function confirm_meth（）{ var confirm = confirm（'还有更多具有相同单号的项目。你要继续吗'）; if（确认== true）{ 返回true; } else { 返回false; } } ScriptManager.RegisterStartupScript（Page，GetType（），confirm_meth，confirm_meth（ ），true）; 提交按钮代码如下 string url = string.Empty; bool isAgri = true; int count = 0; //添加 foreach（grdRpt.Rows中的GridViewRow行） { CheckBox chk =（CheckBox）grdRpt.Rows [row.RowIndex ] .FindControl（chkselecdata）; if（chk.Checked == true） { count ++; int key = Convert.ToInt32（grdRpt.DataKeys [row.RowIndex] .Value）; if（row.Cells [4] .Text ==Agri Input） { isAgri = true; url = ConfigurationManager.AppSettings [SAPAgriInputPostingUrl]。ToString（）; } 休息; } }

function confirm_meth() { var confirmed = confirm('There are some more items with same slip number is there. Do you want to proceed'); if (confirmed == true) { return true; } else { return false; } } ScriptManager.RegisterStartupScript(Page, GetType(), "confirm_meth", "confirm_meth()", true); Submit button code as follows string url = string.Empty; bool isAgri = true; int count = 0; //added foreach (GridViewRow row in grdRpt.Rows) { CheckBox chk = (CheckBox)grdRpt.Rows[row.RowIndex].FindControl("chkselecdata"); if (chk.Checked == true) { count++; int key = Convert.ToInt32(grdRpt.DataKeys[row.RowIndex].Value); if (row.Cells[4].Text == "Agri Input") { isAgri = true; url = ConfigurationManager.AppSettings["SAPAgriInputPostingUrl"].ToString(); } break; } }

String strConnString = ConfigurationManager.ConnectionStrings["IvcSpiderDBConnectionStrings"].ConnectionString; SqlConnection con = new SqlConnection(strConnString); con.Open(); if (count > 0) { if (isAgri) { string slip_No = string.Empty; List<string> slipnoList = new List<string>(); List<dist_request> dist_requests = new List<dist_request>(); foreach (GridViewRow row in grdRpt.Rows) { CheckBox cb = (CheckBox)row.FindControl("chkselecdata"); if (cb.Checked == true) { int key = Convert.ToInt32(grdRpt.DataKeys[row.RowIndex].Value); slip_No = row.Cells[2].Text; Dist_Request dist_request = new Dist_Request(); LT_ITEMS lT_ITEM = new LT_ITEMS(); lT_ITEM.MATNR = row.Cells[15].Text == " " ? string.Empty : row.Cells[15].Text; dist_request = dist_requests.Where(r => r.SLIP_NO == slip_No).FirstOrDefault(); if (dist_request != null && dist_request.SLIP_NO != null) { dist_requests.Find(f => f.SLIP_NO == slip_No).PostingNav.Add(lT_ITEM); dist_requests.Find(f => f.SLIP_NO == slip_No).FLAG += "," + key.ToString(); } else { dist_request = new Dist_Request(); dist_request.SLIP_NO = slip_No; dist_request.BUDAT = DateTime.Now.ToString("yyyyMMdd"); dist_request.MBLNR = string.Empty; dist_request.FLAG = key.ToString(); List<lt_items> lT_ITEMs = new List<lt_items>(); List<returnnav> listreturnNav = new List<returnnav>(); lT_ITEMs.Add(lT_ITEM); dist_request.PostingNav = lT_ITEMs; dist_request.ReturnNav = listreturnNav; dist_requests.Add(dist_request); } } else { slip_No = row.Cells[2].Text; slipnoList.Add(slip_No); } } HttpHelper httpHelper = new HttpHelper(); if (dist_requests.Count > 1) { ScriptManager.RegisterStartupScript(this, GetType(), "showalert", "alert('More than one slip no selected no');", true); return; } else { if (slipnoList.Contains(dist_requests.FirstOrDefault().SLIP_NO)) { System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, typeof(System.Web.UI.Page), "Script", "confirm_meth();", true); } In the runmode when i click the submit i get alert message as "There are some more items with same slip number is there. Do you want to proceed?" Ok Cancel. i click ok in the below line i cannot get the System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, typeof(System.Web.UI.Page), "Script", "confirm_meth();", true); retrun value what is the mistake in my above code?
