ADO.NET :: Retrieve Data From Database And Display To Gridview?
Dec 15, 2010
I have a application which connects to database. I have like 97 thousands data on the database. When I search something from front end and display those matching results on the browser, it crashes everytime (for huge number of data).
I'm using Dataset to retrieve data from database and display those matching results on Gridview(or repeater).
e.g. If I search 'abuse' it matches 65 thousands records and I can't retrieve and display those on browser, the browser crashes everytime.
I can search and display whole records without crashing the browser?
I have a page where I will insert all the data into the database. The page where I'm having problems is when I select an item from the checkboxlist it only displays one item. The data which is displayed is only the one that was inserted with one selected item from the checkboxlist. The following code is the page I'm using to try to retrieve the data from the database. I am trying to do is when a user selects the first, second, or third, or fourth item. The corresponding data appears in the gridview. In my current code, the record which has one item selected appears. If the user has more than one selected it does not appear. It comes up as empty. Is there a way I can do it?
I am creating a kind of feedback website which has a feedback form on it. Each question is answered choosing from a radio button group. the answers to each question are (very good, good, bad, failed). I need to be able to create a table on the webform that will display the number of answers to each questions. for example, if the question is "Rate the use of this software" i need to be able to put in table format say 20 people said "very good", 30 said "good" etc. at the moment i only have one table to display the questions and answers and a date that will be used to select the date's report. so all the information i need is coming from this table. all i need to do is how to say like "SELECT Count* Question where Review date = "user entered date" and answer = "very good" etc.
I would like to display the following information for each "Camera" (in the format below) on my web page in an HTML table. All the data is contained in one table in my database:
For Camera = Canon (e.g.):
Type (Text via asp:Label) Lens Size (Text via asp:Label) Storage (Text via asp:Label) Max. video resolution (Text via asp:Label) Max. photo resolution (Text via asp:Label) Weight (Text via asp:Label) Dimensions (Text via asp:Label) Sensor (Text via asp:Label)
...where (Text) is the value retrieved from the database for the given Camera. advise on the best way to retrieve this data? The only method I can think of (from my limited experience!) is to have a separate VB function for each value, to run separate SELECT queries for each field, and then to set the (Text via asp:Label)
value accordingly. I am already doing this for datagrid retrieves etc. For example:[Code]....
BUT... I know there must be a better method for the above requirement!

I want to get data from the database and display it in gridview. The gridview should be editable. Meaning the user can add, edit and delete items/rows in the gridview. Everytime the user adds/updates/deletes an item, the gridview is also updated. However, these changes will only be saved to the database once the Save button is clicked.

In the following code, I need to modify the Handler so that the records or results that display are based on a QueryString value.

I have tried to alter the code without much success.
