I have two fields, text area and Listbox. When i select each item in listbox it has to display in text area with appending on the text in it. and if i move the cursor before some text and select another item from listbox it must append the item where the cursor is placed.
i am fresher to this field so please help how do i do it??

i tried with this txtTemplatebody.Text = txtTemplatebody.Text + lbTokenList.SelectedItem.ToString(); but when i tried to append on front it's not working.

Thanks in advance

Is the problem in C# or JavaScript?

C#

function insert(el, ins) {
    if (el.setSelectionRange) {
        el.value = el.value.substring(0, el.selectionStart) + ins + el.value.substring(el.selectionStart, el.selectionEnd) + el.value.substring(el.selectionEnd, el.value.length);
    }
    else if (document.selection && document.selection.createRange) {
        el.focus();
        var range = document.selection.createRange();
        range.text = ins + range.text;
    }
}

function Updatelist() {

    var sel = document.getElementById(listboxID);
    var listLength = sel.options.length;
    for (var i = 0; i < listLength; i++) {
        if (sel.options[i].selected) {
            return sel.options[i].value;
        }
    }
}

Finally add
listboxid.Attributes.Add("Onclick", "insert(" + txtid.ClientID + ",Updatelist())"); in .cs page
