[英]How to add to gridcontrol a new row at every click
I want to add new row to gridcontrol at every button click. 我想在每次单击按钮时向gridcontrol添加新行。 I tried many ways but no success.
我尝试了很多方法但没有成功。 I am sending my code.
我正在发送我的代码。
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();
}
You got to call 你得打电话
gridView1.DataBind();
after you set the DataSource 设置DataSource后
You can use the code below to add a new row in your GridControl : 您可以使用以下代码在GridControl中添加新行:
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);
}
You must change columns name and val1, val2, val3 with your values. 您必须使用您的值更改列名称和val1,val2,val3。
