you don't have to. Another alternative is create web handler page (ashx page) put the functionality Abhijit provided in the ProcessRequest call it using ajax.

Yup Excelent... That is the best option, if you don't have the master page you can simply do it using handler other wise write the same in master page.

I am facing a unique problem (looks unique to me at least). I have a dropdown whose auto-postback is enabled. User can select a value from the dropdown to go to another page. But when the user comes back to original page by clicking the back button on the browser and clicks any button then on the post-back caused by the button, first the "SelectedIndexChanged" event handler of that dropdown is called then the "Click" event handler of this button is called. Hope I have explained the problem clearly.
Can anyone tell me what's going wrong and how to solve the issue?

Just put the code that you have written for redirect to different page of Dropdownlist SelectedIndexChanged.

I did the same but it is not working......looks like the browser is remembering the previous state of the page and so is causing the previous event to be raised in addition the present event..... I think I have to take help of javascript. Thank for the reply

 But I didn't suggested you to do any thing. I have just asked you to put those selected index change code.

Can you be a bit more elaborate. I did not understand what you want to suggest!

I suspect that what is happening is that when you go back the browser remembers the state of the controls when you originally left the page and sets them to those values. However, this time the value change for the drop down does not trigger a post back.
When you press the button the postback is triggered. The server then compares what is in the viewstate with what the controls now look like and raise events for any changes. Because it sees two changes (the drop down and the button click) those events are raised.
A possible route to solving the issue is to turn off the viewstate (which also means you won't get change events, although you will still get button click events) and detect the drop down change yourself rather than rely on ASP.NET.

Thanks for the reply Colin, I tried all possible options including disabling the viewstate as suggested by you but it all failed. I just managed to solve the issue with the help of javascript. Instead of sending the user to the next page via Response.Redirect on the index change of the dropdown, I am now doing the same with the help of simple javascript i.e. window.location.href. Thanks again for the reply, appreciate it!

What happens if the user has disabled javascript?
|
|
|
|
|
I our case this will not happen because whole site is javascript dependent. If it is disabled then nothing will work and moreover the site is for Intranet use and user of this site will not have the flexibility to turn the javascript setting of the browser on or off at will.
But this question still remains. What if the site were for general public on the Internet? In that case what could be the solution if even javascript could not solve it? Any idea!!

Is this happening only one one machine? Can you reproduce it on another machine.
Today, I spent 30 minutes on non-issue with my boss's machine. The browser had old cached copy and clearing the cache *fixed* the issue.

The problem is with Layout of you application. If you have some times then just go through with GRIDLayout and FromLayout Desing of ASP.NET.
You can use proper CSS to Fix Them.

Hi all,
How I can convert this code to a WebMethod in WebService?
This code is here:
Protected Sub Submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Submit.Click
Dim con As SqlConnection = New SqlConnection(WebConfigurationManager.ConnectionStrings("Articles").ConnectionString)
Dim cmd As SqlCommand = New SqlCommand("SELECT Title, Content FROM tblArticle", con)
con.Open()
Accordion1.DataSource = cmd.ExecuteReader
Accordion1.DataBind()
con.Close()
End Sub
I try to convert this code to webmethod But I couldn't convert it to a WebMethod for WebService and use it in Application.

How ? Adding [Web Methods] Attributes with a method does not convert it into a web service.
You can create a separate web service for that, or you can add webservice in your current web application, which will add a webservice.cs file in your app code and do the rest thing by calling the WS.

Hi all,
Is there a way that i can use inline and attachment at the same time in content-disposition for Response Headers?
i have code like this
HttpContext.Current.Response.AddHeader("Content-disposition", "inline; filename=__aaa.pdf");
I want to open the file first in the browser and then open the dialog box for download as well.
How can i do that?
I tried to AddHeader again after that line of code and replaced the "inline" with "attachment", but that didn't work.
Please help me.
Thanks alot!

So, what is you problem ? You want to create a Windows services which will regularly check your database and send the notification mail to the user ?
If yes, then what is the point to post this question in ASP.NET Forum.
You have to create a simple web service, which will call Some SP of of SQL server and retrieve the data from database.
By the way you can do all the thing only using SQL server 2005 also

hello,
i want to pass parameters in a POST mode from a .NET page to other page.
i heared about : Server.Transfer("xxx.asp",true);
can i have guidelines on how to use it ?
tnx in advance ,
avi
|
|
|
|
|
Server.Transfer("xxx.asp?paramname=paramvalue",true);
and your xxx.aspx page_load event read parameter value like
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
dim str as string=Request.QueryString("paramname")
End Sub
i thing is helpful

This is true and probably sufficient for many cases, but be aware you are changing from POST to GET and then have the limitations of the querystring, such as: maximum of 2083 characters in the URI(This is IE, not sure for FF/Opera/other), and of course there are potentially security risks if you are sending any sensitive data it will be shown and can be easily altered by the end user.
If you are trying a to re-post without relying on the querystring to a different page in your application there are probably workarounds (maybe by populating fields on an intermediate page, or manually building a response...then having one of them autopost to your ultimate target?) But I have never tried these before.
