Hey Abdul,
Changes done in the client-side using JavaScript will not save it ViewState. To ASP.NET, it doesn't know that you have changed something. To fix this, use a hiddenfield. When you hit the button, get the list of item into the hiddenfield with delimiters. Once the page is back, fill the list with the items with the hiddenfield value.
Only HiddenField can maintain states all the times.

hello all,
I want to fetch the static text written at html design page and then fetched data be entered into some variable at code-behind.
could anyone know the code to do so?

You might face problem of having some html into string variable. Please use the class "HttpUtility" and it method/property as required.
Thanks,

If content is inside a td/div/span/p then you can give the container control an Id and set its runat="server". At the server side you can access the control text using the InnerText or InnerHTML property.

I think you have problem for getting server side error when enter html code in textbox.
For the security reason asp.net does not allow this.
But you can enable it by making
<%@ Page validateRequest="false" %>

My webform has a link to download a sverver file: "http://Server/App/UpLoad/File1.xls".But when I have upload a new file to replace the old file(File1.xls),this link still download the old file.The stanger thing is when I have deleted "File1.xls",it also download the old file(where the old file from ?!).

Do you have screen to upload the files? If yes, check whether it is uploading to the right location or probably uploading?

You can give a try just checking whether you have anything 'hard coded' inside the application code.
Even deleting from source downloads the same file prompts me thinking same. 
Thanks,

Is it possible to use ASP.NET Control in MVC Patterns
|
|
|
|

Why not! You can use them... MVC is a pattern..There is a framework too that can be used to build ASP.NET application using it.

Can you please post just the webservice implementation instead of all? Right now, i don't see any webservice present... is there any? You need to have WebMethods in order to call webservice methods.
Kindly re-check and update the question with it.

|

Thank you so much for replying.
I have cleaned up the code to only include the web service code-behind and related ASP/XML code.
Thanks in advance for any insight you can provide.

Hello coders,
I have a web service which when called, should take the attachment that it got and use it in the response.
The webservice needs to create a csv file with 2 header values like type,location.
Then beneath that would be different rows which would look like this.
type,location
input,C:\input.csv // (I will be getting this C:\input.csv as an attachment)
output,C:\output.csv
imagepath,C:\
imagename,temp
width,800
height,800
I need to create this csv which i will be using and create an image based on this information.
Later i will need to send out the link of the images and the output file as an attachment.
I have found how to create a csv from the database but how do i hard-code it with the data i want?
So when the webservice is called, it will need to perform this. How can i do this???
Any help is appreciated. Thanks.

It's just a file, write it.

I have got the csv thing but my problem is mainly with getting the attachment (in the form of C:\output.csv) and after creating the image , i need to send back the image and csv file as attachments.
This webservice would be called and all these functionalities will take place but this service is running only when i press Invoke, how can i avoid this?

If I understand correctly, you want to run the service always right? If that is the case, you cannot do that using a Webservice. Go for Windows Services.
|
|
|
|
|
and how will get the attachments and send the attachments if it is a windows service?
|
|
|
|
|
but my project is actually a web service and not a windows service.
how can i do the attachments thing in a web service?
