Need help selecting items using HierarchyID

Posted By:      Posted Date: September 14, 2010    Points: 0   Category :Sql Server
Hi, I'm using HierarchyID in my ProductCategories table. I then reference the CategoryID in the Products table to determine under what category the product is to be listed. The script for the ProductCategories table is at the end of this message. Here's what I want to do: I want to select products from specified category as well as its child categories. This is especially useful if the user ended up in a parent category that doesn't have any products of its own. This generally happens if the category is only being used as a parent container e.g. Electronics. So if the user ends up in Electronics category, I want to display products from child categories of electronics e.g. MP3 players, digital cameras, etc. Could someone help me with the SQL for this SELECT statement? Here's the script for ProductCategories table: SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO SET ANSI_PADDING ON GO CREATE TABLE [dbo].[ProductCategories]( [CategoryID] [int] IDENTITY(1,1) NOT NULL, [Category] [varchar](100) NOT NULL, [CategoryHierarchy] [hierarchyid] NOT NULL, [StatusID] [tinyint] NOT NULL, CONSTRAINT [PK_ProductCategories] PRIMARY KEY CLUSTERED ( [CategoryID] ASC )WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY] ) ON [PRIMARY] GO SET ANSI_PADDING OFF GO EXEC sys.sp_addextendedproperty @name=

Selecting Items in a databound ListBox

Hi All, I'm facing a problem while trying to programatically preselect few items in a databound ListBox. I have set the datasource of the listbox to a DataTable, with required Data and Value member columns. The selection mode of the listbox is MULTIEXTENDED. Platform: .NET  1.1 (not sure if the problem is relevant to other versions) I tried preselecting items in a different ListBox that is not bound to any datasource. I'm able to preselect items using the SetSelected method. Perfect!   How can I achieve the same for a databound ListBox? What am I missing? Any help will be very much appreciated.   Regards, Amirtha

Selecting items in ListView in C#




I have been struggling with implementing drag-and-drop for my listview. The thread about that is here. The result is that I am forced to take care of the clicks. I just did the logic to do Ctrl+Click, Shift+Click etc. However, I am having trouble with Ctrl+Up/Down and Shift+Up/Down.


The thing here is that when you hold down Shift it remembers one special item which I call the "base item". I need to know how to set this "base item". I set ListView.SelectedItem and gives the ListViewItem that was under the mouse focus. But this doesn't seem to be enough. :/


Any ideas?

jQuery: Styling DropDownList Alternating Items (Rows)

In the following example, I will show how you can style any asp:dropdownlist very easily.

The example demonstrates how you can change alternating row items background color, using the fadeTo() to add a nice touch in the dropdownlist. You can change alt rows with a couple lines.

Hide a repeater in ASP.NET C# if the DataSource contains no items?

I have an ASP.NET page that uses a repeater nested within another repeater to generate a listing of data. It's to the effect of the following:
In the (C#) code-behind I'm basically using LINQ to pull a listing of information from an XML document and bind that information to the first repeater.

Searching for the answer to this, it seems the method is to determine whether the data for the nested repeater is empty. If it is, then you set the visibility of the repeater to false.

Creating SharePoint items with CreateItemActivity

Instead of creating new list items from code in your workflow you can use CreateItemActivity. CreateItemActivity can be used for creating list items or files. Properties of interest for this activity are the following (most of them are self-explanatory):

Creating Sites/Lists/List Items under Current User Context in SharePoint By Using SPUserToken

Usually we do this by performing the action under RunWithElevatedPrivileges method and updating the listitem using SPListItem.SystemUpdate() method (see here). but this approach has its own flaws like (RunWithElevatedPrivileges will run under system account, we cannot use SystemUpdate for SPSite,SPWeb,SPList, since it runs under system we will "CreatedBy" by as SystemAccount).

HttpContext.Items and Server.Transfer/Execute

The problem was basically that when a Server.Transfer call was applied the script container (and also various ClientScriptProxy script embedding routines) would potentially fail to load up the specified scripts.

Get pixel format, raw format, property id list and property items image in VB.net - C#.net.

ListViewControl - how to group items by their value, for eg. date range



I have a table containing courses, columns are 

Name - "Yoga Classes"

DateStart - "2/23/2010"

DateEnd - "2/24/2010"

I am using ListView Control to bind it, is there a way to display them and group them by Month?

Thanks for help.

Adding new items to a Repeater control with transitions?



I am currently in the process of writing a facebook type 'activity feed' for a site. Currently I am binding the last 10 items to a repeater control, which contains a usercontrol representing each item. This works fine but there are a couple of requiremnts that are giving me problems and wondered if the the good people of the forum could make some suggestions.

The requirement is that when a user clicks a refresh button any new events are added to the top of the list, the previous items drop down and the equivalent number of old items drop off the bottom, all with nice slider transitions.

I have put the repeater inside of an update control and are able to handle the transitions by using RegisterStartup script to drop jquery calls onto the page for the slider. However I cannot find a way to dynamically add or remove new datarows to the repeater. I need the old items to stay in the repeater and be pushed down by the new items, so completely refreshing the datasource seems like a bad idea.

I was thinking about maybe storing the datasource in the viewstate and adding rows to that, maybe with an extra column on the end which stores what transition is needed on the databind for my jquery, but there will be a 'View more items' link at the bottom of the page, so I am worried that the list could get pretty large and there

LINQ to SQL - Validating if item is in Database, but if item is not items not inserting into databas



I am new to this, so bear with me.  I am writing an application in C# that uses LINQ to validate a datacontext off a textbox to see if the record exists already.  If the record does exist I inserted an if statement to advise the user that the record exists, if the record does not exist I would like to allow the record to be added to the database.  If I take out my else statement everything works fine as far as inserting goes, but I do not want to allow inserts in this scenario.  I have tried moving the if and else statement to different parts of the code but can't quite figure this one out.  Any help would be apprecaited, attached is the code.  This code is set to a button press.  As a matter of fact, if you see any other errors along the way please feel free to point them out. 



    protected void enterBTN_Click(object sender, EventArgs e)
        //make new data context

        SHCDataContext insNewAll = new SHCDataContext();
        //LINQ to check if customer exists in database
        var checkExisting = from c in insNewAll.Customers
                            where c.custLastName.Contains(custLastNameTB.Text.ToString())
                            select c.custLastName;
        //make list to store values

How to handle Active and inactive items in the dropdownlist?


It is a general ASP.NET questions. Many times some items in dropdownlist will become inactive (retired)or active again. It is easy to handle in the new records which use only currently active items.
