Data Controls :: Large Number Of Columns In GridView
Mar 7, 2012
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 want datalist to show only 6-8items ,as these datalist is connected to datasource which has more than 20 items..
like in facebook,we have lots of friends but in friend box only 6 friends is shown and when we click that we go to next page which display all list of friends...
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 ?
I have a Gridview with 12 columns, Jan, Feb...Dec.

I want to insert a large amount( approx 7000 records) of data into a table, My scenarios is that i need to check whether the record already exists then it will not insert it. Currently i am using a stored procedure for this which gets called for each record.
IF EXISTS(SELECT 'True' FROM MYTABLE WHERE ID = @ID) BEGIN
--This means it exists, return it to ASP and tell us
SELECT 'This record already exists!' END ELSE BEGIN
--This means the record isn't in there already, let's go ahead and add it
SELECT 'Record Added' IF EXISTS(SELECT 'True' FROM [Aadil].[dbo].[SharePointSitesData] WHERE ID <> @ID)
I tried to find out about subject but with no success. The point is that in the beginning I've made many user controls. My site is too slow. I have not idea yet if it is because of user controls.
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.
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'm binding a gridview from a webservice with 30 columns and 10 rows, I need to print the same in a PORTRAIT, for that i decided to display columns as rows and
I'm trying to read a CSV file into a DataTable using OleDbConnection and OleDbDataAdapter. It works loading the DataTable, but only does 255 columns. The file has 362 columns.
I have an HTML markup which has HTML Table and Images in it. I am using iTextSharp API to convert the HTML markup to PDF. But, unfortunately the iTextSharp fails to export the HTML markup containing the Images & Table to PDF.
Error: The network path was not found.
using iTextSharp.text; using iTextSharp.text.pdf; using iTextSharp.text.html; using System.Data.SqlClient; using System.Text; using iTextSharp.text.html.simpleparser;

I know this error is due the Image Path. But, not able to resolve.
