Hi,

I have a datagridviewcombobox added programmatically. How can I set a default value for each row. I would like the default value to be "No"

Dim dt As New DataTable("tblFirstDatagrid")
               dt.Columns.Add("Passed?")
               dt.LoadDataRow(New Object() {"Yes"}, True)
               dt.LoadDataRow(New Object() {"No"}, True)
               dt.LoadDataRow(New Object() {"NA"}, True)
               .dgTroubleshootingandResolution.DataSource = dt
               .dgTroubleshootingandResolution.AllowUserToAddRows = False
               .dgTroubleshootingandResolution.Columns.Remove("Passed?")
               Dim cmb As New DataGridViewComboBoxColumn
               With cmb
                   .Items.Add("Yes")
                   .Items.Add("No")
                   .Items.Add("NA")
                   .DataPropertyName = "Passed?"
                   .HeaderText = "Passed?"
                   .Name = "Passed?"
               End With
               .dgTroubleshootingandResolution.Columns.Add(cmb)

I've tried the code below but it's still not working.

What I have tried:

dt.Columns("Passed?").DefaultValue = "No"
