I so to really AJAX enable this I would need a few things to work out, but I don't want to bore you all with those details. I would have tried to do it all of this in my class library already if I could, but when I instantiate a new Trigger, and type "t." to see what options I have, they are only the 4 options that I would have with an variable of type object (Equals, ToString, etc). I cannot even find the "EnablePartialRendering" flag that you need to setup on these panels on the updatepanel obj. Many of these controls have very few if any extra methods/properties/events different from the "System.Web.UI.Control" that they all inherit from.
Am I doing something wrong?

hello.
is this an intellisense problem? if so, have you added the using directive to the source file?
I don't think that there is a problem with the intellisense, I mean, I have been coding for a few years now in .Net, using the intellisense to figure out how things work, without even really bothering with the documentation. It would seem that the Atlas is not to the point where it has the necessary XML markups to the source for the descriptions and what nots to kick in...
Basically, I am looking for examples, given an ASP.Net placeholder, to atlas enable it from the codebehind only, not from the designer... Make sense?
AB
hello again.
let me see if i got this correctly: you want to use the atlas server controls (ex.: UpdatePanel) from your source code files, right?
well, this should work, though i think that the intellisense info is not done yet (ie, you can see the methods/properties, but no info about them). so, your best option is to use .net reflector to see what it does (or, you can allways post your doubts here)
Yes, that is correct.
Have you seen any examples accessing the UpdatePanel from source code? The only examples I have found are in the ASPX Markup files, not the .ASPX.CS codebehind files...
The methods and properties I see are very limited, but as I see it, it would be done like:
Microsoft.Web.UI.ControlEventTrigger t = new Microsoft.Web.UI.ControlEventTrigger();
Microsoft.Web.UI.UpdatePanel up = new Microsoft.Web.UI.UpdatePanel();
up.Controls.Add(SomeLiteralControl);
t.ControlID(SomeButtonControl.ID);
t.EventName("Click");
Now, I can cause "SomeButtonControl" 's click event to change the Literals content and it will ajax that new content into the page?
AB
Ohh yeah, I also don't get the autocomplete for <atlas:UpdatePanel in my ASPX pages, any ideas on that?
AB
hello.
yep, adding triggers should be done like that ( though you still need to add the trigger to the collection maintained by the panel and this should be done until the init event of the page - btw, adding controls to the panel can't be done like that because you need a template).
what problems are you having with the updatepanel?
Hello,
I think I have the same problem. I thought I will start and try to change the example from
http://atlas.asp.net/docs/util/srcview.aspx?path=~/Server/samples/UpdatePanel.src
So the Panel2 is added to PlaceHolder on Page, but the panel doesn't update than.
Any ideas how it should be then, were to initiate the Panel.
For the moment my source code looks like that:
public
partialclassDefault6 : System.Web.UI.Page{
privateUpdatePanel Panel2;protectedint PostBackCount{
get{
return (int)(ViewState["PostBackCount"] ?? 0);}
set{
ViewState[
"PostBackCount"] =value;}
}
protectedoverridevoid OnInit(EventArgs e){
this.Init +=new System.EventHandler(this.Page_Init);this.Load +=new System.EventHandler(this.Page_Load);base.OnInit(e);}
publicvoid Page_Init(Object sender,EventArgs e){
Panel2 =
newUpdatePanel();Panel2.Mode =
UpdatePanelMode.Conditional;Panel2.ID =
"UPForm";Panel2.ContentTemplate =
newCTemplate(this);ControlEventTrigger pBtnClikEventTrigger =newControlEventTrigger();pBtnClikEventTrigger.ControlID =
"Panel3bButton";pBtnClikEventTrigger.EventName =
"Click";Panel2.Triggers.Add(pBtnClikEventTrigger);
phPanel2.Controls.Add(Panel2);
}
protectedvoid Page_Load(object sender,EventArgs e){
if (IsPostBack){
PostBackCount++;
}
}
protectedvoid Panel3aButton_Click(object sender,EventArgs e){
Panel2.Update();
}
publicclassCTemplate :ITemplate{
privateDefault6 m_pInnerControl;public CTemplate(Default6 pInnerControl){
m_pInnerControl = pInnerControl;
}
publicvoid InstantiateIn(System.Web.UI.Control container){
container.Controls.Add(
newLiteralControl(" [" + m_pInnerControl.PostBackCount +"] "));}
}
}
thanks a lot in advance

hello again.
sorry, i didn't look with attention to your code. btw, don't add the panel like that...OnInit is called ot handle the init event, so just call method that adds the panel instead of creating a delegate...i see that you set the trigger to a panel3dbutton...where is this button placed? note that if's inside an user control, you can't do that because you need the full id of the control.
hi,
Thanks for sam clues.
But i noticed that the posted code
upadtes the panel. I changed the line
container.Controls.Add(newLiteralControl(" [" + m_pInnerControl.PostBackCount +" " +DateTime.Now +"] "));
And the date is changed every button click. Only the m_pInnerControl.PostBackCount is always zero.
Anna
