What's wrong in the following statement.

if ((Convert.ToInt32(e.Row.Cells[2].Text)>=15))&& (Convert.ToInt32(e.Row.Cells[2].Text)>=17))

You have an extra bracket, it is suppose to be if ((Convert.ToInt32(e.Row.Cells[2].Text) >= 15) && (Convert.ToInt32(e.Row.Cells[2].Text) >= 17))

The syntax error comes from mismatching parentheses.

What's really wrong about the statement, is that if the value is >= 17, then it always is >= 15, so half of the code is totally superfluos.

if (Convert.ToInt32(e.Row.Cells[2].Text) >= 17)

TimeSpan ts = DateTime.Now.Subtract(DateTime.Parse("6/20/2007 11:21 AM"));
string strTimeDiff = ts.TotalHours.ToString();

"Back" button in Internet explorer does not change radiobutton selection.

I have a web form which has some radiobuttons in it. it looks like this:

asp:RadioButton ID="RadioButton1" runat="server" AutoPostBack="True" Checked="True" GroupName="aa" Text="r1"
asp:RadioButton ID="RadioButton2" runat="server" AutoPostBack="True" GroupName="aa" Text="r2"
asp:RadioButton ID="RadioButton3" runat="server" AutoPostBack="True" GroupName="aa" Text="r3"
asp:Label ID="Label1" runat="server"

in the vb file,

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
If Me.RadioButton1.Checked Then
Me.Label1.Text = "r1 is selected"
ElseIf Me.RadioButton2.Checked Then
Me.Label1.Text = "r2 is selected"
ElseIf Me.RadioButton3.Checked Then
Me.Label1.Text = "r3 is selected"
End If
End Sub

when the page is loaded, r1 is selected, then I click r2 and r3, then click BACK button in Internet explorer, the label text changed correctly, but not radiobutton selection. Can anybody explain it? and is there anyway to fix this?

thanks,

Enter key association with multiple textboxes

21-Jun-07 7:00

So let's say I have a Search textbox on a page and a login textbox on a page. When I hit the enter key on the keyboard I want it to fire the login button click event when the cursor is in the login textbox and fire the search button click event when the cursor is in the search textbox.

How does one handle that? I found some vague references in google about using javascript for this, but is there any C# asp.net native ways of doing this?

If js is the only way can someone post an example or a good url of where this is covered?

Thank you

u have to capture the key press event and you have to check the condition whether enter is pressed or not if pressed you have to dopostback on the control you want following the is the example to capture event.

in you aspx page under the for tag place your text box

<asp:textbox id="textBoxName" runat="server">

in page load event write the following code

If Not Me.IsPostBack() Then
textBoxName.Attributes.Add("onKeyDown", "javascript:checkEvent();")
End If

in your aspx page under the HEAD tag write the following javascript code

function checkEvent()
{
alert(window.event.keyCode);
if (window.event.keyCode==13)
{
__doPostBack("controlname",""); //please check the code i used to do like this only make sure view state of your control is true this is code i have used and it is working fone for me
}
}

Thanks

One solution here:

There is also one PARAM which we can set that allows SWF movies to share screen real estate with DIV. Can some one recall that?

Implement a website for subscribers to subscribe to get a report

Hi, my requirement is to give users access to pick what fields or columns (these columns may be in few different tables) to select and the criteria of the report. Once they pick that, I would need to generate a SQL and run the report. I am not sure what the best approach is for this in ASP.net. Can anybody please help me.

Thanks,
Madhu.

If you allow users to select the columns on different table, on what criteria you will link the tables ? I mean when writing query what will be the condition you use in where clause ?

Active user counting

Hello

I need to count how many users are active in the website. Do you have any idea on this. I did using application variable. On session_start event in global.asax I am incrementing the application variable count and session_end event I am decreasing the count. But problem is when user closes browser no event will be fired. So I am not able to reduce the application variable count. It will show the old result. Do you know any method to handle this efficiently.

I am changing the application variable like this

Application.Lock();
Application["count"] = Application["count"]  + 1;
Application.UnLock();

I know lock method stops modifying the variable value at same time. But what will happen if two users request at same time ? Will the second request wait's till application variable get unlocked ? Or that request will be skipped ??

This can be achived thru AJAX by doing the following

function saveSessionInfo()<br />
{<br />
    if (window.event.clientX < 0 && window.event.clientY < 0)<br />
    {<br />
         AJAXMethods.CallAJAXMethod1(callback_saveSessionInfo);<br />
    }<br />
}

call this method like

write your session handling end code here in this method

AJAXMethods.CallAJAXMethod1()<br />
{<br />
//do sth<br />
}

I don't think it is possible to get the user name if you have enabled anonymous access.
