Sir, This is a VB code, I want C# code
please send the c# code to write in :-

 private void dgvPurchaseDetails_DataError(object sender, DataGridViewDataErrorEventArgs e)
 {
            
 }

Private Sub DataGridView1_DataError(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewDataErrorEventArgs) Handles DataGridView1.DataError

See , I getting error in form_Load event

My Stored procedure:-

ALTER PROCEDURE purchaseDetailsGridviewAll
AS

SELECT  purchaseinvoiceNo, puchaseDate, voucherNo, purchaseId, venderName, grandTotal
FROM  tbl_PurchaseDetails 




My SP Class code

public void purchaseDetailsGridviewAll()
  {
  DataTable d = new DataTable();
  d.Columns.Add("SINo", typeof(int));
  d.Columns["SINo"].AutoIncrement = true;
  d.Columns["SINo"].AutoIncrementSeed = 1;
  d.Columns["SINo"].AutoIncrementStep = 1;
  purchaseSp spPurchase = new purchaseSp();
  d = spPurchase.purchaseDetailsGridviewAll();
  dgvPurchaseDetails.DataSource = d;

  }


and My frm.cs code:-

 purchaseSp spPurchase = new purchaseSp();
  decimal decA = spPurchase.RegisterCount();
  purchaseDetailsGridviewAll();
  txtvoucherNo.Text = decA.ToString();
  this.dgvPurchaseDetails.CellEndEdit += new System.Windows.Forms.DataGridViewCellEventHandler(this.dgvPurchaseDetails_CellEndEdit);

Hi,
        Please check what value you are trying to enter in the cell. I think it has got some restriction. Please share your code.
