Combobox

Hi Anil,

Place the combox control in your form.

Call the BindCombo() method to load and bind to the combo box control.
The id will be given as value and name will be given as display text.

Write the index changed event to the combo box to fire when you select the items in the combo.

private void cmbCustomers_SelectedIndexChanged(object sender, EventArgs e)

{

string CustomerID = cmbCustomers.SelectedValue.ToString();

}

private void BindCombo()

{

DataTable dt = new DataTable();

DataRow dRow;

DataColumn dColumn;

dColumn = new DataColumn();

dColumn.ColumnName = "CustomerID";

dColumn.AutoIncrement = true;

dColumn.AutoIncrementSeed = 1;

dColumn.AutoIncrementStep = 1;

dt.Columns.Add(dColumn);

dColumn = new DataColumn();

dColumn.ColumnName = "CustomerName";

dt.Columns.Add(dColumn);

dRow = dt.NewRow();

dRow["CustomerName"] = "Senthil";

dt.Rows.Add(dRow);

dRow = dt.NewRow();

dRow["CustomerName"] = "Kumar";

dt.Rows.Add(dRow);

dRow = dt.NewRow();

dRow["CustomerName"] = "Mahesh";

dt.Rows.Add(dRow);

cmbCustomers.DataSource = dt;

cmbCustomers.ValueMember = "CustomerID";

cmbCustomers.DisplayMember = "CustomerName";

}
