I am using if (document.getElementById('<%= MainImg.ClientID %>').complete) {
hideLoadDiv();
}
to hide a div which indicates the image is not loaded yet,but it hides before the image has finished loading and is shown, while the browser is giving me a message that the page is still transferring data from the server :S
Is there another function I can use to make sure that the image is fully loaded?
How can you determine if your page is fully loaded in asp.net c#?
View 6 RepliesI am struggling a little creating a basic redirect page in ASP.Net but ensure the HTML is loaded first.I tried putting Response.Redirect in the page load event but that fires before the HTML is fully loaded. Been trying to use a timer but just not doing anything.I need the HTML to load before the redirect occurs is I have a statcounter script installed to log the visit before it redirects of my site.

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:
ScriptManager.RegisterStartupScript(this.UpdatePanel1, typeof(string), "dopopup", "alert('Operation successful!');", true);
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:
ScriptManager.RegisterFullyLoadedScript(this.UpdatePanel1, typeof(string), "dopopup", "alert('Operation successful!');", true);
I tried a simple wait() in the code like this:
ScriptManager.RegisterStartupScript(this.UpdatePanel1, typeof(string), "dopopup", "wait(100);alert('Operation successful!');", true);
But this didn't work.
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 class called 'Tutorial'. At the top of my page I declare the object as below: [Code]....
The last thing I have is an Add and Save button and what I would like to achieve is add/update the record based on if it exists or not. To do this I would like to check the state of the tutorial object to see if it has been loaded and use its id without needing to put it on the page for reference later.
Will the tutorial object still contain values after postback and how can I check if its been declared?

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 am in charge of converting an ASP.NET web application into fully AJAX based application. I know Javascript and Jquery very well.
Initially I thought to point every anchor tag's click event to JS function and to call stuff via ajax and to populate the body and so on. I encountered a problem when it came to ASP.NET Form on every page and when there was need to make a post-back. I decided to point every Form tag's onSubmit event to a JS function to post stuff using ajax and to get results and I got to know this is not possible with ASP.NET as every time where is a button click, there will be post back so it's hard to let page know what button was clicked.
I then decided to use ASP.NET built-in AJAX controls to use with Forms which is pretty easy and worked like the way they should. Now I am stuck with the question of which I should go with?I like to be JS way because it's more customizable than AJAX.NET.
I am showing images of members on my website. The images are already saved to file. I want to add some text to the image that is loaded in the image control. I don't want to save it to file, just display the change on that web page. I have seen code on how to do this but I do not see how to load it into an image control. Is this possible without saving it to file?

In trying to upload images to a server, I often get the following error "Maximum request length exceeded.".
I have tried to check for the size in codebehind but it appears that the error comes from the service provider or something else because I never even get to debug it since the error appears even before the Page_Init Subroutine in codebehind.
What is the best method of checking for the image size and then resizing it dymamically to a maximum file size as well as length and width size.
how would i check if the file path already exists in javascript
View 1 RepliesI've been working in asp.net webforms and I've been making a UserControl that depends on a small bit of javascript which is in an external file.
I want to be able to put a reference to the javascript inside the UserControl to ensure that it gets loaded on the page, but the problem is that the UserControl can appear multiple times on a page so I only want the script to be loaded with the first instance of the UserControl.
Is there an easy way to do this in ASP.NET Webforms?
