Require Assistance Making A Menu From A Single Parent/Child Table?

Oct 25, 2010

I have a single table that holds my Categories

CatID, CatName, ParentID

I have often used this layout to show Root Categories where the ParentID IS NULL. I would like to be able to create a vertical Menu (using a repeater and an <UL><LI> that displays the Root Categories and ideally, a collapse panel that would expand with the subcategories. Given the above Table format, it is also easily possible to make the hierarchy unlimited.

how to make a single dataset that understands the Child relationship.

Filter Parent / Child Table In Linq Query Based On Entities In Child Table?

Jul 9, 2010

I have a table (Projects) which is linked to projectVersions on projectID..projectVersions contains several columns on which I'd like to filter a returned project (and associated projectVersions) list. For example there is a "capacity" column and a "country" column. I am doing a filtered list of projects on one page and I'd like to include all projects where any one of the associated projectVersions has a capacity of 750ml and a country of "France" for example.It may be that a particular parameter is not set and so I pass a zero to indicate not to filter on that.I guess this needs some kind of subquery as when I try and do something like this: [code] it doesn't work as the "xxx" bit, being one-to-many, expects me to specify an item to get at the entities within and yet I want to query where ANY of the associated versions match one of the criteria.

Refresh Table Adapter When I Have A Child Table Attached With Parent Table?

Dec 21, 2011

I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause.

Forms :: Same Menu Shortcuts In MDI Parent And Child

Apr 30, 2009

I want to use the same menu shortcut keys in a MDI child as in the parent...the problem is that the parent seems to receive the Event first and is calling his menu entry. The child (though it does have the focus) does never receive any event whatsoever...I can bypass this behaviour by adding a Textbox to the Menu, and the moment that one has the focus the menu shortcuts are working as expected (child gets it first, after that it's passed through to the parent).

Insert SQL 2008 Parent And Child Rows In A Single Transaction?

Nov 13, 2010

First, a little background (greatly simplified): I have two classes, one called Entity and one called Item which a subclass of Entity. They each store their individual properties in seperate SQL 2008 tables using TableAdapters generated by a strongly typed DataSet. The Entity class has a Save() method that looks like this:

Public Sub Save()
entityTableAdapter.Update(entityRow)
End Sub

[Code]....

Indeed, the SQL table does not contain a row in the Entity table with the necessary ID at this point because the transaction is not complete.

My goal is to prevent the Entity record from being inserted if inserting the Item record fails. I could write code to delete the Entity record again, but this does not seem very elegant to me...

C# - LINQ To SQL Join Two Tables To Select Parent Table Twice Based On Two Different Columns From Child Table?

Aug 23, 2010

I have two tables Employees and CafeLogs. Some employees can be cashiers and also customers at the Cafe shop.

Table structures:

Employees: EmployeeId(PK) , FirstName, LastName
CafeLogs: LogId (PK), CashierId, EmployeeId, Value, => CashierId and EmployeeId are the data from column EmployeeId of Empoyee table

Table relationship:

Employees 1:N CafeLogs (CashierId (FK))

[code]....

Right now I know how to select only LogId, Employee's name, and , Value, not with Cashier name yet.

Dim query = From log In db.CafeLogs _
Join emp In db.Employees On emp.EmployeeId Equals log.EmployeeId _
Select log.LogId, emp.FirsName, emp.LastName, log.Value

Forms :: Enable/Disable MDI Parent Menu From Child Form?

Jan 5, 2012

I'm writing an MDI app in vb.net vs2010. The MDI form has the default MDIMenustrip menu with several menu items. Each has some subitems. None of the child forms have a menustrip defined. I thought it would be easy to call a public subroutine in the MDI that would disable or enable the MDIMenustrip items. If I execute the routine from the MDI form, the menu items disable/enable just fine. THe problem I have is when I call the routine from a child form. How can I control the MDI menu from a child form?

VS 2008 Updating Child Table Before Parent?

Jan 11, 2011

I have a situation where a database table is updated with records inside a loop. Every record in this table has a parent child relationship with another table. This child table is also updated subsequently inside the same loop.I am creating the datatable for Parent table and adding records inside the loop, but committing the records in the database (using SqlCommandBuilder) outside the loop only once.

Inside the loop I am also calling the function for updating records in the child table. Because the adaptor and datable objects are created inside the child table function, I need to commit records in child table inside the function only. So this happens before commit of parent table. Because there is a PK-FK constraint in the database, an error is generated.

Simplest solution would be to bring all code inside one function. But I don't want to do that. Besides this parent child relations can go upto any levels.

Loop Through Child - Bind Textbox To Field Of Parent Table

Mar 22, 2010

First I have 2 tables, for example Customer and Orders, and in the database there is a foreign key relation between both. For clarity Orders have a foreign key field to the primary key of Customers, thus Customer is the parent and Orders is the child table of the relation. My application is a Windows Form application, and I add a dataset to the project, in which I drop the 2 tables, and the relations between the 2 tables is automatic added. Now I will om a form loop through the Orders table (witch is the Child table) and show in a textbox some fields of the Orders table and also the Name field of the related record of the customers table. Regarding binding a textbox fo a Orders field I do it this way,

Dim myDs As New DataSet1
Dim myAdpCustomer As New DataSet1TableAdapters.CustomerTableAdapter
Dim myAdpOrders As New DataSet1TableAdapters.OrdersTableAdapter
myAdpCustomer.Fill(myDs.Customers)
myAdpOrders.Fill(myDs.Orders)
Dim myBindingSource As New BindingSource
myBindingSource.DataSource = myDs.Orders
myBindingNavigator.BindingSource = myBindingSource
TextBox1.DataBindings.Add("Text", myBindingSource, myDs.Orders.OrderIDColumn.ColumnName)

But now I can't find how to bind a textbox to a field of the Customers table witch is the Parent table of the relation.

Jun 24, 2009

I have a main form, and some sub forms, and each sub form can have some sub forms.
