Postback and asp:table

Maria

Hi

I have a asp:table that I want to hold the values between
postbacks. Hope some one knows how I can get that to work
in an easy way. The table is loaded in runtime with
different textboxes. When i press a button and runs some
server code the page becomes "quite empty"

Thanks in advance

question: are you using "<input type='text'>" or "<asp:textb ox id='txt1'
runat='server'> "

if i'm not mistaken, the asp textbox have viewstate enabled by default.
they should re-populate data on postbacks.

Hey,

Remember reading about this a while back but if you are adding controls
dynamically to your grid.... postback wont get 'em back. I suggest you read
up some tutorials on http://www.asp.net/Tutorials/quickstart.aspx

and check up on customer server controls.... framework.aspne t.webcontrols
newsgroup might be a good place to start as well...

Regards,
HD

meant custom server controls

a few lines from one of the articles at
http://www.dotnetjunkies.com/quickst...authoring.aspx

Maintaining State
Every Web Forms control has a ViewState property (inherited from Control)
that enables it to participate in ViewState management. The type of
ViewState is Sytem.Web.UI.St ateBag, which is a data structure equivalent to
a hashtable. A control can save data in ViewState as key/value pairs.
ViewState is persisted to a string variable by the ASP.NET page framework
and makes a round trip to the client as a hidden variable. Upon postback,
the page framework parses the input string from the hidden variable and
populates the ViewState property of each control in the control hierarchy of
a page. A control can restore its state (set properties and fields to their
values before postback) using the ViewState property. Control developers
should be aware that there is a performance overhead in sending data by
round trip to the client, and be judicious about what they save in
ViewState.

asp:Table DataBind method?

by: Marty McDonald | last post by:

I have <asp:Table... </asp:Table> on my webform. In codebehind, I populate a DataTable whose data should appear in the asp:Table. I created my own code to populate the asp:Table with the DataTable, then I discovered the asp:Table has a DataBind method. But the method takes no args and so I'm confused how to use it. Is there a link to see how DataBind works for asp:Table? Should I just use my own code anyway? Thanks... Here's my...

Editing an ASP:Table using Design View in Visual Studio

When editing an ASP Table, Visual Studio does not allow me to edit it in Design View. This makes it harder to add elements, because I must add every element either by using Design View to create the element outside of the table and then using cut & paste in HTML View to move it to the desired location, or by manually typing the code in using HTML View. The first technique sometimes does not automatically update the list of elements...

ASP:Table Problems

I am confused about the way in which asp:table objects work. When a control is within an asp table it generally appears to be in the scope of the tables parent control. E.g. if i have a page that consists of an asp table called MyTable containing a textbox control call MyTextBox then i can access MyTextBox directly from the PageLoad event handler without having to use MyTable.FindControl(MyTextBox).
