绑定网格的DataGridViewComboboxColumn

Question

I am developing a Windows Desktop application in C#.net. I have a DataGridView bound to a DataTable . I want one of the columns to be edited with DataGridViewComboBox .The code is below

string query = "SELECT ResultId, LabId, Result, Comments FROM T_Result WHERE LabId = " + labId;
DataTable dtResult = getQueryResult(query);
dgvResult.DataSource = dtResult;

Now I want the Result Column to be a DataGridViewComboBoxColumn with ComboData from following query

DataTable dtComboData = getQueryResult ("SELECT DISTINCT Result FROM T_Result");

Is it possible?

Answer 1

You can use DataGridViewComboboxColumn for this approach. Below is a sample code to add a ComboboxColumn to DataGridView

Ex:-

        DataTable dtComboData = getQueryResult("SELECT DISTINCT Result FROM T_Result");
        DataGridViewComboBoxColumn col = new DataGridViewComboBoxColumn();
        col.DataSource = dtComboData;
        col.DisplayMember = dt.Columns[0].ColumnName;


        dgvResult.Columns.Add(col);
