DataSource Controls :: LINQ Suming Original Data Not Filtered View?
Jan 31, 2010
I can see the issue here but can't get my head around a dv and dv.Table unless I'm looking too deep into this.Essentially, I can't get AsEnumerable.Sum() on dv but on dv.Table but I need it on the filtered view (ie. dv).This is the framework the entire application is built on so I can't pass these parameters to the stored procedure! Well I could but cannot be bothered re-writing and testing eveyrthing!

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
var sql = from x in db.Managers
where x.M_Name == TextBox1.Text.ToString()
select x.M_Name;
in this code I'm selecting only the name that user entered in textBox
so i want to do like tis
String Name = sql.ToString();
means to store the value in string. so the problem is i can not assign the var to string.

I have zero experience with LINQ but had occasion to use it today. I implemented a working solution but do have a question.First, let me provide the background:I have 20 large web pages that altogether have several hundred data input controls on them. There are strong similarities between how each type of control is handled. Rather than wire up each control individually (ie. hard code it in the layout page)
foreach (View view in multiView.Controls)
foreach (Control ctrl in view.Controls)
switch (ctrl.GetType().Name)
case "DropDownList":
DropDownList ddList = (DropDownList)ctrl;

I'm trying to find an easy way to view the query that has been generated as part of the LINQ to DataSet syntax in my application. I found Scott Gu's blog and his creation of the Linq to SQL Debug Visualizer but it doesn't appear to work for my application. I am using OracleClient if that is important.
My next step is to simply configure the Oracle Manager for the database to see the query but I can't believe there's not an easy way to view this generated query.

I have a SQL data source control defined to filter data from a SQL database, sorted according to the date time in descending order. When i try and update a field of the latest record, the entire column, related to the field of the filtered search gets modified. I want to only update a field of the last record i.e. the last entry of the filtered data. How can i achieve it?

My page has ListView with SqlDataSource. I set SqlDataSource as DataSet and EnableCaching = True.
BEFORE I filter SqlDataSource, I don't have problem to get the record value for selected record data in my ListView.
AFTER I filter SqlDataSource, my ListView can display the filter record data properly, but I have problem to get the record value for selected record data in my ListView. The record value for selected record data does not refer to the record value what I am selecting.

I am working with GridView/TelerikGrid control. It is having filter option. When I filter the data,
I need to copy only filtered rows into Datatable for further processing.
Suppose I am having total 10,000 records. and when I filter on column say Dept="IT", I get 1000 records in grid. So these 1000 records only should get copied into Datatable. So How to achieve this ?
Cwhat can be done over this ? I tried number of properties for grid. But there is no property which will return fileterd data source. Also I am not able to go every page of Datagrid and collect the data. I can get data for first page only. If I need to collect the data by going to every page of gridview, what is the way for this ?

I am trying to export a gridview that is returned from a search form. The gridview also has paging enabled. When the searched records are found in gridview it is exporting all data.instead of exporting only the searched data.
How can I only export the records from the search results, but also the make sure the records on the different pages export also?

'm using a gridview with paging and sorting in asp.net (language = VB).The gridview shows all the artists in my database. I've added a searchbox above my gridview, so users can search for certain artists by name.The search option works. If I enter the name: John --> it shows the artists who have the name John.Now for the problem:If the user filtered the gridview (for eample searching for John) and switches to another page of the gridview, the gridview is again filled with all the artists instead of the artists that are named John.

Any advice will be appriciated.

My question is that, for each control the Stored Procedure called or not? If it is yes then it is time consuming and I need to use LINQ to DataSet or LINQ to Object rather than to call SP for each control. What is difference between LINQ to DataSet and LINQ to Object?

I am trying to select data with Linq and bind to a DDL. The custid field allows duplicates in this table, but I only want unique values in the ddl. I tried the following code:
[Code]....
The use of "Select Customer.CustID", with or without the Distinct, causes this runtime error. CustID is a valid field in the table, and it shows up in intellinsense and compiles. If I just Select Customer, the error goes away, but Distinct doesn't know to look for distinct custid's.
DataBinding: 'System.String' does not contain a property with the name 'CustID'.

I am new to MVC and this really probably should not be posted here but in a different forum topic. The reason I am posting here though is I am not sure if there is something about MVC that would prevent me from doing what I am looking to do.So here it goes.Maybe I am the only one out there that thinks this way but I don't care for and don't fully understand LINQ. I Like building my stored procedures passing my data to a datareader etc... and displaying what I need.
Now that being said I am wanting to learn how to make a true Data Repository and build from there but everything I find online especially here all gives me examples and instructions on how to do so using LINQ.Does anyone know of a site that will teach me how to do this without using LINQ or any form of ORM just allow me to write my stored procs how they need to be and build my classes for data access how they need to be.I may be wrong in this but it seems to me this would be the more light weight way of doing it.Anyhow as stated above the additional question to this would be is there any reason this would not work for MVC and actually any reason it is extremely (or at least for me) hard to find any documentation on this anywhere online?
