Re: DataGridComboBoxColumn - Combo Doesn't Show

1-Apr-15 8:57

I'm trying to add a DataGridComboBoxColumn to my grid in the code behind:

public List<Person> People = new List<Person>();

People.Add(new Person { Id = 0, Name = "Joe" });
People.Add(new Person { Id = 1, Name = "Pete" });
People.Add(new Person { Id = 2, Name = "Sam" });

System.Windows.Controls.DataGridComboBoxColumn comboCol = new System.Windows.Controls.DataGridComboBoxColumn();
comboCol.Header = "People";
comboCol.ItemsSource = People;
comboCol.DisplayMemberPath = "Name";
comboCol.SelectedValuePath = "Id";
this.taskGrid.Columns.Add(comboCol);

When I run it, the column is added, but the combo does not appear in the row. What am I doing wrong here?

Thanks

If it's not broken, fix it until it is

Trying to add a combo to a datagrid! Sorry I just never allow inline editing of more than the absolute minimum and NEVER allow controls to be included in a datagrid.

Having said that why not include the column at design time and set the visibility of the column at runtime.

This is a really old question, it comes down to a server delivers responses to a request, it does not know who is asking so it cannot respond to a nothing! Polling is the most common solution to this problem.

Or you can implement messaging services, a nasty piece of work.

You are correct, there was a thread recently on sql server using the notifications, had a problem if there was no change in 36 hours. I believe SignalR is also such a framework from service to client, not database to service.

I have no faith in EF and have never worked successfully with it so I can't help there.

Build in 3.5 and look at the XAML in the designer; and see if you get the same error. This may not even be a 4.5 problem; on the surface, it looks like there is a problem with the "source" for an "image" (IMO... just a guess... no warranty).

WPF Image Edit Control Required

26-Mar-15 22:18

All,

I am looking for a control that allows modification of a floormap image.

As it stands the floormaps are cad based and BMPs too, but I want to be able to display them in WPF app and modify them (move walls, add pre-defined icons to it for phone points for example).

The intersoft hospital floor is something Id like to do for example but plan needs to be modifiable at runtime. I think that uses KML type files but not sure how to create them from a CAD image (is that possible?). And then how can they be modified in run-time?

Is this possible? Is there a better / easier file format to use for this project?

Its at the design stage so just getting an idea of how to do it! Confused | :confused:

Thanks

I use Microsoft Visio for drawing floor plans. Here's a link that may be useful if you wish to consider Visio and integrating it with WPF:

Unfortunately Microsoft tend to change their systems with each new release, so you (almost) have to start from scratch each time. The only thing for it is to plough through their documentation. I have to say that I did once post a query on a similar problem to their development forum, and got some very useful help from them.

zephaneas25-Mar-15 6:34

The problem is that all they've provided is the XAML for the start page. No code. It's referring to some resources that are internal to VS2010. And there's no real documentation that I can see.

Assuming it is documented somewhere on MSDN, you have to search quite hard to find it. You could always try the Microsoft developer forum and ask there.

Re: VS 2012 Start Page Problem

19-Mar-15 10:29

I upgraded a VS 2010 start page to 2010. At the top are 3 objects:

"New Project..."
"Open A Project..."
"Connect To Team Foundation Server"

In VS2010 these are ImageButtons. In VS2012 I can't figure out what they are. So I changed the buttons from:

<vs:ImageButton 
    x:Uid="ConnectToTSButton"
    Margin="15,2,15,2"
    Width="Auto"
    Content="Connect To Team Foundation Server"
    Style="{StaticResource linkStyle}"
    Visibility="{Binding Path=TeamFoundationClientSupported, Converter={StaticResource boolToVisibilityConverter}}"	
    Command="{x:Static sp:VSCommands.ExecuteCommand}" CommandParameter="Team.ConnecttoTeamFoundationServer"    ImageNormal="pack://application:,,,/Microsoft.VisualStudio.Shell.StartPage;component/Images/StartPage/ConnectToTFS.png"    ImageHover="pack://application:,,,/Microsoft.VisualStudio.Shell.StartPage;component/Images/StartPage/ConnectToTFSMouseOver.png"    ImagePressed="pack://application:,,,/Microsoft.VisualStudio.Shell.StartPage;component/Images/StartPage/ConnectToTFSMouseDown.png">
</vs:ImageButton>

to hyperlinks:

<TextBlock Grid.Row="0"
            Margin="10,2,15,2">

    <Hyperlink Command="{x:Static sp:VSCommands.ExecuteCommand}" 
                CommandParameter="Team.ConnecttoTeamFoundationServer">
                        
        <TextBlock Text="Connect To Team Foundation Server"
                    FontSize="14"
                    Foreground="{StaticResource linkColor}"/>
    </Hyperlink>

</TextBlock>

But the links are never enabled. I dropped in a button and wire it to the command, and it also is disabled. So the question is, what makes this command enabled?

You are trying to edit Visual Studio's start page?

I don't find any solid reason why to do so... Secondly, if you need help, please see the XMLNS for vs and look for what is provided there to make these buttons run. I would like to say, don't do it. Let it be the actual page.

I didn't ask you if you found a reason to do so.

Let me educate you a bit since you clearly don't know... Starting in VS 2010 MS introduced Start Page templates so developers could create their own start pages. It's a WPF user control and is easy to modify. But they did not provide templates for later versions of VS, so you have to use the 2010 template, which can be difficult.

Please, if you don't have a solution to the problem, don't responde.
