C# - TemplateField Not Updating In GridView Using LINQDataSource?
Sep 2, 2010
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 one two GridViews on a page. One Gridview uses BoundFields inside of the GridView and the Update statement works just fine. The other GridView utilizes TemplateFields due to the fact that Validation Expressions have to be used. I also want This GridView to be able to update the vlues when the user clicks on the Update link on the right side of the GridView. The GridView that uses the BoundFields updates just fine, but the GridView that uses TemplateFields will not update. I have checked and everything is correct other than this difference of BoundField and TemplateField.

I am trying to update values in the GridView but have some issue with the Datetime (which I want to keep Readonly). On updating the GridView, I am getting the following error:
ERROR: "System.FormatException: Input string was not in a correct format."
Database COLUMN:BestillingDato, nVarchar(50), Allow Nulls
HTML Form:
<asp:TextBox ID="txtBestillingDato" runat="server" Width="260px"></asp:TextBox>
GRIDVIEW Table:
<asp:TemplateField HeaderText="Bestilling Dato">
<ItemTemplate>
<asp:Label ID="lblBestillingDato" runat="server" Text='<%# Bind("BestillingDato","{0:d}") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>

My GridView is not updating when AutoGenerateColumns="false" and have TemplateField. It works fine when I comment out the BoundField and TemplateField and change the AutoGenerateColumns to true. Am I missing something?? Below is the markup:

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 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 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?

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?

How can I hide a column in a GridView ?
I tried using the markup:
<asp:TemplateField ShowHeader="False" Visible='<%# MyBoolProperty %>' >
<ItemTemplate>
<asp:LinkButton ID="attachmentButton" runat="server" CausesV
CommandArgument='<%# bind("ID") %>' OnClientClick="$('#b
Text='<%$ Resources:Resource,Attachments %>'></asp:LinkB
</ItemTemplate>
but it didn't work and gave me the following error:
Databinding expressions are only supported on objects that have a DataBinding event.
System.Web.UI.WebControls.TemplateField does not have a DataBinding event.
I tried also to hide it programmatically, but seems I can't reach to the column by name (there's no name for TemplateField column).
