I have an ASPX page which contains grid,submit button and textbox. When some one enters text in text box and presses the submit button it will be added to database and will show in grid. All these are working fine. But problem started when I hit refresh button on browser. Suddenly already inserted data added once more. Any way to avoid this ?

printf("Navaneeth!!")

Actually what happens is when the page is getting posted back due to some event then it stores the event which posted back the data so when you clicks refresh then again the same event is getting fired that is why you are getting the same recorded again. I too haven't found a good solution for this problem. What you can do as a workaround is to reload the page again.

How can this ? if you are writing the code in Button click event then this should not happened. I think the data is getting added in datagrid only

Thanks and Regards

No, previously posted data will be there and it will repost the data when we press refresh button..

I don't have the code rite now with me., You can try the following scenario.

1. Create one text box, button,and one grid.
2. Write the following in buttons onclick event

button onclick()
{
    //Get textbox value and insert that to DB
    //get the result from db and bind the grid

}

You could see the newly added data on grid. Now press refresh. Browser will show one warning message. Press ok and check the result

printf("Navaneeth!!")

Hi
Just wondering if any one can help me on this simple question.

When developing in .NET 2.0 can components such as details view and gridview be used just as they would with SQL Server 2005.

I cannot see why they wouldnt as it is just an SQL Connection but I may be wrong - has any one done this/have any knowledge on this topic?

Thanks

Dan

Are you questioning why use something like the new sqlDataSource? I was say that the sqldatasource takes you a lot farther with a lot less code with a control like the gridview. Still if you have something simple that you don't need paging you don't need sorting, then yes it might be better to just use a sqlconnection with a sqlcommand doing a dataready to populate your gridview.

I want to Get the name of a user of my web site so I'm using this code but I'm getting errors:
string DomainUser = System.Security.Principal.WindowsIdentity.GetCurrent().Name.Replace("\\","/");
System.DirectoryServices.DirectoryEntry ADEntry = new System.DirectoryServices.DirectoryEntry("WinNT://"+DomainUser);
string Fullname = ADEntry.Properties("FullName").Value;

and the error is:

1:The type or namespace name 'DirectoryServices' does not exist in the class or namespace 'System' (are you missing an assembly reference?)
2:The type or namespace name 'ADEntry' could not be found (are you missing a using directive or an assembly reference?)

What could be the problem?
Thanks.

Hello friends..I have two textboxes on a form accepting url and submit button.when user clicks on submit button, it checks
1) whether the textboxes r empty
2) both textboxes must have same url
3) url must be between 2 to 25 chars..etc
if all these conditions r true then it redirects to another page..
I have taken server controls (textboxes and submit )..and try to write javascript on onclick of that button..but it gives error..like' ")" expected '. what is the easiest way to do that?

Why do you want to display two confirm window. Whatever validation you want you can do at one go and display the message later.
