Updating Data via DataGrid comboBox`

Hey Rohan,

thanks for getting back to me but I thought that I posted this underneath the C# area.  Wouldn't be the first time I posted a question in the wrong section.  Sounds to me like ASP.Net stuff.  Do you know how to do this w/o using ASP.Net?

Also,  for my comboBox I have set the DisplayMember and the ValueMember as well.  Is there an event that traps when a user moves away from a certain column.  For example, a user changes a combobox value from "Option1" to "Option3" and then click away from that column.  I would like to capture that event and my ValueMember as well.

Thank you in advance

Hi,

What language are you using for development. For combobox ..u can use OnChange Event ...You can write this in java script. The onChange event gets fired when u make a different selection in combobox so if option 1 is listed and u click option 3 then this event gets fired but if u drop down the box and make the same selection its not a change so u if u keep selecting same value the event wont fire which is perfectly right.

If you give more specifics .. i will paste some code if you want.

Hey Rohan,

I am attempting to use C# anyways :)  Still at the beginning stages of learning.  Below is the method that does the heavy lifting.  

private void MakeDataSetAndBindGrid()
{
      string connString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\\Documents and Settings\\toll\\My Documents\\Current Projects\\LibraryStatus\\LibraryStatus.mdb;Persist Security Info = False";

      string sqlString = "SELECT * FROM NESingles";

      dataAdapter = null;
      myDataSet = null;

      try
      {
            connection = new OleDbConnection(connString);

            dataAdapter = new OleDbDataAdapter(sqlString, connection);
            myDataSet = new DataSet();
            dataAdapter.Fill(myDataSet, "NESingles");

            sqlString = "SELECT Status_ID, Status FROM Statuses";

            dataAdapter = new OleDbDataAdapter(sqlString, connection);
            dataAdapter.Fill(myDataSet, "Statuses");

            //connection.Close();
      }
      catch (Exception ex)
      {
            MessageBox.Show("Problem with DB access-\n\n connection: "
            + connString + "\r\n\r\n                      query: " + sqlString
            + "\r\n\r\n\r\n" + ex.ToString());

            this.Close();
            return;
      }

      DataGridTableStyle tableStyle = new DataGridTableStyle();
      tableStyle.MappingName = "NESingles";

      DataTable dt = myDataSet.Tables["NESingles"];

      for(int i = 0; i < dt.Columns.Count; ++i)
      {
            if(i != 8)
            {
                  DataGridTextBoxColumn textCol = new DataGridTextBoxColumn();
                  textCol.MappingName = dt.Columns[i].ColumnName;
                  textCol.HeaderText = dt.Columns[i].ColumnName;
                  tableStyle.GridColumnStyles.Add(textCol);
            }
            else
            {
                  DataGridComboBoxColumn comboTextCol = new DataGridComboBoxColumn();
                  comboTextCol.MappingName = "Status_FK";

                  comboTextCol.HeaderText = "myStatus";
                  comboTextCol.Width = 120;
                  comboTextCol.ColumnComboBox.DataSource = myDataSet.Tables["Statuses"].DefaultView;
                  comboTextCol.ColumnComboBox.DisplayMember = "Status";
                  comboTextCol.ColumnComboBox.ValueMember = "Status_ID";

                  tableStyle.PreferredRowHeight = comboTextCol.ColumnComboBox.Height + 2;

                  tableStyle.GridColumnStyles.Add(comboTextCol);
            }
      }

      dgStatus.TableStyles.Clear();
      dgStatus.TableStyles.Add(tableStyle);
      dgStatus.DataSource = dt;
}

Hey Rohan, in the event that you are still working on this question....i want to let you know that i am deleting this question.  i appreciate your comments.  turns out that i set the datasource to a datatable and i should have set it to a dataset.

thanks
