Vb net datagridview not updating
I have a Drop Down button in a Tool Strip that filters on one of the DGV's columns. Here's the code for the filter button dropdown: Private Sub ts DDItem Btn Filter All_Click(sender As Object, e As Event Args) Handles ts DDItem Btn Filter All. Remove Filter()End Sub Private Sub ts DDItem Btn Filter Yes_Click(sender As Object, e As Event Args) Handles ts DDItem Btn Filter Yes. Filter = "caculate = 'Y'"End Sub Private Sub ts DDItem Btn Filter No_Click(sender As Object, e As Event Args) Handles ts DDItem Btn Filter No. Filter = "caculate = 'N'"End Sub Private Sub ts DDItem Btn Filter Blank_Click(sender As Object, e As Event Args) Handles ts DDItem Btn Filter Blank. Filter = "caculate IS NULL OR caculate = ''"End Sub Here's the code for the Click event for the Save Changes button for the DGV: Private Sub ts Btn Dgv Employees Save Changes_Click(sender As Object, e As Event Args) Handles ts Btn Dgv Employees Save Changes. Suspend Binding()Save Employees Changes()Dim new Data Set As Data Set = Employees Data Set()If Not new Data Set Is Nothing Then Me. The filter works fine until a change is made in the Data Set (edit the contents of one of the cells in a row and save the changes). Command Text = "UPDATE employees SET emp_name = @emp_name, start_date = @start_date, end_date = @end_date, util_start_date = @util_start_date, " &"caculate = @caculate, Third_Party = @Third_Party, Owner = @Owner, Role = @Role, Job Class = @Job Class, billable_goal = @billable_goal, utilization_goal = @utilization_goal " &"WHERE Employees ID = @Employees ID"updt Cmd. Here's the update code (called by the Save button)Private Sub Save Employees Changes()Try Using sql Conn As New Sql Connection(conn String)' Set up UPDATE command object Dim updt Cmd As New Sql Command()updt Cmd.

These text fields represent eight of the fields in the Customers table in the Northwind database.The value of the Row State property for the other row remains Unchanged.In addition, it contains constraints and relationships defined for the dataset.I used the designer to create the grid columns that map to the [Fruit] database table we created. The connection to a database normally consists of the below-mentioned parameters.The code is as simple as possible, which means eliminating many of the error-checking and exception-handling routines you might expect in a production program.
