Add column dynamically in datagridview

[nnuswantari]

I have a datagridview with 1 column and any rows. I will use this to entry any data. What can I do to make this column can be added dynamically in runtime???

dim DcDtb as new datatable
dim SlCm As New DataGridViewTextBoxColumn, MgpCm As New DataGridViewTextBoxColumn, ImCm As New DataGridViewComboBoxColumn


DataGridView1.DataSource = DCDtb
DataGridView1.Columns.Remove("sl_no")
DataGridView1.Columns.Remove("mgp_sln")
DataGridView1.Columns.Remove("itm_description")

DataGridView1.Columns.Add(SlCm)
slcm.DataPropertyName="sl_no"
DataGridView1.Columns.Add(MgpCm)
MgpCm.DataPropertyName="mgp_sln"
DataGridView1.Columns.Add(ImCm)
ImCm.DataPropertyName="Itm_Description"

blah....blah...blah....
