View 5 Repliesi have a problem regarding datagrid.remove and textbox. This is a Function to Add and Subtract Values on a specific Column. If I cellclick on the main datagrid on a specfic row which has record where the record goes to the other datagrid with no record yet to be filled with record, the textbox will count/ add all the values from the UNITS COLUMN and in an instance on one row removed in the other datagrid, the total value of units in the textbox does not subtract or less. here's the code.
Public Function total_units_remove() As Double
Dim totalunits As Double = 0
Dim i As Integer = 0

I am going crazy trying to figure this one out. I have been told many times that you can get the data of a column in a listview in this manner: YourListView.SelectedItems(0).SubItems(1).text This does not work. I have a ListView called EmployeeListView that is correctly populated by my database. There are three columns: (0) is First name, (1) is Last name and (2) is Employee ID. I can see the information in the ListView when I run the program. What I need to do is to pull out the Employee ID and put that into a variable called EmpID.
