Forms Data Controls :: Retrieve Data With Filtering And Paging?
Mar 18, 2011
I have a table with 500 rows and when I try to display them all, the response is really slow (local server). The situation gets even worse when I try to sort the results by a specific field. The filtering process is done in a store procedure by passing the parameters.
Well, here is my code:
[Code]....
I have 2 textboxes (start/end dates) and 2 listboxes which I use to filter my data. Here is my goal:
-make the response faster;
-including paging (does paging bring all the data or it fetches the data as I click on a specific page?)

I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.

I'd like to implement a custom paging template for my formview that displays numeric paging as well as next/previous buttons. The pre-defined templates only appear to have numeric first last as an option. Can anyone recommend a good article that covers this?

I have a gridview tied to a sqlDataSource. I want to filter it using FilterExpression of SqlDataSource. The controlParameter that I want to use is dropdownList SelectedItem.Value. This value is an integer. I am getting this exception: System.Data.EvaluateException:{"Cannot perform '=' operation on System.Int32 and System.String."}

I've got a GridView populated via a SqlDataSource whose Select command is controlled by a DropDownList. This is all working nicely:
How do I support the "All" user choice:
In other words, when the user selects "All" there are no aircraft names that match that so nothing is returned. Instead, I'd like the select statement to skip the WHERE clause in this case and just show everything. Do I need to create a second page for this case or is there a way to programmatically alter the SELECT command or some other way to accomplish this?

I have made an ASP.NET page with a ListView which binds to a Linq datasource which have inserting, updating and deleting enabled. All very trivial and well designed by MS. It all works very well so far.
Now I add a DropDown control to the page and binds the Linq datasource Where clause to the dropdown using the following code:
[Code]....
Now I can filter the listview based on the DropDown control. It works very well and I can still insert and delete rows in the ListView.
PROBLEM:
However when the DropDown control is used to filter the ListView rows I can no longer use the Editing functionality of the ListView. The row never goes into editing mode when the Edit button is clicked.
When the DropDown is not used for filtering - is in default state - editing works as expected.

This seems like a stupid, basic question, but I can't find how to do it (plus I've been doing MVC and haven't done in webforms in ages now) - I've got a DataList object that hooks into an SQLDataSource object, and this works fine. However I need to create a second DataList object for a slightly different set of criteria. Rather than creating a second SQLDataSource object and thus calling the DB twice, I would like to make my SQLDataSource object return a broader set of results (this is easy as I am searching on a column, then each DataList is further filtering on another column) and then further filter these results on each respective DataList - how do I do this?

I've been filtering my gridviews with the FilterExpression of the underlying ObjectDataSource etc. I am wondering how I can implement filtering on my GridViews if I just directly databind it to a datatable etc?

I need to filter data in a View using three dropdownlists that are populated independently of one another. The items in the second ddl are not based on the items in the first, etc. Each ddl is populated using its own sql statement. I want to be able to use each of these dropdownlists independently of the other two, but I want the data that is returned to be based on the values already in the other dropdownlists when I make a selection change.
For example: DDL1 is populated with Horsepower values from its own SQL statement.
DDL2 is populated with Gallons per Minute from its own SQL statement, unrelated to what is chosen in DDL1.
DDL3 is populated with Diameter values from its own SQL statement, unrelated to either of the other DDLs.
I want to be able to make a selection from any of the DDLs and filter data based on the selection, and whatever the current value is for the other two DDLs.
I'm coding in C# and I think I may need to create a delegate and an event to listen for when the SelectedIndexChanged event fires on any of the DDLs. This is slightly more complicated than anything I've coded up to this point, I'm a beginner, and I'm not even sure I'm aiming in the right direction for a solution.

I am trying to populate a gridview that returns only the logged in users' records. Specifically, I am getting a blank page when I load the page. To clarify, I get the blank page after successfully logging in to the ASP.Net Membership and do have data to return from the requested table.
I am reaching out to the online community after numerous failed attempts to research the solution and successfully return the desired results through trial and error variations.

I'm using a GridView with an ObejctDataSource. The data is provided by a business object and not a DB. It returns a list of people and each person belongs to a group. Now I need to filter data. For example, I need to return list of people in specific groups. How can I specify a list of groups to be able to filter the data ? Could I use SQL like syntax ? I understand the filter expression works only when data is returned as a datatable. But in my business object I maintain data as hashtables and return as List<PeopleInfo>. Do I need to return list as datatable instead ?

after hours of searching and testing (and found no luck), I came here to ask for your help again. I have a gridview and two dropdownlists. The first dropdownlist (DropDownList1) filters the gridview with Type of Customer. Here is the code on the aspx:

AppendDataBoundItems="True">
<asp:ListItem Value="1" Selected="True">A Type</asp:ListItem>

I'm having a HUGE problem with filtering!! I have a GridView1 with data from sql database (table called Requests) >> using asp:SqlDataSource Control.
and I have 2 columns (CV/ Transcript) which are Hyperlink columns..
I want to filter the data by:
1- GPA: for example view all data with GPA more than 3.55 and so on...
2- Credits: same as GPA (view all data with number of Credits more than 135 and so on...)
3- Dept. Name: it could be DropDownList and the user choose the department he wants to see results from.

I have a BLL that takes data from DB into datatables and for each datatable there are functions that transform them into Collections of the corresponding class.
When I put the data in a Collection into GridView through ObjectDataSource I don't have the option to click on the header of a column and get the data sorted. The headers are only clickable when DataTable is passed to the ObjectDataSource.
How can I get arround this problem without passing DataTables to the ODS?
