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?

Parent Child Relation In Gridview (windows Application)?

Oct 12, 2009

I am developing a small windows application(vb.net).In that i want to have parent child relations in a gridview control. There are lots of examples available on this, but they are using two gridviews for that, but in my case i want the relation to be displayed in a single gridview control itself. When they click the + sign immediate row should populate child rows with it's own header(ie child rows has it's own header which is different from parent header). In my case parent row has 2 columns and child row has 4 columns.

.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.

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

frmmain = new mainform

In frmMain I am doing this

Jan 19, 2011

I 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.

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.

Javascript - Close Child Aspx Page If Gridview Index Is Changed On Parent Page?

Nov 17, 2011

I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.

I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

Asp.net - Displaying Different Pictures In GridView Depending On The Data?

Dec 14, 2011

I am creating a WEB report in Visual Studio 2010 in VB.net. The report needs to display a table (please see the attached image). I am thinking to use the GridView component which i think it's the most appropriate one to choose. In the database there are students' data and marks. I can't alter the database in any way and i have to use Visual Studio 2010 with VB.

What i need to do is to show 3 different pictures(for example) depend on the student's marks. I got the pictures file in PNGs but this can be flexible.For example, over 70 will be a Smile picture. over 60 will be the Normal face. and over 40 will be the picture with no smile. I bit difficult for me to explain but i hope u get my point.

So pls advice me how can i achieve this. I am quite a newbie to this pls put as detail as you can. if there is a choice between client and server side script, i prefer server side script. Data source can be flexible (sql, or linq or anything).

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.
