.NET Checkbox Databinding To Byte Datatype?
Mar 1, 2010
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 am develping an application that integrates with an RFID kit. The problem is, the kit comes with an .cs class that accepts data stored in a byte array however, each information stored in the array respresents an int. I wanted to store String information in each array but, my research suggest that a String itself can be converted to a byte array and not a byte....here the code from the .cs class:
byte BlockNo = 0;
byte[] BlockData = new byte[16];
byte ReturnCode = 0;
[code]....
Each t_b*.text respresents an int. Is there a way I can stored a String in a single byte block?

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?

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'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.

I have a working application to save an image file to my sql database (Saves as "Original_Image" in the DB TBL_ImageGallery). I have a file limit on the upload of 1 MB. This also works great and the image is being saved beautifully. I found a bit of an issue. Being i am working on a network with 2 bonded T1 connections the streaming of images to my site, when tested internally, is effortless. I am not sure that this will be the same with a generic bandwidth. I want to store the original image size into the databse (already done) but also store a smaller sized (in bytes not actual size [Width, Height]) to my database in a "ThumbNail" column. This will allow the browser to only have to pass the "Thumbnail" sized image, obviously this needs to be much smaller than the original (ex: 1MB orignal I want to save as 12KB image in the thumbnail column), to the thumbnail img control in the user's interface.
I am not sure if this is possible or if there is a need of third party controls. I am interested in doing this as either a stored procedure or in the C# code on an event fire. There may be a better / other solution to this and if that is the case I am also interested

I want to send an email that has a machine readable part you cut and paste into an asp.net page and you get the information. I have stored all the information in an object and then used an XMLSerizer to create some xml. It all worked fine until I added some Images as byte[] to the object. If I dump the resulting string to disk then I can recreate the object fine but after it appears in the email client and I try to cut and paste it it never works. Clearly there are non standard characters coming out that email clients don't like.
Is there some encoding I could apply to my XML that would make it display correctly in an email client? Then I could cut, paste, decode and deserilize to get my object back.
