Insert SQL 2008 Parent And Child Rows In A Single Transaction?
Nov 13, 2010First, 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...
Add Rows Inbetween Rows In Gridview Based On Parent And Child Node
Jan 19, 2011I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes. If i expand the First Parent Node Called "31" then according to the Number of Child Nodes (for first parent node(31) there are 5 child nodes.) add rows in the gridview.
These New rows should be add under the 31-xxxx. If i expand the 32 Parent Node based on number of Child Nodes, add rows under the 32-xxxx. [Code] I am getting the rows in the end of the Gridrow not in the Specific row.
Sql - Inserting Multiple Parent Rows And Multiple Child Rows For Each Parent With ADO.NET In One Setting
Nov 28, 2011I am looking for a howto or someone expert in ADO.NET who can explain me how to properly solve the following scenario:I have two datatables in a dataset:
ParentTable (ParentID, Name) for user data ChildTable (ParentID, ActivityID, ...) for schedule data
Tables are linked together at the database level by ParentID which is an Identity column in ParentTable.
Both tables are data bound to a separate DataGridView on the GUI. There supposed to be a "1 parent/N children" relationship between the tables, meaning if I create a new entry in the ParentTable (a new user) I get a clean DataGrid in the child grid to type schedule data for the user. So I setup two DataAdapters for each table to fill their result into a DataSet. I also set up a DataRelation object and assign it to the DataSet to link the two tables by their ParentID columns. Also when I add a row into the ChildTable via DataGrid I use SetParentRow to set the parent row.

VS 2008 - Adding Rows To Databound DataGridView From Child Form?

I have two forms, one contains a datagridview that is bound to a table using 'datagridviewbindingsource' and contains an 'add' button.

Setting A Value In Parent Row For A Column That Is Grouped Sets Child Rows To Nothing
Apr 13, 2012i have a Janus grid, which has two columns and the rows are organized in a hierarchical order i.e. parent and child rows. One of the columns in the grid is grouped (by dragging the column in the group by box above the grid). I have a cell-changed event that is fired when a cell content is changed. I do this in the cell-changed event:[code]If i change the value, in a parent row, of the grouped column then the child rows are set to Nothing. After the last line in the above snippet, child rows of row are set to Nothing. On the other hand, this problem does not occur if i change the value of the other column (which is not in the group by box). The problem occurs only if i group a column and change its value not otherwise.

VS 2008 Update Parent & Child With Relation
Aug 7, 2011I am going to ask a dumb question. I want to update my tables (two). There is a one to many relation between them. I know how to update when only one table is update, but how do i update when there is many on the other side. My problem is that , if one of the records on the many should become redundant, how would i delete it in the update process. If only the content changes , it is not a problem, i know the data just gets written back to the tables, but if one of the child records is not delete, how would it work I need some clue on the SQL statement using OLEDB
View 2 RepliesVS 2008 Updating Child Table Before Parent?
Jan 11, 2011I 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.

View 2 RepliesVS 2008 : Adding Parent And Child Nodes To TreeView?
Oct 31, 2010I am not sure I am getting the concept of referencing nodes in a treeview. When I hard-code nodes like:
tnParentNode = New TreeNode("ABC")
tvReports.Nodes.Add(tnParentNode)
tnParentNode = New TreeNode("Some Other Company")
[code]....
I get two parent nodes and one child off Some Other Company. However, when I pull information from a couple of tables to set up the parent and then the child nodes, I only get the parent nodes.So I pull the main parent nodes from one table and the child nodes from another table.This code pulls the parent nodes without any problem:
strSQLText = "SELECT lID, sCatName FROM Category ORDER BY iSortOrder DESC"
reader = GetReader(strSQLText)
While reader.Read
[code]....
But this does not add the child nodes. I am assuming it is because of the first line in the above reader.read while loop. I must not be referencing the proper parent node but I am not sure how to do it.

Filter Parent / Child Table In Linq Query Based On Entities In Child Table?
Jul 9, 2010I 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.
