i am using gridview control and a linqdatasource and its all working fine and i have added the functionlity of searchingBySubject and i added WhereParameters and than binding my gridview (see the code below) but somehow its not returning any rows and i see i have number of rows based on what i am searching.

i have a grdidview control on the .aspx page and i am trying to connect dynamically from code behind and bind the gridview but somehow it throwing me an error... what is wrong with this code?
LinqDataSource LDS_POReport = new LinqDataSource();
LDS_POReport.ContextTypeName = "DataContextDataContext";
LDS_POReport.Selecting += new EventHandler<LinqDataSourceSelectEventArgs>(LinqDataSourcePO_Selecting);
this.gvReport.DataSource = "LDS_POReport";
//this.gvReport.DataBind();
Update:
after i update the code to this.gvReport.DataSource = LDS_POReport;
it works fine but when i try to sort i get this error:
The GridView 'gvReport' fired event Sorting which wasn't handled.
i added this but no effect.
LDS_POReport.AutoPage = true;
LDS_POReport.AutoSort = true;

I am writing an ASP.Net web application. I have listview, it's datasource is a LinqDataSource. In my database, I have a staff table and I am trying filter for records by their team using a dropdownlist. This works fine, until I select "All" in the dropdownlist. It returns all staff except for the ones where the teamID is null. How can I return the records where teamID is null?
This is my code:
<asp:ListView ID="ListView1" runat="server" DataSourceID="ldsStaff" DataKeyNames="staffID">
<LayoutTemplate>
<table>
<tr>
<th>Name</th>
<th>Team</th>
</tr>
<tr>
<td> </td>
<td><asp:DropDownList ID="ddlTeamFilter" runat="server" DataSourceID="ldsTeams" DataTextField="Team" DataValueField="TeamID" AppendDataBoundItems="true" AutoPostBack="true">

in other words, reading the content (records that lies within) of a LinqDataSource object programatically (i.e. similar to what the GridView class does internally when binding to a LinqDataSource object).

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 have a LinqDataSource and a GridView displaying a table. Columns of type xml don't show up. I'd like them to show up something like they do in Sql Server query outputs, with a link to display the clickable xml, though there may be another approach i'm not considering (maybe a styled display of the xml data, etc.). Two things i'd like to know how to do
First, get the xml converted to a string, and display it in the table. Maybe the first 30 chars.
Finally, style the xml into something useful, like a clickable link to display the full xml, or a sub-table, or a styled string.
So the following works, and displays a nice table, with edit and delete links. But Xml fields are missing. How would you go about adding support for the Xml fields?

I've a gridview bound to linqdatasource1 and a details bound to linqdatasource2 (for searching).
When I update the data on detailsview, my gridview is not updating. I've tried handling various gridview events and databinding the gridview in code but it doesn't seem to work.

I have two tables:
Orders
OrderProducts - An order can have 1 to many orderProducts records associated with it.
What I am trying to do (unsuccessfully) is to implement a GridView search using a LinqDataSource wherein the search returns Order results where any of the OrderProduct.Manufacturer columns contain a search query. I was hoping the following would work, however it seems lambda expressions do not work within a Where clause of a LinqDataSource (in VB):
<asp:LinqDataSource ID="dsOrders" runat="server" ContextTypeName="myDataContext" TableName="orders"
Where="orderProducts.Any(Function(op) op.Manufacturer.Contains(@searchTerm))">
<WhereParameters>
<asp:ControlParameter Name="searchTerm" ControlID="txtSearchTerm" DefaultValue="" />
</WhereParameters>
</asp:LinqDataSource>
In C# it would look like:
<asp:LinqDataSource ID="dsOrders" runat="server" ContextTypeName="myDataContext" TableName="orders"
Where="orderProducts.Any(op => op.Manufacturer.Contains(@searchTerm))">
<WhereParameters>
<asp:ControlParameter Name="searchTerm" ControlID="txtSearchTerm" DefaultValue="" />
</WhereParameters>
</asp:LinqDataSource>
The error I am getting is:
No property or field 'op' exists in type 'orderProduct' Any clues as to how to get this working within the LinqDataSource definition, or will I have to handle and set up a custom OnSelecting event?

Im using a LINQDataSource to populate a GridView of Universities.
Each University has an associated State, which is in another table and associated by a foreign key (StateID).
I have a TemplateField in the GridView so that when you view it normally it displays the StateName which comes from the State table and when you edit it shows a DDL populated with everything from the State table.
[Code]....
If I debug, inside of RowUpdating, GridViewUpdateEventArgs.NewValues doesnt even have a key for State.
Question: How do I let my gridview know I want it to update this column? All the BoundFields just seem to work...

I have three tables in database:
ARTICLE with fields like ID_Article, Title, etc. and also a FK ID_Author
CATEGORY with fields ID_Category, Name
CATEGORYTOARTICLE with fields ID_Article, ID_Category
Now I have a page that shows all Articles of a given Category. Inside there is a GridView.
[Code]....
The ID of the viewed Category is passed via QueryString.
How to access the fields of Article table so that I can create columns for them in GridView? I tried using Eval("Article.Title") but it keeps saying that "DataBinding: 'konserwatyzm.db.CategoryToArticle' does not contain a property with the name 'Article'."

The datasource of the datagrid is a LINQDataSource which relies on the value of a dropdownlist. In addition, I want to use the footer to insert new records - so I'd prefer not to use the empty dataset template. I am trying to find a way to always display the footer regardless if the datasource is empty or not.
EDIT:
Is there a way to create an empty/invisible object of the type in the LinqDataSource?

I need to use a grid that allows for filtering in the column headers. I know there are some third-party components out there that cost money. I am looking for something that is free / open-source that can be used on a project. Is anyone aware of a GridView that can do this?

I'm trying to display data which comes from a join on two tables (or more) in a gridview I want to be able to filter the result set via user given input (text boxes on page)I have tried the standard tutorials but cannot find something which goes beyond displaying one table result sets in the gridview. If I go through the configure gridview and configure datasource wizard for any datasource (sqlDatasource, object, entitydatasource), when I use multiple tables I cannot use the 'where' parameters in the wizard, and therefore need to have the selecting code in the code-behind, but i'm unsure where exactly to put this.

I am new to web page development so I want to ensure I am going down the right path with this new project. Currently, I am populating a mainGridView on my webpage with infomation from my MS SQL database. Two features I would like to add to this page is to be able to add filtering and hot linking/cell clicking events.
I was also planning on keeping the mainGridView dynamic, so that as a user clicks on a cell I could update the mainGridView with new information. Say all of Sammy Davis' movies. I am trying to do all of this inside of code and leave the aspx alone for the most part.
My plan was to embed textboxes into a secondary GridView to handle the filtering. The user could click on a button to filter the query set and the mainGridView would update based on the filter. Since the mainGridView is dynamic I need to have the filters to be dynamic as well.

Client-side filtering. Begin typing an Item name in the filter box above the "Item" column (Grid View) a live filtering will take a place to filter the input letter till the user find what he/she is lookin for.
you can see a live example in this website [URL]
