hello, i am creating column of DataGridViewComboBoxColumn and binding it.
it working fine.

but when i fill the grid manually it not shows me value...

in the DataGrdcombo

Hi,

If comboboxcolumn.datasource contains the boundtext, this will make comboboxcolumn show the correct display text.

You can try the following example.

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

'DataGridView datasource

Dim dt01 As DataTable = New DataTable()

dt01.Columns.Add("Mill")

dt01.Columns.Add("tag")

dt01.Rows.Add("01", "test01")

dt01.Rows.Add("02", "test02")

'comboboxcolumn datasource

Dim dt02 As DataTable = New DataTable()

dt02.Columns.Add("DepartmentName")

dt02.Columns.Add("DepartmentID")

dt02.Rows.Add("name01", "01")

dt02.Rows.Add("name02", "02")

DataGridView1.AutoGenerateColumns = False

DataGridView1.DataSource = dt01

Dim Col_Mill As New DataGridViewComboBoxColumn

With Col_Mill

.Name = "Mill"

.DataPropertyName = "Mill"

.DisplayMember = "DepartmentName"

.ValueMember = "DepartmentID"

.DataSource = dt02

.Width = 150

End With

Dim datagridviewtextboxcolumn As New DataGridViewTextBoxColumn

With datagridviewtextboxcolumn

.Name = "tag"

.DataPropertyName = "tag"

End With

DataGridView1.Columns.Add(Col_Mill)

DataGridView1.Columns.Add(datagridviewtextboxcolumn)

End Sub

If you have further questions, please feel free to tell me.
