Binding to Specific Datagridview Columns That I Create in Code

Hello all. Before I get into it, I will show my code.

public struct KEYTABLES
    {
        public string TableName;
        public int MaxInterval;

    }

public class KeyTableXML
    {
        public string m_TableName;
        public int m_Interval;

        public KeyTableXML(string tn, int interval)
        {
            m_TableName = tn;
            m_Interval = interval;
        }

        public string KeyTable
        {
            get { return m_TableName; }
        }

        public int Interval
        {
            get { return m_Interval; }
        }
    }

public class KTXML
    {
        private List<KeyTableXML> m_KTxml;
        public KTXML(List<KEYTABLES> kt)
        {
            m_KTxml = new List<KeyTableXML>();

            foreach (KEYTABLES k in kt)
            {
                KeyTableXML ktxml = new KeyTableXML(k.TableName, k.MaxInterval);
                m_KTxml.Add(ktxml);
            }
        }

        public List<KeyTableXML> GetData()
        {
            return m_KTxml;
        }
    }

        private void LoaddgKeyTables()
        {
            // Bind the BindingSource to the DataGridView
            // control's DataSource.
            this.dgKeyTables.DataSource =
                this.bindingSource1;
            KTXML x = new KTXML(KeyTables);
            bindingSource1.DataSource = x.GetData();


            DataGridViewComboBoxColumn col0 = new DataGridViewComboBoxColumn();
            col0.HeaderText = "Table Name";

            foreach (string table in AllInitialDBTables)
            {
                col0.Items.Add(table);
            }

            dgKeyTables.Columns.Add(col0);

            DataGridViewTextBoxColumn col = new DataGridViewTextBoxColumn();
            col.HeaderText = "Interval";
            dgKeyTables.Columns.Add(col);

            // Add a DemoCustomer to cause a row to be displayed.
            this.bindingSource1.AddNew();
        }

My goal is to have a DataGridView with 2 columns.

Column 1 should be a listbox column that displays TableName. The listbox itself shows all available tables from List<KeyTable>. The listbox is being populate correctly from the foreach loop.

Column 2 should be a textbox column that displays the Interval.

What I get with this code is a datagrid with 4 columns. I get a the 2 bound columns that are plain text boxes that show the proper values. Then I get the 2 columns that I created in code that show nothing. The Table column is a listbox and the listbox is populated with table names.

Can someone help me figure out what I am doing wrong? I want the datagrid columns that I create in code to show the data from the binding source. I have tried binding the datagrid to the binding source before I create the columns, and after I create the columns.

Thanks,

David

I figured it out and wanted to show the solution. I found the solution from http://stackoverflow.com/questions/2648921/c-adding-columns-to-bound-datagridview-with-code

private void LoaddgKeyTables()
        {
            DataGridViewComboBoxColumn col0 = new DataGridViewComboBoxColumn();
            col0.HeaderText = "Table Name";

            foreach (string table in AllInitialDBTables)
            {
                col0.Items.Add(table);
            }
            col0.DataPropertyName = "KeyTable";
            dgKeyTables.Columns.Add(col0);

            DataGridViewTextBoxColumn col = new DataGridViewTextBoxColumn();
            col.HeaderText = "Interval";
            col.DataPropertyName = "Interval";
            dgKeyTables.Columns.Add(col);

            dgKeyTables.AutoGenerateColumns = false;
            // Bind the BindingSource to the DataGridView
            // control's DataSource.
            this.dgKeyTables.DataSource =
                this.bindingSource1;
            KTXML x = new KTXML(KeyTables);
            bindingSource1.DataSource = x.GetData();

            // Add a DemoCustomer to cause a row to be displayed.
            //this.bindingSource1.AddNew();
        }

I needed to add the DataPropertyName to each column that I built. This is how the datagridview columns get associated with a field in the binding source.
