I am developing the my asp.net project, I'm try to make ASP.net text box for Auto Generate code, but its not working correctly, sample Auto Generate code = ID1.
I'm try to use this part,
string txt = txtBatchNo.Text;
txtBatchNo.Text = "C" + Convert.ToInt32(txt.Substring(1, txt.Length - 1)) + 1;
Code:
protected void btnAdd_Click(object sender, EventArgs e)
{
int newId = 1;
if (selectGRNDetailId == -1)
{
{
try
{
if (dtFabricItem.Rows.Count > 0)
{
newId = Convert.ToInt32(dtFabricItem.Rows[dtFabricItem.Rows.Count - 1]["GRNDetailsID"].ToString()) + 1;
}
}
catch (Exception)
{
newId = 1;
}
}
}
else
{
newId = selectGRNDetailId;
}
if (dtFabricItem == null)
{
CreateFabricDetails();
dtFabricItem = dt;
}
else
{
CreateFabricDetails();
}
DataRow dr2 = null;
dr2 = dt.NewRow();

I am trying to insert around 5000 records in database using foreach loop. It is taking around 10 min which is not acceptable as per the requirement. I also thought about the approach in which first insert the records in a datatable and then converting it into XML pass it to stored procedure which do the insertion. But unfortunately it is not getting fit in my situation. Now i am doing the same thing using parallel.foreach but after inserting 10 records i am getting "Unique constraint violation for the primary key" error msg. As i am new to parallel programming so not getting the solution for it. Below is my code that i have done so for.

Getting error when generating the primary key value using the below function :

}
}
Where SR_NO is the primary key in that table.
Any help will be very much appreciated. Thanks in advance.
The fastest way to do such inserts is using ADO.NET, specifically, SQL Bulk Insert. If you're using SQL Server as your database, the relevant code will be something like this:
DataTable dt = GetDataTableFromExcel(excelFile, true);
using (var copy = new SqlBulkCopy(yourConnectionString) //There are other overloads too
{
BulkCopyTimeout = 10000,
DestinationTableName = dt.TableName,
})
{
foreach (DataColumn column in dt.Columns)
{
copy.ColumnMappings.Add(column.ColumnName, column.ColumnName);
}
copy.WriteToServer(dt);
}
Please look at my comment to other question
You could use guid as primary key into your table. It would help you to avoid problem with ##IDENTITY. At first you should generate new guid-identity, thank insert the generated value into a row
I am using Visual Studio 2015 and Entity Framework 6. I am trying to add entries from inputted information into multiple tables.
This is what I have so far:
protected void btnOrder_Click(object sender, EventArgs e)
{
using (FlowerCompanyEntities flower = new FlowerCompanyEntities())
{
int rFlowers = 0;
Boolean rVase = false;
DateTime DeliveryDate = DateTime.Parse(tbDelivery.Text);
string flowerArrangement = ddlListFlowers.SelectedValue;
if (flowerArrangement == "f2")
{
rFlowers = 1;
}
if (flowerArrangement == "f3")
{
rFlowers = 2;
}
if (flowerArrangement == "f1")
{
rFlowers = 3;
}
if (flowerArrangement == "f4")
{
rFlowers = 4;
}
if (flowerArrangement == "f5")
{
rFlowers = 5;
}
string vase = rbList.SelectedItem.Value.ToString();
if (vase == "NO")
{
rVase = false;
}
if (vase == "YES")
{
rVase = true;
}
Customers cust = new Customers();
Addresses Addr = new Addresses();
Phone Pho = new Phone();
Delivery Del = new Delivery();
Arrangements arr = new Arrangements();
OrderStatus ordstat = new OrderStatus();
Orders ord = new Orders();
Pho.Phone1 = tbPhone.Text;
Addr.Street = tbStreet.Text;
Addr.City = tbCity.Text;
Addr.States = tbState.Text;
Addr.Zip = tbZip.Text;
cust.FirstName = tbFirstName.Text;
cust.LastName = tbLastName.Text;
Del.DeliverDate = DeliveryDate;
arr.FlowerID = rFlowers;
ordstat.OrderStatus1 = tbStatus.Text;
ord.Vase = rVase;
ord.OrderMessage = tbOrderMessage.Text;
try {
flower.Phone.Add(Pho);
flower.Addresses.Add(Addr);
flower.Customers.Add(cust);
flower.Delivery.Add(Del);
flower.Arrangements.Add(arr);
flower.OrderStatus.Add(ordstat);
flower.Orders.Add(ord);
flower.SaveChanges();
Response.Redirect("Orders.aspx");
}
catch { }
}
However, on the button click i get an exception error. I also just realized that some of those tables -- with those entries would need the foreign key of the other tables put in.
Question: How do I add all these entries to my database when there is multiple tables and foreign keys?
I am trying to make paging item counter something like __ of _ items like 1-6 pf 21 item and 6-12 of 21. can someone show me how to do it ??

lbl_totalResult.Text = ds.Tables[0].Rows.Count.ToString() + " " + "Resources Found";

rp_resList.DataBind();
}
}
Try this:
private void BindResourcesRepater()
{
// your existing code...
int numberOfItems = ds.Tables[0].Rows.Count;
lblCurrentVisibleItems.Text = GetCurrentVisibleItemsText(numberOfItems, objPds.PageSize, objPds.CurrentPageIndex);
}

int startVisibleItems = currentPageIndex * pageSize + 1;
int endVisibleItems = Math.Min((currentPageIndex + 1) * pageSize, numberOfItems);
return string.Format("Displaying {0}-{1} of {2} items", startVisibleItems, endVisibleItems, numberOfItems);
}
I'm not sure what label you want to display this in, but in my example I've used one called lblCurrentVisibleItems. Replace this with whatever label you want to use.
I need to modify a dataset before binding it to a gridview.
When I walk through the complete code block, and hover over dsEmployeeOrg, that records
dont appear modified. What am I missing here?
My code is:
DataSet dsEmployeeOrg = eCorporateStaffMgr.GetEmployeeAccessLevel(oEmp);
DataTable dt = dsEmployeeOrg[0];
string sManagerID = "";
string sSupervisorID = "";
string sEmployeeID = "";
for (int i = 0; i < dsEmployeeOrg.Tables[0].Rows.Count; i++)
{
sManagerID = dt.Rows[i].ItemArray[3].ToString().Trim();
sSupervisorID = dt.Rows[i].ItemArray[4].ToString().Trim();
sEmployeeID = dt.Rows[i].ItemArray[5].ToString().Trim();
if ((sManagerID.ToString().Trim() != sSupervisorID.ToString().Trim()) && (sManagerID.ToString().Trim() != sEmployeeID.ToString().Trim()))
{
if (sSupervisorID.ToString().Trim() == sEmployeeID.ToString().Trim())
{
// This is a Supervisor record
dt.Rows[i].ItemArray[2] = "1111";
}
else if (sSupervisorID.ToString().Trim() != sEmployeeID.ToString().Trim())
{
//This is a Employee record
dt.Rows[i].ItemArray[2] = "0000";
}
}
}
Please modify your code as below
DataSet dsEmployeeOrg = eCorporateStaffMgr.GetEmployeeAccessLevel(oEmp);
DataTable dt = dsEmployeeOrg[0];
string sManagerID = "";
string sSupervisorID = "";
string sEmployeeID = "";
for (int i = 0; i < dsEmployeeOrg.Tables[0].Rows.Count; i++)
{
sManagerID = dt.Rows[i].ItemArray[3].ToString().Trim();
sSupervisorID = dt.Rows[i].ItemArray[4].ToString().Trim();
sEmployeeID = dt.Rows[i].ItemArray[5].ToString().Trim();
if ((sManagerID.ToString().Trim() != sSupervisorID.ToString().Trim()) && (sManagerID.ToString().Trim() != sEmployeeID.ToString().Trim()))
{
if (sSupervisorID.ToString().Trim() == sEmployeeID.ToString().Trim())
{
// This is a Supervisor record
dt.Rows[i][2] = "1111";
}
else if (sSupervisorID.ToString().Trim() != sEmployeeID.ToString().Trim())
{
//This is a Employee record
dt.Rows[i][2] = "0000";
}
}

You are using so much code. Its would be better if you follow the MVM architecture and try to set Bind the textblocks to your viewModel. Lets consider the following scenario.
You have binded the xaml elements to selectedItem in your viewModel. Now when selectedItem's value is changed Notify event is triggered which will notify the UI and the values will automatically be updated.
I recommend you to study viewmodel and try to implement it. Its really easy and would save you a lot of hassle.
Try implementing some samples
Hope it helps :)
I got this ...
Actually if we want to update that we need to change text of each text box . So after the selection change , Try it like this.
public void createListPicker()
{
lp = new ListPicker();
lp.BorderBrush = new SolidColorBrush(Colors.White);
lp.BorderThickness = new Thickness(3);
