Other than the GridView that Christian has already recommended, I would also take a look at the Repeater Control[^].
It will repeat whatever HTML layout you want to use for each item in a list.

Hi all,
I'm pretty new to AJAX programming, and just started integrating the Microsoft Ajax toolkit etc. to VS2005. I followed the first sample and built a webpage containing a ScriptManager and an UpdatePanel, in which I've put a textbox and a button, and saw that AJAX worked fine to update this part of the page without the need to refresh the whole page.
But then I replaced my textbox / button controls with a self-made WebControl, which creates an HtmlTable in the CreateChildControls, containing rows and cells, and these cells contains linkbuttons with Events behind. This control was in the ContentTemplate of the UpdatePanel.
But when I click a linkbutton of my WebControl, the whole page gets postback and refreshed ... So my question is :
How can I build an AJAX enabled WebControl so it can behave like the standard textbox / button controls ? 
Do you guys know a good tutorial or book about that ?
Thanks !
Stéphane

It's worth mentioning that you do not need the AJAX toolkit, it's a framework designed to make AJAX happen automagically, but you get far greater control by writing your own code. If you choose to use the toolkit, make sure you always make clear you're using it, as your question is not an AJAX one, but a question on the MS AJAX toolkit.
A linkbutton in general creates a postback, I'm not sure how this relates back to textbox and button controls, or what exactly you're after ? you want the linkbuttons to use AJAX ?

Hi !
And thanks for answering me !
I'm sorry for my confusion between AJAX and MS AJAX ... Maybe they should have kept "Atlas" as the Framework name to avoid mistakes ...
In fact I'm not a Javascript fan, and never was ... The MS AJAX seemed to be a good solution for me, as it could give me the ability to use AJAX benefits without wondering about how it is implemented behind ...
My first try was to put in an UpdatePanel, a textbox and a button. In the eventhandler of the button, using C# code in the codebehind file, I put a statement like this :
<br />
protected void btnUpdate_Click(object sender, EventArgs e)<br />
{<br />
txtTest.Text = "This is a test";<br />
}<br />
At runtime, a click on the button generates a PostBack but the page doesn't move, only the textbox gets some text in it.
Then, to ensure a linkbutton can do that, I've added a link button in the same UpdatePanel. Here is the code :
<br />
protected void lkbAnotherTest_Click(object sender, EventArgs e)<br />
{<br />
txtTest.Text = "Link clicked";<br />
}<br />
The same : at runtime, the click on the linkbutton generates a postback but with the "AJAX behaviour", only the textbox got some text in it, the rest of the page didn't move.
But when I put a WebControl self made which is composed of a table with rows and cells themselves composed of many linkbuttons, at runtime, when I click on a linkbutton of my WebControl, the whole page gets refreshed ... I'm then wondering why ! And how I could get it work !

Hi,
I am working with Asp.net 2.0 (VB.NET)
I am getting a Exception :System.Threading.ThreadAbortException
at
Response.Redirect("Searched.aspx")
I have tried using below all code but I am getting the same exception
Response.Redirect("Searched.aspx", false);
Response.Redirect("Searched.aspx", true);
Response.Redirect("Searched.aspx");
Please help.

Sounds like you are trying to redirect at the wrong point in the page flow. What event are you trying to call Response.Redirect from?

I'm thinking that this isn't possible, but it can't hurt to ask. I'm trying to create a custom server control that takes a generic type, so for example:
public class MyControl<T> : WebControl { ... }
This works fine and I can create the control programmatically in the code behind file like so:
MyControl<Type> MC = new MyControl<Type>()<br />
MyForm.Controls.Add(MC);
I was wondering if there is any way to do that non-programmatically through the visual studio page designer. When I add it to the toolbox it shows up as: MyControl`1 which is the syntax used for a class with one type parameter, but when I try to drag it onto an aspx page it says: Element 'MyControl' is not a known element. If anyone knows how to do this I'd appreciate the info. Thanks.

You can consdier creating a stringbuilder object first and then add the HTML tags to it like as follows ones you have have it done send it to the browswer and it will render it for you.
StringBuilder sb = new StringBuilder();
sb.Append("<body");
sb.append("< body="">");

Wow, I'll have answered two questions with the same link within 5 minutes of each other. How can you get any better than that?
Take a look at the HTMLDocument[^] object.

Hi guys, I am counting Items on button click if total items are 5 then i want to display a popup or alert message through javascript. Currently i am calling in my button click event like this:
button.OnClientClick="javascript:alert('5 Items');";
The problem is I had to click twice to invoke this message. lets say the counter is 5, I clicked on messages appears, I clicked again then I do see this message. Can someone help me in it.
Thanks
|
|
|
|
|
you can try putting this under Button_Click event
Response.Write("javascript:alert('5 items');");
|
|
|
|
|
Thanks for answering. Acutally i have created those button inside an ajax updatepanel. That's y i couldn't use response.write method becuase it throws exception. Is there anyother way.
Thanks

Here's what I would do (note: ItemCount is a property I have wired to a Session value, you could easily make it a database driven value).
protected void Button1_Click(object sender, EventArgs e)
{
ItemCount += 1;
if (ItemCount == 4)
Button1.Attributes.Add("onClick", "alert('5 Items');");
else if (ItemCount == 5)
Button1.Attributes.Remove("onClick");
}
|
|
|
|

I tried but doesn't work. I only want to display the javascript alert box when there are 5 or more itmes . As i mentioned before
button1.attributes.add("onclick","javascript:alert('5 Items');");
display alert message when i click on twice. Please help me and am stuck dont' know how to solve this issuse.

The code I provided above will add the onClick event after you've clicked the button 4 times. So that means on the 5th click, the onClick event will cause the alert() to show. Then I remove the onClick event because you only wanted to show the alert() on the 5th time. I've tested this code locally and it works fine. Can you show us more of your code so we can see where the problem really is?

Hi I am new to Asp.Net as I have done in my previous programming ASP and also I did medium work on C# as well so in future i will be using C# with ASP.net.
the main query here is i created two textbox controls and one button when i want an action it goes to c# file. Do we have to write all these actions code in C# file or ASP.Net as well.
Also can anybody help me in starting a good tutorial which explains starting process for me. I dont want to go in to many details of using different controls for ASP.Net because that I will learn from time to time as i just want to do one or 2 application and then moving to ADO.Net and will try to create some good 3 tier architecture web applications using SQL Server 2005.
I will be very thankful to you.
Thanks
