✅ Problems adding usercontrol

I'm trying to add a usercontrol to a window. In the window I added the local reference liek this:

cs xmlns:local="clr-namespace:PrototipServer.Controls"

cs xmlns:local="clr-namespace:PrototipServer.Controls"

` And i have use it like this:

cs         <local:DataGridAlarmes x:Name="gd_Alarmes" estacioSeleccionada="gd_AlarmesSelectionChanged" Visibility="Hidden"  HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5,5,10,5" Grid.Column="2"  Grid.Row="2"/>

cs         <local:DataGridAlarmes x:Name="gd_Alarmes" estacioSeleccionada="gd_AlarmesSelectionChanged" Visibility="Hidden"  HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5,5,10,5" Grid.Column="2"  Grid.Row="2"/>

My usercontrol is inside a folder called controls inside the project. Does anyone know why it's not working?

The userControl is defined like this:

namespace PrototipServer.Controls
{
    /// <summary>
    /// Lógica de interacción para DataGridAlarmes.xaml
    /// </summary>
    public partial class DataGridAlarmes : UserControl
    {


        public DataGridAlarmes()
        {
            InitializeComponent();
        }

namespace PrototipServer.Controls
{
    /// <summary>
    /// Lógica de interacción para DataGridAlarmes.xaml
    /// </summary>
    public partial class DataGridAlarmes : UserControl
    {


        public DataGridAlarmes()
        {
            InitializeComponent();
        }

<UserControl x:Class="PrototipServer.Controls.DataGridAlarmes"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

To help you to get any answers: What is the actual error you are getting?

linuscoroOP•4mo ago

Error XDG0008 El nombre "DataGridAlarmes" no existe en el espacio de nombres "clr-namespace:PrototipServer.Controls". The name"DataGridAlarmes" dosn't exists in the namespace ...

qqdev•4mo ago

It says that the type does not exist in that namespace Yeah

linuscoroOP•4mo ago

linuscoroOP•4mo ago

As you can see it's there

qqdev•4mo ago

Are you using the control in the same project?

linuscoroOP•4mo ago

yes

qqdev•4mo ago

Or in a different one? Okay

linuscoroOP•4mo ago

i'm trying to use it in a window called Manteniment

linuscoroOP•4mo ago

and then i'm using it like this:

cs <controls:DataGridAlarmes x:Name="gd_Alarmes" Visibility="Hidden"  HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5,5,10,5" Grid.Column="2"  Grid.Row="2"/>

cs <controls:DataGridAlarmes x:Name="gd_Alarmes" Visibility="Hidden"  HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="5,5,10,5" Grid.Column="2"  Grid.Row="2"/>

qqdev•4mo ago

Does not look wrong to me Did you try rebuilding the project?

linuscoroOP•4mo ago

Yes. and also clean it and it gives me the same error all the time

qqdev•4mo ago

Hm, no clue then You could try to come up with a minimal example Create a new project + window + user control And replicate it If it works -> You are missing something If it does not work -> We have to take a closer look

linuscoroOP•4mo ago

Okey ty, i will try it now

qqdev•4mo ago

One more thing Did you also check the cs file of that user control? Make sure the namespace is correct there too

qqdev•4mo ago

Click the little arrow next to the xaml file Everything has to match to make this work

linuscoroOP•4mo ago

Yes i have check it. Also i created a new project with a blank usercontrol inside a folder called controls and then add it to the main window and im getting the same error. So i guess i'm doing something wrong when adding the usercontrol

qqdev•4mo ago

Let me try it quickly

linuscoroOP•4mo ago

okey

qqdev•4mo ago

Works for me ;D Can you share the contents of the files?

linuscoroOP•4mo ago

qqdev•4mo ago
