I bind a member's ID (primary key of type Int32) to the selectedvalue of a ddl, and the user name to the text. This has worked fine until now. I have just exceeded 255 members and it is crashing when I bind any member with an ID value 256 or greater.My error is, "'ddl3HomePlayer' has a SelectedValue which is invalid because it does not exist in the list of items. Parameter name: value"I think the problem is that a ddl.selectedvalue can't exceed 255. Is this correct? How do I set the selected value to type Int32?

Is there any way-out to over-come this sort of problem in ASP.net
Pardon if this is more serverfault vs. stackoverflow. It seems to be on the border.
We have an application that caches a large amount of product data for an e-commerce application using ASP.NET caching. This is a dictionary object with 65K elements, and our calculations put the object's size at ~10GB. Problem:
The amount of memory the object consumes seems to be far in excess of our 10GB calculation. BIGGEST CONCERN: We can't seem to use over 60% of the 32GB in the server.
What we've tried so far:
In machine.config/system.web (sf doesn't allow the tags, pardon the formatting):
processModel autoConfig="true" memoryLimit="80"
In web.config/system.web/caching/cache (sf doesn't allow the tags, pardon the formatting):
privateBytesLimit = "20000000000" (and 0, the default of course) percentagePhysicalMemoryUsedLimit = "90"
Environment: Windows 2008R2 x64 32GB RAM IIS7
Nothing seems to allow us to exceed the 60% value.
i added autocomplete extender its working fine but the suggestion list half bottom is not showing because its exceed the length of the div containing textbox
I have a WebForms page that has two DropDownList controls on it that both contain a range of temperatures from 60-80 degrees, one for heating the other for cooling. They are declared in the .aspx as:
When I try to set the selected value for each DropDownList using the values in an object containing data loaded from the database using:heating.SelectedValue = myHome.avgHeatingTemp.ToString(); cooling.SelectedValue = myHome.avgCoolingTemp.ToString();
The SelectedValue for both lists is set first to the value in myHome.avgHeatingTemp, then to the value in myHome.avgCoolingTemp. Heres what the values are for each variable after each step of the process of setting the SelectedValues:
Initial State heating.SelectedValue: 60 cooling.SelectedValue: 60 [code]....
As I know, by default Cache is stored in the memory and to the disk at the same time DiskCacheable=true).When the cached response is removed from the output cache due to memory pressure, it still remains on disk allowing a much larger set of pages to be cached. In addition, disk cached pages survive application restarts. And this is already in ASP.NET 2.0.I dont't know in which order the caches are removed from the memory and readen from disk instead? I would like to achive, that caches with the minimal trafic, or the longest last used, would be removed first from the memory. Is there some settings to do that, or even by default works that way?
I'm not sure if this problem is isolated in MVC2 or if it's isolated with the DataType.EmailAddress, but that's what I'm working on.
Anyway, I noticed that no validation is performed at all on my field marked with [DataType(DataType.EmailAddress)], both on client and server.
Here is the Model:
[Code]....
Here is the View:
[Code]....
Here are the Controller Actions:
[Code]....
Validation for the [Required] attributes are working fine. It's the DataType.EmailAddress that never gets checked at all. My ModelState.IsValid returns true even if I enter "x" as my email address. Haven't tried the other DataTypes, so I dunno if this is just for the email or for all types.
I have a web application which talk to Oracle for Database Operations.I want to what will be the equivalent datatype for float in c#.ie for Oracle Varchar2 , in c# we can give string like that for Float in oracle what will we give in C#
I'm working on an application that has a large number of inputs for certain types (50 money inputs, 30 date inputs etc). I have been creating an CompareValidator for each one to make sure users are putting in the correct information but I am curious if there is an easier way to create the validation once and apply it to all desired inputs? Writing out 80 validators that do basically the same thing seems like a waste. Am I missing something that already does this in .NET or are there anything out there that can make validation easier?
Note: All validation needs to be done on both the client AND server side. I've read a little about ASP.NET MVC validation but unfortunately that won't be an option here.
This is actually a situation where LINQ as follow:
Code: Dim query = From loadedfile In dtloadedfile.AsEnumerable() _ Join householdPanels In dtHouseholdPanels.AsEnumerable() _ On CType(loadedfile("Household_number"), Integer) Equals _ [code]...
when i get to col.DataType = t.PropertyType, i hit an error where it says Nullable datatype is not allowed. I know the t.propertytype returns nullable as datatype, however, this nullable type do have a normal datatype declared too. ie Of System.Nullable(Of Integer) from the LINQ query. But how do i get that information?
ps: this function is taken somewhere from the web, so you might recognise it.
In MSSQL server 2005/2008, we have one column (in a table) declares as "Image" type. What data type in C# so I can grab that value in that column in our class? Can string handle it or byte[]?
I have a tabe related to songs which has columns like songID, album, Artist, track etc. I want the data for track to be entered in the format 1/2, 2/2 like this. What shpuld b the datatype of this value? If I'm entering a new data or updating the columns from a web page how can I check the track textbox to enter the correct value? Can I use any validation control? if so how can i use it?
How can I get asp.net to two-way databind (via Bind("myfieldname")) to a Byte value? I'm storing boolean values in Sql Server to a Byte type and it seems to be looking for boolean. Apparently I need something to convert my datasource's Byte
Looked into creating a method to call like MyConvertMethod(Bind("myfieldname")) but asp.net 4.0 did not allow that with "Bind()" though it allowed it with "Eval()" but Eval only seems to do one way databinding. I looked into the ConvertHandler but seems to be winforms and not webforms.
i have a website written in asp.net c#. it was using a sql 2005 db but due to requirements we have ensure it's compatible with a sql 2000 db. everything on the site converted ok except for one page that is using a stored procedure to read in a marquee. the @Url_FK variable is no longer being passed to the page via the stored proc.
The only difference in the table design is 2005 uses nvarchar(max) and 2000 uses varchar(8000) for the TOD_Text field.
I'm currently developping an application using MVC2 and Globalization (fr and de). I'm creating a form who use DataAnnotation on the model for validation, with localized error messages in my dataAnnotations.
Here is the trick :
I have two <input /> :
One for a required date (example : 12/05/2001) wich is a DateTime field in the model :
[Code]....
One for an optionnal hour (example : 22:30) wich is a DateTime? :
[Code]....
Erreur and LibellesSinistre are my ressources files.
I got two problems :
I can enter a date in my hour field and an hour in my date field.My error messages aren't localized. Do I need a trick or something to make it work ?
I'm using Cute Editor for ASP.NET for the first time, and it's occasionally refusing to insert or update a record. Basically the records are just composed of a bunch of HTML and text. So far I can't detect a pattern to the problem and I'm wondering about my data type.
I tried VARCHAR(MAX), NVARCHAR(MAX), and NTEXT, doesn't seem to fix it.
So what is the best SQL data type for HTML?
And could that be causing CuteEditor to refuse to insert/update records? Or something else?
