Hi,
In one of my test ASP.NET 1.1 app I am trying to implement caching in one of the page (Default.aspx). I have implemented following directive
<%@ OutputCache Duration="600" VaryByParam="None" %> in my Default.aspx page. This page contains 1 Text Box & 1 Button. I type some stuff (lets say Hello World) in the textbox & redirect user to Default2.aspx page by clicking on the button.
In my Default2.aspx page I have an button which redirects user to Default.aspx page. When I am being redirected to Default.aspx page, Hello World is not being shown in Textbox.
Kindly let me know that is there anything that I need to implement extra in <%@ OutputCache Duration="600" VaryByParam="None" %> directive or some logic needs to be written in Default.aspx.vb code behind file?
Thanks in advance.
Regards,
Vipul Mehta

I don't find any issue with caching here. This looks like you are not familiar with caching concept. Say you have texbox and button on default.aspx. And user is typing something in textbox. Where you are storing that value ? Without storing that value you are redirecting to other page. If you come back to the original page, that value will be cleared since you are not loading it when page loads.
Caching is used to speed up the ASPX page performance. OutPutCaching caches the page output and updates the cache in the specified duration. To test caching you need to store the user entered value some where and load in page_load to textbox. You can see this value won't be updated immediately, it will be updated when ASP.NET updates page cache again.

Dear All,
I am making web application using Asp.net C#(Visual Studio2005).
I have checkboxlist(which is populated by all the master filed like category , subcategory ,customer , etc ). Now based on selection I generates web control label (to name the field) and dropdownlistbox (which is filled by code and its description).
My problem is all controls comes one after other. I would like label then dropdownlist in a single line. That custlabel and its dropdownlist comes in one line then next say categorylabel and its dropdownlistbox should align in next line and inbetween them one free line .
My code is
foreach (ListItem li in CheckBoxListmst.Items)
{
if (li.Selected == true)
{
//code added to fetch dropdownlist
setting = ConfigurationManager.ConnectionStrings["StyleSearchConnectionString"];
if (setting != null)
{
conn = new SqlConnection(setting.ConnectionString);
cmd = new SqlCommand("Search_display");
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("@cateid", SqlDbType.VarChar);
cmd.Parameters["@cateid"].Value = li.Text.ToString();
conn.Open();
cmd.Connection = conn;
try
{
// added controls
Label label = new Label();
DropDownList dropdownlist = new DropDownList();
label.ID = "label" + li.Text;
dropdownlist.ID = "dropdownlist" + li.Text;
label.Text = li.Text;
rdr = cmd.ExecuteReader();
while (rdr.Read())
{
ListItem ld = new ListItem();
ld.Text = rdr["disp"].ToString();
ld.Value = rdr["mstid"].ToString();
dropdownlist.Items.Add(ld);
}
PlaceHolder1.Controls.Add(label);
PlaceHolder1.Controls.Add(dropdownlist);
Response.Write("
");
//added controls end
}
catch (SqlException ex)
{
}
Please Guide me or atleast give some help full link.
thanks

I was wondering if there's an equivalent 'include'-type method for asp.net pages
(like php's include "incFolder/header.php" which includes the header on each page).
I have a master page, with a contentPlaceHolder (CPH). In the CPH, I load each page. However, there's a section of (html) code that I'd like to be able to include at certain places WITHIN the CPH (ie. the individual pages).
Can individual pages also reference some sort of cph's themselves? (this would be awesome).
Scenario:
- - - - - -
masterPage.master:
<br />
asp: contentplaceholder id=myCPH . . . . asp: contentplaceholder<br />
- - - - - - - - -
- - - - - - -
MyCPH:
<br />
Hello world this is my page<br />
<br />
HERE I want to include a generic block of code to be used in individual CPH's<br />
<br />
more myCPH stuff...blah blah blah...<br />
- - - - - - - - - - - - - - - - -
Any help much appreciated,

If it is only to be used in certain pages, then you could encapsulate it in a web user control and include that control where required.

hi Paddy,
Thanks but its only a bit of html (the page's footer) which I'd like to be easily update-able by changing the code in only one place rather than on every page...
Is this what a web user control achieves?
many thanks,
gerry

if you are saying that you want to select date of the month then use datepart funtion ie datepart (dd, filed from where date comes ).
hope this will solve your problem

its an sql fuction , you can use in query. you can test as
select datepart(dd,getdate())
hope this will clear your doubt.

if ur field in the table is of type date..
just do order by with that field
it will order by datewise...
by the way DATEPART function works like
DATEPART(month, GETDATE())
it will give u current month in numeric (7)

thanks , i am facing one more problem regarding the two dimensioal array.
to implement this i am using the following code.
Dim datearray(0, 1) As String
Dim counter As Integer = 0
While (objDR.Read)
datearray(counter, 0) = objDR.Item("wef").ToString
datearray(counter, 1) = objDR.Item("weeklyOff").ToString
counter += 1
ReDim Preserve datecounter(counter, 0)
ReDim Preserve datecounter(counter, 1)
End While
is there any problem in the code.
the problem i am facing is .. the array goes out of control.

Have you tried MSDN ?
I assume this is not production code, but a basic test of something ?

Hi, I need to create a folder on the server and upload the file to that new folder. The foldername is given by the user.
The problem is that it creates the foler, but don't upload the file and gives an exception. Here is the code:
string username = Membership.GetUser().UserName.ToString();<br />
string path = @"E:\asem\Visual Studio 2005\WebSites\Project\Files\" + username;<br />
try <br />
{<br />
if (Directory.Exists(path)) <br />
{<br />
}<br />
else<br />
{ <br />
DirectoryInfo di = Directory.CreateDirectory(path);<br />
} <br />
String filePath = path + "\\" + pdfUpload.FileName;<br />
pdfUpload.SaveAs(MapPath(filePath));<br />
Label1.Text = "File uploaded successfully";<br />
<br />
catch (Exception x) <br />
{<br />
Label1.Text = x.Message;<br />
} <br />
It gives me this exception:
x = {"'E:\\asem\\Visual Studio 2005\\WebSites\\Project\\Files\\erbol123\\bank_statment.jpg' is not a valid virtual path."}
thanx!

pdfUpload.SaveAs(MapPath(filePath))

x = {"Could not find a part of the path ...."}

I've got you thanx!!!
I created the folder first and then used Request.PhysicalApplicationPath
Thank you

Hi! 
Long time since I posted here...
I created a typed dataset using the wizard by adding a Dataset to the project.
I have a very variable menu(for a web page) structure that is stored in a database(SQL2K5X).
I need to be able to have the menu items stored as an xml file that the menu control will read from and I don't know how to do that. I tried several things but... I'm here 
So how do I dynamically manage my menu from a database?
Thank you for your help, sincerely,:->
