First create class : encrypt_decrypt.cs
inside:

using System;
using System.Security.Cryptography;
using System.Text;
 
namespace RestWebinarSample
{
 
    class Encryptor
    {
        public static string IV = "1a1a1a1a1a1a1a1a";
        public static string Key = "1a1a1a1a1a1a1a1a1a1a1a1a1a1a1a13";
 
        public static string Encrypt(string decrypted)
        {
            byte[] textbytes = ASCIIEncoding.ASCII.GetBytes(decrypted);
            AesCryptoServiceProvider endec = new AesCryptoServiceProvider();
            endec.BlockSize = 128;
            endec.KeySize = 256;
            endec.IV = ASCIIEncoding.ASCII.GetBytes(IV);
            endec.Key = ASCIIEncoding.ASCII.GetBytes(Key);
            endec.Padding = PaddingMode.PKCS7;
            endec.Mode = CipherMode.CBC;
            ICryptoTransform icrypt = endec.CreateEncryptor(endec.Key, endec.IV);
            byte[] enc = icrypt.TransformFinalBlock(textbytes, 0, textbytes.Length);
            icrypt.Dispose();
            return Convert.ToBase64String(enc);
        }
 
        public static string Decrypted(string encrypted)
        {
            byte[] textbytes = Convert.FromBase64String(encrypted);
            AesCryptoServiceProvider endec = new AesCryptoServiceProvider();
            endec.BlockSize = 128;

            endec.Padding = PaddingMode.PKCS7;
            endec.Mode = CipherMode.CBC;
            ICryptoTransform icrypt = endec.CreateDecryptor(endec.Key, endec.IV);

            icrypt.Dispose();
            return System.Text.ASCIIEncoding.ASCII.GetString(enc);
        }

}

then 2 buttons encrypt and decrypt

private void decrypt_Click(object sender, EventArgs e)
{
    StreamReader sr = new StreamReader(Application.StartupPath + "\\data\\" + "data.ls");
    string line = sr.ReadLine();
 
    MessageBox.Show(Encryptor.Decrypted(Convert.ToString(line)));
}

ASPXGRIDVIEW İşlemleri

On By semt20In C SHARP, DevexpressLeave a comment
Gridviewde seçili satırın bilgisini alabilme :
        protected void ASPxGridView1_SelectionChanged(object sender, EventArgs e)
        {
            var products = ASPxGridView1.GetSelectedFieldValues(“NAME”);
            Label1.Text = products[0].ToString();
        }

Gridviewin Sonuna İşlemler Seç eklemek için source da sona ekle
           
               
           
       
   

Gridview devexpress 7.2 sonrası için gecerli export Gridview
un altina ekle
 

un ustune ekle
        <Toolbars>
            <dx:GridViewToolbar EnableAdaptivity=“true”>
                <Items>
                    <dx:GridViewToolbarItem Command=“ExportToPdf” />

Gridview grup category combobox ve baglantisi 
birinci sqldatasource_musteriler yarat ve bunu aspxgridviewe bind
Ikinci datasource sqldatasource_musterigruplari  yarat  bu bir yere bind olmayacak

Sqlden iki tablo yarat birinin adi musteri(id,adi,grupid) olsun
digeride musteri_grup (id,grup_adi) olsun

aspxgridview designerda columnsa tikla combobox column ekle captionunu grup yap, Fieldname grupid sec, sag tabda comboboxpropertiesde datasourceid musteri_gruplarini sec text field grup_adi , valuefield=id 


Gridview Horizontal scrollbar 

   

       

       

       

Datasource eklemede hata alırsan sol taraftan server explorerden modify deyip save passwordu seç


Gridview  Required zorunlu alan ayari
Designerda ac ve columnsdan zorunlu alana tıkla ve sağda textboxpropertiesden en aşağıda validation settingste requiredi true yap

Master Detail Grid
ONCE 2 TANE SQLDATASOURCE VE 2 TANE ASPXGRIDVIEW YARAT BIRI MUSTERILER DIGERI MUSTERI HAREKETLER
MUSTERILERI NORMAL TABLODAN AL ASPXGRIDVIEW MUSTERILERIN SETTINGS DETAILDE DETAILROWU TRUE YAP,

MUSTERI HAREKETLERINIDE AL WHERE KISMINA TIKLA COLUMN MUSTERI_ID OPERATOR ” = ”  , SOURCE SESSION , SESSION FIELD = MUSTERI_ID

VE DAHA SONRA KODA EKLE
        protected void ASPxGridViewmusterihareketler_BeforePerformDataSelect(object sender, EventArgs e)
        {
            Session[“MUSTERI_ID”] = (sender as ASPxGridView).GetMasterRowKeyValue();
        }

SON OLARAKDA ASPXGRIDVIEWMUSTERILERE TIKLA EDITTEMPLATE VE DETAILROWU SEC VE ASPXGRIDMUSTERIHAREKETLERINI ICINE SURUKLE VE END TEMPLATE YAP


Gridviewda son kolumun genişliğini max yapmak
       
           
           
           
               
           
            <dx:GridViewDataTextColumn FieldName="ADI" VisibleIndex="2" Width=”100%”>
           
       


gridview detay masterda detay width sorunu once masterin altina ekle :
    <dx:ASPxGridView Width=”100%” 
       
       

sonra masterin son colomunun widthini %100 yap
 

sonra detaya ekle
   <dx:ASPxGridView2 Width=”100%”
