This has reference to the article on ASPSnippets "Load data while Scrolling Page down with jQuery AJAX and ASP.Net".Records repeat after scrolling (e.g. Records 1-10 repeat after 10th record)
I verified that the pageIndex gets incrimented after the scroll by setting breakpoints at the point where the cmd.parameters value is being set(could not verify that further from hereafter though).
The stored procedure is able to fetch records e.g. 41-50 correcly affter excution in standalone mode by passing pageIndex=5 and pagesize=10 parameters etc. etc. etc.I also verified the code(line by line) from the site but, could not resolve the issue in more than a day's work.
select r.Name,c.Name,s.Name,(select count(p1.id)from profiles p1 where r.id=p1.religion and c.id=p1.caste and s.id=p1.subcaste and p1.Gender=1)as Male,(select count(p1.id)from profiles p1 where r.id=p1.religion and c.id=p1.caste and s.id=p1.subcaste and p1.Gender=2)as Female from religion r,profiles p,caste c,subcaste s where r.id=p.religion and c.id=p.caste and s.id=p.subcaste group by r.Name,c.Name,s.Name,r.id,c.id,s.id
I have a datagrid which pulls data from a single database table to display it. However, this database table also contains information on the thumbnail URL for each record, and I would like to display the thumbnails for each record in the 1st column of the datagrid.
At present I have added the following to my datagrid:
So I presume the main challenge now is to set the Thumbnail.ImageUrl property to the correct file path in the VB.NET code. But how do I do this for each record? I am using a function to retrieve data for the gridview, which is based on the following:
I have a Table (in SQL Server) that is being updated roughly every minute or so with new records being inserted from various sources. The number of records inserted in this duration varies from a few records up to dozens of new records. I am using an update panel to rebind my data every minute to keep the GridView current. Now that I have the data refreshing I am looking for a better solution than reloading the data every minute. how to best keep my GridView up to date? Here is what I would like to accomplish:
1. Load the GridView and refresh the contents every minute. (60 second intervals)
2. When the GridView is refreshed every minute I would like to append only the new records to the existing grid, rather than bringing back the entire result set with each round trip to the database.
3. I would like a visual cue to identify the rows that have been inserted into the GridView. If new rows were to flash/flicker with a background color (yellow) that would be ideal.
Am I even using the correct control for displaying real time data, or are their other options? I essentially am looking to find the preferred method of displaying data that is being updated in real time in a web application. I'm hoping there is a solution involving AJAX but I haven't been able to find much on The Google. I am open to changing anything and everything about my approach -- this is largely a learning exercise. For testing purposes I am currently using LinqDataSource in conjunction with a GridView in an UpdatePanel being refreshed by a Timer control every 60 seconds. Informational: I have also started playing with the [URL] in place of the Timer control. However, for the purposes of this example I would be content to achieve the desired behavior using native controls as I have described them above.
here I can find some info on how to display data from my MSSQL database in something like old style tables (table,<tr>,<td>) becouse I used to done it like this in classic asp but i had a formula for calculating where to put tr or td and it becomed very confused, not to mention displaying gruped records like 10 on each page...I tried gridview in VisualStudio but I can not find any info how to use sql in it so I think it can not help me becouse it is to much predefined and I do not know where I can change code for it like what data source to use, sql and other important thing
I am currently trying to figure out the best way to handle a data formatting issue. I have a stored procedure that pulls back basically all the data I need, but using a gridview doesn't really give me what I need.
For example...currently the gridview displays data like:
I have a problem displaying data in a Grid View control when set a row to visible = false when a certain condition is true.
For example, if a DataRowData value has a condition set to true (custom in table) I set the visible property to false, so the data row will not be visible at run time.
The problem is that I'm using paging (10 rows per page) and if 8 of those rows fall into the true condition that won't show the row, that grid view page will only show two rows of data in page 1. The worst scenario is that if I go to page 2 of the grid view and all the rows (10) fall into the true condition, that grid view page will not show any data at all.
How can I show 10 rows of data at all times in a gridview? In other words, I would like to just show the visible rows at all times.
I have a Transport Detaisl in DB , i want to dispay data on gridview with marquee scrolling up. Cabs are scheduled for drop every hour. So if drop is at 7pm i hav to dispaly on data of that hour from 6:30 to 7:15 later after 7:15 i have to display next hour data ie 8:00 pm drop data. I am able to get scrollin g data on gridview but how to schedlue it to scroll for such timings
In one of my application, I have around 2000 records which i am displaying in gridview with normal paging.
Now I want to change this paging facility and would like to show a "more" button at the footer(just like [URL] has). The moment user clicks it, the next set of data will be retreived. This will go on till all the records are fetched.
I have a gridview with 20 records and I have scroll bar to scroll down to view the records.I m displaying respective row data when click on the select button in grid view. The problem is whenever I select the
row, the gridview refreshes and scroll bar is going up. Ofcourse it is displaying correct data. but the gridview refreshes and scroll bar goes up.I want the selected row to be shown when I select that row.
I have a page with a datalist on it. The datalist shows numerous rows with various data in each column, each showin in a textbox. I'd like the user to be able to select or not select each row (displayed in datalist), and then to click a button which would place all of the data in selected rows into one big label so that it can be printed or emailed.
I'm in the process of developing a survey system. The tables / fields that are related to my question are:
My issues with this way were:
1) The Data Adaptors receive ALL the records from their correspondent tables. Not a good practice, I believe.
2) If, at some point, the survey had no categories, questions or choices under its child records, an error occurs when the page tries to build the Data Relation. With the work flow I had in mind for the system, this is bound to happen becuase all the Data entry pages (Add Category, Add Question, Add Choice) will be displaying the newly-created survey in a similar fashion (at which point, the survey will have no child records and so an error would occur)
