I have a .ascx page in when I redirect from another page, page_Oninit and Page_load events are occured and all controls loaded with initializecomponents().
But the page is not showing in the browser. Do you have any idea why this occur?
.ASCX is user control. When we add it into our page say 'Default.aspx' it becomes the part of that page but not whole page. So you can not use .ASCX as standalone. If you want to see it,you have to place it into some page and then only you can view it from browser.

Currently, in a dot net project, i have a master page & a child page. I have given various options, like textbox, combo box etc, on a master page with a submit button. Now i have a child page where i want to process the request sent by master page.
I have heard that retaincontrolstate is used like
private void retainControlState()
{
}
But currently i am not recieving the values from the masterpage onto the child page, not even the click event of the master page.
How can i make the click of master page button to send the request to the child page ?
You should:
Make sure you can access the controls on your master page from the page, e.g. make them public fields
In the Page_Init of your page, cast your the Master property to its proper type (or just use the MasterType directive - https://msdn.microsoft.com/en-us/library/ms228274(v=vs.100).aspx)
Then you can hook up the event handler in your page to the controls on your master page
ControlState has nothing to do with this.
Does it make sense to handle stuff on your master page in your content page's code-behind though? Why not simply do this in the Master page's code-behind?
I have an aspx page: Main.aspx which has several components that cause
a postback. In the page Main.aspx I also have an iframe which contains
a multi-page pdf file.
The problem I am facing is that whenever the user does an action which
causes a postback on the main page Main.aspx, the page posts back and
the pdf file in the iframe is reloaded. This is a problem becuase if
the user has rotated or magnified the page then that is lost.
Is there anyway that the content in the iframe is not refreshed?

I have a aspx web page. if i change something in the page and when it refreshes , does it load just the child page or even the master page?? What function one should use to refresh Master page as well!! I hope i am clear!!! Thanks guys!
The Page_Load of the child page will fire first followed by Page_Load of the masterpage. You may find this slightly counter intuitive. I know I did!
If you are relying on something in your master page being accessible from the code-behind in your child page you should reference it later eg in the Page_PreRender event of the child page.
Master page should always refresh. Not sure what you are experiencing?
I have a masterpage, having same old header, footer and content sections. I have different aspx pages bases on this masterpage. But each aspx contains a web user control.
For ex. MasterPage -> SiteMaster.master,
ASPX -> CreateBid.aspx,
Web Control -> CreateBid.ascx.
I have used validation controls within web controls showing validation summary within the same control.
The problem here is that, the page postbacks even if validation fails. The validation summary is also shown, but page is postbacked.
Could someone help me why this is happening?
Although the page is postbacked, no code is executed. For ex. If i am clicking on Submit button, nothing is submitted, i could see the validation summary or messagebox but the page is refreshed. If i am considering simple aspx without masterpage the validation works perfectly without page refresh.
Thanks for sharing your valuable time.
