I have a GridView control on a web page which shows around fifty pages (10 rows on each page). During navigation, from one page to another, the GridView slowly loads records. The page navigation is slow.
I tried putting this GridView control inside Ajax Control Toolkit's Modal Popup Extender. The page navigation is faster when GridView is inside Modal Popup Extender.
Is it just a coincidence or any other reason?
the Ajax Control Toolkit's Modal Popup Extender uses the Script Manager and Update Panel
by which the partial page is rendered
and on your plain page you have Script Manager and Update Panel so your page is rendered on pagination next and previous.
so if you want to make your grid view faster on plain page then use update panel which will reload partial page.

I have a gridview inside the content panel of a page that references a master page. I have paging enabled in the gridview and when I click on page 2 to view the second page the grid is displayed in another window that pops up. From the point onwards a click on next page shows the data in the popped up window.
How do I force the gridview to show the data in the same page?
I'm using ASP.NET 4.0
I have a master page. And a tab container is on the Master page. This master page have a menu. Now I want that Click on the Menu item, the WebForm/UserControl open in the tab panel in the tab container dynamically with closing button. Please help me.
The page will post-back normally , but if you use Ajax then it will look like clicking on the master page link loaded the tab content dynamically.
Can help more if you can post your code.
If you like to have a popup panel with close button (didn't understand your question properly) use model popup extender.
I have asp.net application and a TabContainer from AjaxControlToolkit on a form. There are 4 tabs, each containing UpdatePanel, hidden button and some custom .ascx (each with it's own javascript file). Buttons are triggers for panels to update the contents and they are triggered from the 'OnClientActiveTabChanged' event of the TabContainer.
This technique is described here and similiar here. It's pretty simple when looking at it.
The only problem I have is that the whole scenario works when used as a separate page but it doesn't seem to work when masterpage is around that page. Suddenly buttons act as full postback controls.
Do you have any idea what's the reason?
Assuming the buttons your referring to are on the master page, I think you'll want to register the master page buttons as update panel triggers.

I have a usercontrol on my page. The user control contains an ajax updatepanel with a listbox in it. There is also a PopupControlExtender that is tied to that panel so when the user clicks on something the popup shows. That is all working fine except when my page initially loads I briefly see all the listbox items and then they go away.
Got it:
style="display:none" on the updatepanel
I have an ajax control toolkit modal popup on my page and in that modal popup i have a gridview on which user select some item through checkbox on each row of gridview. Whenever user check or uncheck on checkbox my modal popup automatically hide. I have set autopost property of checkbox set to true becuase im perporfing some calculation on each checkchanged event. what may be the problem
Your page is posting back because of the autopostback="true" on the checkbox, thus hiding the modal popup.
Look up 'ASP.Net Page Lifecycle' for further understandinf. It is important to know how this works.
I'm sure you'd also like to know how to solve this.
You could:
Set AutoWireUp=false on the page, but then you'd have to wire all events on the page manually. Since you aren't familiar with the Page Lifecycle, I'm not sure how successful you'd be.
Use a javascript-only modal popup.
Perhaps an UpdatePanel can be used.
