DataSource Controls :: Form Freezing On "Search As You Type"?

Jun 28, 2010

I write a code which give intellisense on a textbox on text_changed event by using autocomplete. This autocomplete get data from database (SQL Server). It works fine but problem is, the form gets freeze while searching data on database. Even sometimes it won't give any intellisense or application get crash (rare case).

Any improvements I can do in this code:

AutoCompleteStringCollection acnm = new
AutoCompleteStringCollection();
object locker =
new
object();

DataSource Controls :: Filter Parameters/Search Form

Oct 10, 2010

I've got a gridview that I need to perform filters on. All works great until I try and add a date range..

Below is the code. Basically I have 5 dropdown lists which all filter as expected giving them the option to use each one or just the ones they need.

The problem is they want to also have the option of filtering by date i.e date range or greater than or less than or equal to etc..

As soon as I add the date parameter it stops the other filters working. I'm guessing because I have a null value in the date field (textbox) if they dont use the option??

Does anyone have a sample on how to filter by dropdown lists and dates keeping in mind they wont use all the filter options?

Visual Studio :: Clear The File Type To Search From The Search Box?

Feb 22, 2010

I have Visual Studio 2005 and 2008 installed on my machine. When I bring up the Find and Replace box in 2008 in any project the 'Look at these file types:' option is blank however in 2005 it keeps defaulting to the file type of RemoveFile. If I don't remember to clear it then it causes my search to fail. Does any one know how do I reset this value or remove this default option so the file type is not set and it looks at every file type when I search for a word.

I get the error - Conversion from type 'DBNull' to type 'Integer' is not valid. - on the line.....

Dim newid As Integer = e.Command.Parameters("@latestRowId").Value.........in vb code behind.

I have the identical code for another page with the exception of the field names and it works fine.

I don't know what the problem is. Does anyone see any problems?

DataSource Controls :: How To Cast Concrete Type Created In LINQ Query To The Corresponding Interface Type

May 3, 2010

I have an Interface that has its concrete class defined via a factory. Because of this I found no way to use the Interface tpye directly in my LINQ quesry so I had to use the concrete class types to creat a generic list. The LINQ query works but after calling.ToList() on the LINQ query result I get a List(of MyConcreteClass), but I need a List(of IMyConcreteClass). I have tried everything I can find: .Cast, Ctype, implicit casting, etc. but I always get back one of the (2) messages (depending on if I attempt to cast)message:

"Unable to cast object of type 'System.Collections.Generic.List`1[MyConcreteClass]' to type 'System.Collections.Generic.IEnumerable`1[IMyConcreteClass]'."
...or
"Unable to cast object of type '<CastIterator>d__aa`1[IMyConcreteClass]' to type 'System.Collections.Generic.List`1[MyConcreteClass]'."

DataSource Controls :: The Null Value Cannot Be Assigned To A Member With Type System.Decimal Which Is A Non-nullable Value Type

Dec 22, 2010

I am making a website to store invoices so i can mail them to clients. So i got a table for clients, invoices and one with invoice products/services. When an invoice has no products/services added to them and it returns null i get the error "the null value cannot be assigned to a member with type System.Decimal which is a non-nullable value type."

I just started with linq. Before i always used mysql. Mostly i just had to call data from 1 table so forgive me if my linq query isn't really correct.

Dim invoices = From i In db.invoices _
Group Join p In db.products On i.id Equals p.invoiceId Into invoiceProducts = Group _
Select New With {i.client.naam, i.titel, (From iP In invoiceProducts Select iP.prijs).Sum}

i show the client's name, the title of the invoice and the total amount the clients will need to pay for products and services.

Data Controls :: JavaScript And CSS When Freezing GridView Column Headers

Jan 25, 2012

I recently applied a javascript code from article "Dynamically freeze ASP.net Gridview header using Javascript" found here, ASP Snippets Article, to my page. The javascript works great, but somehow, it's overriding my CSS code for the headers.  When I refresh the page, I can see the headers with my CSS in place for just a fraction of a second before it is replaced with generic styling.  I am not a javascript person, so really can't troubleshoot the problem.  I have a style sheet with the following code.

.dGrid {
