My knowledge of VB is rubbish, but I would say the problem is as follows:
cmd.ExecuteScalar() returns object, which is supposed to be array of bytes,
but your call CByte(cmd.ExecuteScalar()) is trying to convert this object into object of type byte (not array of bytes) and that causes your error.
Unfortunately, I don't know correct syntax in VB for casting object into array, I hope you do (otherwise you have to google it  )

ASP.NET Ajax doesn't support in .NET 1.1.
So, you have to choose other Ajax frameworks.. there are a lot of free ajax framework for ASP.NET 1.1. Check-out the link below if you interest..
Ajax Frameworks and Others.
If you are good at Javascript, you can probably use Prototype Javascript Library.

details view control or data grid control ? From where does your filter criteria come from.
|
|
|
|
|
In the insertitemtemplate in the details view.
in the dropdownlist I can show the items all I need is to filter these items to a 3 char input from the user.

Your client disable Javascript on his/her browser?
It is not possible to change the client's setting from web application. It is for security reason. So, what all you can do is that check whether the Javascript is enabled or disabled for the user's browsers. If it is disabled, you should check the validation from code-behind.
Since Ajax web application are so popular day by day, I don't care about those users who are disable the Javascript in my project. But Yes, the requirement may be varied from project to project....

You can not. That would mean intruding into user's personal browser preferences. I would say, you can have a disclaimer or an instruction to the user about required support for JavaScript in the web browser for your application to perform normally without insanity.

You can add a pager template then add a dropdown list box on that template which shows the page number. So every time you select on that dropdown the datalist will cange according to the page number you selected. =p

I did the following to fill tha datagrid
1.Through the vb code ,dyanmically add the template column and bound column in my datagrid.
In that template column i add a link button .
2.In the page load call the function to fill the datagrid
3.In datagrid item command event i wrote the code for the link button to redirect to someother page.
4.It's working properly
5.Next I add a button in the page
6.In the button click event i wrote the code to delete the selected items in the grid.
7.It's not working
8. If i write the code in the page load like this,
If Not IsPostBack Then
FillDataGrid()
End If
the button event is working. But link button event is not working.
9..If i simply call the funtion FillDataGrid() in page load means Link button event is working,
but the button event is not working11:18
