Forms Data Controls :: Calculated Field Sorting Now Working?

although i had to take the table that has my calculated column and make a view (so i could filter) and then bind the gridview to the view.

My question is as this.

1.) in order to get my calculated field i had to load my data into a table (as suggested)

2.)Add a column to the table and perform calculations

3.)make a dataview from the tables because i could not get the Gridview.datasource= ds.tables("loads").select("Deadhead <= " & sngRadius

4.)the largest of the 3 tables my query is based on contains about 7000 records. The way i have the logic & programming now everytime a new "truck location" is put in the textbox1 and "find loads/button1" is clicked. It calculates the deadhead miles of all 7000 records before filtering. I am filtering based on the deadhead miles.

Does anyone have any recomendation about how to speed this up a bit.

Also in order to get paging to work i had to rebind/filter the data again ... means looping through all 7000 records each time paging is called. This seems terribly ineffecient as i am already forced to use access instead of SQL.

Would i see a performance increase if i installed SQL or mySQL and create linked tables to the ones i use in access. or would access still be the bottleneck?

I don't know if the performance increase would be negligible as i still ultimately be getting the data from Access.

I have posted the entire code for the page below. When i originally started i didn't think there would be to much code so i left it all on one page instead of using code-behind. Would i gain anything by swapping to code-behind now?
