Set Focus at end of text in textbox

Hey, Is it possible with easy options in ASP.NET to se开发者_如何学JAVAt the focus at end of text in a textbox-element ? Without JavaScript ?

ASP.NET textboxes render as standard HTML inputs (with type="text") and the only way to achieve what you are asking is through javascript:

var textbox = document.getElementById('foo');
textbox.focus();
textbox.value = textbox.value;

where foo is the id of the generated input:

<input type="text" id="foo" name="foo" value="some text" />

you can use this in serve-side:

ScriptManager.RegisterStartupScript(this, this.GetType(), "tmp2", "var t2 =     document.getElementById('foo'); t2.focus();t2.value = t2.value;", true);

Solution using jquery

$('#loginBtn').on('click',function(){
   var val = $('#txtLoginName').val();
   $('#txtLoginName').val('');
   $('#txtLoginName').val(val);
   $('#txtLoginName').focus();
});

html code

<input type="text" id="txtLoginName" value="test"/>

Fiddle Example

This even works for update panel, i believe all other situations too

ScriptManager.RegisterStartupScript(this, this.GetType(), "tmp2", "$('#ContentPlaceHolder1_TxtSupplier').focus();var value = $('#ContentPlaceHolder1_TxtSupplier').val();$('#ContentPlaceHolder1_TxtSupplier').val('');$('#ContentPlaceHolder1_TxtSupplier').val(value);", true);
