[英]asp.net textbox focus problems
I am trying to set focus on textbox on page load in asp.net as follows 我正在尝试将重点放在asp.net中页面加载的文本框上,如下所示
protected void Page_Load(object sender, EventArgs e)
{
try
{
if (!IsPostBack)
{
// fillUnitType();
//
fillLastCode();
txt_Grn_Date.Text = System.DateTime.Now.ToString("dd-MM-yyyy");
setinitialrow_lvl();
txt_Po_No.Focus();
}
}
catch (Exception ex)
{
lblMessage.Text = ex.Message;
}
}
But the textbox is not getting focused. 但是文本框并没有得到关注。 What is that I am missing.
我想念的是什么。 I have used update panel is it because of that.?
因为这个原因,我使用过更新面板吗? Or my css is slightly faulty.
或我的CSS有点错误。
try this in javascript 试试这个在JavaScript
<script language=javascript>
function fnLoad(){
document.getElementById("<%= txt_Po_No.ClientID %>").focus();
}
</script>
call " fnLoad
()" function on " onLoad
" event of body.. 在正文的“
onLoad
”事件上调用“ fnLoad
()”函数。
You need to add this function in body tag : Like 您需要在body标签中添加此功能:
<body onload="fnLoad()">........</body>
Update: 更新:
try another way 尝试另一种方式
<script language=javascript>
$(document).ready(function(){ document.getElementById("<%= txt_Po_No.ClientID %>").focus();})
</script>
or 要么
<script language=javascript>
$(window).load(function(){ document.getElementById("<%= txt_Po_No.ClientID %>").focus();})
</script>
Write following function in your codebehind and for every control call this function 在您的代码后面编写以下函数,并为每个控件调用此函数
private void Set_Focus(string controlname)
{
string strScript;
strScript = "<script language=javascript> document.all('" + controlname + "').focus() </script>";
RegisterStartupScript("focus", strScript);
}
Set 组
tapindex = 0
TextBox1.Focus();
or 要么
textBox1.Select();
or 要么
protected override void OnShown(EventArgs e)
{
textBox1.Focus();
base.OnShown(e);
}
or 要么
setTimeout("myFocusFunction()", 500);
function myFocusFunction(){
$("#myTextBoxID").focus();
}
I have tried this with updatepanel and textbox inside it. 我已经尝试过使用它里面的updatepanel和textbox了。
CodeBehind 代码背后
.aspx .aspx
output 输出
Try this code.. 试试这个代码。
string jsCode= "<script language=javascript>document.getElementById('<%= TEXTBOX.ClientID%>').focus();</script>";
ClientScript.RegisterClientScriptBlock(GetType(), "txtbox",jsCode, false);
