    <p>There are many things You can do.</p> <pre><code>1.Cross Page Scripting </code></pre> <p>One of the problems faced by us in ASP.NET 1.x versions is the inability to transfer data between pages easily. Since ASP.NET 1.x pages postback to the same page by default, and you cannot do a post to another page (unless you remove the runat="server" and other messy things), accessing the controls in the previous page becomes very difficult unlike classic ASP where you have a action tag to specify the new page and you can use the Request.Form to access the previous page values.</p> <p>There is a more effective way of accessing the Controls in the previous page in ASP.NET 2.0. Its using the PreviousPage property of the Page.</p> <p>Say we have a page Default.aspx with a Textbox "Text1" and a Button "Button1".</p> <p>We can access the controls in Default.aspx from another page by the following steps:-</p> <p>A. Setting the PostBackUrl property of the Button to the New Page, as follows:-</p> <pre><code>&lt;asp:Button ID="button1" Runat=server Text="submit" PostBackUrl="~/NewPage.aspx" /&gt; </code></pre> <p>B. Then, in the NewPage.aspx.cs, you can access the TextBox control on Default.aspx as follows:-</p> <pre><code> public void page_load() { if(!IsPostBack) { TextBox tb = (TextBox)PreviousPage.FindControl("Text1"); Response.Write(tb.Text);} } </code></pre> <p>Note that a new TextBox tb is declared and typecasted using the PreviousPage and FindControl of the ID of the Control in the Previous Page. However, to retain the value across postbacks within the new page, its better to assign the text to a TextBox or Label in the NewPage.aspx such that its value is not lost across postbacks. The reason behind is that, the PreviousPage becomes invalid once you postback in the same page. </p> <pre><code>2.Sessions </code></pre> <p>You can refer the below link for help <a href="http://asp.net-tutorials.com/state/sessions/" rel="nofollow">http://asp.net-tutorials.com/state/sessions/</a> example Session["Value"]="Any Data"; You can access it in any page </p> <pre><code>3.Cookies </code></pre> <p>Creating a Cookie Object</p> <pre><code>HttpCookie _userInfoCookies = new HttpCookie("UserInfo"); </code></pre> <p>Setting values inside it</p> <pre><code>_userInfoCookies["UserName"] = "Abhijit"; _userInfoCookies["UserColor"] = "Red"; _userInfoCookies["Expire"] = "5 Days"; </code></pre> <p>//Adding cookies to current web response</p> <pre><code>Response.Cookies.Add(_userInfoCookies); </code></pre>

    2. COUse Viewstate and avoid the use of sessions. The viewstate does not store in the server, instead it is stored in the client side and maintains it state between server and client. The session on other hand stored on the server and creates the extra load on server if application is large.

    3. COI guess it depends on your requirement. if you only want to be displayed in next page, i guess Cross Page scripting works fine because it does not has any extra overhead. If you want the data to be accessible in whole website then you should for sessions or cookies. I guess Cross Page scripting should work fine for you.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
