ขอบคุณค่ะ เขียนได้แล้ว แสดงผลดังภาพค่ะ
Code (C#)
private void Binddata()
{
eContractDBDataContext db = new eContractDBDataContext();
var chkMeal = from ml in db.Mealzs
where ml.PropID == Request.QueryString["HotelID"].ToString().ToDecimal()
where ml.ValidID == Request.QueryString["V"].ToString().ToDecimal()
where ml.CurrencyID == Request.QueryString["cur"].ToString().ToDecimal()
select ml;
if (chkMeal.ToList().Count > 0)
{
for (int i = 0; i < grdSearch.Rows.Count; i++)
{
TextBox txtMealPrice1 = new TextBox();
txtMealPrice1 = grdSearch.Rows[i].FindControl("txtMealPrice1") as TextBox;
txtMealPrice1.ReadOnly = false;
TextBox txtMealPrice2 = new TextBox();
txtMealPrice2 = grdSearch.Rows[i].FindControl("txtMealPrice2") as TextBox;
txtMealPrice2.ReadOnly = false;
TextBox txtMealPrice3 = new TextBox();
txtMealPrice3 = grdSearch.Rows[i].FindControl("txtMealPrice3") as TextBox;
txtMealPrice3.ReadOnly = false;
foreach (var item in chkMeal)
{
if (grdSearch.DataKeys[i].Value.ToString().ToDecimal() == item.MealTypeID)
{
if (item.AgeID == 33)
{
txtMealPrice1.Text = item.MealPrice.ToString();
}
if (item.AgeID == 34)
{
txtMealPrice2.Text = item.MealPrice.ToString();
}
if (item.AgeID == 36)
{
txtMealPrice3.Text = item.MealPrice.ToString();
}
if (Request.QueryString["mode"] != null)
{
CheckBox chkUse = new CheckBox();
chkUse = grdSearch.Rows[i].FindControl("chkUse") as CheckBox;
chkUse.Checked = true;
chkUse.Enabled = false;
txtMealPrice1.ReadOnly = true;
txtMealPrice2.ReadOnly = true;
txtMealPrice3.ReadOnly = true;
cmdSave.Visible = false;
cmdUpdate.Visible = true;
}
}
}
}
}
}
แล้วถ้าทำการเพิ่มข้อมูลแล้วคลิกupdate เขียนแบบนี้ถูกหรือป่าวคะ
Code (C#)
protected void cmdUpdate_Click(object sender, EventArgs e)
{
eContractDBDataContext db = new eContractDBDataContext();
int icount = 0;

chkUse.Enabled = false;
if (chkUse.Checked == true)
{
CheckBox chkAdult = new CheckBox();
chkAdult = grdSearch.Rows[i].FindControl("chkAdult") as CheckBox;
CheckBox chkTeen = new CheckBox();
chkTeen = grdSearch.Rows[i].FindControl("chkTeen") as CheckBox;
CheckBox chkChild = new CheckBox();
chkChild = grdSearch.Rows[i].FindControl("chkChild") as CheckBox;
TextBox txtMealPrice1 = new TextBox();
txtMealPrice1 = grdSearch.Rows[i].FindControl("txtMealPrice1") as TextBox;
