Layer Combobox tool

[Amremad]

Hello Every body :

i hope to fine any combox  tool like autocad layer combox tool .. to design my custom layer manger :: can i find it ??

[fieldguy]

That looks like a datagridview control with image and text columns.  I can't help with adapting it for the ribbon but there are plenty of posts here on that topic.

If you can use WPF, there is a way to get a list of layers with their properties (Color, IsOff...) :

using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.Windows.Data;

namespace MyNameSpace
{
    public partial class LayerManagerWindow
    {
        public DataItemCollection Layers { get; set; }

        public LayerManagerWindow()
        {
            InitializeComponent();

            Layers = Application.UIBindings.Collections.Layers;

            DataContext = this;
        }
    }
}

<Window x:Class="MyNameSpace.LayerManagerWindow"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d" d:DesignHeight="300" d:DesignWidth="300">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="Auto" />
        </Grid.RowDefinitions>
        <ComboBox ItemsSource="{Binding Layers}">
            <ComboBox.ItemTemplate>
                <DataTemplate>
                    <StackPanel Orientation="Horizontal">
                        <TextBlock Text="{Binding Color}" />
                        <TextBlock Text="{Binding Name}" Margin="7,0,0,0" />
                    </StackPanel>
                </DataTemplate>
            </ComboBox.ItemTemplate>
        </ComboBox>
    </Grid>
</Window>

sorry i didnt use wpf before .. and i didn't understand your answer 

so can you send me the code that working with this way and i will understand it after run it  🙂

Here is a WinForms version:

DataItemCollection layers = Autodesk.AutoCAD.ApplicationServices.Application.UIBindings.Collections.Layers;
var bs = new BindingSource(layers, null);
comboBox1.DataSource = bs;
comboBox1.DrawMode = DrawMode.OwnerDrawFixed;
comboBox1.DrawItem += (o, args) =>
{
 ICustomTypeDescriptor dataItem = layers[args.Index];
 PropertyDescriptorCollection properties = dataItem.GetProperties();
 var color = (Autodesk.AutoCAD.Colors.Color) properties["Color"].GetValue(dataItem);
 Rectangle bounds = args.Bounds;
 int itemHeight = bounds.Height;
 Graphics graphics = args.Graphics;
 args.DrawBackground();
 var rect = new Rectangle(bounds.Left + 1, bounds.Top + 1, itemHeight - 2, itemHeight - 2);
 graphics.FillRectangle(new SolidBrush(color.ColorValue), rect);
 graphics.DrawRectangle(new Pen(Color.Black), rect);
 graphics.DrawString((string) properties["Name"].GetValue(dataItem), args.Font, 
 new SolidBrush(args.ForeColor), bounds.Left + itemHeight + 6, bounds.Top + 1);
 args.DrawFocusRectangle();
};

Unfortunately, I haven't found a way to sort the layers by their name and I'm running out of time. You should iterate the layer table to construct your list and then sort it.

I cannot give up so easily, it's stronger than me:

DataItemCollection layers = Autodesk.AutoCAD.ApplicationServices.Application.UIBindings.Collections.Layers;
List<ICustomTypeDescriptor> list = layers.OfType<ICustomTypeDescriptor>().ToList();
list.Sort((a, b) => string.Compare(
    ((string) (a.GetProperties()["Name"].GetValue(a))), (string) (b.GetProperties()["Name"].GetValue(b)), StringComparison.CurrentCulture));
comboBox1.DataSource = list;
comboBox1.DrawMode = DrawMode.OwnerDrawFixed;
comboBox1.DrawItem += (o, args) =>
{
    ICustomTypeDescriptor dataItem = list[args.Index];
    PropertyDescriptorCollection properties = dataItem.GetProperties();
    var color = (Autodesk.AutoCAD.Colors.Color) properties["Color"].GetValue(dataItem);
    Rectangle bounds = args.Bounds;
    int itemHeight = bounds.Height;
    Graphics graphics = args.Graphics;
    args.DrawBackground();
    var rect = new Rectangle(bounds.Left + 1, bounds.Top + 1, itemHeight - 2, itemHeight - 2);
    graphics.FillRectangle(new SolidBrush(color.ColorValue), rect);
    graphics.DrawRectangle(new Pen(Color.Black), rect);
    graphics.DrawString((string) properties["Name"].GetValue(dataItem), args.Font, 
        new SolidBrush(args.ForeColor), bounds.Left + itemHeight + 6, bounds.Top + 1);
    args.DrawFocusRectangle();
};

thank you very much .. 

but i know this way ..   your combobox doesn't have click on every item like autocad combobox . 

i need when user click on color rectangle he can choose another color  like autocad combobox . i hope you understand me

so is WPF give what i want ???

[FRFR1426 · Accepted solution]

Yes, in WPF it's simpler to make this kind of custom controls. But I cannot explain WPF in a forum thread...

Here is an article on the WPF combobox: http://www.wpf-tutorial.com/list-controls/combobox-control/

You can also make your own control with a popup window like this: http://www.codeproject.com/Articles/27472/ColorComboBox

thank you very much 

i'm reading now about wpf

Just found the missing bit for the WinForms solution: http://stackoverflow.com/q/18521110/200443

[Amremad]

hi again 🙂

i was using  this line 

colorPicker1.SelectedIndex = colorPicker1.Items.IndexOf("Yellow");

before using the new combobox ..

no this code doesn't work becouse he search in item text , but the correct must searching in SelectedValue 

is there another easy way other than using loop ??

[Anonymous]

hi,

I would be very happy if you could provide me coding for C# to display the layer and control the layer by windows form application

[Mahass]

Thank you for this helpful code.

Please can you tell me how to show the layerManagerWindow in the ribbon?

Is it possible to do similar ribboncombo with specific elements (Color, checkbox,Text) for each combo item?
