View 3 Repliesit's a multiline TextBox the MaxLength property does not work.

View 4 Replieshow i can generate a gridview with a fixed number of rows that is entered from a textbox
my gridview has a column with dropdownlists the others contains textboxes?

View 5 RepliesI have a table that contains about 8000 records and I need to be able to select any given sequence of 250 subsequent rows by a specific row index of teh table...
how I can go about that easily using a dataview without building a secondary table and just pushing the records I need into it?
I've searched for this several times but have never been able to find the answer with my search terms. Say you have a listview and a datapager set to 10 rows, but you only have 4 data items in the database at the time the query is run. Is there a way to force it to show a 10 row table (4 with data and 6 without)?
Everytime I search on this, I just find information on setting the number of rows for the datapager, which will not show empty rows if the data isn't there. Probably an easy solution, but the heck I can find it.
