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.

How it is possible to assign datatype of an attribute retrieved using sql query to a string? for eg:

I want to assign this datatype value to a string. How it is possible?
I'm loading data from my database into a DataTable, and one of the columns is a date field.
[Code]....
I'd like to format that column so that instead of containing a full date, it will be formatted like "MM/DD/YYYY".
I've tried looping through each row in the table and changing the cell for that column, but I get an error saying that the string isn't a valid DateTime object.
I tried changing the column DateType to a string, but I get an error saying I can't change the DateType after the table is filled.
How can I do this? This seems like such a simple thing, but I'm having so much trouble with it.
Are there any disadvantages to always using nvarchar(MAX)?
Is there a general downside by chosing 'ntext' as column type instead of a type that contains chars but with a limited max size like 'char' or 'varchar'?
I'm not sure whether a limited column size is applyable to all my colums. Therefore I would use 'ntext' for all columns containing text. Might this lead to problems in the future?

I have a column with nvarchar datatype storing the date. I am using a Gridview to display and edit data of that table. Now when I update the table the nvarchar column containing date in the format mm/dd/yyyy gets converted to Jun 9 2010 12:00AM format. I don't want this to be happening. I don't understand why this is happening as I don't have datetime column.
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?
