Unfortunately, this isn't very straightforward - js runs in the browser on the client, the C# code on the server. To call anything on the server you'd need to use AJAX to make a call back to the server.
I tend to do this with a callbacks page - straight apsx page, no markup, and a big ol switch statement in page load, which looks for a querystring param which indicates the method in the callbacks file I wanna call...
C# has already designed away most of the tedium of C++.

document.getElementbyID("IDName").Click()
or
FireEvent

No, Ko Ye Htut.
The question that he was asking is about calling the server-side function from client-side. It's true that document.getElementbyID("IDName").Click() can invote the server-side click event. but your code won't work if he wants to call the normal server-side function (e.g. public void MyMethod(){ })

You can't just fire the event to invote the server-side method from client-side script.. but it is possible to do with Ajax.

Hi,
you can try this.
Make Javascript function like this.
function GetClientScript()<br />
{<br />
var str= "My test";<br />
var test = '<%= GetFunction()%>';<br />
alert(test);<br />
}
Here GetFunction() is C# function. This function must return something else this cant work.
Now call this function onClientClick of any asp.net linkbutton or button.
And here you are..
Thanks,

Seem like you are confusing. The server-side script can be written in both class file (e.g. .cs or .vb) and aspx file. But if we want to write the server-side script in aspx file, you have to use <% %>.
So, the way that you showed is just writing the serverside code in aspx file. And it doesn't mean that you are calling the serverside function from client-side ( Javascript or vbscript or etc).
still confused? Okay. Let's say.. I want to call this function ( ServerSideFunction ) from Javascript when I click the button ( input button. not server-control). So, ServerSideFunction() should be invoked only when I click the button. (not on pageload).
How to do that?

I think so, anyway should be postback and call the Server Side function. Otherwise can not be called the server side function. AJAX is called partial postback and call the server function. So Main page is never refresh.
I know like this. If you know that ow to do with other way, please share it to me.
Thanks for best suggest.

As I said in this post[^], Ajax is the only solution for this problem. I was pointing out the mistake that you wrote in this post[^].
Thank you.

Hello,
I have a ASP.NET page and this page has Listboxes and some other controls like label, text boxes and a Hyperlink. When I click the Hyperlink I show up a Panel as a message box.
The issue is as soon as the Panel pops up, The list box behind the Panel is still Visible. But rest of the elements do not. Is there something we can do to sendback this list box

iam having a two input parameters in a stored procedures but from one time i want to send only one parameter ,the other paremeter is null in one case and the same way the other is also null in another case.how a null parameter is send to the sp.

myCommandObject.Parameters["@ParamName"].Value = DBNull.Value

in front end there are two text boxes one for reference no and other for employee id now the user can enter any of the value my query is how to write a stored procedure to check if the user enters refno then select statement is called for refno or if the user enter id then id select statemet has to call how it is possible to hceck which he entered in the
stored procedure
|
|
|
|
|
CREATE PROC FindEmployee
@RefNo VARCHAR(100) = NULL,
@EmpId INT = NULL
AS
IF @RefNo IS NOT NULL
SELECT * FROM Employees WHEERE RefNo = @RefNo
ELSE
SELECT * FROM Employees WHEERE EmpId = @EmpId
EXEC FindEmployee @RefNo = 'ABC123'<br />
EXEC FindEmployee @EmpId = 999
By specifying a default for each param in the SP (the = NULL bit) you do not have to pass that parameter to the stored procedure. Therefore by checking the default ( IS NOT NULL bit) you can determine which param was passed in. It should be obvious from the code above that if both are passed in it still uses @RefNo - this could be switched around to favour EmpId.

Hi, this might be a stupid question, but I don't know how to do it, and I need help...
I need to find out how to make one web-site controlled by more than one moderators.
I mean, for example, when one moderator is on-line and working on some profile to approve it (for example how moderator of forum work), another moderator should work on another profile. So, I don't know how to distribute the moderators job. And the number of moderators is growing.
thanks..

For something like this i'd probably use a local message queue on the server. This then sits there, allowing things to be popped off it, and new stuff added to the other end....
Do a goole for MSMQ (Microsoft Message Queueing)....

Hi,
I have created a Webusercontrol named sample.ascx.
I Have to dynamically load the usercontrol in my Webform.
The usercontrol has textbox control named Usernametxt,label control named UsernameLbl and a button control named Loginbtn
The following is the code i used in the pageload of my Webform,
protected void Page_Load(object sender, EventArgs e)
{
WebUserControl c;
c = LoadControl("WebUserControl.ascx") as WebUserControl;
if (c != null)
{
Controls.Add(c);
}
}
I get the following error:
Control 'ctl02_Usernametxt' of type 'TextBox' must be placed inside a form tag with runat=server.
Can ne body help me fixing the bug

Hi zari,
the textbox (and all other input controls) must be embedded into a form. Only a form can post the user input to the server. You need something like that.
<form id="form1" runat="server"><br />
<!-- place your controls here --><br />
</form>
I think, that you already have this form-Tag in your page. Just change the line "Controls.Add(c);" to
"Form.Controls.Add(c);".
