MDI Form - Make A Parent Child Relationship
Sep 30, 2009I am working on my final project and I need to have 1 MDI Form. For the life of me I cannot figure out what to do. My book mentions doing this:
Dim childForm as New ChildFormClass()
childForm.MdiParent = parentForm
childForm.Show()
When I put that in the Parent form it doesn't like the ChildFormClass(). I wouldn't think it would be too hard to make a parent child relationship? I have tried looking for the MdiList property but I cannot seem to find it. I think I need to have some menu items to have a child form. If there is a way to have an MDI form without that I would like that. Does anyone know a good tutorial that explains creating MDI forms well, and what to do/put in the parent and child forms code?

View 1 RepliesSetting 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.
View 1 RepliesSql - 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.

Create The Relationship So That When Move Thruogh Master The Child Have Corresponding Records?
May 21, 2009I created a dataset.xsd and it contains two table adapters and these table adapters use stored procedure for select.in my vb form, i get value in text box and then fill table using tableadapter and pass parameter to sp. Till this point everything is working fine. Now these tables have relations and i want to create relationship and show the data from child table on basis of master table. How i can do it?
Example
Me.MasterTableAdapter.Fill(Me.dataset1.spMaster, 1) --1 is parameter which is passed to sp
Me. ChildTableAdapter.Fill(Me.dataset1.spChild,1) --same parameter is passed to child table.
Now i have the records in spMaster and spChild. how i create the relationship so that when i move thru Master the child have corresponding records?
Recursive Relationship, Master/detail-type Form, And Child Datagridview?
Apr 16, 2009I have a form that is set up like a master/detail form - fields on top with a child grid below. The difference here is that the child grid is reflective of a recursive relationship. That is the ID of the master has a one-to-many relationship with another attribute called "parent." the child grid displays all the children for that parent. It works properly except when a new record is being added to the master.My issue is that when the user clicks on the Add New button, the child grid then displays all the available parent records in the system instead of an empty grid. Once the new master (parent) record is saved, the grid reverts to proper behavior.Thus, my question: How do I prevent the child grid from displaying all the parent records when a new master (parent) record is being added?
View 1 RepliesFilter 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.

Nov 12, 2010Note: I am working with Visual Studio 2010 Professional. Note: There are a lot of MDI Child posts, but none (that I have found) that apply to my scenario... Scenario I have an MDI form with a UserControl docked at the top. The UserControl is for navigation and is ~50 pixels in height.

Databinding Through Child To Parent?
Feb 24, 2009I have two datatables inside a single dataset (all are typed). dtOriginalData contains roughly 25 or so fields, which included IDs, descriptions and other bits of data. The ID is the PKey in this case. dtEditData contains almost the same columns as the first,with a couple of extras thrown in. One of the fields in dtEditData is the ID from dtOriginalDatafter the two tables are loaded, I create a datarelation between the two using this ID field. I then update some of the fields in the dtEditData and set their expression to pull data from the Parent table (dtOriginalData) ... this is then fed to a grid. So far everythign works fineNow I need to add some functionality, displaying the Original Data, the Edited Data and the variances between the two.
The bindingContext is set cocrrectly. I've successfully bound all of the edited fields to their appropriate labels, and everything updates as I scroll through the data in the grid.It's all fine and dandy... except.... for the Original Data fields... I bound them to dtOriginalData.... and all I get is the first record displaying. It's not taking into consideration the relation between the two databases and advancing the index on it. So, what I need to find out, is if there is a way to do the databindings so that the two data tables will move in synch with each other, keeping the displayed values updated with the correct information. If, for some reason I can't find a way, I may have to resort to a gawd awful datatable with 30+ fields in it.

Child Record Won't Add But Parent Exists
Jul 13, 2011Working on an VB/ASP website in Visual Studio 2008. Getting the error "You cannot add or change a record because a related record is required in table 'abc'
It is true that table xyz (the target of the INSERT) is in a parent-child relationship with table abc. The PK in abc is a column RequestID_lng. The FK column in xyz is also named RequestID_lng
This is the only relationship these 2 tables are in.
I am trying to add a row in xyz with a value of 45 in the FK. There is already, previous to this action, a row in table abc with a value of 45 in the PK. So the parent already exists for this child.
I have used the watch window to copy my SQL code for the INSERT query that is being executed. I pasted that code into a new query in the Access DB and executed it without problem - it actually added the row that .Net should have.[code]...
