Web Forms :: How To Activate Javascript Function From Page_Load And Updatepanel
Feb 13, 2011
In the first Page_Load, I am activating a javascript function to make an ImageButton change between 2 images with an interval.
This works fine.
Now when pressing this imagebutton, the Page_Load event will fire the second time and all this is happening in an updatepanel which means a partial postback.
The question is how to execute the javascript function stopbk() in the Page_Load event in this scenario as I cant just put it in the "Onload". How can I make that work?
Code is below:

I am using a Timer with a 3 minutes interval. I am exeuting the Page_Load event every 3 minutes. I am doing that this way as I have all this code inside an UpdatePanel1 which causes
a partial unnoticed postback to the server. I have a lot of code in the Page_Load event that I haven´t put here.
But what does not work is the code I have in the Page_Load event now.
I am trying to execute the javascript function with this line: body1.Attributes.Add("Onload", "startbk()");
This function should start an imageButton to change image between 2 images. This function do works if I refresh the page so the function itself do works.
But it seems this function does not execute when the Timer executes the Page_Load event, so this is my problem how I can solve this?

I have a asp.net listbox server control that is connected to a jquery plugin that can handle a client side click event for each of the checkboxes it renders.
Whenever I click on a checkbox the click event gets triggered and I make a call to
__doPostBack("UpdatePanel1", ""); so that i can update the updatepanel and rebind the checkboxlist inside it.
is it possible to do the rebind first, and then update the updatepanel? how do i do that? because now, the rebind happens on the second time i click on the checkbox.

[URL] .... am using this functionality in my project and it is working very fine but i am facing very strange issue while using this.
The above functionality is not working when we place dropdownlist and textbox inside updatePanel and ModalPopupExtender
The .aspx page where i am using ModalpopupExtender and UpdatePanel for DropDownList and Textbox is below
<%-- *************************** MODAL POPUP EXTENDER ***************************************************** --%>
<asp:HiddenField ID="HiddenField3" runat="server" />
<asp:HiddenField ID="HiddenField4" runat="server" />
<cc1:ModalPopupExtender ID="ModalPopupExtender1" runat="server" PopupControlID="Div6" TargetControlID="HiddenField3"
BackgroundCssClass="modalBackground" CancelControlID="bclosemodalpopup" >
</cc1:ModalPopupExtender>
[Code] ....
The above code is not working with UpdatePanel but it is working if we remove DropdownList and Textbox from updatepanel.
The javascript code which i am using is below
<script type = "text/javascript">
var ddlText, ddlValue, ddl, lblMesg;
function CacheItems() {
ddlText = new Array();

I'm using a .js file to bind events to controls. I'm also using UpdatePanel to do async postbacks; however, when they postback,the controls lose the events that were initially bound to them. Is it possible to rebind the events in the Page_Load function by using the .js file?

I've tried to wrap up my problem with a complete example below - the original problem is part of a jQuery plug-in that I'm writing to extend the behaviour of an ASP.NET ajax application I already have.
The aspx page below has one drop down list which is marked for auto post back. I've also bound a change event using jquery (which ultimately I will swap for a .live() event to maintain the binding after the update panel refresh.) The problem is, when the jQuery event is bound I see two ajax begin requests and page_loads fire but only one ddlTest_OnselectedIndexChanged event. One of the page loads is malformed too - the content-length states it's about 300 bytes long whilst the totalBytes is 0 and form data empty. This does not happen if I bind to the click event of a button.
why the erroneous page_load event is firing ?

I have the following call in my master page
[Code]....
So, in the above on the Master Page onload I am calling the javascript to get the screen resolution Then in my default page....which is being used first. My master page is loading and then my default page is loading. I have this is my Page Load event
[Code]....
However, what is happening is that I am getting the MessageBox.Show from the default page saying the screen is <null> by <null> and then I start getting the alert boxes from the javascript saying what the screen width and screen height is. In my page Load event of default. how can I wait until the java script in Master is done? Or is the a better place to put these events?

I have noticed that window.onunload event fires off AFTER page_load event which makes no sense.
This behaviour is creating an issue for me - in my unonload I clear the session, so if the Page_Load first BEFORE onunload, there are errors on the page displayed.
I would expect the javascript onunload to fire BEFORE Page_Load....is that the correct assumption?
TO CLARIFY: Let's assume I am on page test.aspx, then I click on the link that goes to the same page (say I click on a menu), what I observe is that Page_Load fires first, then onunload fires off.
Makes no sense at all.

I am reimplementing an ASP.NET application with a main page (Call it "MyMainPage") which contains a user control. (Call it "MyNavControl") Within that user control is a menu control provided by a third party. Items added to this third party control have an "Href" property that is passed a URL. The code to create a menu subitem, contained within the codebehind of the .ascx for MyNavControl, goes something like this:
ThirdParty.MenuItem subitem = new ThirdParty.MenuItem();
subitem.Href="MyMainPage.aspx?_page=PremiumCustomer&_title=Premium";
MyMainPage also contains a user control representing the bulk of the page body. Let's call that MainBodyControl.ascx. The Page_Load() for the main page sets up some session values which are used in the Page_Load() for MainBodyControl.When the menu item on the main page is clicked, the main page's Page_Load() will be passed the arguments specified in the menu item control's "Href" value. So:
protected void Page_Load(object sender, System.EventArgs e)
{
string sPageType = "";[code]....
Here's my question: I'm replacing the third party controls with standard ASP.NET controls, so the current "Href" property mechanism can no longer be used. What would be the best way, in some JavaScript assigned to a menu item's click event, to set a new value for "_page" or "_title" above.

I am trying to replace the JavaScript onclick event handler in ASP.NET that is added to a button control when using validation controls. This is what is output into the HTML from ASP.NET in this scenario:
<input type="image" name="ibSubmit1" id="ibSubmit1" src="button-green-submit.gif" onclick="showProgress1();WebForm_DoPostBackWithOptions(new WebForm_PostBackOptions("ibSubmit1", "", true, "Group1", "", false, false))" style="border-width:0px;" />
I have looked pretty estensively, and unfortunately there doesn't seem to be a way to modify the function server side before it is injected into the page.
Since I am developing a control and desire it to be non-invasive and self contained, and I am interested in obtaining the validationGroup parameter of the WebForm_PostBackOptions object, it seems that the easiest solution would be to use JavaScript to replace the WebForm_DoPostBackWithOptions function name with my custom wrapper function and leave all of the rest of the parameter information intact - then I can extract the information I am interested in, call my custom functions, and then forward the call on to WebForm_DoPostBackWithOptions.
NOTE: I am using jQuery to build my custom function, so if there is an easier way to do this with jQuery it is an option I will consider.
Here is the code I tried to replace the onclick event handler (not working):
$('[onclick*=WebForm_DoPostBackWithOptions]').each(function() {
var txt = this.onclick;
txt = txt + '';
txt = txt.replace('WebForm_DoPostBackWithOptions','ml_DoPostBackWithOptions');
this.onclick = eval(txt);
});
Using alert(), I verified that the text is being changed correctly, however whether or not I use the eval() function, the onclick handler doesn't seem to recognize it as JavaScript.
I thought of using a regular expression to get the validationGroup value, but this seems like it will be far more elegant and flexible if I can get it working...
Note: If there is a way for my control to interrogate the page it is on to find all of the buttons that will post back (regardless of what type of buttons they are) so I can retrieve the property server-side, this is also something I will consider.

I have the function put here like below:
$(document).ready(function () {
UserControlNameInit();
});
The script are put in the following and the block is in the .ascx page.
<script type="text/javascript">
</script>
However, the function UserControlNameInit() does not run when the page loads. It is showing in the page source. I can still call this function through FireBug console by manually typing the name of the function.
I did the same way with other user controls, and it works. Just 1-3 user controls are not working...

I have a CustomValidator that validates a control within a web control. The web control is used in a template page that inherits from a master page.
The function is:
[Code]....
I also have this in the code behind of my web control:
ScriptManager.RegisterStartupScript(this, this.GetType(), "script3", "ValidatorHookupControlID('<%= txtGroup.ClientID %>', $('<%= valGroup.ClientID %>'));", true);
Now, the situation is
If I put ValidateGroupComplaint in a standalone js file (linked from the master page), then the alert line will always display nothing and always return false.
If I put ValidateGroupComplaint in a script block inside my web control, then it will work IF the web control is not in a UpdatePanel. If it is inside a UpdatePanel then it simply can't find the validator function (JS Error: object expected).
