Hi Naishadh,
Thanks for the quick response.
But, to be very honest, I am new in the sharepoint environment.I know, how to export data to excel in asp.net,but not in sharepoint.If you can give me some details or some type of code, that will be great for me.
Thanks,
NIKI

Hi ,
as you know in asp.net 2.0 you can go to the menu select web site & then asp.net web site configuration like that you can configure tracing , debuging , security , roles ....
but in asp.net 1.1 (VS 2003) i didn't find that item in the menu neither (asp.net web site configuration)
can you tell me where can i find those items please ?
thank you very much
try to be good if you can't be the best

Hi there,
This menu item is only supported in VS 2005, in VS 2003 with the ASP.NET 1.1 you may look for a third party configuration tool like this one[^].

Hi thanks but do you mean i have to purchase this software to configure my application ? i think vs 2003 supports something else that allows doing the same stuff but i didn't find it
you said i have to look for a configuration tool , i sought for it but i found nothing,can you tell me where can i find that please ?
try to be good if you can't be the best

I have been experimenting with placing user controls (using Windows Forms controls) into an ASP.NET webpage - and am completely stuck. I can get a blank user control to work, but nothing beyond that. I have tried making a very basic test rig to isolate the problem, and have illustrated it below. For reference, this is using .NET 2 and Visual Studio 2005.
Here's what I did - the first few steps explain what worked, then what I did that broke it. If anybody can see the obvious thing I'm missing, I'd love to hear from you.
1. Create a new "Control Library" solution - call it "UserControlTestRig"
2. Modify the background color of the default control (UserControl1)
3. Compile, and test. The user control debug form pops up, and it works fine.
4. Add a new ASP.NET website to the solution
5. Copy the compiled DLL of the user control to the root dir of the website
6. Refresh the explorer in Visual Studio (to stop it complaining further on)
7. Add the following to the default.aspx page...
<object id="uc1"
classid="UserControlTestRig.dll#UserControlTestRig.UserControl1">
</object>
8. Run the webpage - it appears, as does the user control with it's background
color as set when we built it.
All is fine so far. Next I do the following, and have no idea why it breaks...
9. Edit UserControl1 - add a label control to it (from the standard windows form
controls)
10. Recompile UserControl1, and copy the DLL over to the web page.
11. Re-open the webpage, to see the usercontrol with the label...
*The control no longer works.*
What's more, once the control is broken, you can't then recompile without the label, re-copy, and run the webpage again...
If somebody can explain why this is happening I'd love to know.
The maddening thing is I have a fairly complex series of controls that this happened to this morning, and have spent all afternoon slowly going backwards until I got to this example - at which point I held my hands up and said "I'm going to ask on the internet"...
|
|
|
|
|
Getting somewhere... it's *something* to do with replacing the user control DLL.
If I re-compile the user control and replace the one in the web root, the webpage no longer shows the object.
If I destroy the website and make it again, it works once more - and (as you might predict) if I rebuild the user control again, the webpage no longer shows it...
Any ideas why ???
|
|
|
|
|
You may try to delete the Download cache with the command gacutil /cdl, then launch the web page again in a new browser.
|
|
|
|
|
I found *a* solution to it late last night.
The behaviour (recompiled user controls vanishing) only occurs in the Visual Studio 2005 web server. If you create an IIS website and put the compiled user control there, it works.
Therefore (at this time) I can only deduce that the problem - if it is a problem - exists with the mini webserver built into VS2005.
Hope this helps somebody else one day...

I click on one particular link which goes to a particlar aspx page. However, sometimes I just get an about:blank page. I don't think it's spyware as I've tried it on different PC's!

I have a datagrid with a link button column.
By clicking on this link button, i want a modal dialog to be opened
hoooowwwww?
|
|
|
|
|
You may need to do the following steps:
+ Create an event handler for the ItemDataBound event of the datagrid control.
+ Get reference to the link button.
+ Add the handler for the client event onclick of the linkbutton using the Attributes collection with the Add method, in the handler you'd call to show up the modal dialog box.
You can find the sample code from the site datagridgirl[^].

Hi all,
I'm currently trying to add (with a button) rows into tables (html table, asp table or gridView) .
I've tried : (asp:Table)
Private Sub AddRow()
Dim count As Integer = procTable.Rows.Count //never increment !!!
Dim myRow As New TableRow
Dim myCell As New TableCell
myCell.Text = "myCell"
myRow.Cells.Add(myCell)
'this is the asp:Table
procTable.Rows.AddAt(count, myRow)
End Sub
Had anyone an idea???
Thanks a lot

Hi ElpenS,
I work in C#, so i can give u an idea , what i think about the problem.
In C# when we create a new row , we create a new row for the table.
i.e.
TableRow tr = procTable.newRow();
And then at last we add the row to the table.
procTable.Rows.Add(tr);
I hope it works,
Thanks
Sushant Duggal.

Thanks to you for your reply,
Unfortunatly, it doesn't works in VB.net.
procTable.newRow is not defined.
Will wait on further messages...
Have a nice day

I can't take it any longer... Can someone pleaseeeee help me. I have included my code below. I have searched everything and read many articles but I still don't get it. So please no reaction in the sense; you must create your controls in page_load, you must recreate your controls in the onpageinit, preserve viewstate, etc. because I have seen all those matters, many many times. My guess is that I just miss a tiny bit...
On a webform I have a placeholder and in codebehind this placeholder is filled with 2 dropdownlists and two buttons. The two lists are filled with data from a dbase. When a user clicks one button an item is transfered from one list to the other, vice versa. What happens in code below is that I have to click a button twice to have an item move. Actually the first time when I click the button the item is transfered but the list wont refresh, while I regenerate the listboxes in my on page init (i tried the on postback as well). When I do a response.redirect to the same page it works fine but that shouldn't be the way to go.

What you miss is the control life cycle, or more exactly the order of the events. You bind the datasource to the ListBox in the Page_Load event, and update the data base in the button Click event, and basically the Page_Load happens before the postback event such as the button's Click event. So the list does not reflect the updated data until you click the button again or call redirect in order for the data binding code to re-run. Here, in the buton click event handler, after you update database you simply run the code to bind the datasource to the LixtBox again to refresh the control.

Hi all,
Can any body tell me how to restrict the user without seeing source code of the page by right clicking the mouse on the page and select view source or from view menu of the menu bar. Thanks in advance.
Thanks and Regards
Venkat

add some javascript:
<br />
page.onmenu = "javascript: return false;"<br />
(BTW - removed in the above replaced "onmenu" that I typed)
should prevent the cm functioning at all. As for disabling particular items, doubt it's possible - Guffa? Ista? Anyone hehe?
