Forms Data Controls :: List Of Anonymous Types At Page Scope?
Nov 21, 2010
I have a listview in which I have a dropdownlist that will be repeated about 8 times. In the itemdatabound event of this listview, I fill the dropdownlist of that particular row with data. I obtain this data by using a linq query. It gets me an anonymous type in return:
[Code]....
The problem with this code is that I fire a query to the database everytime the itemdataboundevent is called. What I want to do is to fire the query only once, and have it available at page scope so I can reference it in the itemdatabound event. How can I get it like that?

I am currently implementing a client-side paging solution using ASP.NET, jQuery and JSON.
I have been following the excellent article from encosia: http://encosia.com/2008/08/20/easily-build-powerful-client-side-ajax-paging-using-jquery/
In my Web Method I retrieve my data from the database as a DataTable:
DataTable categoryProducts = ProductViewerAccess.GetCategoryProducts
("AA", 4, 0, Page.ToString(), out howManyPages, "FALSE", 0, "CostPrice", "asc", destinationList);
I then retrieve the data from the DataTable into an anonymous type:
var feeds =
from feed in categoryProducts.AsEnumerable()[code]....
This all works great.
However, I would like to extend the code to perform some evaluation checks (e.g., check that various columns in the DataTable are not NULL) and other pre-processing (e.g., call various functions to build the image URL based on the image ID - which is another column in the DataTable not shown in the code fragment) before I return the resulting rows of the DataTable as an anonymous type to the client-side.Basically, I want to iterate through the DataTable, perform the evaluation checks and pre-processing, while building my anonymous type manually as I go. Or maybe there is a better way to achieve this?

nested repeater like this:
<asp:Repeater ID="repeaterReportListByJob" runat="server" DataSource='<%# GetReportsByJobNID(Eval(Container.DataItem, "JobNID")) %>'>
It seems my Eval(Container.DataItem, "JobNID") is not working and I assume this is because the datasource of the outer (parent) repeater is an anonymous type. So how am I supposed to access a particular field of my anonymous type?

I m Using a GridView: Columns: "Ser_type" tells what type of data is it i.e. VC for Varchar, NU for Numeric, DT for DateTime etc, for the time being i m using datavalidation controlls at design time. this is not a good approach. I just wan to do is that, DataValidationControlls should be created at RunTime and TextBox should validate data at runtime only. i.e. if Data required in the TextBox is of Type VC then it should validate only at runtime, if DT then validate DateTime only at Runtime similarly for all dataType:

There are two dropdowns for date (Fromdate and Todate) in my webpage and by default when the page loads for the first time the dropdowns loads with the last date (currentdate), if I select some previous date in Fromdate dropdown and reload the page then it displays runtime i.e.
Object cannot be cast from DBNull to other types.
Following code is written under GridView RowDataBound Event.
[Code]....
The error found at following line:
less7daysTotal += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "less7days"))
If I comment this line then the error moves to next line till following line.
grt28daysTotal += Convert.ToInt32(DataBinder.Eval(e.Row.DataItem, "grt28days"))
I fruther want to inform that some columns in the grid are showing 0 if there is no record but I replaced 0 to - then some 0s replaced and some not. What is the reason?

I would like to ask a question about hiding a drop down in my gridview. I have a gridview and I have a drop down list to control the page size of that gridview. when there is data in that gridview, it is fine for user to see the drop down list. But when there are records in the gridview, I do not want the user to see this drop down list. How can I hide it when there is no data?

I didn't had any problem using datagrid to display Sql table on ASP.NET page,
but as the table grows so as the datagrid, and now the item list is too long for one page.
So I would like to break the datagrid into several pages with page numbers. ( <1,2,3,4> click the number to go to next page)

I have a gridview with paging. So for instance, I'm on say the page number 10, and I open the form details on a specific record_id (link). After I update/submit the form, it returns to page number 10. But, if I go to another page, for instance page 5, and submit the form, it returns to page 10.
I've tried some things, for instance history.back(), but it returns to the first page I went to, in this case page number 10 (or whatever the first page I go to).

i want to see the sales in the grid view based on the month selected from drop down list. Ex: when I select June 2010 from the ddl box, the sales for that month are correctly displayed in the grid view. I go to page 4 to look at some sales there and then switch the month to August 2010 to see sales for that month instead. Here is the problem. When I switch the month, it show August 2010 sales, but stays in page 4 instead of going back/resetting back to page 1 of August 2010 sales.
How do I reset the grid view page back to the first page of August 2010 sales?
I am fairly new to ASP. If I have missed an imp. detail in this post, let me know and I will get that info. out there.

I am using two data list one at the bottom & another at the Top to display paging. On Page load, I need to access link button placed inside Data List. Actually I had got two Datalists. I can access one Datalist Link button like this:
LinkButton lnkPg=(LinkButton)dlPg.Items[0].FindControl("lnkbtnpaging");
lnkPg.Visible= false;
This is giving no error. But if I write same code for another datalist say dlPg1, it is giving error: Index was out of range. must be non-negative.

I have an application that allows admins to add types such as document types and training types that are in seperate tables with a foreign key in a transaction table.
When structuring my class I decided to go with an abstract-like pattern (without the factory methods though). So I have a Type abstract class that defines my Save, Delete, and GetList methods. I have a training type class that inherits this class. The thing is all types have 3 main properties - defined in the abstract base - but have different source tables and thus different store procedures in my DbCommand object. So basically I repeat setting up the same parameters on all the derived classes. I would like to implement the common stuff in the base but I am getting thrown off by the difference in data sources.

I have one page that checks the content type then either returns an XML or a Plain Text page.
On IE6 (Unfortunately still the corporate standard) viewing XML content works but when I try and view the Plain Text content it reports: The XML page cannot be displayed. Invalid at the top level of the document. Error processing resource.
On Firefox it works perfectly, displaying an XML document for XML content and a plain text document otherwise.
Is this a bug with IE6 caching the content type? The URL is the same but the query string is different for different entries.
Here is the code that generates the output. I have single stepped it and it goes down the Plain Text leg when I expect it to, but IE still reports the XML error:

I have an SQL Server table named "Fields" with an autoincrement identity column "FieldID" as the primary key, an nchar column "Phrase" that textbox entries are to be stored in from a web page, and another column that is defaulted to null. The following is the recommended example on how to use Scope_Identity() to get a newly inserted table row identity value:
//C#
string query = "Insert Into Categories (CategoryName) Values (@CategoryName);" +
"Select Scope_Identity()";
int ID;
string connect = @"Server=.SQLExpress;AttachDbFilename=|DataDirectory|Northwind.mdf;" +
"Database=Northwind;Trusted_Connection=Yes;";
using (SqlConnection conn = new SqlConnection(connect))
{
using (SqlCommand cmd = new SqlCommand(query, conn))
{
cmd.Parameters.AddWithValue("@CategoryName", Category.Text);
conn.Open();
ID = (int)cmd.ExecuteScalar();
}
}
Obviously, this example uses a Categories Table in a Northwind database, which I do not have. So I am confused by how to adapt this example for my application. The following is my data context:
DataClassesDataContext db = new DataClassesDataContext();
Could you explain how I can adapt the example for my "Fields" table in my "EFMDB" database?

Is there an easy way to cache ASP.NET whole page for anonymous users only (forms authentication used)?
Context: I'm making a website where pages displayed to anonymous users are mostly completely static, but the same pages displayed for logged-in users are not.
Of course I can do this by hand through code behind, but I thought there might be a better/easier/faster way.
