There is no combo box. I suppose that you mean a dropdown list, i.e. a select element?
How many items that is shown in the list is chosen by the browser, and nothing that is defined in html.

b { font-weight: normal; }

Use listbox rather than going to commbo box/ drop down list.
If u want to show only 5 element then set the height accordigly.

I have a database in SQL Server 2000 and want to modify and delete entries in it using datagrid. How?????

Do you want to delete a particular row in datagrid? If so then you can use itemcommand event for that, there you can write the code to delete the record and again rebind the datagrid.

Look there are multiple ways to do that one is you loop through all the number of records to be deleted and execute the delete statement.
second one is you send alll the id as a comma separated value to the query like this:
delete from table1 where id in (1,7,43,7)

How can I make a datagrid editable?? So that I can modify values + delete the selected rows in dg..??

either you can use datagrid built in edit and delete functionality or you can use your own one.
BTW Here[^] you can get lot of example related to datagrid.

Put one button column in datagrid, which has command name as "delete"
Now in ItemCommand write as
Select Case e.CommandName
Case "delete"
//Do all deletion operation here
//Assign datakey value of datagrid to one variable like
Dim ID as string = DataGrid1.DataKeys(e.item.itemindex)
// SQL Query is
"delete from table_name where Column_Name = ID"
// here Column_Name is the primary key column of ur table.
End Select

Hi,
I am Ravindra ,currently doing a project in asp.net.
I was given a task of "registration form for new users in a matrimonal site".
In the Regform there is dropdownlist in which when we select OTHER ,
the Regform.aspx is redirected to Subcaste.aspx
there the user enters the values and presses submit button
the page is again redirected to Regform.aspx.
My problem is the values which are previously entered by the user in RegForm are getting cleared.
So, please say how to preserve the values.
thanks in advance...
-Ravindra

you can use sessions or querystring to store the values and again set the values to the dropdownlist.
