VB.Net - Focus - .NET Framework

krndhi1983

Hi to all
I am facing this kind of problem.

When i write the following code

TextBox1.Focus()

If the text box already contains any values the cursor will be placed below the first character of the string of textbox.I need to place the cursor at the end of the string in the textbox.
Any one can response me?

Sorry for the bad English.

This is going to require a lot of JavaScript.
Please see this thread on text box cursor location...I think it may help you.

This may also help you understand how to use JavaScript in .NET

The others have already started answering this question, but I am wondering, is this a web application? or a desktop application?

I found this on an msdn forums when looking for javascript selection

Expand|Select|Wrap|Line Numbers

 
<HTML>

<HEAD>

<TITLE> Select Test </TITLE>

</HEAD>

<SCRIPT LANGUAGE="JavaScript">

<!--

function selectSomeText(element){         

  var workRange=document.selection.createRange();     

  var allRange=element.createTextRange();     

  workRange.setEndPoint("StartToStart",allRange);     

  workRange.select();

}

function getCaretPosition(element){

                var workRange=document.selection.createRange();     

                var allRange=element.createTextRange();     

                workRange.setEndPoint("StartToStart",allRange);

                return workRange.text.length;

}

//-->

</SCRIPT>

<BODY>

<form method="GET" name="Login">

<pre>

<input type="type" value ="This is the user name" onclick="selectSomeText(this)" style="width:300px"><br>

<input type="type" value ="abcdefghijklmnopqrstuvw" onclick="alert(getCaretPosition(this))" style="width:300px">

</pre>

</form>

</BODY>

</HTML>

You should be able to pull what you need from out of that

That could have been very useful when I was trying to implement this!
Of course I always have to do things the hard way first.
I guess that's just how I learn :)

Thanks Plater!

I just made it better

Expand|Select|Wrap|Line Numbers

 
function MoveToEnd(element)

{

    var ee=element;

    var eelen =(ee.value.length);

    setCaretTo(ee,eelen);

}

function setCaretTo(obj, pos) 

{

    if(obj.createTextRange) 

    {

        var range = obj.createTextRange();

        range.move('character', pos);

        range.select();

    } 

    else if(obj.selectionStart) 

    {

        obj.focus();

        obj.setSelectionRange(pos, pos);

    }

}

Use whatever means you want to get the textbox element (I used .getElementById() to pass in to movetoend)
