I am needing to cancel a picturebox from loading. However, I need to cancel is from loading using the imagelocation command.

what's the best way to stop a form from displaying in its Load event.I initialise a form using the following code:
Dim MyForm as new MyCustomForm
In the Load event of MyCustomForm, I ask the user to select a folder and use that to populate a listbox on the form.folder.If the user presses Cancel instead of selecting a folder, I don't want to display the form. Right now, I just call Me.Close in the Load event, but that still causes the form to briefly appear and disappear in the background. Also do I need to call Me.Dispose?
I have an web application of 200 web pages and all has a single master page. Most of the content pages use AJAX controls so most of content pages has its own ScriptManager. Now I have a requirement to add a link with HoverMenuExtender control and for that I need to put ScriptManager in the Master page, but it is working only in the content pages where there is not ScriptManager.
View 1 RepliesI have an ASP.NET form with a cancel button that is supposed to, after confirmation from the user, redirect them to another page. I'm using javascript for this. It works fine in a simple HTML page, but apparently something is interfering with it on the .aspx page. The popup message works perfectly, but clicking "Okay" does not take you to another page. I have tested the if statement and it is working correctly, the only thing it won't do is leave the current page. [code]...

View 3 RepliesI have a popup aspx page that receives data from a parent page gridview Edit click. There is a great deal of parsing of data from parent page to pop up as the data is being translated in pop up, then sent back to parent page to be reassembled in the original text block before update.
When the popup passes the data back or is canceled, the parent page gridview is still in Edit mode.I would like to pass the Cancel or Update button click from the popup to the parent page gridview so it can complete the update or cancel event without asking the user to click the corresponding command button link from the gridview edit mode, to Update or Cancel.
UPDATE: There is also a jquery UIBlocker on the Parent page to prevent the user from returning to the page until the PopUp page processing has been completed. Below is the critical code:
PARENT Page:
function parentFunc(a) {
// Unblocks on return from popup page.
$.unblockUI({});

Had a problem with preventing the popup from reloading. So there is an if condition in the load event. A dynamic number of controls are built on the popup as literals. So the Page Init event and Page Load event fire on non Postback to rebuild the controls.
I validate a DataGridView with the CellValidating-eventhandler.That works fine. However, I want to avoid validating when the user presses the Cancel button. In the sequence validation occurs before the event CancelButton.Clicked.

I typically write my own servers, javascript, etc in vi. I've been given a project to enhance a VB.Net / ASP.Net application and I'm having some troubles figuring out how to get the user control to render BEFORE the page finishes loading.When I use normal browser as the viewer, everything works OK. When I try to use generate the page as a report, the report generator spits out the PDF while my JavaScript graph drawing stuff is still in it's initialize functions.They are using EvoPDF as the PDF generator. It appears the page is being considered complete after the page is loaded but before the javascript is executed.I admit I'm a bit lost when it comes to ASP.NET, but I know HTML/HTTP/JavaScript very well.How can I force the page load to wait until my usercontrol finishes rendering?

View 4 RepliesIs there a way of stopping the main page waiting for a usercontrol to load before it can finish loading?
I have a usercontrolthat has to do a lot of DB calls which can take a few seconds making the page slow to load. Ideally I'd like the main page to load straight away and then the usercontrol content appear when it is ready.
I have been tasked to do a project, and have been given a list of links from the client - what the Project needs to do is:1 - open google with a specific search phrase - no problem2 - look on that page for any links containing any member of the list of links, if found, invalidate the entry in the list, and auto-click the link, then go back3 - repeat for any other "finds" on that page4 - when done, auto-click on "Next" (no problem) and go back to step 2For now, I am not even attempting to auto-click the found link and go back, I am just listing all found links in a TextBox. The problem I am having is waiting for the next pages to load before looking for a match in the list of links. I tried using webBrowser.DocumentCompletedto set a Boolean - I tried testing WebBrowserReadyState in the DocumentCompleted event ar the code below gives the best results but it is inconsistent, meaning it completely misses some pages that I know have links on them that match.

View 4 RepliesI've discovered a problem that's fairly huge in my work environment and unusual. I'd say that it's impossible for it to be happening except that it is happening.
You have a window (we'll call it window 1) open with a page in it, you enter some data on the form, push the button to submit the data...behind the scenes a decent amount of work is going on.While data is processing in window 1 , you open window 2 and try to load the same page that is processing data in window 1.Window 2 will not render the page until window 1 is done doing whatever it's doing behind the scenes and has re-rendered on the screen.This is happening for all .NET pages in our environment.
