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

Hi..
I have a UserControl named MyControl.I have placed a Button on this UserControl.I placed this UserControl on my webForm named Default.aspx.My requirement is to raise CustomEvent when i click the Button.
This is the code i tried.....
//in MyControl.ascx.cs
public event System.EventHandler Hello;
//in Button_click event
this.Hello(this, new EventArgs());
//in default.aspx.cs
protected MyControl MyControl1;
//in page_Load
this.MyControl.Hello +=new
EventHandler(MyControl_Hello);
//after Page_load
private void MyControl_Hello(object sender, EventArgs e)
{
Response.Write("welcome");
}
----------------------------------------------------------------------------
i am able to print "welcome" in 1.1 version.Above code is working fine.but in 2.o its not working.i need this in 2.0.plz anyone help me.....................

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");
}

Response.Write( "<script language='JavaScript'>" +
" function showAchPendingMsg() { " +
" var pendingConfirmation = window.confirm('PG');" +
" if (pendingConfirmation == true) { ShowDetail()"+
" } else { DoShow()"+
" " +
" } " +
" }" +
" showAchPendingMsg();" +
" function DoShow() { alert('else');}"+
" function ShowDetail() { alert('if');}"+
"<" + "/" + "script>");

RegisterClientScriptBlock is better, and you didn't show him how to hook the call into his click event, either.

Is this the code wot u were talking about ? If yes will u plz lemme know why it is better?
string scriptString =( "" +
" function showAchPendingMsg() { " +
" var pendingConfirmation = window.confirm('PG');" +
" if (pendingConfirmation == true) { ShowDetail()"+
" } else { DoShow()"+
" " +
" } " +
" }" +
" showAchPendingMsg();" +
" function DoShow() { alert('else');}"+
" function ShowDetail() { alert('if');}"+
"<" + "/" + "script>");
string scriptName = "Confirm";
if(!Page.IsClientScriptBlockRegistered(scriptName);)
{
Page.RegisterClientScriptBlock(scriptName,scriptString);
}

He is telling instead of using Response.Write to send JS script, use RegisterClientScript which is in page object.
|
|
|
|

Yeah I understood.. But now I just want to know how it is better.. what is the utility of it.

What did you exactly tried to do with the Response.Write method? Let me say that clearly - You tried to Register blocks of client-side script containing functions. Microsoft has provide a method very specific to perform this particular task 'RegisterClientScriptBlock'.
Response.write Method is meant for writting a specified string to the current HTTP output. The specified string can be a Dynamically Build Javascript Code. But it's well suitable for a Javascript Alert message when we try to write Javascript code on the client using Response.Write(), Not for Registering blocks of client-side script containing functions. There are many ways to solve a problem. The question is Are we doing it the right way, the best way?

This is not the exact difference. Response.Write() places the string (in this case dynamic JS code) supplied on the top of the page, that is outside HTML tag. But using the specified methods to emit client script ensures that it is inside the DOM. You can use either RegisterClientScriptBlock() or RegisterStartupScript() for injecting JS code to the page.
More over, RegisterStartupScript() executes before the page's OnLoad() event fires.
