The error means your code is poorly written. It's assuming a string is a date time, using Convert.ToDateTime or DateTime.Parse instead of DateTime.TryParse.
The actual issue could be the region setting of the server. It could even be that you're storing dates as strings in the DB, and the DB has them stored in one format and now the machine is trying to parse them in the other ( MM/DD or DD/MM )

Thanks for the reply!
However, didn't really help... since I'm only storing DateTime in the DB, and the regional settings were the same on both stations...
Plus, even if it is a code problem, I want to figure out what's the configuration difference that caused this problem. Since, as mentioned, it works fairly well on most stations.
Thanks again,

Hello friends,
I have userid on facebook. i want to access emailid using by userid. please tell me.
|
|
|
|

This is not even remotely an ASP.NET question. It's also insane. Why would facebook allow anyone to get members private email addresses ?

hi ppl
i just want a clarification.

You should be able to. ASP.NET can be coded in either VB.NET or C#. You'll have to add a reference to the .dll in your ASP.NET project.

Did you bother to try first ?
The answer is, it depends. If your dll exposes any sort of winforms functionality, it's not going to work with ASP.NET. otherwise, of course.

If this only the reason then you can just put the Gridview inside Div and use the Vertical Scroll of Div.

|

Thanks for replying, my GridView is in a Div with a Vertical Scroll,
but i think it looks better when the user doesnt need to Scroll a long moment to see all the GridView, and my Table have a lot of columns and the best way is (if their a way like this) to put the headers Horizontally then the user dont need to scroll a lot.

Yaa... I have already Guessed that ,you have already try it. But I don't think we have any other option.
Let me check, If I have found something I will surely update you !!!

|
|
|

ok thank you and i will be happy if you find something!
On the other hand, i am thinking if we can put an HTML code inside the (HeaderText:"")
Example: <asp:BoundField DataField="Name" HeaderText= <HTML Code <i>NAME</i> HTML>
and inside this HTML something like: do this Text Horizontaly. the Problem i am not very good in HTML and i am not sure if its exists something like that ( do Text Horizontaly) i know only we can change the Text to Bold like (<b></b>) or Italian like (<i></i>)...
??

Hi all,
I'm still fighting with getting multiple lines in a dynamic gridview. Searching around led me to think that if I can change the data during the rowcreated handler this just might work.
gv2.RowCreated += new GridViewRowEventHandler(gv2_RowCreated);
gv2.DataBind();
protected void gv2_RowCreated(object sender, GridViewRowEventArgs e)
{
for (int i = 0; i < 5; i++)
{
e.Row.Cells[i].Text.Replace(Environment.NewLine, "<br />");
}
}
Whenever I run the debugger, the new event handler line adds the handler, but never runs through the block of code. I'd imagine that during the DataBind, the rows are being created, so why isn't the system seeing this event?

From where you are executing this ? If you want to execute Event handler of a runtime created controls, you need to add this event handler before Page_Load()
|
|
|
|
|
Ah, maybe that's why! It's actually in the block of code that is being called from within the Page_Load().

Well, after moving it to the Page_PreLoad the event fires but apparently replacing the element.newline with the "
" didn't do the trick. Dang!

Why are you not using RowDataBound event?I think it'll fulfill you requirement.

No Brij, I Think, his problem is something different.
He Needs add event handler before page_load.

Hey Dude
Adding a eventhandler with every row means he wants to execute some statements on every row addiotion.My answer was the same can be done using RowdataBound function with ease.
