You can use methods of Global.asax file
see help of Global.asax file in google
|
|
|
|
|
The Global.asax file is the central point for ASP.NET applications. It provides numerous events to handle various application-wide tasks such as user authentication, application start up, and dealing with user sessions.The Global.asax file, which is derived from the HttpApplication class, maintains a pool of HttpApplication objects, and assigns them to applications as needed. The Global.asax file contains the following event:
Application_Start : Fired when the first instance of the HttpApplication class is created. It allows you to create objects that are accessible by all HttpApplication instances.
you can use this event it to perform the actions you wanted.

Hey guys, I would display a calender when a user hovers over my dropdowlist box.
Is this possible?
I tried to use the SelectedIndexChanged and TextChanged events to make the calender
visible but it won't work. And yes autopostback is set to true.
Any ideas??
Thanks,
Morg

Instead of trying code behind, try javascript for mouseover event.
|
|
|
|
|
Thanks man, do you know what java script code you can use for that,
am not good with javascript..tried google and no help there.
Please help if you can.
Thanks

Without the code, its not possible to give some relevent answer
|
|
|
|
|
This is what I tried in my SelectIndexChanged event:
protected void DateFrom_SelectedIndexChanged(object sender, EventArgs e)
{
calDateFrom.Visible = true;
this.DateFrom.Text = calDateFrom.SelectedDate.ToString();
}
And it doesn't quiet work
|
|
|
|
|
It should be visible as per code.Try by default visible true and whether it is visible on the page or not..Also check might be it is getting false at some other point in application.

This event will fire when you change dropdownlist item and won't fire on mouse over. If you want it on mouse over then you can try javascript.

Thanks man, am not that good with javascript though, but still trying out google.
If you know how I can handle this please help me...
Thanks,

Hi Morg,
You can use javascript to hide/display your calendar please check below example:
<script type="text/javascript" language="javascript">
function ShowHideCalendar() {
var obj = document.getElementById('yourCalendarId');
if (obj.style.display == 'block') {
obj.style.display = 'none';
}
else {
obj.style.display = 'block';
}
}
</script>
<asp:DropDownList runat="server" ID="ddlMyDropDown" onmousover="ShowHideCalendar();">
<asp:ListItem Value="1">item 1</asp:ListItem>
<asp:ListItem Value="2">item 2</asp:ListItem>
</asp:DropDownList>

Hi,
I have developed a web application and created a virtual directory of that application(which is of Windows server 2003).After two weeks i found a problem.
ie when a user login(via virual directory link) i am taking his userid from database(sql 2005) with given userid and password and assigning that userid in session
ie Session["UserId"] = int.Parse(dstLogin.Tables[0].Rows[0]["UserId"].ToString());
then i am checking whether it is null or not
if (Session["UserId"] != null)
{
Response.Redirect("Home.aspx");
}
but in other pages when a user adding some data to database
i am not getting this UserId there.
ie while inserting userid of insering person will also store in database.while designing the table i made that field as "not null".
Not regularly but sometime users are getting an error like this
"Cannot insert userid as null". But most time it works fine
any solution or any idea to prevent this?
Known is a drop, unknown is an ocean

You problem is not very clear. Code is also looking fine .There must be some the data is not retrieved properly and not saved properly in session etc.. Have proper checks at the time saving and retrieving the data.. you'll get the actaul problem
