Using this script on a button click
[Code]....
After it is done, I can't click on my calendar control. I was hoping to add somethign that would force a refresh in the script, but nothing I do works.
iam using the Jquery Uframe with asp.net project.Iam getting a postback problem here.
In side the uframe ,button control getting postback the page even the client side method call also.
i tried with the Html button Control also by setting the type="submit" ,iam facing the same problem.
And I got very limited reference about the uframe(codeflex,codeProject).
I have a web application that shows a page containing between 6 and 20 AJAX UpdatePanels, contained with Custom Web (.ascx) Controls.
You can see an example of such a page here:
[URL]
The problem I'm getting is that when the user FIRST clicks any of the radio-buttons on any of the controls in the page, ALL the radio buttons that have an active selection ALSO fire an rb_CheckChanged event (see application log below). On subsequent radio-button
clicks, only that RB fires the event (as expected).
This behaviour is having a dramatic impact on performance. The page loads quickly, and a "normal" RB click provides an AJAX update correctly within 1 second. The problematic first RB click, however, takes up to SIX seconds to process, which is unacceptable from a user experience standpoint.
Developed in VS.NET 2008, ASP.NET 3.5. Also I converted the "Web Site" solution to a "Web Application" (pre-compiled) and got the same performance (still too slow). Release builds run only marginally faster than debug builds.
Why would a single RB selection change cause all RB's that have a "selection" set on them to also fire? (The "selection" is determined through database settings every time the control is populated, which is called from within the parent page control's Page_Load function. This selection is determined also at first page load, since all the controls get populated then, so why would the clicking of an RB cause them all to fire an event, and only once? That's what I don't get...)
Not sure if this is an AJAX issue, or general ASP.NET UI issue, so I'm posting in two forums on this one.
I'm at my wits end on this one looked/Searched/Played/Experimented and I need your help if you can.This page is going to be primarily used on a mobile device using Win Mobile 5 Need to Accomplish:Prevent Postback(serverside) of Page using JavaScript (Postback's slow down the page on mobile device)

I am using JQuery for all of my client side validation and Asp.net validator controls for all of my server side validation. I am using an errorlabelcontainer to store the client side validations in a summary at the top of the page, which is the requirement. All works well. My problem is, I want to display the server side asp.net errors in the same errorlabelcontainer OR display all of the client side errors in the validation summary. Either way, Both errors need to be in the same place/div. Any ideas on how to do this? I thought of maybe using the asp.net validation summary as the errorcontainer in JQuery, but I cannot find the summary. This is what I have right now.
$("#aspnetForm").validate(
{
onkeyup: false,
errorLabelContainer: $("ul", $("#FormErrors")),
wrapper: "li"
});

I have used the Javascript Menu template from Sothink and embedded it in my Master Page. Now when I click on any control of a form like a Radiobutton or a Linkbutton, etc. the Side Javascript Menu disappears. I don't understand why. Initially it shows but later disappears on clicking a redirecting control.
View 1 RepliesI've always depended on putting a control on an aspx page and double-clicking in design view to create my VB page. But this isn't happening in my current project. It creates an inline script in my aspx page instead. Where is the option or preference or XML file or.... that controls this?
View 5 RepliesI have a simple question - I use update panel with custom server control inside. I call __doPostBack from javascript and RaisePostBackEvent on the server fires (I implement IPostBackEventHandler).This is client to server call. Could I return data back to the client (after this partial postback)? What is the best way to achieve this?
View 2 RepliesBasically I want to get some javascript to be sent back to the client and executed from a postback inside an UpdatePanel. Furthermore this is inside of a reusable WebControl. I've tried
this.Page.ClientScript.RegisterStartupScript and this.Page.ClientScript.RegisterClientScriptBlock but Firebug shows that those scripts aren't sent back in the postback's response.
I also tried straight up writing a <script> tag inside the control's main div in the Render method, which does get sent back but isn't executed. I got a hacky solution working, but ideally looking for a cleaner solution. The hack is to add a 1x1 pixel img with width/height set to 0 and use that for an onload event to execute the script and that works, but it seems like there has to be a cleaner way to do this.
I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.
I'm having trouble with the following:
Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.
I encouter some postback issue when using GetPostBackEventReference. Here is the Scenario:I have a javascript modal popup dialog and got a button in this modal dialog which used to select things (this is NOT an asp:button control)
When this javascript dialog HTML button is clicked, it will call the MS AJAX web service call by the javascript: eval() method. And this MS AJAX web service call is dynamically generated. So the code is like this:
var serviceCall = svcCall + "(" + parameters + ")"; //dynamically generate the MS AJAX web service call here
eval(serviceCall);
//use eval to trigger the MS AJAX web service call
As you may all know, after complete the MS AJAX web service, you can define a callback function to handle the completion:
function OnComplete(result, userContext, methodName) {
//force to call postback manually
eval($(userContext[0]).val()); [code]...
As you can see, this is how I bound the asp:button (i.e. btnSelectUser) 's Click Event to the asp:hiddenfield using the GetPostBackEventReference, and set the registerForEventValidation argument to false. I have also tried to use different ValidationGroup and set the CausesValidation to false.In summarize, I bound the asp:button's Click PostBackEventReference(i.e. __doPostback(....)) to the asp:hidden field's Value attribute, and using javascript eval() to eval this hidden field's value in order to manually trigger postback.
p.s. the btnSelectUser is an asp:button control and used to call out the javascript modal dialog.
Ok, here is the Problem:In the same page, there is some asp:validator, e.g. and , and of coz, when the page run into error, this validator and callout will display to the user. e.g. When the user didn't fill in anything and submit the form, the ValidatorCalloutExtender will display a ballon and tell the user. Imagine one of this ballon/validatorCalloutExtender come out and on top of your screen at the moment.
Then you click the btnSelectUser (asp:button) to show the javascript modal dialog, and in the dialog, you Add some users, and once you hit the SELECT button inside this modal dialog, a MS AJAX web service is trigger as mentioned above, and once this web service is complete, it eval() the asp:hidden field's value (i.e. __doPostback(...))......and do the postback manually.
However, because of the validatorCalloutExtender ballon has display, it somehow cannot trigger the postback in this way, but when I close the ballon/validatorCalloutExtender, the manual postback using eval() is just working fine. Even more strange is that, when the ballon is displayed, the first time I click the SELECT button inside this modal dialog it doesn't fire the postback, however, if I do the same thing again (i.e. open up the javascript dialog, and choose some users, then click the SELECT button again). It able to do the manual postback....and I don't understand why the first time doesn't work.
I'm losing client side href. Is it possible to send it back to the server on the button submit using a variable or something?
View 1 RepliesI'm using five FileUpload controls on a single web form. Besides allowing the user to upload a file I also am collecting user data. Problem I run into is during the server side validation if any of the user data is invalid on a post back when content it redisplayed the FileUpload controls loose the client url that was selected when browsing. How can I keep that path or set the pathing on the control so they do not have to keep rebrowsing for the files on data validation errors? Right now breaking up the two form sets user data and file upload into two pages is being frowned upon and requirments would like it to be on all one page.
View 1 RepliesI want to enhance a composite control's client side, my approach is to recreate all method on JavaScript, so here I have some troubles:Can I call onclick event on client side otherwise on server side?the statement table.onclick=SelectRow(event) fires a bug!Code:

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)
<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...
There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)
<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...
There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.
<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");
[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

View 1 RepliesI Have a TreeView that I populate from a DataTable.Once it has been populated, I Cache the Treeview.If I try to add the cached TreeView control to my page, nothing happens. No errors no nothing.If I create an empty TreeView control on the page and do a "Do Until" loop and add each node to that empty TreeView, that works! but only once. The next time it loops, for some reasion the CachedTree.Nodes.Count = 0.I can't see what I'm doing wrong.

OK, here's my scenario. I inherited a website and I'm dealing with a quirk. I have a page that has a repeater with auto postback controls in it. And also a hyperlink or a button to open a RadWindow to add a new item or edit an existing one, the repeater probably could have been a Gridview, but forget that for now.
If you use the button to add a new entry or the hyperlink to edit, it works fine and closes and refreshs the page. BUT, after you click ANY of the auto postback check boxes and THEN try and use the new button or edit hyperlinks the RadWindow works, but on clicking SAVE or CLOSE it throws a dialog box in IE and Firefox letting the user know that:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."
IE's message is similar. Clicking RESEND works fine and everything is ok, but its a bit distracting to the user. The RadWindow open a page that has THIS javascript in it:
function RefreshParentPage() {
I Simply drag a button from the toolbar onto a new page with a master page and a title, double click it so that I enter the Button1_Click function and sets a breakpoint and add some random code. The breakpoint nor the code never fires. I've tried this on several different pages and controllers, but with the same results: The page reloads, but no code is run. I Have Tried:
Ive tried with three different webbrowsers with all plugins disabled. I've tried to turn of Causes Validation, - Nothing changes. I've tried to clean and Rebuild the project, - Still nothing. I've tried to create a whole new project, -Does'nt work there either. Other Information: A RadioButtonList OnDatabound Event works, but whenever i try to do a Button or ImageButton click event the code for the event never fires. Ive programmed several webapplications in other versions of visual studio and ASP.NET but I have never encountered this problem before.
Breakpoints work in other parts of the code and the compile settings is set to DEBUG.
* Visual Studio 2010
* ASP.NET 4
* MVC 2.
Am I supposed to file a bug report or does anyone out there have a solution?
I am tring to send form values to a page from a user control. I included the user control in a master page.When i use page.previouspage it can not get value. is there any way to send form data to a page from a user control included in a master page?
View 5 RepliesMaybe I've picked a totally inappropriate/bad example. What I have is a user control that contains a bunch of dynamically created Telerik RadGrids. My user control is added to a couple of Telerik RadPageViews that are part of a RadMultiPage that is used alongside a RadTabStrip. What I need to do is call a Javascript function in my usercontrol to update it's display whenever it's parent RadPageView is selected.
So basically I have the following Javascript code:
function OnClientTabSelected(sender, args)
{
// Get the MyControl that is on this tab
var myControl = $find("whatever");
// Call a method that updates the display
myControl.doSomething();
}
I am using ajax tab control,is there anyway to switch from tab1 to tab2 on client click of any element?
View 1 RepliesWhat I'm trying to achieve/plan, is whereby a page loads with a set of inputs, e.g. TextBox, Radio List etc. Taking TextBox as an example, there is a button for the user to "Add" another textbox to the page (in the same group), e.g. Member1, Member2, Member3 etc etc.
Two questions:
I could add these with Javascript, however the resultant "save" on postback would not get these inputs? If so, how? The form needs to work without Javascript as well, so postback to dad another control is fine, however if I click the "add" button again, it will only ever add one control.
protected void btnAdd_OnClick(object sender, EventArgs e)
{
holder.Controls.Add(new TextBox { ID = "txtControl1" });
}
I don't know why i can't call the javascript function after clicking the button.
protected void clickSave(object sender, EventArgs e){
ClientScript.RegisterStartupScript(this.GetType(), "MyScript", "function_me( "" + Strname + "");", true);
}
