Suggested change should be done in OnClientClick Event

<asp:Button ID="Button1" runat="server" Text="Button" 
OnClientClick='checkValue2(forms[0].TextBox1)' />

I have placed it in my code as following

<head runat="server">
    <title>Untitled Page</title>
    <script type="text/javascript" runat="server">
      var TextID="<%TextBox1.ClientID")";
        function checkValue2()
        {   
            Var ClientTextID= document.getElementByID(TextID);
            if(ClientTextID.value='')     
            {     
                alert('text box is null);     
            } 
            else    
            {    
                alert('text box is not null);   
            }
        }
</script>
</head>

But it seems to be wrong?

The only problem that I see in your code is runat="server" in the script block.

If you specify a script block as runat="server" it will take it as C# / VB.NET block based on the language.

So remove the runat = server and also use
OnClientClick to define javascript block.

use this :

<asp:Button ID="Button1" runat="server" Text="Button"  OnClientClick="javascript:checkValue2(this)" /> 

<script type="text/javascript" >
function checkValue2( obj)
{
    if (obj.value == "")
        alert ("empty");
    else
        alert ("not empty");
}
</script>

this will work. Wink | ;)

do not use expression in CSS...

Browser renders it for every action, thus the site will be slower. Even mouse-move will call it also. Smile | :)

do you check for document.selection.createRange for IE ?

Use like this :

var txt = '';
if (window.getSelection) //FF
   txt = window.getSelection();
else if (document.getSelection)
   txt = document.getSelection();
else if (document.selection) // IE
   txt = document.selection.createRange().text;

I think this will do the trick. Wink | ;)

hi ,
i used it , its not working .
i.e it is triggered if the cursor is just the textbox .

actually we want to enable the input only if the text is selected . i.e it is one condition.

and even return true; is not working in FF.

so is there any other way we could do it .

You need to focus before you call selection.
Use this function :

function ShowSelection()
{
  var textComponent = document.getElementById('Editor');
  var selectedText;
  // IE version
  if (document.selection)
  {
    textComponent.focus();
    var sel = document.selection.createRange();
    selectedText = sel.text;
  }
  // Mozilla version
  else if (textComponent.selectionStart)
  {
    var startPos = textComponent.selectionStart;
    var endPos = textComponent.selectionEnd;
    selectedText = textComponent.value.substring(startPos, endPos)
  }
  alert("You selected: " + selectedText);
}

I think this will solve the problem. Rose | [Rose]

Hi ,
sorry for late reply.
but i got the solution to find if the text is selected in a textbox.
@abhishekh the by u was helpful to for the solution.

it is something like,

i.e

//first need to find the start index and end index (Firefox)
     var s1= srcElement.selectionStart; 
     var s2= srcElement.selectionEnd;

//IE code ( i.e if IE)
if( document.selection )
{
if(document.selection.type == 'Text') // to find if text is selected
{
statements .....
}

//firefox code 
else
{
if ( s1 != s2)                        // to find if text is selected
{
statements....
}
}

which is very simple.

Thanks and Regards,
sriharsha

Classic ASP ConnectionString?

Hi Guys,

I know that this is an ASP.Net forum, but just in case some of you still remember about the classic ASP, I have one question.

How can I assigned connection in Classic ASP using the MSSQLServer 2005?

I tried this code below, but I got an error.

Below is the connection string I have tried, but has an error

Application("ConnStr") = "server=PC\SQLEXPRESS;database=TestDB;Trusted_Connection=True;"

What's wrong with it?
