Hi Michael, Yes its working fine in firefox. But its there any other way to make it work in IE. If you got the solution let me know it. Thanks and Regards, Hariharan C
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. :( Anyway, I'm gonna give you some codes that I think it should work on IE6.
var pressedKeyString = ""; var delay = 1000; var timeID = null; function move(id){ var selectList = document.getElementById(id); var arr = new Array(); var idx = 0; for(var i = 0; i < selectList.options.length-1; i++){ if(selectList.options[i].value.length >= pressedKeyString.length){ if(pressedKeyString.toLowerCase() == selectList.options[i].value.substring(0,pressedKeyString.length).toLowerCase()){ selectList.options[i].select = true; i=selectList.options.length; } } } //pressedKeyString = ""; } function foo(e,id){ if(timeID != null)clearTimeout(timeID); timeID = setTimeout("move('" + id + "');",delay); var key; if(window.event) // IE { key = e.keyCode } else if(e.which) // Netscape/Firefox/Opera { key = e.which } var pressKey = String.fromCharCode(key); pressedKeyString += pressKey; }protected void Page_Load(object sender, EventArgs e) { DropDownList1.Attributes.Add("onkeypress", "foo(event,'" + DropDownList1.ClientID + "');"); List list = new List(); list.Add("Alien"); list.Add("Emos"); list.Add("Poker"); list.Add("Peter"); list.Add("Michael Sync"); list.Add("Petro"); list.Add("Pet"); list.Add("Elizabeth"); DropDownList1.DataSource = list; DropDownList1.DataBind(); }The main -

Hi Michael, Have you got the solution for me. I am not able to get it. So if you got the solution let me know please. Thanks and Regards, Hariharan C
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 ofselectList.options[i].select = true;The completed code is as below ~var pressedKeyString = ""; var delay = 1000; var timeID = null; function move(){ var selectList = document.getElementById('DropDownList1'); var arr = new Array(); var idx = 0; for(var i = 0; i < selectList.options.length-1; i++){ if(selectList.options[i].value.length >= pressedKeyString.length){ if(pressedKeyString.toLowerCase() == selectList.options[i].value.substring(0,pressedKeyString.length).toLowerCase()){ <b> selectList.selectedIndex = i;</b> i=selectList.options.length; alert(pressedKeyString); } } } pressedKeyString = ""; } function foo(e,id){ if(timeID != null)clearTimeout(timeID); timeID = setTimeout("move();",delay); var key; if(window.event) // IE { key = e.keyCode } else if(e.which) // Netscape/Firefox/Opera { key = e.which } var pressKey = String.fromCharCode(key); pressedKeyString += pressKey; }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 dropd -

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.

Did you wait for 1000 ms after typing 'Ki'? I have tested with the following data..
DropDownList1.Attributes.Add("onkeypress", "foo(event,'" + DropDownList1.ClientID + "');"); List list = new List(); list.Add("Alien"); list.Add("Emos"); list.Add("Emos2"); list.Add("Poker"); list.Add("Peter"); list.Add("Michael Sync"); list.Add("Petro"); list.Add("Pet"); list.Add("Elizabeth"); list.Add("Kiran"); list.Add("Kate BackInSales"); DropDownList1.DataSource = list; 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...Thanks and Regards, Michael Sync ( Blog: http://michaelsync.net) If you want to thank me for my help, please vote my message by clicking one of numbers beside "Rate this message".

Hi Michael, I checked it again. For me its working fine for the first time only. Anyway Michael thanks a lot for your help. Thanks and Regards, Hariharan C
Hi Hariharan, I think that you didn't check the code that I give you second time. I have uncommented the

Hi Michael, Now I have added one more dropdownlist and bound to the object data source(says Employee name). Then I tried to call your script, where its not working. Can you please tell me what I have to do now. Thanks and Regards, Hariharan C
Hi Hariharan, It's good to hear that. If my script works for you, don't forget to vote my message. :) 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.Thanks and Regards, Michael Sync ( Blog: http://michaelsync.net) If you want to thank me for my help, please vote my message by clicking one of numbers beside "Rate this message".

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. Thanks and Regards, Hariharan C
