I have insert page - data is getting inserted properly with all validations .But the main problem is that after insert if anyone clicks on the refresh button on the Internet explorer browser , data gets inserted again the same data which insert on submit button.
View 3 Repliesi m using Parameters .AddWithValue("@ ", .text) method t insert data from textbox to my data base. i m using SQL data base. primary key is auto incremented. problem is that when i click on submit button to add the data in data base, all the code works fine, and my data get inserted in database table. but then if i click on refresh page, same data get inserted again in the table. and if i click twice or thrice on refresh button data get inserted again and again. i solved this problem by redirecting the page to same page. but then i lost my view state of data. i want to keep the view state and restrict this insertion of data on refreshin. how can i solve this problem by keeping the view state.
View 1 RepliesI'm coding with VB.NET and have a webform that includes gridview. The gridview captures data via a db view. Also the view includes all the parameters of the tables.
The problem is: when start program, there is only 2 rows seen on gridview. then i can insert something successfully. And when i checked from db i can see the new data. But in my form, newly inserted data doesn't seen. Even i restart the whole program, gridview always shows only 2 entries.
I developed a web application in asp.net.I have a module for saving values to database after clicking the button event.Thats working successfully.After that when i clicked the browser's refresh button the values reinserted to the table each time.How can i avoid this .Which is the code for this solution?
View 1 RepliesI am dynamically creating dragrids in different rows of an existing datagrid in asp.NET
My generated datagrids have a column which is TemplateColumn (a CheckBox Column).
In my parent datagrid, I have a template column with checkboxes. when I check or uncheck the value of the check box, the check_change method is called (autopostback is set to true), the dynamically generated datagrids lose the checked checkboxes (the checkboxes are all unchecked again). However, if i check any of the checkboxes of the child (dynamically generated) grids and press F5, it refreshes the page but still I have my checked checkboxes.
What's happening ?? how is post-back different from refresh F5??? understanding this might help me fix my problem here :DataGrid not being altered!
Is there any way to get click event of refresh button of browser ?
View 4 RepliesI have an ASP.NET/C# application that exports some data into an Excel spreadsheet using COM interop at the click of a Button control. When I click the button, Excel is opened with the generated spreadsheet. For what it's worth, here is the button code:
<asp:Button ID="export" Text="Export to spreadsheet" runat="server" OnClick="Export_Workbook" />
This works fine, except when I click the button, close the subsequent spreadsheet, and refresh the page. When the page is refreshed after clicking the button, the call to Export_Workbook() is made again and so the spreadsheet opens again. Firefox, for example, says this when you refresh: "To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier." This is something I want to avoid.
I'm sure there's a better way to accomplish what I'm trying to do, I'm just not sure what the best approach is.
Edit
I've accomplished this by doing the following:
protected void Export_Workbook(object sender, EventArgs e)
{
Response.Redirect(Request.Url.AbsolutePath, false);
ItemList.Prepare_Workbook();
}
have looked around for an answer to this but not quite found what I need.
The main (home) page of my web app has a field on it indicating the last time an SSIS package was run. This is done under the page load event and the code reads a sql server table to pull of the date and time.
The problem is, if the date and time is updated and I then close teh web browser and re-open it and displays the main (home) page, the time displayed has not been updated. I have to either hit F5 or clear the temp internet files using the options under IE.
I found some code which refreshes the page automatically once every 5 seconds or at set intervals but this is not what I want to do. I just the page to be refreshed upon loading it.
In my .aspx page, I use a div including some repeaters and datalists without update panel.I bind all of them in page_load when Not IsPostBack condition is met.by default page is ok but if I push refresh button on browser regardless which browser or simply push F5 it shows header but not that div.

View 2 RepliesI have a Shopping Cart Summary User Control that doesn't update without a full browser refresh.
The scenario is:
I have a DataList in one User Control that displays Product data with an ItemCommand event for an 'Add To Cart' button.
[Code]....
When the 'Add to Cart' button is clicked, the page reloads and another User Control containing the Shopping Cart Summary should be updating. However, the Cart summary doesn't fully update until a full page refresh occurs.
I should add, that the Cart Summary is "located" on a master page whereas the Product List is in the Content Placeholder of a web form based on the same master page.
I can provide more of my code if required but I'm initially reluctant incase I'm making a noobish error!
In our application we need to handle browser close event. When a user directly closes the browser, we should give him an alert message and stop him by directly closing the window based on some conditions. This we have handled through body onunload event. The problem is we are getting the alert message but after showing the alert message the window gets closed.
Is there any way to stop closing the window on click of browser close event?
And also when the page is refreshed, the last performed action is getting fired again.
Project
I'm running a single page (default.aspx) web site in Visual Studio 2010. I have a few other projects in the solution, but they're all taken out of the build queue at the moment. I'm using Visual Studio Development Server as the web server (I haven't tried IIS yet). I'm using the HTML5 Boilerplate from [URL] I'm testing in Chrome and IE8
Problem
Visual Studio 2010 is outputting "Debug" information to the Output window every time I refresh my browser. Whilst this isn't a problem in itself, it seems to be extremely slow in doing so... it takes around 4 seconds to show the page in full from initial refresh.
I've noticed that the "Script Documents" folder appears in my solution view, and some files (notably JS files) seem to take a while to show up. I've tried removing all the JS and CSS file references from my page, but it still does it.
So, to troubleshoot I've created an index.aspx page with no content apart from the generic ASP.Net template code, set this as the start page, but it still takes just as long to load up as the other page.
As a last resort, I've created a new project and tried it with no changes to the default page - still the same, takes a few seconds to finish loading in either browser.
The strange thing is that this happens even when I stop debugging in Visual Studio and browse directly to the URL on the ASP.NET Development server.

I need to implement a "preview" functionality where people make changes to a form, click a button and a pop-up window displays the preview while the original form retains the user's changes in the various <textarea's. Right now, the preview is working, but when they come back to the form, their changes are gone, the page has refreshed. How do I prevent the page from refreshing? I need to go to the server to get the URL to the preview page.
