Create a custom Data Grid from Silverlight - c#

I'm watching at this page:
http://leeontech.wordpress.com/2010/02/01/summary-row-in-datagrid/
But they're using silverlight. I'm trying to create that user control to use it in a WPF C# application. I mean, not using Silverlight. But I can't find the namespaces: GroupHeader
I'm having a hard time with this. Thanks in advance.

Okay listen, you can totally do this, and in some scenarios I even recommend it.
Using a CollectionViewSource you can easily group your data. In the HeaderTemplate you can even use an Expander (or make your own) and get the animation you might be wanting. Here's a link to a sample of this: http://jerrytech.blogspot.com/2010/06/wpf-data-presentation-step-by-step.html
Using an ItemsControl, you can easily present your groups and details. In the ItemTemplate you can use styles make this look like a grid (if that is really what you want). You can also shift the style based on the type if your collection has more than one type of object in it (eat that datagrid!).
You can wire up your column headers (which will really be custom objects, right?) and handle all the sorting and stuff like that. They will look just right! Not like datagrid WinForm column headers!
Here's what's hard (not impossible, but more coding).
User-resizable columns.
User-rearrangable columns.
New record using bottom, empty row.
Paste from Excel (doesn't work right in datagrid either).
Select Row, highlight Column header.
That's it.
In lots of situations, this is really nice.
For the most part, I cannot stand the datagrid. Too restricting on UX.

I don't think you're not going to be able to get a silverlight control working in WPF.
Adding a footer row to the WPF datagrid is something a lot of people have complained about; it's ridiculous that it wasn't included out of the box.
See this thread from MSDN
Having been through this myself, your best bet will probably be to bite the bullet and use a third party control. It sucks, I know.

WPF Control Identification

Sorry but I am a newbie to WPF, I would really appreciate if you could help me-
Tag 1 in pic- Which control can I use to create a menu similar to that in the picture ? The closest I came was using a gridview within a listview but that ends up using a header for the gridview. Normal listview just highlights the entire strip and doesn't look good at all.
Tag 2 in pic // (No longer relevant, sorry)
Edit:
Looking for something simple like when using gridview with listview (as in pic below) there is automatically that standard window gradient & bevel effect etc. (As an idea, implementing it with buttons seems to cumbersome, first strip button border, then create all these effects.) So essentially anything already inbuilt in WPF.
Thanks for any help :-D !!!
ListBox or ListView are good controls to use. If it's just the 'pretty' factor you don't like, you can provide Templates to change the appearance. But functionally, ListBox and ListView provide the function of that menu.
When working with WPF, that should be your primary motivation when choose controls. What FUNCTIONS the way you want. You can always make it LOOK different with Templates, but getting the right FUNCTION is the primary goal for the control.

ListView with TreeViewItems in xaml

I'm pretty new to c#, the first thing that I'm trying to make is a ListView with data bindings which has turned out ok.
I'm now trying to make items have a twist button if the underlying model has any children (like the TreeView). Each of the children will have columns the same as all the top level items.
How would I go about doing this? Is there an already existing control like this? If not would I be better off dressing up a TreeView to look like a ListView, or dress up a ListView to look like a TreeView?
I went down the road outlined in this solution which dresses up a TreeView, but the end result looks pretty awful and the heading is actually just an item, so you lose all the nice column sizing and column buttons that can hook up to column sorting that you get in ListView so that route actually seems like it would be more work.
I noticed the new task manager has a control exactly like what I'm trying to create, I don't know how this made? probably in C though.
Microsoft provides a sample that appears to be what you are looking for. A write-up of the example can be found here:
http://msdn.microsoft.com/en-us/library/vstudio/ms771523(v=vs.90).aspx
When you build and run the example you will end up with something resembling this:
There is a large amount of templating done in the example, so you will be able to make things look the way you want.
What you describe sounds a bit like a TreeListView, and if you google 'WPF TreeListView' you will see some solutions that might be good for you. I have used one from Telerik, but it might be overkill depending on how complicated your needs are.
If you only want one sub-level like the image you attached, you might want to just roll your own using a ListView with a complex DataTemplate for the first column which would show an expander button and a simple ListBox bound to the children items.
Similar to the answer here, except your cell would have a checkbox styled to look like the arrow, the text for the item, and a child ListBox. Then bind the visibility of the child ListBox to the state of the checkbox.

ASP.net ListView with groups

I can't seem to find a good answer for this. I'm trying to set up a webpage to grab data from a database and display it something like:
username1
image1.jpg
imagename
image2.jpg
imagename2
username2
image3.jpg
imagename3
username3
image4.jpg
imagename4
image5.jpg
imagename5
image6.jpg
imagename6
There is a username, and with that username there is one or more images and image names. Not all the usernames will have the same number of images.
My question is, what is the best way to do this? I am able to accomplish this using a repeater control with a nested repeater. It's messy but works.
From what I've read, a ListView should be able to do the same thing but much cleaner. My problem with a ListView is that I have to set the GroupItemCount, it's not dynamic like i need. I think I can nest another ListView, but it turns out to be as much code as using a repeater.
Is one of these methods (repeater or listview) preferred over the other. Or is there a better way to do this that i'm not thinking of? I don't think that what i'm trying to do is out of the ordinary, so I think there would be a quicker way. To me, it seems much easier to do this in classic asp using for loops.
Thanks in advance for any input.
The GroupTemplate is instantiated when a certain number (GroupItemCount) of ItemTemplate are instantiated. The ItemTemplate is called for each object in the collection and you first have a collection of users. Even if you can change the GroupItemCount during the ItemDataBound event, this will reflect how the next group of users is created. There is nothing about images until now, so I can say that you can't use ListView for a such task.
Using a repeater inside the ItemTemplate of the main Repeater (or ListView if you want) is the best choice, also common, so you don't have to worry about the mess, another developer will easily see your intention.

How can I have my listbox have columns?

I want my ListBox to have columns, and one of those columns have to be a clickable URL.
How can I achieve this?
You can't do it in a ListBox. You can create your own control, or settle for another existing one. Based on the question, I'd guess you're not yet at the stage where you're creating your own controls. That takes a pretty good understanding of existing controls and the way they work under the covers (but a google search for creating Winforms Controls should yield plenty of instructions.) Edit added It looks like te 4th and 5th links in combination on that google search should get you what you need. You can create your own user control and then do an array of them)
As far as for other possible alternatives, have you considered a DataGridView? A DataGridView can have a hyperlink and it can have checkbox columns, so this would be one possible alternative.
Here's a link for having a Hyperlink column in a DataGridView.
Well, it is possible by using the CustomTabOffsets property (unreliable) or the DrawItem event. And implementing the MouseDown event to find out if that particular 'column' was clicked.
But there's little point, a ListView control with View = Details gives you the same functionality.

Data templates in WinForms

I'm trying to have a grid that has items that have a custom layout/feel. If you have a look at the following http://mdavey.files.wordpress.com/2007/05/ldmain.jpg this is kinda what I am trying to do (see the aqua/red pods on the left and the graphs on the bottom right).
Under WPF/ASP.Net I would know how to do this but in WinForms I have no idea (I have never had to work on a WinForms app before). Like in WPF I would use Data Templates.
Hence I was wondering anyone knows of any good resources that goes through this or if anyone knows if its just as easy as creating a custom control, they having a grid that has one column and setting the type of that column to the custom control and then binding the data source to the grid???
Cheers Anthony
You may check Essential Grid - it seems to me it supports features you need.
There is an example for progress bar cell which you could use for the graphs on the right side:
http://www.syncfusion.com/products/user-interface-edition/windows-forms/grid/progressbar-cell
And they have Push Button cell type which you could use for your pods on the left side:
http://www.syncfusion.com/products/user-interface-edition/windows-forms/grid/push-button
You might also check DevExpress XtrGrid:
http://www.devexpress.com/products/net/controls/winforms/grid/dataediting.xml
http://www.devexpress.com/products/net/controls/winforms/grid/appearance.xml
In any case, I would search for a component - it takes quite a lot of time to do such things from the scratch.
