Well, the obvious way is to write the code.
Do you have a specific use for AJAX, or did you just read about it in a trade journal and decide to use it ?
There are two ways to do this.
1 - download and install the ASP.NET AJAX library, and use controls from it. This is easy, but it won't teach you anything about AJAX
2 - buy a book and learn how to write AJAX code, and then write the code as needed. This is slower, but you have more control and will actually learn about AJAX along the way

I recommend reading the tutorials that came with it. It's way too broad a topic for me to cover in a forum reply, there are entire books written on that library

Hi Magesh!!
When you fill the textbox with student name automatically it will store in text property of the textbox at that time you can store Id in tag property of the textbox and u can retrieve the same as textbox.tag but i dont knw wether it works for autofill

Please don't cross post. And please don't ask dumb questions. You obviously know the answer to your question, it is indeed AJAX. You have no other options.

Wow - how do you hope your users will navigate that much data ? I hope you have viewstate turned off ?
My suggestion is to use a gridview and use paging so that users don't see that many records at once.

I'm not sure I understand the question. How can you show a 'loading' page ? By having your page do an AJAX callback that loads the data, and showing a floating DIV or something else that says 'loading'.

Can someone please help me?
I am developing a form in vb where I have a grid built on the fly based o a table. This grid is 2 columns, change and a description. I am using the first column "Change" as a linkbutton telling me what row I am editing. I use this logic in other places without problems, but I don't know why this will not work on this page. Here is my code:
Dim TableString, mVar As String
mVar = """"
TableString = ""
TableString = "<table border=" + "1" + " bordercolor = " + "000000" + " cellspacing = " + "0" + " cellpadding = " + "0" + " >"
Try
mSqlConn.Open()
sqlRdr = mSqlCmd.ExecuteReader
While sqlRdr.Read
Try
TableString = TableString + "<tr>"
Dim Typenum As LinkButton = New LinkButton()
TableString = TableString + "<td id = " + mVar + "Typenum" + sqlRdr("Typenum").ToString.Trim + mVar + " runat=" + mVar + "server" + mVar + "> <a href=" + mVar + "javascript:__doPostBack('Typenum" + sqlRdr("Typenum").ToString.Trim + "','')" + mVar + ">Change</a></td>"
TableString = TableString + "<td bgcolor = " + sqlRdr.Item("int_bguser").ToString.Trim + " forecolor = " + sqlRdr.Item("int_fguser").ToString.Trim + ">" + sqlRdr.Item("lngdesc").ToString.Trim + "</td>"
TableString = TableString + "</tr>"
Finally
End Try
End While
Finally
mSqlConn.Close()
End Try
TableString = TableString + "</table>"
lblType.Text = TableString
I am also sending the rendered code:
<table border=1 bordercolor = 000000 cellspacing = 0 cellpadding = 0 ><tr><td > <a id="typenum00" href="javascript:__doPostBack
('typenum00','')">Change Colors</a></td><td bgcolor = SpringGreen forecolor = Black>Full</td></tr></table>
I have no other references to java and I am a very basic programmer, so please keep the answer simple 
Any time we click on Change I get a error - object expected.
Any ideas?

Using the GridView-object makes working with data in a grid more easily.
There are tons of examples for you to make it like that.
ASPX:
<asp:gridview id="myGridView" runat="server" datakeynames="ID">
<colums> <asp:HyperLinkField DataTextField="TypeNum" HeaderText="TypeNum" />
<asp:boundfield datafield="int_bguser" headertest="BG user">
in Your ASPX.VB you create a Method which is called IN the page_load eventhandler.
In that created method you retreive your data from the database and DataBind it to the myGridView component.
Good Luck!

Hi, i'm in the process of learning ASP, so this is probably a really stupid question.
I'm trying to create a simular effect to the green menu bar the code project has above. On the left i would like the menu, and on the right, the login status.
I have tried a few things with div tags and styles but not got it working correctly. I notice above it is done with tables. Is that the only / best way to do it.
This is the snipet of code im working at the moment. The left and right styles just have float set to left and right (surprisingly).
<div id="mainMenu" >
<asp:SiteMapDataSource ID="siteMapDataSource" runat="server" ShowStartingNode="False" />
<asp:Menu ID="menu" runat="server" DataSourceID="siteMapDataSource" Orientation="Horizontal"
DisappearAfter="200" StaticEnableDefaultPopOutImage="False"
CssClass ="left">
</asp:Menu>
<div class="right">
<asp:LoginView ID="loginView" runat="server">
<LoggedInTemplate>
<asp:LoginName ID="loginName" runat="server" />
</LoggedInTemplate>
<AnonymousTemplate>
You are not logged in
</AnonymousTemplate>
</asp:LoginView>
|
<asp:LoginStatus ID="loginStatus" runat="server" />
</div>
</div>
<div id="content">
<asp:ContentPlaceHolder ID="mainContent" runat="server">
</asp:ContentPlaceHolder>
</div>
Thanks in advance for any help.

you can use Hidden field.

Why is it that I keep answering this same question lately ?
Create your two pages as controls, and show them both on the one page. Then viewstate will hold the data for you, your main page just has to move the data between the pages as it shows/hides them.

They don't relate to your computer, they relate to your ISP. Check Out look, they will be in there, or you wouldn't be able to check your mail.
