    <p>I have been working on an issue for a while and I finally figured it out. I was trying to set a control when the Form is being initialize. I am thinking that the control's value isn't being set is because the control has been drawn yet (CORRECT ME IF I AM WRONG). </p> <p>My partial form code</p> <pre><code>//in form 1 .... private void button2_Click(object sender, EventArgs e) { Form2 form = new Form2(); form.Owner = this; form.Show(this); } ....} public Form2() { InitializeComponent(); setData(); //Sets a datagridview's combobox column and databinds a datatable setGrid(); //Sets each row in the datagridview combobox's value to a string } private void setData() { gvTest.AllowUserToAddRows = false; string strConn = "server=10.253.3.185;database=petersun-test1;user id=ctore;password=cqi$$;connection timeout=30"; SqlConnection conn = new SqlConnection(strConn); DataTable dit = new DataTable(); try { conn.Open(); string sql = "SELECT LTRIM(RTRIM(COLUMN_NAME)) as ColumnName from INFORMATION_SCHEMA.COLUMNS where Table_Name='coproc' order by ORDINAL_POSITION"; SqlCommand cmd = new SqlCommand(sql, conn); SqlDataAdapter da = new SqlDataAdapter(cmd); da.Fill(dit); DataGridViewComboBoxColumn dcDatabasefields = new DataGridViewComboBoxColumn(); dcDatabasefields.DataPropertyName = "ColumnName"; dcDatabasefields.HeaderText = "Database Field Name"; dcDatabasefields.Name = "dbFields"; dcDatabasefields.DisplayMember = "ColumnName"; dcDatabasefields.ValueMember = "ColumnName"; dcDatabasefields.Width = 200; BindingSource bsourceFields = new BindingSource(); bsourceFields.DataSource = dit; dcDatabasefields.DataSource = bsourceFields; dcDatabasefields.DataSource = dit; // bsourceFields; gvTest.Columns.Add(dcDatabasefields); } finally { conn.Close(); } DataTable dt = new DataTable(); DataColumn dc = new DataColumn("options"); dt.Columns.Add(dc); DataRow dr = dt.NewRow(); dr["options"] = "A"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["options"] = "C"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["options"] = "D"; dt.Rows.Add(dr); dr = dt.NewRow(); dr["options"] = "E"; dt.Rows.Add(dr); gvTest.DataSource = dt; } private void setGrid() { foreach(DataGridView Row in gvGrid.Rows) { Row.Cells[0].Value = "string"; } } </code></pre> <p>So what I think is happening is: 1. The component is getting initialized 2. Creates the datagridview with columns 3. Sets the column values 4. Draws the form</p> <p>Is my thinking correct? My question is what form event should I set the control's value? I did some research and I am thinking on the PAINT event, but I am not sure either. Could someone explain the Form's life cycle in some detail or point me to somewhere. Thanks</p>

    1. COAre you referring to setting properties of the control with variables like height/width, or adding data to be displayed by the control?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
