Forms Data Controls :: Jerky Scrolling In IE8 Using Large Gridview?
Feb 28, 2011
ASP.NET 3.5,I'm upgrading a page that currently uses classic asp and xslt to display about 2000 readonly tabular records. Please leave aside the issue of whether this is a good idea or not.My asp.net replacement page uses a gridview to do the same thing.The scrolling in IE8 using this old code is very smooth and even. The scrolling using the asp.net page is horribly jerky. I can't figure out why - there doesn't appear to be much client side code running.Any clues welcome as this is a high traffic page that I want to look as good as possible.The same page also can't handle a row highlighter - same reason slow and jerky.
I put a GridView control in a Panel control so that the GridView's rows can be scrolled vertically. With selection of row enabled for a Button field, I am able to select any row with the selected row background color highlighted. Problem is when you scroll down to a row that is way pass the Panel height and select the row, after postback the GridView will render to show the top rows which are visible within the Panel height. So the selected row in it's background color cannot be seen.
I have used a GirdView to display data from database, data would be huge around 670 rows. And also I want to display all data together on single page.
Therefore I want to use virtual page scrolling. Means on Page load only 20 rows would be displayed, then when page would be scrolled next 20 rows would be displayed.....
I have a gridview that is currently showing 20 lines per page. Each line has several fields in it, three of which are dropdownlists. These dropdownlists are populated with a SQLDataSource and then the selected value is bound to one of the gridview datalements.
The problem I'm running into is that the page is very slow to load. I believe this is because of the large dropdownlists (and possibly because there are roughly 60 of them, each of which is executing a SQL query to populate the list of available values). The file size that is being transmitted over the web is just over 1.25MB in size, again from the large amounts of data in the dropdownlists.
Is anyone aware of a technique by which I could only execute the query from the SQLDataSources that populate the dropdownlists' available values once and then reuse the results of that query to populate the relevant dropdowns? Ideally I would do this on the client side so it would also limit the amount of text being transmitted to the client browser.
when i did not have too many controls on the gridview, it was displaying fine. but when i added more controls, it has become very slow and displays a large size for a second or so, and then comes to normal size.
I have 65 columns in the grid, if the columns are reduced to 20 then the speed when accessing from client is more or less similar to that accessing from web browser. Does it mean that all this performance issue is due to the data only ???
In my database m having 1000 record and I want to display 10 record on each page on gridview so every time it fetch 1000 record so while page loading it is quite time consuming ..
I'm trying to control the scrolling of a div containing a gridview using some js code I found at [URL] Intent is to stop the gridview in the div from scrolling to the top after the select in the gridview is operated. Prior to adding the ajax extentions the detail would display when the select image was operated. Now the grid appears ok but when the select is operated nothing happens - perhaps the nSelectedIndexChanging="DetailsView1_Show" code behind is no longer firing? Perhaps I am missusing the ajax extentions? Using VS 2010. My code is as below,
I have a listview and would like to scroll the ItemTemplatei instead of using paging. I need to freeze the header and InsertTemplate row, and works accross browsers. I've tried the following link:
[URL]
but am having problems getting it to work accross browsers I can get it to work in FF or IE6 but not both.
is there another control rhat's more suitable for this than the ListViiew?
After I changed Datalist1.SelectedIndex (and loading datas)page loads and loses curret scroll position in page.how can I autoscroll (focus) to selected Item of Dataliist after I changed Datalist1.SelectedIndex .so each time datalist Item Selection It goes to top of page.How can I revent this ? or keep position or scroll to selected Datalist item ?
Suppose I have a horizontally oriented ListView that always shows 4 items and also has a left & a right button: < A B C D >
Now, let's say I have a DataTable containing 20 entries, with indices ranging from 0 to 19.
When the page first loads, this is what'll be displayed: < 0 1 2 3 >
Assuming those buttons are regularly configured DataPage buttons then if I press the right one we'll get this: < 4 5 6 7 >
And if I press the right one again we'll get this: < 8 9 10 11 >
But suppose I'd like the left & right buttons to only scroll one at a time, so that pressing the right one at the start results in this: < 1 2 3 4 >
In such a case, is there a way to configure the DataPager to do this or should I instead introduce regular buttons and perhaps have them call a hidden DataPager?
Ok this is a bit weird. If I run this on my machine using IE everything looks fine. If I publish to my server and run using same machine and same browser my multiline textboxes show for a split second correctly then they scroll horizontally and get all messed up? Why are the scrolling horizontally and why do they look fine locally?
I have a user control that is common to the application. It searchs for lakhs of Items in one go from the db and I set the selected Items in a list in a session to pass on to the pages that use it. Hence making the application a tad slower. The gridview that contains the Items should have sorting, page indexing. What according to u,I should do to enhance the application's performance ?

Newbie to ASP.net. Programming in C#.I'm querying a SQL database and displaying the results in a gridview. The results can be many records so I need to provide the facility to scroll vertically and horizontally. To display the headers when scrolling I have implemented ( in my asp code) the headers in another table and the data is in another table. I see now I cannot align the column headers with the table data.Appreciate any help to fix this issue. ( What I need is a similar to the freeze function in excel where you can freeze the header while scrolling horizontally and vertically)If this method is not a good one to display headers with data please suggest another methodHere is my ASP code.
