I suggest you to use Ajax AutoComplete (something like Google suggest) instead of using dropdown list.
eg:

Hi Michael,

I know there is a solution in Ajax. But if i select Ajax, then i will find difficult to implement in my project. So is there any solution without using Ajax.

Thanks and Regards,

AJAX is just javascript. The odds of there being a non js solution are close to zero.

Have you tested in Firefox (latest version)? It works well as the way you want without changing anything. but it doesn't work in IE6.

I'm looking for the solution for you.. I will let you know once done.

Hello Hariharan,

I just arrive at home and I remember your question that I don't have enough time to figure out the solution.. So, I opened my page and I'm trying to reproduce this issue. Now, I have tested with Internet Explorer 7, Firefox 2.0.0.6, Opera 9.2 and Safari 3.0.3. It is working fine in all those browsers except internet explorer 6. I don't have this one in my laptop. I tried to install IE6 standalone version that can run with IE7 on same machine but that installer doesn't work on Windows Vista. Frown | :(

Anyway, I'm gonna give you some codes that I think it should work on IE6.

<script language="javascript" type="text/javascript"><br />
      var pressedKeyString = "";<br />
      var delay = 1000;<br />
      var timeID = null;<br />
      function move(id){<br />
        <br />
        var selectList = document.getElementById(id);<br />
        var arr = new Array();<br />
        <br />
        var idx = 0;<br />
        <br />
        for(var i = 0; i < selectList.options.length-1; i++){           <br />
           if(selectList.options[i].value.length >= pressedKeyString.length){<br />
             if(pressedKeyString.toLowerCase() == selectList.options[i].value.substring(0,pressedKeyString.length).toLowerCase()){<br />
                 selectList.options[i].select = true;                                  <br />
                 i=selectList.options.length;                                  <br />
             }<br />
           }                      <br />
        }<br />
        <br />
        //pressedKeyString = "";<br />
      }<br />
      <br />
      function foo(e,id){<br />
        if(timeID != null)clearTimeout(timeID);<br />
        timeID = setTimeout("move('" + id + "');",delay);<br />
        <br />
        var key;<br />
        if(window.event) // IE<br />
        {<br />
           key = e.keyCode<br />
        }<br />
        else if(e.which) // Netscape/Firefox/Opera<br />
        {<br />
           key = e.which<br />
        }        <br />
        <br />
        var pressKey = String.fromCharCode(key);<br />
        pressedKeyString += pressKey;           <br />
        <br />
      }<br />
      <br />
    </script>

 protected void Page_Load(object sender, EventArgs e)<br />
    {<br />
        DropDownList1.Attributes.Add("onkeypress", "foo(event,'" + DropDownList1.ClientID + "');");<br />
<br />
        List<string> list = new List<string>();<br />
        list.Add("Alien");<br />
        list.Add("Emos");<br />
        list.Add("Poker");<br />
        list.Add("Peter");<br />
        list.Add("Michael Sync");<br />
        list.Add("Petro");<br />
        list.Add("Pet");<br />
        list.Add("Elizabeth");<br />
<br />
        DropDownList1.DataSource = list;<br />
        DropDownList1.DataBind();<br />
    }

The main idea of this code is that we will enable the timer to check whether the user is still typing or not. The timer will get clear as long as the user keep on typing. If the user stop then the timer will count 1000 minisecound and will invoke the Move function. In that function, we will do some string comparison to find whether there is any item which is started with the string that the user type or not. If we found the matched string then we will make this item as a selected item..

this is the idea. I'm not so sure whether it gonna work without error or not since I haven't tested yet and I don't have IE6 installed in my machine. For the time being, you can do some modifications to this code if you interest the idea. I will test my script for you tomorrow because the machine from my office has IE6 installed.

Anyway, what I like to suggest you is that if the particular thing works on main browsers except IE6, you should not spend so much time for finding the solution ...

Hi Michael,

I have checked your code, its not working in IE6. There is a small doubt, is there 'onkeypress' event for Dropdownlist.

Hello Hariharan,

Sorry for late reply. Yesterday was a holiday (Birthday of S'pore[^])

I have tested my code that I gave you earlier. There is only thing that we need to change in my code.

We should use selectedIndex selectList.selectedIndex = 2; instead of selectList.options[i].select = true;

The completed code is as below ~

<script language="javascript" type="text/javascript"><br />
      var pressedKeyString = "";<br />
      var delay = 1000;<br />
      var timeID = null;<br />
      function move(){<br />
        <br />
        var selectList = document.getElementById('DropDownList1');<br />
        var arr = new Array();<br />
        <br />
        var idx = 0;<br />
        <br />
        for(var i = 0; i < selectList.options.length-1; i++){           <br />
           if(selectList.options[i].value.length >= pressedKeyString.length){<br />
             if(pressedKeyString.toLowerCase() == selectList.options[i].value.substring(0,pressedKeyString.length).toLowerCase()){                              <br />
                 selectList.selectedIndex = i;<br />
                 i=selectList.options.length;                                  <br />
                 alert(pressedKeyString);<br />
             }<br />
           }                      <br />
        }<br />
        <br />
        pressedKeyString = "";<br />
      }<br />
      <br />
      function foo(e,id){<br />
        if(timeID != null)clearTimeout(timeID);<br />
        timeID = setTimeout("move();",delay);<br />
        <br />
        var key;<br />
        if(window.event) // IE<br />
        {<br />
           key = e.keyCode<br />
        }<br />
        else if(e.which) // Netscape/Firefox/Opera<br />
        {<br />
           key = e.which<br />
        }        <br />
        <br />
        var pressKey = String.fromCharCode(key);<br />
        pressedKeyString += pressKey;<br />
        <br />
        <br />
        <br />
      }<br />
    </script>

Note that "onkeypress" event is a javascript event (not server-side event).

As I mentioned my idea, the character that you typed will keep on appending to the string called pressedKeyString. (while you are typing, the select list will be changed by default. (this is what we don't want)). After finished typing (timer will count to 1000 minisecound), then the dropdown list will be changed to the option which is matched with the characters that you enter. (eg: if you type "pe" then dropdown list will select to "Peter".)

Hope it helps. Let me know whether it works for you or not..

Hi Michael,

Ya its working fine for me. Thanks a lot for your kind help. But again there is one small problem. When i type 'pe' it goes to 'Peter'. After that when i do it for the second time, its not working.(i.e After i typed 'pe', I wait for 1000 ms for the dropdownlist to select 'peter'. That's fine. Then I typed 'Ki', the dropdownlist has not select the name 'Kiran'. It selects "Indhu"). Have you checked that. If you know the answer let me know.
Else again thanks a lot for your kind help.

Thanks and Regards,

Did you wait for 1000 ms after typing 'Ki'?

I have tested with the following data..

DropDownList1.Attributes.Add("onkeypress", "foo(event,'" + DropDownList1.ClientID + "');");<br />
<br />
        List<string> list = new List<string>();<br />
        list.Add("Alien");<br />
        list.Add("Emos");<br />
        list.Add("Emos2");<br />
        list.Add("Poker");<br />
        list.Add("Peter");<br />
        list.Add("Michael Sync");<br />
        list.Add("Petro");<br />
        list.Add("Pet");<br />
        list.Add("Elizabeth");<br />
        list.Add("Kiran");<br />
        list.Add("Kate BackInSales");<br />
<br />
        DropDownList1.DataSource = list;<br />
        DropDownList1.DataBind()

I tried three times. ('Pe', 'Ki', 'Em'). It works fine.. Please try it again and let me know..

Note: you have to wait 1000 ms every time after typing something...

Hi Hariharan,

It's good to hear that. If my script works for you, don't forget to vote my message. Smile | :)

thanks.

Instead of using static name "DropDownList1", you should probably pass this name as the parameter. so, it will work if you have more than one dropdown.

var selectList = document.getElementById('DropDownList1');

This variable holds only one value. maybe. you can add more variables. or you can handle this variable to hold the value depend on what the user is typing.

var pressedKeyString = "";

Hope it helps.

Hi Michael,

In the function "foo(event,id)", can you tell me what is the use of the event.

See in my website I got this dropdown list in a formview insert template where it bound to the object data source. I have added your script to my master page. And the function calling is as follows,

protected void FormView1_DataBound(object sender, EventArgs e)
{
switch (FormView1.CurrentMode)
{
case FormViewMode.Insert:
((DropDownList)FormView1.FindControl("DropDownList3")).Attributes.Add ("onkeypress", "javascript:return foo(event,'ctl00_ContentPlaceHolder1_FormView1_DropDownList3');");
break;
}
}

But its not working in my page. So can you please help me on this. Dont worry Michael defenitely i am going to vote for you. Thanks in advance.

I think session_end is fired when a user's session times out.then i implemented it .the session time is 20 seconds.if the session times out , the control should automatically move to session_end function in global.asax file ? curently it is not moving to session_end function , as the session times out.
