Answer : How to add a combobox,calender to a DataGrid view column and bind it from database

You'll need to add columns to the datagridview manually.

Any object you can add to a combobox as a datasource can be added to a DataGridViewComboBoxColumn

As for adding a DataTimePicker (for example) to a datagridview, it's possible, though you'll have to extend
DataGridViewColumn, DataGridViewTextBoxCell, and DateTimePicker that implements IDataGridViewEditingControl

                       
                   // Create a new combobox column and add a few items
      DataGridViewComboBoxColumn comboColumn = new DataGridViewComboBoxColumn();
      comboColumn.Items.Add("Foo");
      comboColumn.Items.Add("Bar");
      comboColumn.Items.Add("Baz");
 
      // DataPropertyName is the field that the column gets it's information from
      comboColumn.HeaderText = "Header Text";
      comboColumn.DataPropertyName = "col1";
 
      gridValues.Columns.Add(comboColumn);
