Hi,
I want to maintain the viewstate when i go from one Page to another.For eg: I have a Page with textboxs and Datagrid. When there is data in the first Page and when i go to another Page and come back , i want to see the data in the first Page. How to do? I have enabled Viewstate in the Page and for all controls, even then the data disappears.

View State is enabled for the same page. that is if post back to the same page then the values are retained . But if you go to another page you can create hidden fields in that page and then post that page to your page. then you can get the values by request.form(name of the hidden field).

for eg there is a textbox in form a . if you post to form b then create a hidden
field in form b and get its value in it. Then again post form b to form a then the values of th text box can be extracted by
textbox1.text=request.form("hidden field");

ViewState is a mechanism to remember control data during postbacks to the same page. It is not a state management tool for retaining data as you navigate a site, so it isn't going to be helpful to you in this context.

What you'll want to look into is programatically collecting that data that you'd like to maintain and saving it for use during the user's session. There really isn't a built in mechanism to handle this task, you will need to program for it. In general, this is referred to as "Session State".

A Google search[^] returns plenty of hits to sort through. I'd recommend taking a look at:

This[^] article over at Informit on ASP.NET session state beginnings

Hope that helps. Smile | :)

Datagrid Problem

Hi,
I have a datagrid and i am using datatable to bind it. There are 5 textboxs .Once i fill the textbox, i click a button ADD and the data from textboxs are added to datagrid. So i use datatable. Problem is when the Page is loaded, datagrid does not appear even if there is no data. Datagrid is visible only when we bind to datatable. Is it possible to display datagrid without any rows showing "NO Data" and display rows when we click ADD button.
hope U got my question.

Datagrid Headers are displayed only when we bind to datasource. Is it possible to display datagrid headers without setting the datasource.

Hi,
use datagrid headers and dont use autoGenerateColumns. Mention the columns yourself and then bind the grid to null at the pageload event(Ofcourse in if!isPostBack).

This will help you
Thanks,

Sushant Duggal.

I am using datatable for displaying in the grid, so i cant make autogenerate to false. Is there any other way to dynamically generate data in the Grid.
From the textboxes i am showing the data directly to Datagrid. Is there any way of displaying it.

Hi amaneet,

There is an option to be enabled before you start sending emails.
In the IIS , go to SMTP Server -- > right click select properties.Under the tab "access", the last option is for Relay. Tick the checkbox at the bottom and coose the option "All except the list below" from the two radio buttons,

I hope this works,
Thanks

You may wish to have a look at FreeTextBox[^]. It is a WYSIWYG editor for HTML that supports several themes, one of which is Office 2003. It is a generic text input control, however. You'll need to handle the mail portions on your own.

Hope that helps to get you started. Smile | :)

How big are the text fields that you are storing? ntext's length is 2^31 - 1 characters...

You must have a whopping server...

but anyway, i believe that is the largest data type field available in sql server. Can you maybe store the text in .txt files on a server and then store the link to them in the DB?

You can store 2Gb of unicode text (~1 billion characters) in an ntext column - do you really have files greater than 2Gb?
