Inserting a checkbox column

it seems really difficult to use C1TrueDBGrid at first but as you learn new things it looks easier day by day.... there are two ways to add checkbox column in a bound grid one to add the check box column in database or add in the dataset after getting values from database. Following code adds a checkbox column at the start of the table in dataset and then sets a checkbox column in c1TrueDBGrid1

//Code to connect to database
DbAdapter.Fill(dataSet1, tblName);
 dataSet1.Tables[0].Columns.Add("check_box", typeof(bool));
 dataSet1.Tables[0].Columns["check_box"].SetOrdinal(0);
                 
 c1TrueDBGrid1.DataSource = dataSet1.Tables[0];
//rest of the code for column setting
//code for checkbox column setting
 C1.Win.C1TrueDBGrid.ValueItemCollection check1 = c1TrueDBGrid1.Columns["Check_box"].ValueItems.Values;
c1TrueDBGrid1.Columns["Check_box"].ValueItems.Translate = true;
c1TrueDBGrid1.Columns["Check_box"].ValueItems.Presentation = C1.Win.C1TrueDBGrid.PresentationEnum.CheckBox;
check1.Add(new C1.Win.C1TrueDBGrid.ValueItem("0", false));
 check1.Add(new C1.Win.C1TrueDBGrid.ValueItem("1", true));
//CheckBox Column Presentation
c1TrueDBGrid1.Splits[0].DisplayColumns["check_box"].Width = 20;
c1TrueDBGrid1.Splits[0].DisplayColumns["check_box"].Frozen = true;
c1TrueDBGrid1.Splits[0].DisplayColumns["check_box"].Locked = false;
c1TrueDBGrid1.Columns["check_box"].Caption = "";
