Hi
I have a textbox which users enter search criteria into

When they hit a button a gridview will display any results that are found

however if no results are found I want to display a message

I have got

if (GridView4.Rows.Count < 1)
{
lbsearchcriteria.Text = "No results found";
}

but this if statement doesnt seem to work

any clues would be great

thanks

1) Have to turned off the Visibility to false ?
2) If you are using Ajax and update panel ensure both search button , grid and label are in the same update panel.

Thanks

well its just not reading the if statement because i have this:

if (GridView4.Rows.Count < 1)
{
lbsearchcriteria.Text = "No results found";
}
else if (GridView4.Rows.Count > 0)
{
do something
}

but it performs the second if statement even if no rows are displayed
is the if statement incorrect?
thanks

No..But why you require another if after else

if (GridView4.Rows.Count < 1)
{
lbsearchcriteria.Text = "No results found";
}
else
{
do something
}
This is same right ?.
May be you can try this ?(Dont ask me the thought behind it Wink | ;)

)

if (GridView4.Rows.Count > 0)
{
do something
}
else
{
lbsearchcriteria.Text = "No results found";
}

Thanks

Hi All,

My .net application automatically creates .tmp files, and are written to c:\winnt\temp folder. Now when the users access the application, they also shd be having the permission to c:\winnt\temp folder of server to allw writing .tmp files, or else will get error as Compiler Error Message: CVT1108: cannot open C:\WINNT\TEMP\RES4F42.tmp for writing. After manually giving authenticated users 'Write' Permission to C:\WINNT\TEMP\, Application runs perfectly.

This is only a temp soln, after sometime the the c:\winnt\temp folder will not allow authenticated users to write (the write permission would have been unchecked automatically).

Is it possible to redirect .tmp files to different folder other than c:\winnt\temp

Any suggestions please..

.
.
.

[assembly: FileIOPermission(SecurityAction.RequestMinimum,Unrestricted=true)]
class test
{
}

Hi,

We can't find out which pages writes to c:\winnt\temp folder, in that case how can I include the above code application level.

Thanks,
Giri

In that case you will have to use CasPol utility that comes with .net Frame work to provide permissions to your assembly.

How does it 'automatically' create temp files. Can you not just change this code to output to a different directory?

I believe when .net applications are running, creates .tmp files automatically and by default they are written to C:\WINNT\Temp folder. Even I tried for IIS options to redirect the .tmp files to different folder, no use Frown | :(

I've worked with a number of asp.net applications and never encountered this as a problem. You might want to check how your framework was installed and also if you have a draconian security policy, you need to get an admin to sort something out to permit your application to work.

how to implement such functionality in asp.net

A timer is not a control, it's a class, it's just offered in the forms designer for people who are incapable of writing code and who need designers to create forms.

I recommend you buy a book on ASP.NET and work through it. As your ASP.NET code runs on the server, it's obvious you can't impliment a timer in code behind. You need to use javascript for that, because that's the language that runs on the client. You can force a postback on your timer, do things in the UI, or make an AJAX call.

it depends how you want your timer to work

I have a similar method to a timer working at the moment

I have a page which 5 minutes after a user accesses it, it changes state, i.e. automatcially refreshes and something happens

explain more about how you want a timer to work

Yes, sure, so you can do that with javascript, like I said ( I said, javascript can do a postback )

You may need to use JavaScript and try setTimeout function.

*sigh* but who needs an 'AJAX' control to set a javascript timeout ? Really ?
