私は 2 つのページを持っています。ページ 1 には が含まれてgridviewおりlinkbutton、ID を別のページ (ページ 2) に渡すページを作成しました。2 ページ目には 10 個textboxの es があり、情報を編集するためのボタンが 1 つあります。
このコードはページ 1 用です:
...
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lbNextPage" runat="server"
PostBackUrl='<%# "~/secure/upst.aspx?id="+ Eval("ID_st") %>'>edit</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
...
これはページ 2 のコードです。
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
txtID.Text = Request.QueryString["id"].ToString();
}
SqlConnection con = new SqlConnection(strcon);
string query = "select * from user_st where ID_st = @id";
SqlCommand cmd = new SqlCommand(query, con);
cmd.Parameters.AddWithValue("@id", stid);
con.Open();
SqlDataReader dr = cmd.ExecuteReader();
dr.Read();
txtName.Text = dr["name"].ToString();
txtFamily.Text = dr["family"].ToString();
txtAddress.Text = dr["adres"].ToString();
txtHomeTel.Text = dr["home_tel"].ToString();
txtTahsilat.Text = dr["tahsilat"].ToString();
txtTel.Text = dr["celphone"].ToString();
txtEmail.Text = dr["email"].ToString();
txtShoghl.Text = dr["shoghl"].ToString();
txtAge.Text = dr["age"].ToString();
txtFadername.Text = dr["fader_name"].ToString();
txtIDnumber.Text = dr["melli_code"].ToString();
txtShSh.Text = dr["sh_sh"].ToString();
}
protected void btnOk_Click(object sender, EventArgs e)
{
Boolean res = false;
SqlConnection conn = new SqlConnection(strcon);
string famil = txtFamily.Text;
string name = txtName.Text;
string fader = txtFadername.Text;
string tahsil = txtTahsilat.Text;
Double telhome = Convert.ToDouble(txtHomeTel.Text);
string adres = txtAddress.Text;
Double cel = Convert.ToDouble(txtTel.Text);
string email = txtEmail.Text;
Double shsh = Convert.ToDouble(txtIDnumber.Text);
string shoghl = txtShoghl.Text;
int age = Convert.ToInt32(txtAge.Text);
Double melli = Convert.ToDouble(txtIDnumber.Text);
int id = Convert.ToInt32(txtID.Text);
string query = "update user_st set name=@name ,fader_name=@fader ,family=@famil,tahsilat=@tahsil,adres=@adres,home_tel=@telhome,celphone=@cel,email=@email ,sh_sh=@shsh,shoghl=@shoghl,age=@age,melli_code=@melli where ID_st=@id";
SqlCommand cmdup = new SqlCommand(query, conn);
cmdup.Parameters.AddWithValue("@name",name);
cmdup.Parameters.AddWithValue("@fader_name",fader );
cmdup.Parameters.AddWithValue("@family", famil);
cmdup.Parameters.AddWithValue("@tahsilat",tahsil);
cmdup.Parameters.AddWithValue("@adres", adres);
cmdup.Parameters.AddWithValue("home_tel",telhome );
cmdup.Parameters.AddWithValue("@celphone",cel );
cmdup.Parameters.AddWithValue("@email", email);
cmdup.Parameters.AddWithValue("@sh_sh", shsh);
cmdup.Parameters.AddWithValue("@shoghl", shoghl);
cmdup.Parameters.AddWithValue("@age",age );
cmdup.Parameters.AddWithValue("@melli_code", melli);
cmdup.Parameters.AddWithValue("@id", id);
try
{
conn.Open();
cmdup.ExecuteNonQuery();
conn.Close();
res = true;
}
catch (SqlException ex)
{
lblRes.Text = "error" + ex.ToString();
}
if (res)
{
lblResult.Text = "Ok";
}
それはうまくいかないので、私はこれを試しました：
//cmdup.Parameters.Add("@name", SqlDbType.NVarChar, 50).Value = txtName.Text;
//cmdup.Parameters.Add("@fader_name", SqlDbType.NVarChar, 50).Value = txtFadername.Text;
//cmdup.Parameters.Add("@family", SqlDbType.NVarChar, 50).Value = txtFamily.Text;
//cmdup.Parameters.Add("@tahsilat", SqlDbType.NVarChar, 50).Value = txtTahsilat.Text;
//cmdup.Parameters.Add("@adres", SqlDbType.NVarChar, 150).Value = txtAddress.Text;
//cmdup.Parameters.Add("home_tel", SqlDbType.Char, 10).Value = txtHomeTel.Text;
//cmdup.Parameters.Add("@celphone", SqlDbType.Char, 10).Value = txtTel.Text;
//cmdup.Parameters.Add("@email", SqlDbType.VarChar).Value = txtEmail.Text;
//cmdup.Parameters.Add("@sh_sh", SqlDbType.Char, 10).Value = txtShSh.Text;
//cmdup.Parameters.Add("@shoghl", SqlDbType.NVarChar, 50).Value = txtShoghl.Text;
//cmdup.Parameters.Add("@age", SqlDbType.Int).Value = txtAge.Text;
//cmdup.Parameters.Add("@melli_code", SqlDbType.Char, 10).Value = txtIDnumber.Text;
//cmdup.Parameters.Add("@id", SqlDbType.Int).Value = txtID.Text;
またはこれ：
//SqlCommand cmdup = new SqlCommand("EXEC up_st'" + txtName.Text. + "' , '" + txtFamily.Text + "' , '" + txtTahsilat.Text +"' , '" + txtAddress.Text + "' , '"
// + txtHomeTel.Text + "' , '" + txtTel.Text + "' , '" + txtEmail.Text + "' , '" + txtShoghl.Text + "' , '"
// + txtAge.Text + "' , '" + txtFadername.Text + "' , '" + txtIDnumber.Text + "' , '" + txtShSh.Text + "' , '"
// + txtID.Text + "'", conn);
またはこれ：
/*"update user_st set name='" + txtName.Text + "',fader_name='" + txtFadername.Text + "',family='" + txtFamily.Text + "',tahsilat='" + txtTahsilat.Text + "',adres='" + txtAddress.Text + "',home_tel='" + txtHomeTel.Text + "',celphone='"
+ txtTel.Text + "',email='" + txtEmail.Text + "',sh_sh='" + txtShSh.Text + "',shoghl='" + txtShoghl.Text + "',age='" + txtAge.Text + "',melli_code='" + txtIDnumber.Text + "' where ID_st=" + txtID.Text*/
しかし、それも機能しません。
