i mean to say i am having the grid view just like shopping cart having drop down for product name and having the corresponding text boxes for price and quantity now i want to add new row having no selected item

i am maintaining the value in data table now i want to add new row above the selected row

the problem is i am able to get the values in text boxes below the new row but my selected value of drop is showing in the row which is new means to see the drop down corresponding to rows are not reversed

I downloaded the source code from the gridview girl.com site . If u are not aware of the article then i will provide the article too.

I suggest you buy a book and work through it so you know how to program instead of blindly copying code from various sites. Articles are great, but you should work through them so you understand the code.

We can't help you, except to say that you've used the keyword 'unicode' and it's not supported. For more info, we need to see the code.

}
private TableCell createcolumn()

return tc;
}

ds.SelectParameters.Add(pc);
ds.ID = "SqlDataSource2";
return ds;
}

}
protected void GridView1_PreRender(object sender, EventArgs e)

if (childtable != null)
Createrow(childtable, GridView1.SelectedIndex);
}
}
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{

}
}

and which line blows up ?

Have you thought to set a breakpoint, so you can see what *line* is blowing up ?

i did that too but every line is executing very well. At the end of lasat curly brace its giving error. i thought there is no error in the program. but i think the error i am getting is general error due to some settings. if anyone aware of this type of error then they may solve.

Hi..

Do you mean platform independent as far as hosting or viewing? Hosting, yes there are third party programs to host ASP on any major platform. Now viewing and using, it depends on what you mean, when you make a page, some browsers will view it differently but thats the nature of programming in itself. If you better explain what you mean by independent then I may be able to better explain.

Please don't spam the entire site. You've asked the same question in the last three forums I have looked at.

asp.net does not compile to an exe, you obviously have no idea what you're asking.

Of course not. No language offers that, not even C or C++.

Salam

Could i set out a master page in viewstate...Or Give me any suggession how to fix/static MasterPage....Because i don't want to postback Masterpage while loading child page....

I know whenever child page open its also compile masterpage...I handle menu right for using Session but not maitain Treeview state....

Means if user open tree 3rd level node and page is postback then again tree populated through Database but not maintain its state....not display 3 level node.

Thanks...

As I explained to you yesterday, that's not possible.

This is probably your problem, if you load the data from the database, then the viewstate will be lost, and it will reset itself.

Did you check the infragistic site, or just wait 24 hours to post the same question again, in the hope that the answer would change ?

hello

How to implement remember me next time feature for login control in asp.net 2.0. where user name and pwd stored in encrypted format for cookie. if anyone knows plz give some idea.
bye

Everything was working fine until I did something earlier today. And now my code can't see anything in the App_Code folder:

Compiler Error Message: CS0246: The type or namespace name 'alexegg' could not be found (are you missing a using directive or an assembly reference?)

The namespace alexegg is the code in the App_Code folder.

Here's what I've isolated to:

If I'm at my sites root, I have access to App_Code, e.g. www.appcodesucks.com/test.aspx

However, if I arbitrarily move my test page (test.aspx) down one directory to: www.appcodesucks.com/test/test.aspx, it doesn't work! I get the compiliation error.

This is the most annoying thing. Does anybody have any pointers?

You need to publish to the new place so all your reference locations get updated.

The only way to speed up a Macintosh computer is at 9.8 m/sec/sec.

Can you elaborate on what you mean? I don't quite understand...

/\ |_ E X E GG

You use Visual Studio to publish(save the application on the server) I assume. Just have it publish to the new directory. You said you copied the stuff to the new location yourself, you didn't manually change the hardcoded directory locations, if you use VS to publish it will do it for you.

The only way to speed up a Macintosh computer is at 9.8 m/sec/sec.

I am "publish" via FTP to godaddy. I actually deleted everything of the server, then recopied everything (ftp), and still no luck. Is this differnet then what you're saying?

Looks like this person experienced this too:

Did you use FTP to publish it the first time?

The only way to speed up a Macintosh computer is at 9.8 m/sec/sec.

The very very first time I've ever used this server did I use FTP? Hmm, I don't remember, probably. Why?
