Hi,
I am trying to clear the rows of a bounded datagridview without clearing its dataset. I cannot clear my dataset since i m using ds.update() to update changes from my datagrid to the sql database. On every new selection from the combo box( cb_video) the details are inserted in the dgv. Few columns are to be updated by the user and the entire row is saved in the db but when the next selection is made i do not get the modified columns of my previous record ( apparently they do appear to be saved in the db) but i do get the previous records which i do not want. All the help will be appreciated
THanks :)
Private Sub cbvideo_SelectedIndexChanged_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cbvideo.SelectedIndexChanged
Dim da1 As New SqlDataAdapter
Dim ds1 As New DataSet
Dim titem As String = cbvideo.SelectedItem
Dim cmd As New SqlCommand("insert into technical_tb(tech_category,tech_item_name) values ( ' " & tcategory & " ',' " & titem & " ')", c.con)
c.open()
cmd.ExecuteNonQuery()
c.close()
da = New SqlDataAdapter("select * from technical_tb where tech_id >= (select max(tech_id)-' " & ct & " ' from technical_tb)", c.con)
ct = ct + 1
Dim cmdBuilder As SqlCommandBuilder = New SqlCommandBuilder(da)
da.Fill(ds, "technical_tb")
da.Update(ds.Tables("technical_tb"))
ds.AcceptChanges()
DataGridView2.DataSource = ds.Tables("technical_tb")
