... I was able to create a nice templated server control.
However, what I noticed is that on some templated controls such as the ASP.Net UpdatePanel you dont need to use FindControl to find the actual control inside your template. UpdatePanel has a template (or similar) and this just allows dirrect access to your controls without using the FindControl method that I have to use on the templated control I have created.
How do I make my control like the update panel where no template is needed?
Title says it all. What is the difference between a DataSource and DataAdapter? I'm trying to decide if I should descend from IDataSource or IDataAdapter for code to be shared between Winforms and WebForms and I can't seem to figure out what the difference is other than slightly different ways to use them.

View 5 RepliesI have a legacy solution where all the DataSources are defined in the markup for all .aspx-pages. The problem I have with this is that the DataSource get instantiated several times since it is used in page, control... What I want is to have NInject to handle the instantiation of the DataSource so this doesn't happen. I have got that part to sort of work, but when the DataSource is defined in the code-behind instead of in the markup the Page property is not set on the DataSource, does anyone know why? A simple solution to this is to set the the Page property in a base class or something, but I do think that the property should be there and want to know why.
View 2 RepliesI have a simple datatable with 2 fields, one a primary key which I will call PK and other which I will call COL1. I have used the dataset designer to generate update/insert/delete methods on the tableadapter. On my development system two update methods are generated wit hthe follow signatures:
Update(PK as System.String, COL1 as System.Bool, Original_PK as System.String)
Update(COL1 as System.Bool, Original_PK as System.String)
On the production system, however, the latter signature is not generated. What is more preplexing is that prior to today, production operated similar to test. Obviously somethign changed, but I have been unable to identify what.
Unfortunately the method being used now is the latter. Now I can create my own method with a similar signature, but this problem isn't unique to this datatable/tableadapter. I am very hesitent to make thsi change throughout the application, and even more so in touching the several other applications which I fear may have similar issues (though those rely less on generated udpates).

View 2 RepliesI'm new to this community and got newbie question, briefly in data access in asp.net what is the difference between accessing dataset using typed Dataset and using data sources controls like SQL data source control ...? As I noticed that using data source controls is much easier, but it allows only one data access method i.e. only one query... am I right with that....
View 1 RepliesI am going to outline my setup then where i am failing
UpdatePanel1 - Contents : 3 textboxes and AddButton
UpdatePanel2 - Contents : 1 GridView and SubmitButton
AddButton adds new row to DataTable with data from textboxes, binds DataTable to GridView SubmitButton sends data to database. The Adding of a row works to add the row to the gridview, but it won't add a second or third and so on, only adds the 1. SubmitButton belives the DataTable that GridView is databound to is null and won't send anything to the database. How can i get the datatable to persist between the two update panels? Do i use Sessions as my storage location? Page

I have two update panels and one javascript control.
When the javascript button is clicked, it forces a partial postback on UpdatePanel2. UpdatePanel2 is populated with dynamically created buttons that have javascript effects (jquery) but when click can also induce a postback. My problem is that, when clicking on these dynamic buttons, the whole page does not do a partial post back but rather UpdatePanel2 itself does a partial postback and everything is gone.
However, what I want to do is be able to tie each of the dynamic buttons in UpdatePanel2 (After being dynamically created) and make them an asychnonous triggers to UpdatePanel1. So that when clicking on these dynamic buttons, ONLY UpdatePanel1 is doing a partial postback refresh. UpdatePanel2 stays put and remains the same.

I have a script inside an updatepanel. This script needs to be inside the updatepanel as it must be located in that spot.
Now when we click the "LinkButton" to update the updatepanel, the script will dissapear.
It seems that the script only is initiazed on the first Page_Load and Refresh of the page.
How can we keep it when pressing the "LinkButton"?

I am trying to build a web application using ajax.
but when I drag the ajax updatepanel on asp.net page it is not resizable,so how should i put other controls on it?
i am using a TabContainer and at each TabPanel i have embed an UpdatePanel in order to update each tab alone.
this is my code:
[Code]....
the problem is that it makes several seconds to update each tab (the same time for every tab) and i asume that this is happening because it updates all the TabContainer and not the selected Tab.
