如何將多行從GridView Winform Devexpress存儲到Access數據庫？

Question

如何將多行從GridView存儲到Access數據庫。我有代碼存儲單聚焦行，但我需要存儲多行？如何完成我的任務？

這段代碼我用來存儲單一集中的一行單列

OleDbConnection conn = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=D:/Srihari/Samples.accdb"); 
      conn.Open(); 



      string s1 = (string)gridView1.GetFocusedRowCellValue("Item"); 
      string s2 = (string)gridView1.GetFocusedRowCellValue("Description"); 
      string s3 = (string)gridView1.GetFocusedRowCellValue("UoM"); 
      object quant = gridView1.GetFocusedRowCellValue("Quantity"); 
      object price = gridView1.GetFocusedRowCellValue("Price"); 
      object taxp = gridView1.GetFocusedRowCellValue("Tax in Percentage"); 
      object taxa = gridView1.GetFocusedRowCellValue("Tax in Amount"); 
      object total = gridView1.GetFocusedRowCellValue("Total"); 


      int a = Convert.ToInt32(quant); 
      int b = Convert.ToInt32(price); 
      int c = Convert.ToInt32(taxp); 
      int d = Convert.ToInt32(taxa); 
      int e = Convert.ToInt32(total); 


       OleDbCommand cmd = new OleDbCommand("insert into gridview(Item,Description,UoM,Quantity,Price,TaxinPercentage,TaxinAmount,Total) values ('" + s1 + "','" + s2 + "','" + s3 + "', " + a + " , " + b + " , " + c + " , " + d + " , " + e + ")", conn); 
       cmd.ExecuteNonQuery(); 
       MessageBox.Show("Inserted Successful","Information",MessageBoxButtons.OK,MessageBoxIcon.Information); 
       Close(); 

此代碼的工作，但我需要存儲多行，請幫助我。

在此先感謝。

要獲取所有選定的行，請使用GridView GetSelectedRows方法。閱讀文檔以瞭解有關此功能的更多信息。

以下是您可以遵循的方式。您可以從xtragrid中獲取多個選定的行，如下所示。

int[] selRows = ((GridView)gridControl1.MainView).GetSelectedRows(); 
DataRowView selRow = (DataRowView)(((GridView)gridControl1.MainView).GetRow(selRows[0])); 
txtName.Text = selRow["name"].ToString(); 

這裏是讓你做Multiple selection using checkbox (web style)

示例代碼片段

using DevExpress.XtraGrid.Views.Base; 

ColumnView View = gridControl1.MainView as ColumnView; 
View.BeginUpdate(); 
try { 
    int rowHandle = 0; 
    DevExpress.XtraGrid.Columns.GridColumn col = View.Columns["Category"]; 
    while(true) { 
     // locating the next row 
     rowHandle = View.LocateByValue(rowHandle, col, "SPORTS"); 
     // exiting the loop if no row is found 
     if (rowHandle == DevExpress.XtraGrid.GridControl.InvalidRowHandle) 
     break; 
     // perform specific operations on the row found here 
     // ... 
     rowHandle++; 
    } 
} finally { View.EndUpdate(); }
