I would like to fire off the server side selectedindexchanged method of a radgrid on doubleclick and not on click. Is it possible to do this???
[code]....
Is it possible to do this? To postback on doubleclick or is there an alternative?
I am using VS2010 and .NET4 for a web app. I have a script manager/update panel that has a couple of grids.
The client just leaves the page opens and views an updated grid every 30 seconds or so.
I want to refresh the grid by calling the server side method to load the grid, but not load the whol page using meta refresh or similar (too much screen flicker and unnecessary bandwith).
Is it possible to set some timer using javascript or something and call a specific server method to refresh controls?
I have a scenario where i have 4 asp buttons , on click of each button there are 4 labels inside 4 seperate divs where each displays seperate data.
Now if i click second button i need to display second label text inside 2nd div and hide all other divs.How can i achieve this ?
OnClientClick event of each button calls displayAlternate() which displays repective div and hides other.
displayAlternate('second'); return false; --> if i do this server side event is not fired ...
If I return true div second label is not getting displayed..
How can I achieve functionality where all divs expect 2nd is hidden and i get server side event also..
Below is code.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
</head><body>
<form id="form1" runat="server">
<script type="text/javascript">
function displayAlternate(id) {

I have a large application and I'm going to enabling short-cut key for it. I'd find 2 JQuery plug-ins (demo plug-in 1 - Demo plug-in 2) that do this for me. you can find both of them in this post in StackOverFlowMy application is a completed one and I'm goining to add some functionality to it so I don't want towrite code again.So as a short-cut is just catching a key combination, I'm wonder how can I call the server methods which a short-cut key should fire?
Update: here is the scenario. When User press CTRL+Del the GridView1_OnDeleteCommand so I have this
protected void grdDocumentRows_DeleteCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
try
{
DeleteRow(grdDocumentRows.DataKeys[e.Item.ItemIndex].ToString());

I have a hidden control and i am adding oninit event from code behind on hidden control,but why does server side hiddenfield not fire oninit event?
Code:
<input type="hidden" runat="server" id="hidden" name="hiddenColConfigure"/>
Code behind:
hidden.Attributes.Add("oninit", "initHiddenConfigure("this");
I have a DropDown which is bounded to an ObjectDataSource. On its data bound event, I am adding "--select--" value on the 0 index. I have a LinkButton on the page and on its client click, i am selecting different item on drop down (using JavaScript). Suppose there are 3 items like --select--, option1, option2 and option3 and now on link button's client click i selected option3, now if I select the default value "--select--", it does not fire the SelectedIndexChanged event. If I select any other value then it fires. Why does it not work for the default value?
[code]....
I have added the AutoPostBack = "true" attribute to the drop down list. It doesn't work.
<asp:DropDownList CssClass="dropDownList" ID="ddlBusinessUnit"
AutoPostBack="true" runat="server" Width="250px"
OnSelectedIndexChanged="ddlBusinessUnit_SelectedIndexChanged">
</asp:DropDownList>
code behind:
Protected Sub ddlBusinessUnit_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs)
Response.Write("Hello")
End
How can I ensure that the event method is called?
I'm being really thich today. Can anyone tell me why I can't fire a client side then server event from this code:

I recently came across the AsyncFileUpload control in the latest (3.0.40412) release of the ASP.Net Ajax Control Toolkit. There appears to be an issue when using it in a hidden control that is later revealed, such as a tag with
[Code]....
Server-side Code -
[Code]....
I have a breakpoint on the UploadedComplete event but it never fires. However, if you take the AsyncFileUpload control out of the , making it visible at initial page render, the control works as expected.
I have a DropDownList that fires off some server-side databinding in its OnSelectedIndexChanged event.
<asp:DropDownList ID="ddlGroup" runat="server"
AutoPostBack="True" OnSelectedIndexChanged="SelectGroup" />
Elsewhere in the page, some JavaScript opens a popup. When the popup is filled out and submitted, I want to use JavaScript to fire that OnSelectedIndexChanged event in the opener page. I found some other code that does something similar:
if (window.opener != null ) {
var cf = window.opener.document.forms['aspnetForm'];
if (!cf) {
cf = window.opener.document.aspnetForm;

I have a pop-up div contains a table.
I need to make table rows clickable and can be catched by both js and .net server side .
how can I use Request.form to solve this issue? since I've created functions for js part .
The reason why I want to fire sever side event, because I use JS to add option (item) to an asp:ddl in an updatepanel, it will cause error or lose the new option by doing a postback fired by other buttons.
I have some code which fires when user selects an item in dropdownlist. Now i want the same code to fire when i set selectedindex programmatically.
I have tried setting
ddlSystemLevelDCP.SelectedIndex=2;
and this as well
ddlSystemLevelDCP.SelectedValue="2";
None of them fires this event.However when user changes the selection,this event fires.Please tell me what am i missing.
I have a RadioButtonList with some fixed element and a default selected. If I uncheck the selection with javascript, on postback the SelectedIndexChanged event is not fired.
I would expect that the SelectedIndexChanged is called because the index is changed to -1.
this is the Asp.Net code
<asp:RadioButtonList ClientIDMode="Static" ID="RadioButtonList1" runat="server"
onselectedindexchanged="RadioButtonList1_SelectedIndexChanged">
<asp:ListItem Value="1" Selected="True"></asp:ListItem>
<asp:ListItem Value="2"></asp:ListItem>
</asp:RadioButtonList>
and the jquery code
$('#RadioButtonList1 :radio:visible').attr('checked', false);
As far as I know, the stage of data collection from the submit of the form is handled by IPostBackDataHandler.LoadPostData method.
I derived a class from RadioButtonList to verify when LoadPostData is called and I noticed that when non of the radio button is selected the method is not called and the same for SelectedIndexChanged event.
it seems that if the key of RadioButtonList is not present in the Page.Request.Form.Keys array, the LoadPostData is not called.

I have developed a web application which contains aspdotnet treeview control. In this treeview control has binded with some database value.. that controls has one parent node and more than one child nodes for each parent node.
my problem is here, when the user clicks the parent node, I need to fire a javascript onclick function before the server side event(SelectedNodeChanged) called..
If I provide javascript to the parnet node when it is binding, then I could not fire the server side event(SelectedNodeChanged).
How to provide onclick javascript event for parent node in treeview control even the parent node has SelectedNodeChanged event.
I have seen a million forums ask this question. This is what has been working for me.
protected void checkboxlist_SelectedIndexChanged(object sender, EventArgs e)
{
CheckBoxList list = (CheckBoxList)sender;
string[] control = Request.Form.Get("__EVENTTARGET").Split('$');
int idx = control.Length - 1;
string sel = list.Items[Int32.Parse(control[idx])].Value;
I'm way off and have just been lucking out, but I haven't seen a case where the index wasn't the last value in a '$' terminated string.
I just wanted to clarify if selectedIndexChanged works on ajax cascading dropdowns as mine doesn't fire. Its in a user control inside an accordion pane. I've read conflicting things about this. All I want to do is check that the last of the 3 cascading dropdowns has been populated an enable a button if so.... but the event never fires when i make a selection on the last dropdown. If it isn't suppose to fire is there a way to raise an event when the selection is made and unmade (as when you change one of the other dropdowns the value resets and the buttton needs to be disabled.
View 3 RepliesI've got a UserControl that's used inside of an UpdatePanel. The UserControl is a fairly simple form that appears via a ModalPopupExtender (which is also part of the UserControl). There are four DropDownLists, as well as some other UI elements. Three of the four DropDownLists have AutoPostBack="true", with SelectedIndexChanged events that fire on the server and cause some of the other DropDownLists to rebind. Two of the three DDL's that AutoPostBack are working fine. One of them, which I only just added, is showing some strange behavior. Let's say I bind five Items to it: 1, 2, 3, 4, 5. I set the SelectedIndex to 0, which makes 1 the selected item. If I select 5 and then 1 and keep toggling back and forth, everything works fine. The postback occurs and SelectedIndexChanged fires. Every time. If I ever select 2 or 4, the postback occurs but SelectedIndexChanged does not fire. Every time.
If I ever select 3, something bizarre happens and sometimes the value of the DDL reverts to 1. Even though breakpoints seem to show that it's not rebinding and no unexpected code is running. I know your first instinct will probably be that I'm wrong about the rebinding code not running, but I have literally been staring at the debugger for hours trying to find my mistake. Lots of breakpoints. I don't get it -- this really isn't that complicated. But obviously I am missing something. I've put about four hours into this so far and I think I'm just grinding at this point. I could use another perspective.

View 1 RepliesI am putting together a module that will drop into a DotNetNuke portal and I'm populating a Telerik RadGrid with data. I have followed every tutorial and example I can find, but the result keeps coming back with "object Object", "null", or "undefined".
I need to:
1) get the value of the "BookingID'" column for each row that is selected
2) pass the value into a url string that opens up in a RadWindow.
I'm trying to do all of this using javascript, but if you know a better way, I'm down for anything at this point.
Here is my current JavaScript and a stripped down radGrid:

I'm trying to display a confirm message box before firing selectedIndexChanged when user change selection in the dropDownList. I was wondering if anyone would an example of how to do this.
View 14 Repliesi 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.
