View 2 RepliesI'm trying to add a JavaScript function to show all selected items from a ListBox as concatentated strings in a Label on the page. It's needed because AutoPostBack="true" will cause the ListBox to scroll all the way back to the first selected item.
So this code works:
<script type="text/javascript">
function Updatelist() {
var sel = document.getElementById('<%=lstbxStuff.ClientID%>');
var lbl = document.getElementById('ctl00_cph_lblSelectedStuff');
[Code]....
Unfortunately I still need the code behind SelectedIndexChanged delegate. Is there a way to use both of these without doing a PostBack? When I set AutoPostBack="false", my delegate never seems to be reached.
I'm using VS2008. When a dataset is bound to the DataSource of a ListView, SelectedIndexChanged event does not fire. If I used DataSourceID instead, it has no problem. But SelectedIndexChanging event fires for both.
why and how I can get SelectedIndexChanged event fired when DataSource is used?

View 6 RepliesI want to execute code written in a dropdown selectedindexchanged event from some another user defined function.
For this i m writing:
ddlMyDropDown1_SelectedIndexChanged(sender, e);
It works when use it in page_load (means the code in ddlMyDropDown1_SelectedIndexChanged is executed) but when i write the same line in another function it gives error "The name sender doesnot exists in current context".
i have a check box list control that is used for showing related files to some post.
what i want to do is set the databound items "checked" to true by default
then,
if a user unchecks some item and clicks the save button. then the selectedindexchanged will fire and i will do some logic.
what i have done is.
--Set All Databound items to "checked" --
[code]....
in the end i want the item that was unchecked to be removed (all other items will remain checked). but even before that, when the user control is loaded all the files that were bounded are being deleted by the index change event.
I ask for a date, on OnTextChanged event i bind data with a SqlDataSource to a dropdownlist and also bind data to a repeater passing the dropdownlist SelectedIndex (i use SqlDataSource too and ControlParameter to link the dropdownlist and the repeater) On my repeater during the ItemDataBound event i create dynamic dropdownlist controls, my code is :
[Code]....
[Code]....
On the Page_load event of my page i bind the data & recreate the control :
[Code]....
Everything works fine, datas are bound and SelectedIndexes are restore on every postback.
The probem occurs when user change different dropdownlists, if he choose to change the 1st dropdownlist the event is fire (normal), after if he modifies another dropdownlist the event is fire twice, if he modifies a 3rd time the event is fire 3 time etc...

i read article "using javascript with asp.net radiobuttonlist control" and i found it useful.
[var RB1 = document.getElementById("<%=RadioButtonList1.ClientID%>");
var radio = RB1.getElementsByTagName("input");
if am setting radio[1].checked = 1; the item is checked. ]
step1: radio[0]=checked
radio[1]=not checked
radio[2]=not checked
step 2: by using javascript , am changing the selection
now
radio[0]=not checked
radio[1]=checked
radio[2]=not checked
step 3: if am changing radio[0]=checked by clicking, it wont fire the selected index change that i wrote on code behind
but if am changing radio[2]=checked by clicking, it will fire the selected index change that i wrote on code behind
My requirement: i want to fire the selected index change in both cases. for that i need to change the selected index in step 2.
