[英]C# - Get the sum of the total amount of width for each column in datagridview
[英]total amount of the entire column in Datagridview passing to a textbox in c#
如何以相同的形式將datagridview中的總金額發送到文本框?
// this part is calculating the total amount of a row
private void SalesDataGrid_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
if (SalesDataGrid != null)
{
for (int x = 0; x < SalesDataGrid.Rows.Count; x++)
{
SalesDataGrid.Rows[x].Cells[3].Value = Convert.ToInt32(SalesDataGrid.Rows[x].Cells[1].Value) *
Convert.ToDouble(SalesDataGrid.Rows[x].Cells[2].Value);
//and i've tried this one below if it will work but it didn't do anything
}
if (SalesDataGrid != null)
{
for (int x = 0; x < SalesDataGrid.Rows.Count; x++)
{
txtsalestotal.Text = SalesDataGrid.Rows[x].Cells[3].Value.ToString() ;
}
}
嘗試這個:
double totalAmount=0;
for (int x = 0; x < SalesDataGrid.Rows.Count; x++)
{
totalAmount += Convert.ToDouble(SalesDataGrid.Rows[x].Cells[3].Value.ToString());
}
txtsalestotal.Text=totalAmount.ToString();
