How can I set TextBox value from asp.net Listbox, because I popuplate asp.net Listbox through java script.. I tried it by calling the java script function onChange(and onSelectedIndexChange) event of list box, but event is not calling java script function from here.. following is my code--

onChange="setTextBoxValue(this.value);">

function setTextBoxValue(e) { //var strListBoxName = document.getElementById('lstShowHistory'); document.getElementById('txtUrlLink').value = e ; //strListBoxName.options[strListBoxName.selectedIndex].text ; //;options[document.getElementById('lstShowHistory').selectedIndex].text; } the list box is popuplate on mouse over event on the text box... txtUrlLink.Attributes.Add("onfocus", "ShowList();"); function ShowList() { getCookie(); document.getElementById('helptypediv').style.visibility='visible';return false; } function getCookie() { if(document.cookie) { var strListBox = document.getElementById('lstShowHistory'); var ls1= document.cookie.split("="); if (ls1.length >1) { var ls2 = ls1[1].split("|"); var count = ls2.length; var strLink = ""; var optionItem; //Clear the previous options from the list for(var lstCount = strListBox.options.length-1; lstCount>-1; lstCount--) { strListBox.options[lstCount] = null; } if(count >= 2 ) { for(var x = count-1; x>=0; x--) { var ls3=ls2[x];//[x].split("|"); strLink+= ls3; optionItem = new Option(ls3, ls3, false, false); strListBox.options[strListBox.length] = optionItem; } } } } }

You didn't ask in the ASP.NET forum because.....

onChange

It's all lowercase, I believe. onchange.

Your big issue will be that the names you give ASP.ENT controls on the server, are not the names they have on the client. Use the ClientID property to find the client side name, and pass that to the client so getElementById will work

Thanks sir for guidance, I have resolved my problem following is code.. in CS file i added this line .. lstShowHistory.Attributes.Add("onchange", "ShowText();"); and by javascript I set the value of textbox, but it works only on by selecting item from mouse. How can I select value from the listbox by arrow key of keyboard?? Have you any idea... function ShowText() { var txtMessage = document.getElementById('lstShowHistory').options[document.getElementById('lstShowHistory').selectedIndex].text;//GetComboText(document.getElementById('lstShowHistory')); document.getElementById('txtUrlLink').value = txtMessage; document.getElementById('helptypediv').style.visibility='hidden';return false; }
