Hello, You can use below code to fill Combobox on your form load even.
private void Form1_Load(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt = FillDT();
this.cmbTempControl.DataSource = dt;
this.cmbTempControl.ValueMember = "ID";
this.cmbTempControl.DisplayMember = "Name";
}
protected DataTable FillDataTable()
{
DataTable dtTemp = new DataTable();
/\*Write here code to Fill your Datatable form Database \*/
return dtTemp;
}
Thanks
