It's bad idea to block the keys. You might be able to do this with JS, but it's not reliable. Why you need to block users opening pages in new window ?

Yes. But a better approach would be the following.
1 - When user opens the page, we set a flag in DB
2 - Page load, this flag is checked to ensure only one page is running.
3 - When user finishes the operation, reset the flag.
4 - A scheduled job should run frequently which checks the flag value and the time it has started. if it is more than timeout limit, reset the flag.
What do you think ?

You may need to entrap the keycode for CTRL+N in keydown event and NULL it.

When user is idle for 30 minutes, he will be redirected to login page when he requests again. What problem are you facing ?

Thank you for your reply..
But I need to redirected to login page without making any request again..
ie when the idle time reach 30,automatically go to login page without any hit from user.
is it posiible??

You can do AJAX request to the server. If timeout limit over, redirect using javascript. But this method is not reliable.

Hi,
I wrote a function for dynamically create some bound columns and template field in grid view.The template field having check box in header template and item template.
First i have called this function on Page_load (!IsPostBack).
This will work fine.
Then i have checked the check box and click on a button(for delete the checked rows), the check box disappers.After the click event,if i am trying to access the check box from page load ,it returns null.I couldnt access the dynamically created checkbox .
Why it happening? How will i solve this problem?
Thanks

See when you click a button or and the page loads what ever is there inside !isPostback will be discarded.
You will require to call the binding function in the button click event to get it created again. Or put it outside !IspostBack

Hi,
Thanks for you reply.But there is another problem. In the buttton click, all other columns expect template field is there as such. The template column is there ,but the control is invisible.If i am creating the control outside !ispostback then i couldnt get the checked row for deletion.
How will solve this.

Are you creating dynamic controls ? If yes this would be a viewstate problem. Controls created in page_load event won't maintain viewstate. Try any event which fires before viewstate is saved.

DataGrid is a server control. When page is processed, it calls Render() method in each control which writes it's output to the response.

{
ControlCollection controlCol = row.Controls;
foreach (Control con in controlCol)

Type.GetType(con.ToString());
}
}

3.I face a problem in Sql Query. I have an application where user can change his/her address.

SqlCommand MyComm = new SqlCommand("Insert into ADDRESS_Table (ADDRESS1,ADDRESS2,ADDRESS3,ADDRESS4) values ('" + txtAddress1.Text.ToUpper() + "' , '" + txtAddress2.Text.ToUpper() + "' , '" + txtAddress3.Text.ToUpper() + "' , '" + txtAddress4.Text.ToUpper() + "')", this.MyCon);

If anyone have the solution plz help me.

1 - ^\s, I guess. But that doesn't prevent entry, it shows a message. You use jscript to prevent keypresses
2 - Then set it to be disabled, and only enable it when you change the value
3 - your code is a disaster, you should read up on SQL injection attacks. Fixing your code so it's safe will also fix the issue you're having.

<asp:textbox id="strDate" enabled="false" onkeypress="return false;" runat="server" cssclass="bgcolor" width="100px">
if (!document.layers)
{
document.write("<img src="cal1.gif" onclick="popUpCalendar(this, Form1.strDate, ">
\"dd/mm/yyyy\")' height=17 width=18> ")
}
</img>

^[^\s]*$ this won't match text with spaces or line breaks.

You should use parameterized queries or stored procedures to avoid them. Do a search for SQL Injection attack in CP - You will find useful articles.
