ASP.NET中的TextBox焦点问题

我正在ASP.NET中开发一个简单的Web应用程序。

我的第一个TextBox设置为ReadOnly。



所以我想要专注于我的第二个TextBox即TextBox2。



我尝试使用以下代码。

I am developing a Simple Web Application in ASP.NET.
My First TextBox is set as ReadOnly.

So I want to focus on my second TextBox i.e. TextBox2.

I tried with the following codes.

protected void Page_Load(object sender, EventArgs e)
    {
        TextBox2.Focus();
    }

或

or

protected void Page_PreRender(object sender, EventArgs e)
    {
        TextBox2.Focus();
       
    }

或

or

protected void Page_Load(object sender, EventArgs e)
    {
        Page.SetFocus(TextBox2);
    }

protected void Page_PreRender(object sender, EventArgs e)
    {
        Page.SetFocus(TextBox2);
       
    }

但没有任何代码正常工作。

这些代码将光标置于TextBox2中。但是光标没有闪烁。

所以，在我用鼠标移动指针并在文本框中单击之前，我无法在文本框中书写。

我需要光标闪烁并且能够在页面加载时写入。



请建议！

but none of the code is working.
Cursor placed in TextBox2 by those code. but the cursor is not blinking.
So, I can''t write in the textbox until I use my mouse to move the pointer and click there in textbox.
I need the cursor to be blink and be able to write at the time of page load.

Please suggest!
