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.

Cheers!!

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.

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>

Jamil

Session problem

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?

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

how to create a website page ???

20-Apr-10 0:14

This might be problem of slow internet connection. The load is heavy to your server.Do health monitoring of your webserver, you'll get some insight view also can use profiler to know where you can optimize.

Have a look for some performance and health monitoring technique in IIS 6.0
