如何在每次點擊時向gridcontrol添加新行

Question

我想在每次點擊按鈕時將新行添加到gridcontrol。我嘗試了很多方法，但沒有成功。我正在發送我的代碼。

private void B_Click(object sender, EventArgs e) 
     { 
    Button bt = (Button)sender; 
     int productId = (int)bt.Tag; 
     AddProductDataContext db = new AddProductDataContext(); 
     decimal Quantity; 
     decimal.TryParse(txtCalculator.Text, out Quantity); 
    var results = from inv in db.Inventories 
              where inv.RecId == productId 
              select new 
              { 
               inventoryName = inv.InventoryName, 
               Quantity, 
               Total = Quantity * inv.InventoryPrice 
              }; 

       DataTable dt = new DataTable(); 
       dt.Columns.Add("inventoryName"); 
       dt.Columns.Add("Quantity"); 
       dt.Columns.Add("Total"); 

       foreach (var x in results) 
       { 
        DataRow newRow = dt.Rows.Add(); 
        newRow.SetField("inventoryName", x.inventoryName); 
        newRow.SetField("Quantity", x.Quantity); 

        newRow.SetField("Total", x.Total); 

       } 

       gridControl1.DataSource = dt; 
       gridView1.AddNewRow(); 
} 

Answer 1

你得叫

gridView1.DataBind(); 

後你設置DataSource

Answer 2

您可以使用下面的代碼在你的GridControl添加新行：

gridView1.AddNewRow(); 

int rowHandle = gridView1.GetRowHandle(gridView1.DataRowCount); 
if (gridView1.IsNewItemRow(rowHandle)) 
{ 
    gridView1.SetRowCellValue(rowHandle, gridView1.Columns["ColumnName1"], val1); 
    gridView1.SetRowCellValue(rowHandle, gridView1.Columns["ColumnName2"], val2); 
    gridView1.SetRowCellValue(rowHandle, gridView1.Columns["ColumnName3"], val3); 
} 

你必須用您的值更改列名稱和val1，val2，val3。
