Assigning a var with a value from a database grid
currentID = Convert.ToInt32(GridView_ABC.DataKeys[0].Value);
I get the error 'Input string was not in correct format' currentID is an integer var. When I hover over the GridView_ABC.DataKeys[0].Value it is """, it should be an integer.

I have several web forms which use a GridView linked to a DataSource control which is defined at design time as follows:
<cc1:pgsqldatasource
id="dsStates"
runat="server"
connectionstring="<%$ ConnectionStrings:PgSqlConnection %>"
oldvaluesparameterformatstring="Original_{0}"
providername="<%$ ConnectionStrings:PgSqlConnection.ProviderName %>" >
</cc1:pgsqldatasource>
As you can see, the connectionstring parameter is defined to a specific connection string name and I need to be able to set such a parameter to a different value, for example, to a session variable content.

I am storing a custom "Organisation" object as a session variable. One of the properties of the Organisation object is "OrganisationID" (integer). I have a DataSource that requires a parameter value to run, and I want to use a SessionParameter to populate this. In a previous version, I stored the OrganisationID directly as a session variable. In that case, I could easily access it like this:
[Code]....
However, how do I now access the OrganisationID property of an "Organisation" type session variable (called "Organisation")? I have tried this, which does not seem to work: <asp:SessionParameter Name="OrganisationID" SessionField="Organisation.OrganisationID" Type="Int32" />

I have an objectDataSource which uses my stored procedure GetNotifications
And my GridView is bound to that objectDataSource
the only problem is that my stored procedure requires the variable @UserName and then returns the values for that username, but I do not know how to pass the variable to the objectDataSource, does anyone know the code for this?
I can get userName from HttpContext.Current.User.Identity.Name but how do I pass that to the objectDataSource?

I am using a data list to display some value retrieved from a SQL query. My problem is that I would like to insert a variable for the field of ISDS_454.dbo.booksusers.userID. The variable has already been declared and stored upon page load. I just need some way to get it within the SQL query for the datalist.
<script runat="server"> Sub Page_Load()
Dim ID As String = "D07AD7E0-8E34-4C18-9B4D-10576B0CC6BF" End Sub
</script> <asp:DataList ID="DataList1" runat="server" DataSourceID="SqlDataSource1">
<ItemTemplate> fic: <asp:Label ID="ficLabel" runat="server" Text='<%# Eval("fic") %>' />
<br /> <br /> </ItemTemplate> </asp:DataList> <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ISDS_454ConnectionString %>" SelectCommand="Select COUNT(*) as fic
From ISDS_454.dbo.Books, ISDS_454.dbo.booksusers, ISDS_454.dbo.Genre
where ISDS_454.dbo.Books.ISBN = ISDS_454.dbo.booksusers.ISBN
And ISDS_454.dbo.Genre.Genre_ID = '1'
And ISDS_454.dbo.booksusers.userID = 'D07AD7E0-8E34-4C18-9B4D-10576B0CC6BF'">

I've done some SSIS package work in the past, but am by no means an expert.
I want to use an SSIS package to do the following:
1. Get the file name of the newest file in a windows folder (using a filename template like his: filename_ *.txt where the * part is always a date in the format of yyyy-mm-dd.
2. Use that file name in later portions of the SSIS package by reading the file and transferring data from it to a SQL table using a Data Flow task.
and use the result (which should be the name of the newest file) to open that file and pull data out of it and into a 2nd SQL table. I admit, I'm not sure how to use the dynamic result of this SELECT query as the file name in a flat file connection manager.

I'm making a page with a DropDownList (called ddlSupp) that contains several suppliers, and I populate it with an SqlDataSource, all in front code.
In another part of the page I make a CheckBoxList, and populate it again with an SqlDataSource. The select command of the SqlDataSource is a procedure call to my MySQL database. However, what the CheckBoxList gets populated with depends on who is selected in ddlSupp. How do I make a variable in front code that will take the value from ddlSupp and populate my checkbox accordingly?
Here is my code:
[Code]....
I get a MySQL error at (<%$ddlSupp.SelectedValue %>) so I know the wrong value is being passed into the query. How can I fix this?

I need to use a global variable as a parameter for the SqlDataSource element. I capture the user Name when he/she logs in:
Public UserName As String
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
UserName = Page.User.Identity.Name
End Sub
Then, I need to use the UserName to search the SQL DB and show only logged user personal information.
SelectCommand="SELECT * FROM [Member] where [UserID]= UserName"
What is the sintaxe to use a global variable into the SQL Select Command?

I am modifying a rather large ETL package using BIDS. It builds a datawarehouse, so there are many sources and a single destination. There are quite a few data flow tasks, and their connection strings are read into variables from an encrypted source. All the data flow tasks are arranged serially because of variable locking issues - occasionally two DFTs attempt to simultaneously lock the variable and it fails. I realize there are script solutions out there, but I am looking for perhaps a more elegant (easier) solution than to apply scripted solutions to tons of packages over something so trivial.
I came across the "RetainSameConnection" connection property, and I have a hunch this could be the solution. My reasoning is: If there's only one connection to a data source, there should only be one read operation from the variable. At least, it makes sense when SOURCING.As for destinations, I'm not sure if it's a good idea to have data from multiple sources flowing in through a single connection.This is my first week working in ETL so I don't know all the nuances of databases, ETLs, connections, etc.

I'm working with Front Page 2003 & ASP v. 1.5 For an online auction, I have created a table with 3 columns: username, amount, highbid ORDERED by Amount DESC.
I want to look at the 2nd record in the table, create a variable from the "amount" field, add 1,000 to it and post it in the first record's "highbid" field.
Then display on my web page the first record "username" and "highbid"
I have been stumbling around with trying to create a custom query in the database results wizard of FP 2003.

I wrote a linq code to read from database if its value is equal to textBox that user enters.
I dont wanna show the result in Gridview,so jz I wanna use that value. The code I wrote is
