DataSource Controls :: LINQ Query To Grab The Last 5 Rows From A Group?

Jan 8, 2010

i have the following objects:

Event:

- EventID (PK)
- GroupID (FK)
- StartDate

Group:

- GroupID (PK)
- GroupName

What i need to do is select the last 5 events for each group using LINQ to Objects. I tried starting with:

[Code]....

But i'm not sure how i only take the last 5 per group.

The simple way of doing this is to get the groups and then have a property on that which returns the last 5 events but if i databind this i will have to use a nested Repeater/ListView. Ideally i would like to have a row foreach event.

DataSource Controls :: Count The Number Of Rows Returned From The Database?

Jan 17, 2010

I have executed my query in VB with:

[Code]....

I now want to count the number of returned rows so that I can say:IF rows_returned = 1 then login else deny
I think you get the idea.P.S. I know this is not the most secure method of login but I do not want to use the ASP.NET configuration manager as I like to understand what is happening. I am starting off very simple and I shall work up from there.

Forms Data Controls :: Gridview Row Count / How To Get A Count Of The Number Of Rows That Are Returned

Dec 17, 2010

When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?

Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.

LINQ Query - Collapse Two Rows Into One

Nov 26, 2013

Using a LINQ query and an aspx page with an Infragistics webdatagrid control, I am generating data that look like this:The data come from my dataset: There is another column which is TobaccoUse and it is N, Y, N, Y, N, Y, etc for each row. There is also a column for the rate, and it is 147.32 for all rows (test data). But it could and most likely will, especially as the ages increase, be different, like $250 for a 25-year-old smoker but $200 for a 25-year-old non-smoker.

The grid I want to present needs to collapse every two rows into one, so you see one row for 0-17 smoker and non-smoker, etc. I do not know how to write this query. I don't actually know how to write any LINQ query but I've enhanced some existing ones, or understood them, but it's easier to read something that exists than write it new or change it dramatically, which I believe I need to do.

The query right now is:

Code:
var medRateBook = from rates in dsMedRateBookRates.Tables[0].Rows.Cast<DataRow>()
select new
{
DivisionNum = div.DivisionNbr.Trim(),
Age = rates["agedesc"].ToString().Trim(),
TobaccoRate = rates["calcratePreferred"].ToString().Trim(),

DataSource Controls :: How To Select Rows From A DataTable And Create A New ViewList With The Selected Rows Only, While ...

May 31, 2010

I have one big DataTable with X rows. I want to select Y rows from it and bind them to a new ViewList. While doing it, I want to delete these rows from the DataTable (Having X - Y rows).

What is the best and fast way to do it?

I don't know if it is better to create a new DataTable to have the Y and after that bind them to a ViewList or something else?

I'm also looking for example in code how to select/delete rows from DataTable.

DataSource Controls :: Return Unique Rows : T-SQL Query

Jun 11, 2010

I have an SQL database table like the following:

ID // Code // Shape

The ID is the integer identifier.

On one line the Code may be OX01 and shape Hexagon for example

Then the next line the code is still OX01 but the shape is Triangle.

What I want to do is be able to pull back data for every line that is equal to a unique Code column. in the above example OX01 Hexagon would be returned but not OX01 Triangle.

I've tried using SELECT DISTINCT but it brings back all records and doesn't filter them correctly.

I've considered having another column which could have Child/Parent data so that only the parent is returned but i'm sure there must be a better way of doing this.

DataSource Controls :: SQL Query Return Incorrect Number Of Rows?

Mar 29, 2010

I am working on a small project. I ran the query below to get the maximum userid and increase it by 1 to create a new userid. However, when I run the query, it does not display the values that I enter into the database using insert statement. For example, if I open the table called login, I can see there are three records. If Irun the select statement, it only return one record which is the one that I enter manually when I first created the table. If I run the same select statement and give it a user id that I created, it returns the correct result.

Data Controls :: Get Total Count Of Rows In GridView When AllowPaging True

May 7, 2015

I am using a grid view and a textbox(out of gridview to display the total rows in gridview) , i am doing Paging in GridView , and pageSize is set to 5 ; so far i did this

protected void ExistingMappedGrid_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
totalRowsLabel.Text = "Total " + ExistingMappedGrid.Rows.Count + " records.";
}
it shows the number of records , but not total ! it shows only the records displaying on the page .

e.g.

if i have a total of 8 records , not page index works and shows 5 rows in gridview and other 3 rows on 2nd page index , but if on first instane page shows 5 records in gridview then textbox shows 5 and when i click on second page index it shows 3 rows  ( THAT"S NOT WHAT I CODED AND NOT NEEDED ) i want total rows to be shown
