VS 2010 How To Load Child Data When Query A Parent

May 30, 2010

i have a one two many relationship on a form that loads empty so that the user have to do a search in order to populate the data into the form. To acomplish this, i created a filter (query) in the dataset. The filter works fine for the parent data, but how can i load its corresponding child data?

This is the code generated automatically when i created the filter in the DataSet:

VBCode

Try Me.TblConfidencialesTableAdapter.Buscar_Confidencial(Me.ConfidencialesDataSet.tblConfidenciales, TablillaConfidencialToolStripTextBox.Text)
Catch ex As System.Exception

.net - Parent/Child Relationships Failing When Getting Data From Parent Class With Multiple Forms Open?

Jun 24, 2009

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.

dim l = Mainform.subform.listofdata

Edit:I am using visual Studio 2008. Winforms, form designed using designer. In my mainform I am doing this

Protected Friend frmMain as Mainform
frmmain = new mainform

In frmMain I am doing this

Protected Friend frmsub as new Subform'
frmsub = new subform

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.

C# - Displaying Parent/child Data In A Gridview?

Oct 19, 2011

I'm trying to create a document that displays a list of items, with details below each item. I feel like what I'm trying to do should be relatively simple, and the answer is hiding under my nose, but I can't find what I'm looking for.

For an example, let's say I'm just listing people, with a child list of their favorite foods.

This is how the data will eventually be displayed:

[Code]...

I'm trying to do this with a gridview control. I'm not sure that's what I should be using. But what I'm having trouble with, is getting the gridview to only list items with a unique USERID. And then using that unique USERID to list each item individually below.

Is there any kind of "automated" way of pulling this off using standard .net controls without going in and manually piecing it all together from the codebehind?

VS 2010 Nested MDI Parent/Child Forms?

Mar 3, 2012

I have a MDI project that has a parent and several children forms. In some of the children forms I would like to make one of the forms to be a parent form with children. On this child form I wanted to make a tabbed MDI, which I can do, but I have found out that I can't make a child form a parent, from what I have found.

Is there any way to get around this? (As in nested MDI forms.)

VS 2010 Parent-Child Form Using DataGrids

Aug 5, 2011

I am trying to create a simple parent-child form in VB2010. I use a datagridview for each table/datasource and each is bound to the parent/child table and each table grid fills correctly. What I want is the parent-child relation to enforce filling the child table with only rows that fulfill the current row on the parent. I have created a DataRelation in the form load, but it will not permit a relation between tables in 2 different datasets. If I attempt to place both tables in a single dataset and define the PK-FK relation in the SQL Server I cannot create 2 separate datagrids from the same dataset.

VS 2010 : Change The Parent-child Relation In A Treeview Control At Runtime?

May 5, 2012

I want to program a water supply pipeline network in a treeview control. It has five node (junctions). The parent-child relation is based on a parameter (say pressure). Initially, the node 1 is parent and its child nodes are 2 and 3. The node 3 has child nodes 4 and 5. At run time the pressure changes. Now, node 3 is parent and its child nodes are 1, 4 and 5. The node 1 has child node 2.

Microsoft Report Viewer To Show Parent/child Data Such As Invoices Headers Followed By Invoice Details?

After several hours of searching the internet I could not find any Report Viewer tutorials that show a project that contains a parent/child report. I'm using rdlc report files.I can create a single report but we want to create a report that shows shows invoice header information followed by the invoice details followed by the next invoice header and details and so on.

If a sample project is not available, do you know of an online tutorial that shows how to do it?I saw something that might help on gotreportviewer.com about subreports, but it's in C# and not VB.Net so I could not figure out how it works.

Write Text From A Parent Form To The Active Mdi Child Form VB 2010

Jan 28, 2012

It has to be a simple line of code but I do not know how to construct it. Using VB 2010 Express, I have a MDI parent form and many child forms. I want the parent form to determine what child form is active and load data into the RichTextBox1 on the child form. Each Child form has a RichTextBox1. The parent form gets its data by loading a file.

I am close to a solution but just can't get there. You will see in the code below, if I make a direct reference to a specific child form, it works great. What I want to do is to use the Active Form function to determine which form to write to. I have looked at the MS tutorial which gets me close.
