Refresh data in a Bound datagridview VB.NET
I have a datagridview in a Windows Forms Vb.NET App. The datagridview is filled in the following manner.
Dim daLines As New SqlDataAdapter("Select L.CIV_LINE_ID, L.CIV_HD_ID, L.LINE_NO, L.PRODUCT_CODE from IMPORTED_CIV_LINES L WHERE L.CIV_HD_ID = '" & grdInvoiceList.CurrentRow.
daLines.Fill(dslines, "LINES")
grdLines.DataSource = dslines
grdLines.DataMember = "LINES"
As I do some cell formatting the dslines is declared as a public var.
The datagridview is filled when the user selects a row in another grid.
What I have found is that the datagridview is not clearing. The results are appending to the results of the last time it was filled. I thought I would then perhaps try to delete the contents of the datagridview and re-fresh/re-read when the DA Filled the DS. I cannot get this to work.
Can anybody provide me an easier way of refreshing data in a datagridview from a Dataset ???

I know that i have tried this before, The Problem was that it failed initially. I put the Table.Clear inside a Try Catch block and all worked.
Thank you for your help

Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to Visual Basic pre-2002, it is not the same technology,
