DataSource Controls :: LinqDataSource.Insert(values) Versus InsertParameters
May 26, 2010
I use LinqDataSource and need to make insert not from any data-bound controls like formView (just by pressing button on page).
In SqlDataSource I can set InsertParameters like this
<InsertParameters>
<asp:ControlParameter ControlID="ddlPrice" DefaultValue="0" Name="Price"
PropertyName="SelectedValue" Type="Int16" />
<asp:ControlParameter ControlID="ddlDisc" DefaultValue="0" Name="Discount"
PropertyName="SelectedValue" Type="Int16" />
</InsertParameters>
and then just call Insert().
But in LinqDataSource we don't have method Insert() taking no papameters so I need to create collection with values I want to insert.

in the selected event it seems even though e.TotalRowCount really is the total row count, when I cast e.Result to a type in order to access the actual data only the current page of data is there? not all.
IEnumerable<InventoryGridItem> items = (IEnumerable<InventoryGridItem>)e.Result;
items only has the 15 records for the current gridView page, not all the records, is this normal? If I need to access all the items in the result do I need to stick with the selecting event instead?

I have the following code that seems like it should set my insertParameter but everytime an insert happens it uses the default parameter. Do i need to do anything special to make this work?
Codebehind:
protected void SetInsertParams(object sender, LinqDataSourceInsertEventArgs e)
{
if (lbl_Personnel.Visible)
{
lds_Personnel.InsertParameters["BudgetLineTypeCode"].DefaultValue = "S";
}
else if(lbl_Operating.Visible).........

I'm trying to execute a simple insert statement with the GUID and timestamp populated by default from the server. I have both of their default values set as (newid()) and (getutcdate()) respectively in SQL server. However, I receive the error when I try and execute the command "Insert Error: column name or number of supplied values does not match table definition". How do I construct my sql insert so my id and timestamp columns use their default values as assigned in sql server?

the table has the column date and worker. so i desire that the user writes the name of the worker and then enters a From and To range into two textboxes so that thorugh a loop function the name of the worker gets written into the table along with the range of chosen dates.

This is my code so far:
SQL = "insert into " & tableNameToday _
& "(ID, Name, Calories, Of_Which_Fat, Protein, Carbohydrate, Of_which_sugars," _
& "Fat, Of_Which_Saturated, Of_Which_Monounsaturates, Of_Which_Polyunsaturates," _
[Code]....
how do i multiply the columns like this. for now static explanation would be ok but eventually i would like to make it dynamic so there would be a text box for users to enter the amout they like e.g 160g then the table would know to multiply the columns by 1.6.

Is there a way to copy a row from one table and insert to another but at the same time insert extra values to destination table?Let's say source table Item has values:
ItemID
ItemType
ItemProducer
ItemModel
Destination table ItemHist:
ItemID
ChangeDate
ChangeReason
ChangedBy
ItemType
ItemProducer
ItemModel
I want to copy row from source table where itemid is 25, insert it into destination table and add extra values: ChangeDate, ChangeReason, ChangedBy. I tried:
INSERT INTO ItemHist (ItemID, ChangeDate, ChangeReason, ChangedBy, ItemType, ItemModel) VALUES (ItemHist.ChangeDate=GetDate(), ItemHist.ChangeReason="why not", ItemHist.ChangedBy="me")
SELECT ItemID, ItemType, ItemProducer, ItemModel FROM Item WHERE ItemId=25
but obviously it didn't work ("The name 'ChangeDate' is not permitted in this context. Only constants, expressions, or variables allowed here. Column names are not permitted.").

[Code]....
when I set category to 'Concerts' tyhe where clause is
'Category = Concerts'
this generates an error telling me there is no column called 'Concerts'. I assume I somehow have to enclose the search term in quotes, Ive tried single and double quotes, but nothing works.

I am trying to use the TableApapterManager.UpdateAll to insert values to master and child table. I had set the relation to cascade for update in the dataset and the HierarchicalUpdate to true. But stil when I run TableApapterManager.UpdateAll(dataset), I get a foriegn key violation error. Following is the code I used:
int ID;
DAL.Datasets.dsMembers.MembersRow rwMem = m_dsMembers.Members.NewMembersRow();
rwMem.u_name = mem.Name;
m_dsMembers.Members.AddMembersRow(rwMem);
DAL.Datasets.dsMembers.MemPhonesRow rwmemphn = null;
rwmemphn = m_dsMembers.MemPhones.NewMemPhonesRow();
rwmemphn.u_memberid = ID;
rwmemphn.u_phn = "test";
m_dsMembers.MemPhones.AddMemPhonesRow(rwmemphn);
m_adpMgr.UpdateAll(m_dsMembers);
return ID;
The error I get is "The INSERT statement conflicted with the FOREIGN KEY constraint "FK_MemPhones_Members". The conflict occurred in database "Family", table "dbo.Members", column 'i_memeberid'.
The statement has been terminated."

I use LinqDataSource and GridView.
I need an old value of field "PictureBig" in RowUpdating handler like this:
e.OldValues["PictureBig"]
To achieve this I use bound unvisible literal in edit item template...
<asp:Literal ID="ltBig" runat="server" Text='<%# Bind("PictureBig") %>' Visible="false" />
Is there any better ways of doing this?

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;

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?

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
[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.

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).

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.

I just started working with LinqDataSources and I was wondering how you retrieve values in a FormView DataBound Event.
With an ObjectDataSource I believe you can grab them like:

Is there a similar way to acheive this with a LinqDataSource?

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.
