Checkbox in DataGridView
 

Hello,
I am having an issue trying to add a checkbox field to my DataGrid. I have the following Code but it does not display my checkbox. Any help is greatly appreciated.

        Dim myconnection1 As New SqlConnection(myconn)

        Dim dtcCheck As New DataColumn("Select")

        dtcCheck.DataType = System.Type.GetType("System.Boolean")

        dtcCheck.DefaultValue = False

        Dim sa As New SqlDataAdapter("SELECT * FROM therapy", myconnection1)

        sa.Fill(ds, "Therapy")

        DataGridView1.DataSource = ds.Tables("Therapy")

        ds.Tables.Add.Columns.Add(dtcCheck)

Thank You

Re: Checkbox in DataGridView
 

I used this code to create a table with each month as a checkbox

        Dim chkBox As System.Type = System.Type.GetType("System.Boolean")

        With dtYear.Columns

            .Add("Jan", chkBox)

            .Add("Feb", chkBox)

            .Add("Mar", chkBox)

            .Add("Apr", chkBox)

            .Add("May", chkBox)

            .Add("Jun", chkBox)

            .Add("Jul", chkBox)

            .Add("Aug", chkBox)

            .Add("Sep", chkBox)

            .Add("Oct", chkBox)

            .Add("Nov", chkBox)

            .Add("Dec", chkBox)

        End With
