By Default, TAB key works to transfer the control to the next cell. why not use them?

Thanks for your reply,
We can use the default tab key, but the client is interested to use the arrow keys/enter key for the mark entry, as the database to enter the marks is very big and using tab is not convenient to go to the specified cell.
i.e for eg: if the user enters the marks in the first cell in first row and after moving to 1st cell in 10th row, if he want to go back to first cell/second cell in first row he has to use the mouse/use shift+tab keys, instead he want to use up arrow/down arrow to move the position in the same location in the above/below row and so on.
kindly guide me in controlling of key navigations in a grid if u know.
Thanks and regards

1.username 2. userid .
i created a javascript menu & therez signout item. i want to clear the session when i click that & redirect to login page.. how can do it...

your subject line says 'remove sessions with Javascript'. For your kind information - Javascript runs on the Client and Session is a server Object.

You need to do the following in the server-end. call Session.Abandon() Method to cancel the session followed by Session.Clear() method to clear all the values from Session State.

use Javascript to AJAX off to the server, then Session.Abandon()....

Hi,
for what purpose you want to do this ?
If u want to bind with Gridview then you can add datasource.

This is like saying "I need to write a computer program, but I don't want to use any programming languages". Why do you need this ?

dear frnd,
You can assign values from database to list(arraylist,generic list) but you should use atleast datareader to fetch data from database.
They laugh at me; they think I’m different. I laugh at them, ‘coz they are all same!!

simple - you need to regularly poll for new messages and send them back down. AJAX is driven by the client, you still need the client to send a message in order to send something back

Seems ok. But if you are not using "EventArgs e" you pass null instead of "new EventArgs();".
and on the other hand i think it is better to initialize event handlers in OnInit instead of Page_Load..
What do you think guys?

|
|

what you told is exactly correct.bcoz i got error
object ref is not set to an instance of an object.but i am not getting how to handle it.i thought u hav a good knowledge on this topic.plz help me...(wats the code i need to write)

//in MyControl.ascx.cs
public event System.EventHandler Hello;
//in Button_click event
///I suggest:
if(this.Hello != null) this.Hello(this, null);
//in default.aspx.cs
protected MyControl MyControl1;
//in page_Load XX
///override OnInit
protected override void OnInit(EventArgs e)
{
base.OnInit(e);
this.MyControl.Hello +=new
EventHandler(MyControl_Hello);
}
//after Page_load
private void MyControl_Hello(object sender, EventArgs e)
{
//this is not a good way put a label and assing your value to it
Response.Write("welcome");
}
