View 3 RepliesI have a web page which has about 11 gridviews.Hence the page takes bout 15 seconds to load.The grids are 1 below the other.They are populated at the page load.

The page should show gridview if its data is bound to it, not waiting for entire page gridviews to get populated.
Is there a way to jump over the last page of a listview whenever the pageloads

I have a shopping cart and when someone views an item and then returns to the gallery I want it to be on the page they left. Right now I set a session equal to the page and then try to look for it in the page load. My problem is that I select an item and then click back to gallery and it seems to take me to a random page.

View 6 RepliesI have a custom PagedDataSource created at page load.I have created two lin button "Next" and "Prev" to navigae the data source.I am using session to store the PDS and retrive it on each page load .I am incrementing CurrentPageIndex each time by 1 in the buttonNext click event and setting the value to the pds object.
What i am trying to do is, when the page loads, if page currently showing is last index, disable the "Next" button. The problem is, everytime I have to click "Next" one more time to make it disabled. It seems, the page does not recognize that it is the lastindex of the datasource when loading. When I click again one more time while in the last page , it is disabled.
