Try this....

Add the following line to your web.config

I am using .NET 2.0 C#. How do I sort the data in a gridiew.
I constructed the data manually. Is there any sample or link?
thanks in advance. Much appreciated.

You need to sort it before binding to the grid. How to sort it depends on what structure it is in.

You can paas the data from one page to another page in multiple way. One simple way is to pass it through querystring. Here your data will be there with the URL and in the next page you can retrive the data from the querystring.

What you need to do is when you are redirecting to another page the you have to pass the value with the URL like this:
Response.Redirect("page2.aspx?ID=1234");
And in page2 you can access the value of ID like this:
string str = Request.QueryStering["ID"].ToString();
Best Regards,
Apurva Kaushal
|
|
|
|
|
Response.Redirect("page2.aspx?ID=1234");
What is the meaning of the ID=1234? The ID is declare by us? The coding is just simple like this? Do you have any reference site talk about this problem? Thanks..

here id is a variable in which you are storing the value. whatever value you will store in that you can access it in the next page. And also if you are sending the value through querystring then it will be visible to the user so important data should not be sent through querystring. alternatively you can use session for this purpose.

What you check is javascript files on the server. particularly this file "WebUIValidation" this is required for the validation controls.

i dont think that you can do any change on there server but you need to know about the folder and i not too sure about how you can check it on there server. Alternatively you can discuss this your senioy on how to handle this.

There is alot of method to go about it. And it is even better if you are using the current .NET 2.0 with the postbackurl property.
thanks in advance. Much appreciated.
|
|
|
|
|
But i'm using .Net 1.1 is there any other solution or sample code you can show to me? Thanks..

To pass data in-between forms, u have several options. To get a proper overview, search for state management in MSDN.
For immediate help:
string name = "Pei Sun";
Arraylist nickNames = new Arraylist(3);
nickNames.Add("PeSun");
DataSet ds = new DataSet();
//1. You can use HttpCookie which represents a cookie stored on the client's machine.
HttpCookie myData = new HttpCookie("CookieName");
myData.Expires.AddMinutes(5);
myData.Values.Add("name", name);
myData.Values.Add("nickNames", nickNames);
//add ds in the same way.
//Then add the cookie to the HttpSession.Cookies collection
HttpSession.Cookies.Add(myData);
//And thats it. You can redirect to your new page.
Live in fragments no longer. Only connect.

Hi Uma
try this
DateTime dtNow = DateTime.Now;<br />
string str24Hrs = dtNow.ToString("T",System.Globalization.CultureInfo.InvariantCulture);
regards
GV Ramana
|
|
|
|
|
DateTime.Now.ToString("MM/dd/yyyy HH:mm:ss");
Make sure the HH is in upper case, that makes it military time (24 hrs format)
