pls help restricting multiple logon to an application with single user account.
Here wht m doing is ,
m checking login details against a database.
if is a valid user then allowing to browse throuth the application.
my requirement is if one user is loged in and if someother user tries to login with same user account i need to restrict the second user saying "this login is already in use".
I can maintain a temp table for this , whenever a login is success i can update "isloged" field as true and we can set it false when user logs out. but how can we handle situations like
if a user logs in and closes bowser close button instead of log out.
if a user logs in and leaves doing nothing.
pls help in resolving this, if possible write a sample code for me.
thanks in advance.

Hi Surender,
Dilip Here again, sorry for late response, i was busy....
so your problem is as
[1] if a user logs in and closes bowser close button instead of log out.
==> if user is log in and close browser then you can call a javascript function on body's(HTML tag) unload event and in that function you can all a server side function which will perform logout procedure. for that you can use ICallback interface or you can use XMLHttpRequest.
[2] if a user logs in and leaves doing nothing
==> in such situations, your session will be expired. and when session expires, you can do coding of logout in session_end event.
OK, May my suggesions helpful to you.
Regards
Dilip Patel

What if JS is disabled?

You can write a SQL Job which checks the tables and update the flag which are expired. For this, you need to keep a timestamp which gives the last accessed time.

I have a gridview that has a column of textbox that users input something in textbox.I want to retrieve text of textboes after postback,so i wrote this code to store texts of textboxes in list and list in a session.but I don't know how to show them agian in textboxes.
my code to store text of textboxes:
protected void Button1_Click(object sender, EventArgs e)
{
List<string> qy = new List<string>();
foreach (GridViewRow gvr in GridView1.Rows)
{
TextBox q = (TextBox)gvr.FindControl("textbox5");
if (Session["quantity"] == null)
{
qy.Add(q.Text.Trim());
Session["quantity"] = qy;
}
else
{
((List<string>)Session["quantity"]).Add(q.Text.Trim());
}
}</string></string></string>
-----------------------------
and in pageloade i wrote this but I don't know how to continue it:
if(Session["quantity"]!=null)
{
List<string> temp=(List<string>)Session["quantity"];
foreach(GridViewRow gvr in GridView1.Rows)
{
TextBox tq=(TextBox)gvr.FindControl("textbox5");</string></string>
|

|
|
|
You can use the Grd Row Created Event
|
|
|
|
|
Just true the EnableViewState property of textvox or your grid.
|
|
|
|
|
the viewstates are true.I want to show text in textboxes agian after postback.

Hello,
I have a tag link with onclick() function(fnDelete). I am passing the string from the database.Eg: Here i want to pass the string(friend's).
since the string(friend's)is being with single quotes,the function "fndelete" is not called. And i am getting the script error as "Excepted ')'.So how can i pass the string(friend's) to that function?.
Can anybody help me please?..
Here is my code.
<asp:TemplateField>
<ItemTemplate>
<a id="del" style="color:Black; text-decoration:underline;" class="Itemlink" onclick="fnDelete('<%#DataBinder.Eval(Container,"DataItem.Name")%>')" runat="server">Delete</a>
</ItemTemplate> </asp:TemplateField>
function fnDelete(name)
{
alert(name);
}
|
|
|
|
|
use the replace method to add another single quote to the parameter
so instead of passing Friend's, you would pass Friend''s
|
|
|
|
|
No - if you're trying to write an apostrophe to a JavaScript function you need to escape it with an \
eg: friend's becomes friend\'s
|
|
|
|
|
Now it works when i Replace the single quotes
like
onclick="fnDelete('<%#DataBinder.Eval(Container,"DataItem.CatId")%>','<%#DataBinder.Eval(Container,"DataItem.Name").ToString().Replace("'", "\\'")%>')"
|
|
|
|
|
To correctly encode a string to put in a Javascript string literal, you have to escape both backslashes and apostrophes.
.Replace("\\", "\\\\").Replace("'", "\\'")
Of course, if you are absolutely sure that the string can never ever contain a backslash, you only need to escape the apostrophes.
Despite everything, the person most likely to be fooling you next is yourself.

Hi,
For the GridViews RowDeleting event, access the ID and remove it.
Here is the steps to follow. After successful deletion re-bind the list to the GridView control.
1. For the delete button, set CommandArgument as the ID.
<asp:Button ID="btnDelete" runat="server" CommandName="delete" CommandArgument='<%#Eval("product_id")%'> />
2. For the RowDeleting event.
protected void GridView1_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
Button btnDelete = (Button)GridView1.Rows[e.RowIndex].FindControl("btnDelete");
if (btnDelete != null)
{
int iProductID = Int32.Parse(btnDelete.CommandArgument);
if (Session["lstProduct"] != null)
{
List<Products> lstProducts = (List<Products> )Session["lstProduct"];
Products oProducts = lstProducts.Find(delegate(Products p) { return p.product_id == iProductID; });
if (oProducts != null)
{
//Give a message : record deleted successfully.
lstProducts.Remove(oProducts);
Session["lstProduct"] = lstProducts;
GridView1.DataSource = lstProducts;
GridView1.DataBind();
}
}
}
}
Hope it helps,
Thx,
Gayani

Products oProducts = lstProducts.Find(delegate(Products p)
what is delegate?I did't use product class.here is my code:
if (Session["basket"] == null)
{
List<string> pid = new List<string>();
pid.Add(productid.Trim());
Session["basket"] = pid;
}
else
{
((List<string>)Session["basket"]).Add(productid.Trim());
}
</string></string></string>
Button btnDelete = (Button)GridView1.Rows[e.RowIndex].FindControl("btnDelete");
I don't have RowIndex in my smart list.

Hi Gurus,
I have a tab container and under a tab panel I have datagrid .
When I dynamically populate the datagrid I find its height is more than the height of the tab panel / container. I do not get scrollbars for the tab panel. It gives me effect that my datagrid is overlapping my tab container.
How should I make datagrid remain inside the tab panel but still let it grow and in turn have scrollbars.
My code is
<ajaxToolkit:TabPanel ID="TabPanelResult" runat="server" HeaderText="TabPanel1" >
<HeaderTemplate>Result</HeaderTemplate>
<ContentTemplate>
<div align=center
<asp:datagrid id=dg_SearchResults runat="server" Width="262px" Font-Names="Verdana" Font-Size="7pt" PageSize="5" HorizontalAlign="Left" AutoGenerateColumns="False" AllowSorting="True" AllowCustomPaging="True" ForeColor="Black" CellPadding="2" BackColor="White" BorderWidth="1px" BorderStyle="Solid" BorderColor="#999999">
<FooterStyle Wrap="False" BackColor="#CCCCCC">
..
..
..
..
</TABLE>
<%--</asp:Panel>--%>
</div>
</ContentTemplate>
</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>
Please give me some feedback.
regards
vijay

Hi guys
I need to write the following sql query:
select * from table where field1 not in (select field2 from table2 where field3 like '%05/09/2008%' and sum (field3) < 1)
Basically I need to put a sum in the where statement, is it possible to do this?
thanks 
The answers posted by me are suggestions only and cannot be used in anyway against me.

Dear .netman,
first of all you can not use aggregate functions (like sum, avg) without using Group by clause.
and another thing also you can not use aggregate functions in where clause. you have to use Having clause with group by clause.
select * from table where field1 not in (select field2 from table2 where field3 like '%05/09/2008%' gruop by field2 having sum (field3) < 1)

Dilip Patel
