****ASP.NET VB.NET 2010 *********

Hi,

Kindly help me with this, I have a list of Hyperlink. If I press radio button I want my cursor to focus on one of my hyperlink

I tried to used this but no luck

Dim sScript As String = "<SCRIPT language='javascript'>document.getElementById('" & hlnkQNo.ID & "').focus();</script>"
'Page.RegisterStartupScript("controlFocus", sScript)

我也尝试了此操作，但同样，光标没有集中在我的链接ScriptManager1.SetFocus(hlnkQNo.ID)上.
这是我想要的例子
超链接1
超链接2
超链接3
超链接3
超链接4

如果使用单击单选按钮，我想关注Hyperlink4

-请注意，所有控件都是动态创建的(在运行期间)
-请注意，所有控件都是动态创建的(在运行时)

I also tried this but the same, the cursor was not focus on my link ScriptManager1.SetFocus(hlnkQNo.ID).

Here is my example of what I want
Hyperlink1
Hyperlink2
Hyperlink3
Hyperlink3
Hyperlink4

if the use click the radio button i want to focus on Hyperlink4

--KINDLY NOTE THAT ALL CONTROLS ARE CREATED DYNAMICALLY (DURING RUNTIME)
-- Kindly note that all the controls are created dynamically (during runtime)

推荐答案

Hi.

可能hlnkQNo.ID只是服务器端ID，不能在javascript中使用.您可以使用hlnkQNo.ClientID从JS查找html元素.

玩得开心！

Hi.

Probably hlnkQNo.ID is only server side ID and it cannot be used in javascript. You can use hlnkQNo.ClientID to find your html element from JS.

Have fun!

private void radioButton1_CheckedChanged(object sender, EventArgs e)
{
    hlnkQNo.Focus();
}

1.为单选按钮添加一个事件.
2.在此事件内为控件设置Focus.

1. Add an event for the radio button.
2. Set the Focus for the control inside this event.
