With a .Net 2's WinForms which contain
1) a DataGrid which is assigned to a DataSet's DataTable (some columnsare
"hidden" on screen)
2) a few TextBox which are aligned to different fields within the same
DataTable
What event do I code for the .Net DataGrid such that the TextBoxes's value
are updated as different rows are selected?
Hi Patrick,
Use DataBinding for this. Bind the Text property of the TextBox to the Column you want to display. The code below demonstrates how to do this.
DataGridView dataGridView1 = new DataGridView();
TextBox textBox1 = new TextBox();
protected override void OnLoad(EventArgs e)
{
this.Controls.Add(dataGridView1);
this.Controls.Add(textBox1);
textBox1.Location = new Point(dataGridView1.Width + 5, 0);
DataSet set = new DataSet();
set.Tables.Add(new DataTable());
set.Tables[0].Columns.Add("ID", typeof(System.Int32));
set.Tables[0].Columns.Add("Value", typeof(System.String));
DataRow row = set.Tables[0].NewRow();
row["ID"] = 1;
row["Value"] = "One";
set.Tables[0].Rows.Add(row);
row = set.Tables[0].NewRow();
row["ID"] = 2;
row["Value"] = "Two";
set.Tables[0].Rows.Add(row);
row = set.Tables[0].NewRow();
row["ID"] = 3;
row["Value"] = "Three";
set.Tables[0].Rows.Add(row);
dataGridView1.DataSource = set.Tables[0];
dataGridView1.Columns[0].Visible = false;
textBox1.DataBindings.Add("Text", set.Tables[0], "ID");
}
