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.

View 5 RepliesHow 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?

View 5 Repliescan u tell me what datatype i should use for TimeIn and TimeOut of the employee in database.
In frontend i am storing TimeIn and TimeOut as object.
You'd think since MS SQl Server 2008 and asp.net are both Microsoft products, asp.net would support the new "time" datatype but anyway.
This is one data field in gridview called "timesort"
<asp:templatefield HeaderText="timesort" SortExpression="timesort">

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?
