View 10 RepliesI want to be able to (in code) tell the page to refresh at that point ignoring anything else it was going to do.
Explanation:
I have a property lets call it AllUsers
AllUsers
{
return Database.GetAllUsers();
}
Now I have put it like this because in my code I want to just use this property to browse all the users and not have to check if its null or not up to date. The problem is if my method .GetAllUsers() throws an exception e.g. database is unavailable. If this happens I want to display a message to the user and reload the page to its initial state.
e.g. something like this
AllUsers
{
try
{
return Database.GetAllUsers();
}
catch(Exception e)
{
AbortAllCodeAndReloadAndDisplayMessage(e.Message);
}
}
Now I can reload the page using Response.AppendHeader("Refresh", "0;URL=ThisPage.aspx");
but how can I abort all code? because if I use this where I have placed my method the code will run and then reload on the next page load.
Should I change by property design? I wanted to have a property which would always be valid and up to date so any code using it wouldn't have to worrie
I am debugging an ASP.Net C# application in Visual Studio 2010, the application is running and execution is currently stopped at a breakpoint. How can I stop the page execution without "Terminate All" or killing the debugging process altogether, similar to what would happen if an unhandled exception was thrown? The "Break All Cntl+Alt+Break" option is grayed out in the Debug menu.
I want to stop the app from running but not have to go through a compile/start again. EDIT: I want execution to stop, not break, so that the page finishes loading and I don't continue running the application from the breakpoint forward. I've looked through the Breakpoints panel, the Debug menu and have right clicked all over but still haven't found the right option.
explain to me the difference between these two? I'm new to MVC and can't seem to find an explanation anywhere.
View 3 RepliesI want to pop up a message box when page.isvalid = false. How to do that?
[code]....
I am a bit baffled... I had my validation working fine till I added a validation group to it. Can someone tell me what i might be missing ? I'm at a loss... As I have another page doing the same thing and it works fine. Page.isValid always comes back as true.( I am just clicking on the button to make all the validation fire off.... )

I have cause validation true on button. And I am checking the Page.IsValid in c# code. But its always returning false value?
View 2 RepliesI am using a wizard control in which I have a next button that has causes validation = true. I also have a checkbox that when changed, in the event handler, I set causes validation = false for the next button. When that button is clicked - I get the following:
Page.IsValid cannot be called before validation has taken place. It should be queried in the event handler for a control that has CausesValidation.
Here is the code:
protected void chk_CheckChanged(object sender, EventArgs e)
{
CheckBox chk = (CheckBox)sender;
ImageButton ibtnStepNext = (ImageButton)(this.WizardSummaryTemplate.CustomNavigationTemplateContainer.FindControl("StepNextButton"));
ibtnStepNext.CausesValidation = (!chk.Checked);
}
What would be the recommended solution to disabling validation for the next button so I don't see this error?
I have a situation where in, one of the form has to show some processing message on the Page and then automatically redirect to another page.

The following setup seems to work fine on the client side, however when I post back and check Page.IsValid, the value is false. I also looked at mevDate.IsValid and it's false. It seems that setting the CultulreName on the MaskedEditExtender is sufficient to get the MaskedEditValidator to emit the correct JavaScript, but on the server side of things it doesn't work. When I flip CultureName to "en-US" everything works as expected.
My database insertion is working good with normal asp.net page but when it is a content page of master page, stucking me to insert data in database.
take the advantage of SQL Server Profiler to accomplish it, but I don't know anything about sql profiler. I only know about stored procedures but don't know what is sql server profiler?

I was wondering if there was anyway to populate the page with asp.net code like "<asp:Repeater ID="rptProducts" runat="server">MORE_CODE</asp:Repeater>" and then have the server use that code on the page. I'm not sure if i'm making sense. Like writing the asp.net front end code to the page dynamically before the .net engine generates the output html.

View 7 RepliesI have at text box with a validator control which works fine (prevents letters being entered, only numbers)
However once it displays the error message I am unable to do anything else on the page, links don't work etc. I have to close down the window and start the website agin.
I want to show a processing image on every page load how to do that...Not only in button click it should happen in all page load. It should start when page load starts and ends when page load completed.
View 1 RepliesI am able to route my urls to an existing page. Here is how our scenario is currently working:
On Default.aspx, we have several links that link to pdf files on the server. The filenames of these files change dynamically which is why we need the url routing. When the user clicks on of the urls, the link is routed to the getFile.aspx page that has logic in it to determine which file to open.
Is there a way to have the getFile.aspx page to open in the same window as the default.aspx page?
Otherwise, I need for the getFile.aspx page to close after the intended processing is complete, and I've not been able to close it without getting the close window dialog box. I figure if it opens in the same browser window, I can redirect back to the default.aspx page when processing is finished.
I am using ASP.NET 2.0 with C#(No AJAX) in my project. In a particular web page, when the a button is clicked, some server intensive C# code runs before the same page is displayed again with the results. While code execution happens on the server in response to Button_Click event, a blank white page is shown to user on his browser in between post backs. How do i show a message in this case, that the processing is still going on and ask the user to wait? I have used javascript to show a message on page unload. But this message is also erased when the page is posted back to the server and the user sees a blank white page on his browser. How do i avoid this white page? Is there a way to show a message in the blank white page? How do i show a processing Message while the page is loading upon on Post Backs to the same Page.
View 1 RepliesWe are in the process of building a huge site. We are contemplating on whether to do the processing of HTML at server side (ASP .Net) or at the client side. For example we have HTML files which acts like templates for the generation of tabs. Is it better for the server side to get hold of content section (div) of HTML load the appropriate values and send the updated HTML to the browser or is it better that a chunk of data is passed onto client and make Javascript do the work?

Is it possible to stop redirection at hyperlink to another link page?
As we do in IE toolbar, when we select the hyperlink element, the toolbar highlight the hyperlink but doesn't dispatch the redirect event, i need the same behavior in my html code.
I have an ImageButton programmed to open up a new window with a small onclientclick javascript routine. But, when the ImageButton is clicked, the page containing the button reloads too, causing both a delay and loss of position on the page. I don't need the page to reload, just the new window to open.

But everytime when I filter and click on button, page loads and scroll upward then again to see the filteration result in Geo Map, I had to scroll down my page.I want that when I filter any station and click on button, page should stick to that GeoMap section. It should not go upward until user scrolls the page.For this I tried using "Update panel" but then GeoMap javascript is not working.
View 1 RepliesI am using an application called "SAFE" from ASP. This application using for enter the aircraft and personal injury accident.
Once we enter all the details and click the submit button. The next page will open and show the message details like report number.
Report Number will generate depend on sequence.
If you press F5 or refresh in the same page, get the pop up message "Retry" or "Cancel".
If click the retry button, the same input details is saving and generating the next sequence report number.
