Is there any particular reason that you are using the WinForms DataGridView? WPF has got a DataGrid, which is fully compatible with data binding. You could have a property(call it SelectedCategory) in your viewmodel/codebehind which holds the selected category(bound to the SelectedItem property of the TreeView), and bind the DataGrid to SelectedCategory.Products. You then create a DataTemplate for the DataGrid which will show the particular properties of each product such as name, retail price etc.

See, I have strong restriction for my project to run under .NET version 3.5
It has no DataGrid control included. That's why I have to use DataGridView.

The WPF Toolkit[^] on CodePlex has a DataGrid which is compatible with .Net 3.5. If you don't like that option, the WPF ListView can be used with the View property set to Grid, and with some styling can be a very good alternative to a 'proper' DataGrid. Personally, I would use one of those options as opposed to the WinForms DataGridView.

Thanks a lot, Wayne.
Unfortunately I can't use any additional install packages for deployment. I'm just targeted on .NET 3.5 I will check the way to use ListView!

If someone has further ideas please welcome!

Unfortunately I couldn't find the way how to bind ListView to DataSet using the current selection of TreeView. Could you please provide simple example?

I don't really use datasets in my applications. I tend to prefer dealing with collections of CLR objects. Say I wanted to display a list of Customers in a ListView, and to have the details of the customer that is selected shown in other controls on the form for editing, I would bind my ListView to an ObservableCollection<Customer> property, and then bind the SelectedItem of the ListView to a SelectedCustomer Property in my ViewModel.

Tutorial to display Google Maps using WPF-WCF

Hi,

I am a beginner in developing C# applications

I want to develop a simple application to display Google Maps through a WPF/WCF application in VS 2010.

Can anyone provide a simple tutorial on this or is it already out there?

For. example: maybe a video or written instructions?

Also, is it more easier to display Bing map in a WPF app than Google maps?

Thanks!

Round corner border not that easy

Image of the troubling border

Hi

I'm trying for over 2 days now to create toggle button that in pressed state looks like the above image, but that upper border is giving me a headache. Does anyone have any idea how to create that round corner that slightly goes down? The background is a linear gradient top to bottom: #b8c7d6 - #a8b3c4

Any help at all would be greatly appreciated!!

I have something like this but it is far from the design:

A Combobox size within menu [modified]

Hello. After a long time i again pick WPF. Since this is nearly a hobby, i didn't learn much or forgot about it.

HTML

<Menu DockPanel.Dock="Top">
        <ComboBox  IsEditable="False" Width="{Binding Path=ActualWidth, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=Menu}}"></ComboBox>
</Menu>

I tried that. I Wanted ComboBox to use a size to take all spaced that shows menu. But in my case. It is a little to big. I do not wan't to explictly define the width of ComboBox. Can someone help me?

Thank you in advance.

Edit:

I used SizeChanged on a menu and used the folowing.

comboBoxProcessList.Width = (Double)((Menu)sender).ActualWidth - 15;

I do not like the current solution. It would be best if it was possible to do in xaml or if i could get the size of a ContentPresenter of the parrent element. In my case it is Menu

Connecting a C# Array to a Listbox Control 2 ways

MacAllen26-Aug-11 19:45

26-Aug-11 19:45

I've a struct called accounts (string account, int value), and a class called person with an arraylist of accounts (in C#).

I need the user to hit a button on the main window and have it bring up a listbox with SOME of the person.accounts (based on some criteria, it will vary, don't want to bury my question in code when all I need is an example), have the listbox show both the account and the value (so the whole struct, not just the account number, like "10456786 $75.50"), have the user double click on one of the accounts in the listbox and have logic execute to change the value of person.account.value for that specific account (increment up or down, I have that logic, I just don't know how to connect them).

I've been wrestling with this for a week now, digging through all the books I've managed to scavenge up (new to WPF, teaching myself), and just can't make this work. I have the pieces, but not how to connect them.

It doesn't have to be Listbox, at this point I'm open to suggestions, I'm just at my wit's end on figuring out how to do this.

Thank you in advance for your patience and consideration.

You can get the current item in the listbox using a CollectionViewSource.

Conditional Controls in WPF?

MacAllen26-Aug-11 19:34

MacAllen

26-Aug-11 19:34

Ancient programmer, self-teaching C# and WPF, going through books but a bit lost on this one thing:

I need buttons on my main window (doing the app in WPF as much as possible) to be present/absent based upon the values of the variables in a class.

For example, I have a class person, and it has a string called branch (so person.branch). If person.branch = "" (they've not chose a branch yet), then I need the Branch button to be available. Once they select a branch (person.branch != ""), I need the button to go away (greyed out is OK, gone is better).

Just need a small code snippet, and example to point me in the right direction and I'll research the rest.

Appreciate the help in advance, sorry to bother you.

If you are using INotifyPropertyChanged and the view / viewmodel concept, you can bind a property of the view model to the visibility.
For e.g.

Now its just setting this MyBranchProperty to the appropriate value in the view model.

Just a little advice from an old school programmer to another. I've learned that Binding is the only way to go with WPF. You will cause yourself more bugs, errors and headache trying to do it old school. Just step up and take the time to learn how to bind elements and such. Like I said just a friendly bit of advice.

WPF offers so much in the way of customization I sincerely hope Microsoft doesn't scrap it.

You can write converters (Branch(string) to Visibility converter) as well and bind it to the visibility!

Disappearing namespace? [modified]

Having an issue that is causing me to bang my head. my namespace is not being seen by the designer but still compiles and runs fine. the problem is that I can't view the forms at design time this happened shortly after I moved my files into folders to organize my program better. Yes I did make namespace modifications all throughout my app otherwise it wouldn't run. here is the main window xaml that is causing the error to occur.

HTML

these three give the error

xmlns:classes="clr-namespace:MHManager.Classes"
xmlns:controls="clr-namespace:MHManager.Controls"

Maybe this will help to figure this out. It only happens when I copy all the files and transfer them to my laptop to work on the project there. So on my desktop everything is fine, but after I open the project on my laptop the Designer displays this message:

Try using command Rebuild Soulution from Build menu. It will clean cache and build it again. Then try restarting visual studio. If those namespaces are in a diffrent project, then check references.

Edit: You also coud try to delete .suo file that lies in the same folder that has a solution file. That file resets Certan IDE elements, but does not break project/solution. This file has hidden attribute. You need special settings to see it.

Thanks I've tried cleaning and rebuilding the project/solution but I havn't tried deleting the .suo file.

Ok tried that and a few other things still get the same error and can't display design time window. Also it won't let me compile a release version like this although a debug version is fine.

What error does it throw when you compile release version. Maybe something is missing.

Maybe you should check the folowing:

ok now I can get it to build debug or retail on my desktop but my laptop gives me the error. Mind you it always been the laptop giving the error. Brand new Laptop 4gig ram, has the new AMD APU in it. What throws me is that it will compile and run in debug but not retail and the designer can't display my main form.

Yet, on my desktop it is fine. This is driving me nuts. As for the Library Controls links I reviewed them, I do have some custom controls in my project but have not been giving me any trouble as they are basically overridden controls. Extended RTF editor, Masked Text Box, etc.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
