Sometimes The Page Does Not Load Fully After An Clientscript Alert()
Mar 31, 2010
The problem i have noticed is that sometimes after a clientscript alert() the page will not post back properly and kind of "hang". The page will only show the background and will not do anything until the browser is refreshed.
[Code]....
I call clientscripts withing button click events, after the code has succeded or failed(try catch). So i will write to database/upload file/send email and then depending on the restult run a clientscript alert to notify the user. However sometimes after you "Ok" the alert the page does not finish posting back and "hangs" half loaded.
how to fix it? would adding return false; after the alert in the client script at all? (i have seen this in a online code example but they did not explain why they put it there).
Have a GridView in an UpdatePanel, all works fine. Click the Submit() button which updates the database on postback, then the GridView is bound in code and I register an alert:
Calling UpdatePanel1.Update() causes the popup to appear. All fine but what I am noticing is that the alert occurs just before the page has fully updated and is causing a few minor layout issues that are resolved when the alert button is closed (by clicking OK). Is there a way to generate an alert after a full UpdatePanel refresh, so something like:
function SetScrollEvent() { window.scrollTo(0, document.body.scrollHeight);}
I update update panel from server side like below.
protected void rptList_ItemCommand(object source, RepeaterCommandEventArgs e){ //HiddenField hiddenId = e.Item.FindControl("hiddenId") as HiddenField;Label lb1 = e.Item.FindControl("Label2") as Label; //Button bt = e.Item.FindControl("Button2") as Button;if (e.CommandName == "myclickevent"){ // your codes here...SqlConnection conn = new SqlConnection(constr);SqlCommand
[CODE] .....
I use repeater and repeater have button on button click i update the update panel. now where i have to call the javascript function so that it execute after update panel fully loaded. I want to call javascript function after page fully loaded.
I am new to .Net and webpart. What I try to do is to create a griedview webpart with a functionality of export to excel. The gridview also can drildown another gridview. The drilldown work as expected. When click export to excel link button it works ok, too. The problem is when comeing back to the gridview to click any row, it stops to drilldown. If I want to use export to excel link it stop working also. Only refresh page can make it work again. I did research and found a solution, that is, to implement a javascript to solve the problem. I follow references from microsoft site as shown below.
My page loads scripts and css from some custom assembly. For now, I use the ScriptManager to add scripts to the page (its CompositeScript) and the page's ClientScript.GetWebResourceUrl() for css files. So, on the page(s) my scripts are referenced by /ScriptResource.axd and css are referenced by /WebResource.axd. Works fine except the fact that those URLs look really ugly. Is there any manageable way to replace those urls with my own fake paths without moving/hosting script/css physical files somewhere?
When user cliick on the control before page fully loaded it goes to error page.
Following is the trace.
Execution Error
Invalid postback or callback argument. Event validation is enabled using <pages enableEventValidation="true"/> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
i want to call javascript function from codebehind using page.clientscript it is working fine if i am not using AJax's Updatepanel,but if i want to use Update panel, but the same time i want to call javascript function from codebehind
I have an .aspx page which seems to load OK upon initial load, but if you refresh the page it will not fully load (yet the browser indicates "done" in the lower left status bar).
I have this problem in loading contents of the site where there's a certain time that those elements that supposed to be hidden are shown for a while before the page is completely loaded.
Everything below the dropdown is supposed to be hidden and they show atleast a second that is very noticeable, that I still have the time to have a screen shot. Below is when the content is completely loaded.
Everything inside the content is inside an UpdatePanel, and I am using a jqTransform to transform the form elements. I know that jqTransform is called after all elements is loaded, but I just don't understand why it is showing the hidden elements before the page is completely loaded.
Is there any work around this one that I will only show directly the completely loaded page instead of showing the hidden elements before hiding them?
FYI: Elements hidden will be shown according to the value selected on the dropdown. If the element is hidden before the jqTransform is called, once I show them back, it is unusable or cut off.
We were having occasional reports where the value of a set of DropDownBoxs in a GridView would be reset to the first value item in the list.
We finally tracked it down to a timing issue where a user would click Save before the page finished rendering/loading the data, and we are able to repro it on the production server but not locally because the page loads too quickly.
How would we go about detecting this on the server side to know the data returned is invalid or otherwise stop from setting data that the user didn't set?
I have a huge content on a page which scroll's down vertically and when I try to popup a modalpopup control on this page, some part of the screen is not grayed out on IE6 and user can interact with the background page ( even when modal popup is open) . This happens only on IE6 works fine on IE8 and firefox .
I have a page that downloads a dataset and streams the output to an Excel file by modifying the response headers.
I want to write an AJAX call on the client side that can display a modaldialog while the file is being generated and dismiss the modaldialog when the file has been fully rendered.
I can turn the dalog on when the user clicks a link, but for some reason my pages return readystate 4 and status 200 prematurely. (These are the codes that say the page is done)
Because this is happening, either the modal dialog is dismissed immediately or I need the user to dismiss it.
Has anyone seen this before? Is this an issue with streaming a file instead of hitting a physical page?
Does anyone have a work-around, or will I need to have the user manually dismiss the dialog?
I hv Declared two Master page one Is Base and Derived.. Base Page Load is working but when i hv written load controls in Derived Page Load Using C# it's not working..
Scenario is I have a application relative url like "~/path/to/page.aspx?query=string". I need to programatically create a web request to that page and currently using WebRequest.Create. The problem is WebRequest.Create requires a fully qualified url including the protocol/domain/port etc.I have access to the current Request.Url object but there doesn't seem to be an easy way to get just the base url keeping the protocol (HTTP vs HTTPS) as well as any port numbers as well as the path to the applicationI mean all the info there, so if need be I could just take all the parts and combine them but it seems like it might be error prone and it would be great to have something built-in that's well tested to do the job. Page.ResolveUrl gets me almost there, but it's missing the protocol and the domain/port.
once the user clicks tje button he is redicected to logout.aspx page.
on the page_load of this page(logout.aspx) i am terminating the session using Session.Abandon();
when the user clicks back button of the browser as the sesssion is abandon i want to show the alert message and then redirect to other page.
instead of above it allowing the user to again redirect to logout.aspx page.(the operations are not reflecting on the database when he clicks back and tries to select the radio button).
below is my code
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data.SqlClient
and it itself works fine i.e. the message box is shown.
But e.g. with Firefox when the user does not immediately click OK-button on the alert message, the page stays dimmed after the alert box has gone. With IE 8 this seems not to happen (or is very rare).
I have a page that produces some Javascript to display an alert and redirect the page. I also need to produce an Excel spreadsheet. However, when the Excel spreadsheet produces it seems to stop the JS from working. If I disable the Spreadsheet the JS works fine.I'm producing the Excel document like so:
I am trying to create a progress bar for page load as it takes long to load. I need help to resolve jscript error 'null' is null or not an object on line $get("btn").click();
