DataSource Controls :: Accessing SQLDataSource Results For If Statement?

Feb 4, 2011

I have a single column returning SQL data source and I want to use the data for a simple if statement, but for the live of me I can't figure out how to do it. *oh for the old days, I wrote the same thing in simple asp in about 45 seconds*


For the life of me I can't figure out how to get that data into a variable or any way to access it. I know its probably simple. I have tried functions, etc off the net but everything I try results in another error.

DataSource Controls :: LINQDataSource Multiple WhereParameter?

Mar 23, 2011

I am trying to program the where prameters for this in code behind in C#, and is there really no way to do more than one parameter? Or am I not understanding this correctly? It seems only the 2nd parameter gets executed, no matter which one is at begining. I debug and seems they both get executed fine, but my listview doesn't get filtered and instead only the 2nd paramter works. Look at my code:

Also, if I do myLinq.Where = "division ==1 and someotherInt = 2", it works fine, but if I do two different data types, it will throw error. Since I want to filter with two different data types, hwo do I do this?

Parameter pram1 = new Parameter();
pram1.Name = "division";
pram1.DbType = DbType.Int32;

DataSource Controls :: Multiple Inserts With LinqDataSource?

Sep 4, 2010

I'm having a question about the LinqDataSource. Does anyone know if it's possible to perform multiple inserts with the LinqDataSource? Let's say for example that I have 2 tables.

Table A
AID = PK autoincrement Name AddressA FK AddressB FK
Table B
BID = PK autoincrementStreetNumberPostalCodeCountry

These tables are just examples to clarify my question. Let's say that I have a FormView with a LinqDataSource where the user can enter his name en a billing address (A) en delivery address (B). Now I would like to know if the LinqDataSource is able to insert 2 records in table B and use these ID's to insert them in table A together with the name?

DataSource Controls :: How To LinqDataSource Date Parameters

Jun 15, 2010

I need to retrieve data using a date as an input parameter. I created a WhereParameter and passed in a date value that I know to exist in the database, but no data is returned. Heres my code


Ive passed in '02/06/2010' as the date, in the database, the Startdate column has several values of '2010-06-02 13:08:50.503' so I guess its not being found because of the time part. Whats the best way to make sure that I retrieve the correct data ? Im not concerned about the time at all, I just need all rows for 02/06/2010.

DataSource Controls :: Get Data From A LinqDataSource From Code Behind?

Nov 18, 2010

If I have a Linqdatasource that isn't connected to a a bound control on my page how do I use the data source to read data in the code behind. ie

var query = (from x in linqdatasource select x)

What I actually want to do is create a data array (myArray) within the code, read all of the data from the linqdatasource (selecting 1 field to form tableDataArray), then compare the two arrays and then write (insert) those into in myArray that are not already in the datasource to the datasource (ie execute an insert back on the datasource).

DataSource Controls :: LinqDataSource.Select Syntax?

Jan 14, 2010

Where can I find documentation on the syntax that is expected for LinqDataSource.Select? It seems to be different from what I would do with Linq inline in C# code. For example, concatenateing something in Linq I would normally just do this in the projection:

new { FullName = (person.FirstName + " " + person.LastName ) }
However, with a LinqDataSource the only way I've found to do this is like this:
new ( String.Concat(person.FirstName, " ", person.LastName) as FullName)

I literally spent hours trying to figure this out, and only succeeded when I found a blog where someone gave this verbatim as an example. So I still don't understand why the syntax is different, the braces versus parens, aliasing, Concat operators. Next time I do this I want a better understanding so I am not playing this guessing game. It's like being handed a compiler, and trying to write a program when you don't know what language the compiler compiles.1. Are there different "flavors" of Linq? Like a VB Linq, and C# Linq?2. If so, is the LinqDataSource using a VB flavor of Linq?3. Really, what is really important to me, where can I find documentation on this particular falvor of Linq that the LinqDataSource expects? The documentation for the LinqDataSource itself gives nothing more than extremely simplistic examples.

DataSource Controls :: Programmatically Add An Updateable Formview With Linqdatasource?

Aug 7, 2010

I have a gridview on a page and based on the row selected I need to fill out a form view (dynamic data enabled) from a linqdatasource. On gridview_sleectedindexchanged I create the linqdatasource and set it as the datasource for the formview. It displays nicely but clicking update returns a "Could not determine a MetaTable" error for the datasource mapped.

THe goal is to create a single page that allows users to select a row then get the appropriate data, create an updateable formview so further edits can be done. Do not want to scaffold.
