In the grid view is displayed with data retrieved from the database and at the footer there is a row of empty fields for the user to insert records into database and when user clicks on Add New, a new row of empty fields will be populated below.
The database.cs and stored procedure is used to stored the data into the database.

This is the stored procedure code:

I code this in business logic but its wrong as the error states the Insert method could not be found:

offset print
100
1000

water base
200
1000
C
ABC
offset print
950
1000
How to insert multiple records like above at once, and how to manage quantity user input is not over max quantity. In example above: Max quantity of Offset printing is 1000 (bind from database, visible=false)
Woker A does Offset printing with quantity 100, C does Offset printing also but with quantity 950, if we sum quantity A and C do will be over 1000 Ã message box: warning

I've been wracking my brains for a while. I have a master record that I want to add children to. In a database it's a one to many relationship with a foreign key in the child table.
I have a formview that I want to use to fill in all the master record info, and choose the child info from a dropdownlist, and click an add button, and have the add button add the child info to some control on a page. Then when the user clicks insert, the formview has an ItemInserting EventHandler that will handle all the logic for inserting the master, grabbing its primary Key.
So, I know what to do, I'm just not sure of what control to use, or what memory object etc., that I want to store the child info in until the master record gets created.
I'm sure this has been done a million times, but for all my searching, I couldn't find anything to help me. Does anybody have some advice or can anybody point me to an internet resource where this has been hashed out?

currently 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) .................

I have 2 tables in SqlServer 2008.
Table1: T1id, SomeData
Table2: T2id, T1id, SomeData
I am using DataAdapter.FillSchema to create shema of tables in DataSet. I created DataRelation on columns
T1id in both tables.
Now when i try to Update Sql Database T1id in Table2 remains 0 and not the value of T1id in Table1.
I can successfully update Sql Database if i fill DataSet with records first (Using DataAdapter.Fill), but that's not what i want to do. I don't need "old" records in my dataset. I want to use dataset just to store all imputs from user until the proccess is done and then insert all those records "at the same time".

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 have created a page with a gridview in asp.net that displays the records of a database table and allows users to delete checked records by clicking on a delete button. After I delete a record and I try to refresh the page from the browser (I am using mozilla)I get the follow message:
"To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier."
and if I click resend another record is deleted automatically. Even though I am reloading the gridview after the deletion the application executes again the onclick event of the delete button is executed and the gridview things that there is a checkedbox selected so the code executes my delete function again.
Is there any way to get rid of these behavior. I have been trying quit a few things but nothing works for me.

I have a database, one field is named "clicked" with values 0 or 1.
When the gridview is displayed I would like to show the value from the field "clicked" to be displayed as an image (example: instead of 0 to display and for 1 to display)
Is it possible?

Is there an easy way to search all the columns in the database?
I was the user to input a search word in a textbox and then search all of my database. I then want an array full of the primary keys of all of the records that had the search word contained somewhere in the record (i.e in any of the record fields).
This sounds really simple to me but I can't figure out how to do this and can't find examples online.
