code SQL to retrieve records from multiple random selection list box


Having problems coding a query.

Got a list box that allows for multiple selections (holding down the control key) the selection quantity is basically unlimited, but should never be more than 50 to 100 items from the listing of about 3000 items.

How can I code the SQL statement to select the choosen record data? I think I have the selection list worked out by populating an array but I am not clear on how to build the SQL query.

Any help would be appreciated.


Thanks again

Playing with Linq grouping: GroupByMany?

One of its features is grouping. Many people understand grouping like it is defined in Sql. Linq is implementing grouping quite the same way. Let's discover this syntax and how to make consecutive groups easier.

LINQ : Implementing IN and NOT IN

Linq: how to share parameters between lambda expressions ?

When using Linq to objects, you will quickly feel the need to pass some parameters from a method to another but it's not so easy because each Linq method is not calling the following one. In a Linq sequence, each method is using the result computed by the previous one. So, local contexts are not visible from one method to another.
The compiler is using two technical different ways to let parameters go out of a method.

Linq to Sql CompiledQuery container

Ok now let's go. Here is just a little trick but with some interesting patterns that could be useful in some other contexts not connected to Linq to Sql.

When using Linq expressions, like with Linq to Sql, translating the expression into something else (sql for example) is taking time and resources. Sometimes it's negligible, sometimes not...

LINQ to SQL Paging using GridView in C# and ASP.NET 3.5

This tutorial will show you how we can extend the LINQ to SQL Class and create methods that will allow us to page data from a SQL database. C# version.

What is Lambda Expressions In LINQ

A lambda expression is an anonymous function that can contain expressions and statements, and can be used to create delegates or expression tree types.

All lambda expressions use the lambda operator =>, which is read as "goes to". The left side of the lambda operator specifies the input parameters (if any) and the right side holds the expression or statement block. The lambda expression x => x * x is read "x goes to x times x." This expression can be assigned to a delegate type as follows:

ASP.NET Multiple Selection DropDownList with AJAX HoverMenuExtender

Recently, I was looking for a multiple selection dropdownlist control for my new project. After spending some time researching for it, I decided to put together all my finding in one web user control. This web user control consists of an ASP.NET AJAX HoverMenuExtender, JavaScript, StyleSheet and CheckBoxListExCtrl . The final product will work with or without a MasterPage and you can drag and drop more than one instances of the control on to the page.

LINQ to SQL Performance Considerations

As developers we have a wide array of tools at our disposal. One of the most time consuming, but most beneficial tasks we must undertake is to determine which of those tools to use for a given situation.

Generate Random Numbers

SQL Server has a built-in function that generates a random number, the RAND() mathematical function. The RAND math function returns a random float value from 0 through 1.

Passing Linq Statement between master and content page


I usually work with windows forms, and am just starting to work with ASP.Net, so appologies if this is a dumb question!

I have a master page which has a search button on it. The results of this are built up using a Linq statement and if there are any results, I want to display the results in a contents page.

On the masterpage, I have the following code:

Private _res

    Public Overridable ReadOnly Property SearchRes()
            Return _res
        End Get
    End Property

 Private Sub DoSearch()
   'some code to get a linq result

    If res.Any Then
            _res = res
            Server.Transfer("SearchResults.aspx", True)
            'no results
            LabelNoRes.Visible = True
        End If
 End Sub

On the SearchResults.aspx page I have this code.

Dim m As pxSite = CType(Page.Master, MasterPage)
        If m.SearchRes IsNot Nothing Then
            Label1.Text = "Results found = " & m.SearchRes.Count
        End If

m.searchRes is always nothing. 

What am I doing wrong here?


Gridview Enable Selection Problem



I have a gridview with Enable selection and Enable Paging equals to TRUE.

I also set the PageSize of my gridview to 4 so that I only displays 4 rows per page.

The problem is when I click the pager in the bottom of my gridview, my gridview is disappearing and no records appear.

Here is code behind of my gridview:

If e.Row.RowType = DataControlRowType.DataRow Then
                e.Row.Attributes("style") = "cursor:pointer"

                e.Row.Cells(2).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(3).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(4).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(5).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
                e.Row.Cells(6).Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
