在我的 C# 应用程序中，我使用了一个datagridview，在这些网格中，我使用了一个网格事件，即单元格值更改，我在单元格值更改中使用了一些计算，现在在网格上输入数据时问题非常慢。
我该如何解决这些。？
在这里，我显示了我的网格单元格值更改事件代码：
private void dgvSalesInvoice_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
if (IsSetGridValueChange == true)
{
BatchSP spBatch = new BatchSP();
UnitConvertionSP spUnitConversion = new UnitConvertionSP();
DataTable dtblUnitConversion = new DataTable();
decimal decBatchId = 0;
string strBarcode = string.Empty;
try
{
if (e.RowIndex != -1 && e.ColumnIndex != -1)
{
if (dgvSalesInvoice.RowCount > 1)
{
if (dgvSalesInvoice.Columns[e.ColumnIndex].Name == "dgvtxtSalesInvoicembUnitName")
{
if (dgvSalesInvoice.Rows[e.RowIndex].Cells["dgvtxtSalesInvoicembUnitName"].Value != null && dgvSalesInvoice.Rows[e.RowIndex].Cells["dgvtxtSalesInvoicembUnitName"].Value.ToString() != string.Empty)
{
UnitConvertionSP SpUnitConvertion = new UnitConvertionSP();
DataTable dtblUnitByProduct = new DataTable();
dtblUnitByProduct = SpUnitConvertion.UnitConversionIdAndConRateViewallByProductId(dgvSalesInvoice.Rows[e.RowIndex].Cells["dgvtxtSalesInvoiceProductId"].Value.ToString());
foreach (DataRow drUnitByProduct in dtblUnitByProduct.Rows)
{
if (dgvSalesInvoice.Rows[e.RowIndex].Cells["dgvtxtSalesInvoicembUnitName"].Value.ToString() == drUnitByProduct.ItemArray[0].ToString())
{
dgvSalesInvoice.Rows[e.RowIndex].Cells["dgvtxtSalesInvoiceUnitConversionId"].Value = Convert.ToDecimal(drUnitByProduct.ItemArray[2].ToString());
dgvSalesInvoice.Rows[e.RowIndex].Cells["dgvtxtSalesInvoiceConversionRate"].Value = Convert.ToDecimal(drUnitByProduct.ItemArray[3].ToString());
decimal decNewConversionRate = Convert.ToDecimal(dgvSalesInvoice.Rows[e.RowIndex].Cells["dgvtxtSalesInvoiceConversionRate"].Value.ToString());
decimal decNewRate = (decCurrentRate * decCurrentConversionRate) / decNewConversionRate;
dgvSalesInvoice.Rows[e.RowIndex].Cells["dgvtxtSalesInvoiceRate"].Value = Math.Round(decNewRate, PublicVariables._inNoOfDecimalPlaces);
}
}
