbox ..

use the below code

<pre lang="cs">private void textBox3_Enter(object sender, EventArgs e)
       {
           textBox3.Text = Convert.ToString (Convert.ToInt32(textBox1.Text) + Convert.ToInt32(textBox2.Text));
       }

在模糊的情况下进行操作，就像拖动按钮并在按钮上单击以编写您的代码:


textBox3.Text = Convert.ToString(Convert.ToInt32(textBox1.Text)+ Convert.ToInt32(textBox2.Text));

和
页面的onload事件写这个

受保护的void Page_Load(对象发送者，EventArgs e)
{
Button1.Visible = false;
字符串处理程序= ClientScript.GetPostBackEventReference(this.Button1，");
TextBox2.Attributes.Add("onblur"，处理程序);
}

do it on blur like it drag a button and on button click write ur code:


textBox3.Text = Convert.ToString (Convert.ToInt32(textBox1.Text) + Convert.ToInt32(textBox2.Text));

and
onload event of page write this

protected void Page_Load(object sender, EventArgs e)
{
Button1.Visible = false;
string handler = ClientScript.GetPostBackEventReference(this.Button1, "");
TextBox2.Attributes.Add("onblur", handler);
}
