在回发后设置焦点在html控件上 [英] set focus on the an html control after postback

问题描述

我在ASP.NET中使用表单，其中下拉列表会导致回发。 **我希望在回发发生后将焦点设置回特定的文本框控件。**





我试过调用



SetFocus（TextBox1.ID）





但我的重点不变。我在Page_Load中调用了这个函数。我在调试模式下运行应用程序并验证TextBox1不是null并且引用了正确的文本框。



顺便说一下TextBox1是一个html控件。这是标记



< input type =textid =TextBox1runat =server/>





这是导致回发的下拉列表





< asp： DropDownList ID =dropdown_finance runat =server

OnSelectedIndexChanged =dropdown_financer_SelectedIndexChanged

AutoPostBack =true>



< asp：ListItem Selected =True>父亲/丈夫

< asp：ListItem>母亲

< asp：ListItem>指定信息财务人员





我只想把焦点设置到我的文本框。怎么做？

I am using a form in ASP.NET where dropdownlists cause postback. **I want to set focus back to a specific textbox control after postback occurs.**


I tried calling

SetFocus(TextBox1.ID)


but my focus is not changing. I called this function in Page_Load. I ran the app in debug mode and verified that TextBox1 is not null and refers to the correct textbox.

By the way TextBox1 is an html control. Here is the markup

<input type="text" id="TextBox1" runat="server" />


Here is the dropdownlist that causes postback


<asp:DropDownList ID="dropdown_finance runat="server"
OnSelectedIndexChanged="dropdown_financer_SelectedIndexChanged"
AutoPostBack="true">

<asp:ListItem Selected="True">Father / Husband
<asp:ListItem>Mother
<asp:ListItem>Specify information of financer


I just want to set focus to my textbox. How to do this?
