is your page load event called ? please check.
if yes then please check have you set any default check for checkbox/radiobutton in page_load ? because checkbox/radiobutton server side event not fired when checked property is set to true
Or you can Get it inside an update panel, with property "ChildrenAsTriggers" on true

Nothing. The browser should intercept this key code and open a new tab/window as the case may be.
|
|
|
|
|
so if any one want to identify this event using c# or any median. what is the procedure. actually i just want to identify this event and prevent user to open a window in new tab. many people suggest me to add javascript to disable ctrl, but i dont want. becoz the requirement to open the cut, copy, paste option but prevent user to opening new window in new tab or new browser window.

I do not think there is a dependable way from a plain vanilla scripting to interfere with the browser's engine itself.

If your application itself is running in a popup window then you can control the key sequences. Then you may need to provide CTRL+C and CTRL+V yourself as the case may be appropriate.

Please how can I create group box in asp.net to group controls together. Also, I want to know how to style web forms in asp.net. Thank you.

You would style forms using CSS.
You can use a div to group controls together.
We'll need something more specific if you are looking for a more specific answer.

Hi.
I can't figure out how to implement this as I am new to asp.Net.
I am building a Library Management System in asp.Net using C# and SQL Server 2008 r2.
There will be a Book Issue and Return Date respectively for each book.
Now my question is How can I enable the Application to automatically add a numeric value to SQL Database on the expiration of the Return Book Date( Note that the Return Book Date will vary )
SQL Job scheduling was suggested but I think it does not meet my requirements as in my case the Date after which the job will be executed differs i.e the Book Return Date for each book.
Any suggestions will be helpful.
Thanks
|

|

If you're just looking to calculate the number of days the book is overdue, it would be better to calculate the value as required:
SELECT
...
CASE
WHEN ReturnDate >= GetUtcDate() THEN 0
ELSE DateDiff(day, ReturnDate, GetUtcDate())
END As DaysOverdue
FROM
Books
Otherwise, set up a SQL job to run every night to process the books which should have been returned on the current day.

I wrote a simple ASP/C# website using dynamic creation of controls, but when I updated VS2013, my project started having problem with displaying controls.
The problem is as follows:
http://i.imgur.com/KAwTy3e.jpg[^]
-On start, the page looks ok, but when I press any button (postback), the table on may page disappears, but the controls in cells are staying, but not in place because table disappeared, but one under the another. So the page breaks in half in my case.
It looks like this:
My Code:
public partial class _Default : System.Web.UI.Page
{
Table TblMainTop = new Table();
TableRow TblRow_Top = new TableRow();
TableCell TblcT_Logo = new TableCell();
TableCell TblcT_Status = new TableCell();
Table TblMainCenter = new Table();
TableRow TblRow_Center = new TableRow();
TableCell TblcC_Control = new TableCell();
TableCell TblcC_Source = new TableCell();
PlaceHolder PHolder = new PlaceHolder();
Control LOGO;
Control STATUS;
Control CONTROL;
private void Create_MainTable()
{
LOGO = LoadControl("~/LOGO/Logo.ascx");
STATUS = LoadControl("~/STATUS/Login.ascx");
CONTROL = LoadControl("~/CONTROL/Navigation.ascx");
TblcT_Logo.Controls.Add(LOGO);
TblcT_Status.Controls.Add(STATUS);
TblcC_Control.Controls.Add(CONTROL);
TblRow_Top.Cells.Add(TblcT_Logo);
TblRow_Top.Cells.Add(TblcT_Status);
TblRow_Center.Cells.Add(TblcC_Control);
TblMainTop.Rows.Add(TblRow_Top);
TblMainTop.Rows.Add(TblRow_Center);
TblMainTop.BorderWidth = 5;
PHolder.Controls.Add(TblMainTop);
PHolder.ID = "Test";
UpdPanel_Main.ContentTemplateContainer.Controls.Add(PHolder);
}
protected void Page_Load(object sender, EventArgs e)
{
this.Create_MainTable();
}
}
That’s how it looks in browser before postback:
<div id="UpdPanel_Main">
<table id="tojeID" border="0"
style="border-width:5px;border-style:solid;">
<!--
</table>
</div>
That’s how it looks in browser after postback:
<div id="UpdPanel_Main">
<style type="text/css"></style>
<div id="ctl03_PnlMainLogo"
style="height:221px;width:1171px;"></div>
<style type="text/css"></style>
<div id="ctl04_PnlMainLoginState"
style="height:221px;width:529px;"></div>
<style type="text/css"></style>
<div id="ctl05_PnlMainNavigation"
style="width:301px;"></div>
</div>
Here you can download light version of my project:

Can someone gave me any advice ? I don’t know what is going on.

It is no use to me becouse i want to update my page all the time and it was working before as intended, and now it is not with no reason.

You need to understand the page lifecycle.
When you create controls in Page load, they only persist 1 time. When the page post back to the server, the controls in page load will lose there values because there created again, or may not be created at all.
You need to create the controls in page.init, so the controls persist during postback.

Changed code as you suggested:
protected void Page_Init(object sender, EventArgs e)
{
if (Page.IsPostBack)
this.Create_MainTable();
}
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
this.Create_MainTable();
}
But the effect is the same - table disappears but the cells are staying one under the other.
Any other suggestions ?

I write in VB, but I wrote this as a quick example and tested it. The controls persist throughout the page life cycle.
Perhaps this example will give you an idea of how to write controls in code behind so that they persist.
I'm curious if others read this post, I use the With statement to include stuff like control properties.
I was not able to figure out how to use Style in the curly brackets like in the update panel, and was forced to use the control variable name instead. Lots of extra typing. If anyone knows how to add style using the curly brackets let me know.
