I have a link button inside a repeater. How would I directly call the serverside (ItemCommand) method during postback. I want to skip the page_load. The wierd thing happening is, if I put (!Postback) it doesn't execute other methods on postback but it does if I don't set the !postback condition. I have repeater inside a updatepanel in UserControl.

I have actually resolved my problem but I want to understand why. The scenario I have is an input for logging in on my Default.aspx page. When the user logs in the page refreshes and the login box changes to display a logout box using:
loginBox.visible = false
logoutBox.visible = true
My question is about the positioning of this code. I had my code validate the users input when the btnLogin is clicked. I then had those two lines above under PageLoad but this did not work. The user would log in but would have to refresh the page to update the boxes. Instead I had to place those two lines of code in the btnLogin Clicked area, at the same time as the user is validated.
It was always my understanding that when something on the page is clicked/activated the entire page is reloaded, but this appears not to be the case otherwise the PageLoad area should have worked.
This is my first web page ever and I can't seem to find the correct way to get the selected index from a dropdown list. I don't need the selected index until the user presses the submit button. I've been testing everything I've found on the subject, but nothing is working.
I don't want the drop-down box to reset when the selection is made, which is what happens if I use postback=true or any selected index changed events. And, I still get an index of 0.
When I test, the selected index is always zero.
This runs on page load:

I searched the forum for several days now , but can't find an answer to my problem.
I have 4 Ajax Cascading DropDown named,
ddlCatalogueName > ddlMainGroup > ddlSubGroup > ddlPageNumbers ,
I am passing the values obtained from ddlSubGroup and ddlPageNumbers to a datasource as parameter (Actually to a pageddata ) , on which i create a DataList.
The page is working fine actually but the problem is like the following,</p>
Considering that all dropdown are selected as following :
When i change ddlSubGroup to another one , ddlPageNumbers is populated depending on the number of items divided by 20 ( The datalist is paged by 20 items per time)
then i change the ddlSubGroup(RUBBER PARTS in this example for example to BodyParts , so the dropdown values becomes like :
[code]....
At this point Body PARTS also has page numbers like 1,2,3,4 etc but, it still remains as 2 , however i need the page number to reset back to 1.
Is there any way to do this , and where should i place the code exactly ( which event ) ?
