DataGridViewComboBoxColumn not showing the contents

[sachinkalse]

Hi I am trying to insert a DataGridViewComboBoxColumn, the column is getting inserted but without values (options) in the combobox. The Code is as under DataGridViewComboBoxColumn column = new DataGridViewComboBoxColumn(); column.HeaderText = "SELECT"; column.Name = "ItemSelect"; column.CellTemplate = new DataGridViewComboBoxCell(); column.Items.AddRange("One", "Two", "Three"); column.DropDownWidth = 160; column.Width = 90; column.MaxDropDownItems = 3; column.FlatStyle = FlatStyle.Flat; myDataViewGrid.Columns.Insert(0, column); When I run the code, in datagridview all cells except 1st are populated properly, in first cell I see only empty combobox. Also, after showing the value, which event should I use to get the selected value of combobox? Please guide Thanks in advance
