I am facing a situation wherein i have to ask the user for the files to upload and save them as blob in the database. I have a single file upload control on the page and user can add as many files as he wants. When the user browse the file and click add button then the file gets added at some temporary location on the page and later on when the user has specified all the files to upload then I would like to insert all these files using a single insert query in the database.

in my javascript popup i am getting the checked values but i need it in record by record in the lblsave data
Conseptually what I'm doing is simple, and technically it may even be simple, but I'm still rusty. Here's what I'm trying to do:
I have a webform that allows the user to enter a new record, and in there I have also included a couple FileUpload controls. Upon clicking the "Save" button, I'm saving the details entered into one table (ITEMS), and also inserting the FileUpload details (path, id, upload_user) into another table ATTACHMNTS). Because one ITEM can have many attachments, I needed to split the tables up. So on save, I need to save the ITEM, save the ATTACHMENT, and then also put the ITEM_ID in the ATTACHMENT table. I'm second guessing myself because I think all I'd have to do is after I do the ITEM insert, do a SELECT MAX on the ITEM table and hold the newest (MAX) id in a variable and then use it in the ATTACHMENTS update. I'm not 100% on this because there IS a chance that someone else could save a few milliseconds later and I'll link the wrong ITEM. See my delima?
I am facing a big problem with simple linq query.. I am using EF 4.0..
I am trying to take all the records from a table using a linq query:
var result = context.tablename.select(x=>x);
This results in less rows than the normal sql query which is select * from tablename;
This table has more than 5 tables as child objects (foreign key relations: one to one and one to many etc)..
This result variable after executing that linq statement returns records with all child object values without doing a include statement.. I don't know is it a default behavior of EF 4.0 . I tried this statement in linqpad also..but there is no use... But interesting thing is if I do a join on the same table with another one table is working same is sql inner join and count is same..but I don't know why is it acting differently with that table only.. Is it doing inner joins with all child tables before returning the all records of that parent table?

Currently users can select multiple records and hit the order button and everything has worked well. Now I have multiple pages in my gridview, and if a user selects a few records from the first page, and then goes to the second page, all the records (checked checkboxes) disappear from the first page.

In my DAL should I put a big query that join the 6 tables + the m:m reference tables (btw it produces multiple data that I don't need Please refer to my old question) and place all the data in it's specific object property or, should I use a single query for each table and create an object for each fetched table .. and finally send those to the UI ?If I wasn't clear enough please let me know what I further information do you need to know!

View 11 Repliescurrently I am doing an online store project using an example from one of your tutorials. In the grid view is populated with data and at the below of the grid view, there is a row of empty fields populated below. After user have enter all the necessary info and clicks on the Add New link, the data will be inserted into the database and it will also be displayed in the grid view itself. The software that I am using is called: MS VS 2008 C# The database that I am using is called: MS SQL Server 2008 This is the database.cs for inserting records into the database:
Code:
public bool Insert_ItemsRecords(string id, string itemName, string itemDesc)
{
SqlCommand cmd_ItemsList = new SqlCommand();
cmd_ItemsList.CommandText = "[VRM].[INSERT_ItemsRecords]";
cmd_ItemsList.CommandType = CommandType.StoredProcedure;
cmd_ItemsList.Parameters.Clear();
SqlParameter sqlParaID = new SqlParameter("@id", SqlDbType.VarChar, 10);
sqlParaID.Value = id;
cmd_ItemsList.Parameters.Add(sqlParaID);
SqlParameter sqlParaItemName = new SqlParameter("@itemName", SqlDbType.VarChar, 100);
sqlParaItemName.Value = itemName;
cmd_ItemsList.Parameters.Add(sqlParaItemName);
SqlParameter sqlParaItemDesc = new SqlParameter("@itemDesc", SqlDbType.VarChar, 1000);
sqlParaItemDesc.Value = itemDesc;
cmd_ItemsList.Parameters.Add(sqlParaItemDesc);
return executeNotQuery(cmd_ItemsList);
}
This is the stored procedure:
Code:
ALTER PROCEDURE [OS].[INSERT_ItemsRecords]
@id varchar(10),
@itemName varchar(100),
@itemDesc varchar(1000) .................
