Updating database datagridview vb local sex and dating

When the user clicks the "Select Facility" button, you would like to clear the Data Grid View of the data from the previous facility (and not throw an error if it's his first selection).In this scenario, you can achieve the clean Data Grid View by adapting the generated code that fills the Data Grid View.Keep getting this err msg at the high-lighted code, "Object reference not set to an instance of an object". Ole Db Public Class Form1 Dim my DA As Ole Db Data Adapter Dim my Data Set As Data Set Private Sub Form1_Load(By Val sender As System. Open() my DA = New Ole Db Data Adapter(cmd) 'Here one Command Builder object is required. Update Command = New Ole Db Command("UPDATE Table1 SET Field1 = ? ") 'It will automatically generate Delete Command, Update Command and Insert Command for Data Adapter object Dim builder As Ole Db Command Builder = New Ole Db Command Builder(my DA) my Data Set = New Data Set() my DA. I have been struggling with the below code trying to get it to work. I have never used the Ole Db Data Adapter & Ole Db Command and am not sure what I am doing. The Data Grid View control uses several column types to display its information and enable users to modify or add information.

Data Source = Data Set.table Nb:instead of table put the real name of your table ex: datagridviewer.

The datasource i used was a datatable having no columns, and i added columns and rows programmatically to datatable. I tried the code related with gridview like 1) create button named it Clear. Data Source=nothing 2) In your search button begin your code by the following statement datagridviewer.

Data Source = data Stuff End Sub End Class I had the same problem on gridview content clearing.
