我想找到另一種正確的方法來檢索圖片或圖像從XtragridControl gridview中的選定行到窗體中的圖片框。如何從選定的GridView行中檢索圖像
這是場景。
我有多個按鈕功能區控制，第一個按鈕打開客戶數據，在那裏你會發現有2個按鈕第一按鈕，打開客戶表單添加新客戶，第二個按鈕的用戶控件打開編輯客戶表格在從電網選擇特定客戶後，您可以在其中編輯客戶，我想要一個更簡單的方法，可以讓我檢索客戶的圖像或照片以及所有其他信息。
找到我的代碼示例如下：
// this my class Holding Field from table in database
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Drawing;
namespace YoungWoman
{
public static class GetRowData
{
public static int LesseeId;
public static byte image; //
public static string LesseeName;
public static string LesseeLastName;
public static string PassportNo;
public static string IDNo;
public static DateTime BirthDate;
public static string Gender;
public static string Country;
public static string City;
public static string Province;
public static string LesseePostalCode;
public static string MobileNo;
public static string HomePhoneNo;
public static string TutorName;
public static string TutorLastName;
public static string AddressTutor;
public static string AddressLessee;
public static string TutorPhoneNo;
public static string TutorEmail;
}
}
// this user control containing the XtragridControl and how i retrieve values from the grid to get the form populated
private void EditLesseeFrm_Click(object sender, EventArgs e)
{
Lesseefrm Lessee = new Lesseefrm(Utils.Formtype.edit, 1);
Lessee.LesseeEventHandler += new EventHandler(RefreshLesseeGrid);
Lessee.RefreshLabeslEvent += new EventHandler(RefreshingLabels);
GetRowData.LesseeId = Convert.ToInt32(gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "LesseeId"));
//GetRowData.LesseePic = ByteImageConve(gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "LesseePic")); // this line of code return an error

GetRowData.TutorLastName = Convert.ToString(gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "TutorLastName"));
GetRowData.TutorPhoneNo = Convert.ToString(gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "TutorPhoneNo"));
GetRowData.TutorEmail = Convert.ToString(gridView1.GetRowCellValue(gridView1.FocusedRowHandle, "TutorEmail"));
Lessee.ShowDialog();
}
// this the form to receive the values from the grid to update
if (formtype == Formtype.edit && Lesseeid > 0)
{
LesseeIdtextEdit.Enabled = false;
ClearBtnlayoutControlItem26.Visibility = DevExpress.XtraLayout.Utils.LayoutVisibility.Never;
SaveBtn.Text = "&Edit";
SaveBtn.Image = Resources.brush_16;
this.Text = string.Format(" Edit Lessee Information - YW Residence ");
LesseeIdtextEdit.Text = Convert.ToInt32(GetRowData.LesseeId).ToString();
txtName.Text = GetRowData.LesseeName;
txtLAstname.Text = GetRowData.LesseeLastName;
txtPassport.Text = GetRowData.PassportNo;
txtID.Text = GetRowData.IDNo;
GendercomboBoxEdit.SelectedItem = GetRowData.Gender;
DobdateEdit.DateTime = GetRowData.BirthDate;
CountrycomboBoxEdit.SelectedItem = GetRowData.Country;
txtProvince.Text = GetRowData.Province;
txtCity.Text = GetRowData.City;
txtPostalCode.Text = GetRowData.LesseePostalCode;
LesseememoEdit1.Text = GetRowData.AddressLessee;
txtMobile.Text = GetRowData.MobileNo;
txtHomePhone.Text = GetRowData.HomePhoneNo;
txtTutorName.Text = GetRowData.TutorName;
txttutorLastname.Text = GetRowData.TutorLastName;
tutorAddresstxt.Text = GetRowData.AddressTutor;
txtTutorMobile.Text = GetRowData.TutorPhoneNo;
txtEmail.Text = GetRowData.TutorEmail;
}
and this how i save before proceeding to any update
