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.

Basically I have two forms - Form1 has a DataGrid on it (Infragistics) and in the double-click row event it creates an instance of the EditForm and passes along the UniqueId for editing. Once the user saves the changes (if they make changes) - I want the DataGrid on Form1 to refresh. Here is how I thought I could get this to work ... I create a public property called RefreshRequired as boolean. Before unloading the EditForm it sets this property to true. Then Unloads. This continues the code in Form1 (which showed the EditForm as modal) but RefreshRequired is still showing as False? Why isn't my EditForm able to set the property?
FORM 1

In VB6, if you put a picturebox on a form and then put a control inside the picturebox, then the control would be a child of the picturebox. Its location would be relative to the picturebox and not the form.If you do the same thing in VB 2005 Express , the control seems to still be a child of the form and not the picturebox (i.e. its location property is relative to the form).Is there any way to make a control or graphic inside a picturebox a child of the picturebox and not the form?

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

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.

Note: 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. When I show a child form with its WindowState property already set to 'Maximized', the child form shows maximized in the MDI parent, but behind the UserControl.

When I hit the submit button I want the entered data to appear in textboxes on groupForm, but this isn't happening. I have to restart the form or hit the Refresh button for the data to appear.[code]...
I added groupForm.populate() at the end of the latter function for testing purposes, but I know that shouldn't be necessary ("populate" just loops over all items in the ProfitObjects array and calls NewProfitObjectsItem for each one).
Anyway; when I submit the data from the second form, the groupForm doesn't automatically show the new data. I either have to hit the refresh button or restart the form (it calls populate() on form load).
I simply want the new item to appear immediately after Submitting it. And it should, because that's what groupForm.NewProfitObjectsItem() does. And to top it off I added groupForm.populate(). I'm assuming it's not working because it's called from an external form, or because the other form is open/has the focus.

At the moment, I'm writing tons of custom control, which all fits my needs. But the thing is, each time I Debug the project, it doesn't update the form designer at all, not even the code. My solution to this is to Rebuild the project, which can take time. This is very frustrating.
I'm using Microsoft Visual Studio 2010 Ultimate to compile.

I 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.

I'm just getting started in VBE 2008 porting a VB6 program and have created the MDI Parent form. I've added a form called frmNav and need to designate this and all subsequent forms as MDI child forms. Is there somewhere in each form's properties where I designate this? It used to be in VB6 there was a property called "MDIChild = True." input id="gwProxy" type="hidden"><!-- Session data--></input> <input id="jsProxy" onclick="jsCall();" type="hidden" />

I have a regular form that I have a SplitContainer on and I would like to launch an external program (not mine) in Panel2, maximize it to fill the whole panel, and hide it's toolbar if possible. The program I am launching is a monitoring program of network activity. To be even more detailed, it is a puTTy window that opens a telnet connection to a server. I need to launch this putty window in Panel2, and then maximize it so that it cannot be resized/dragged.

I have a slight problem With an enumaration of child controls on a form. The following code will not get but about have the controls that are on the form. The controls show that the count is correct but when it goes through the loop it skips over some of the controls. If you run it through the enumeration two or three times it will get all the controls a few at a time. The solution uses two forms, one that has the controls and the other that labels are made and displayed on. The Tx is just a index to add a number to the label.name and rename the label. So each label is identified seperately. This works for all the the controls that are seen in the for each loop.
