Providing support for loading the palette with the resource file.
Providing support for loading the palette with the resource file.
Syncfusion® Diagram supports the functionality of loading the palette with the resource file in PaletteGroupBar. To achieve that functionality, the PaletteGroupBar class must be customized, and the customized class must inherit from the PaletteGroupBar class.
The below code shows how to Customize the PaletteGroupBar class.
[C#]
class CustomPaletteGroupBar : PaletteGroupBar
{
public CustomPaletteGroupBar(): base()
{
}
}
[VB]
Friend Class CustomPaletteGroupBar Inherits PaletteGroupBar Public Sub New() MyBase.New() End Sub End Class
After customizing the PaletteGroupBar class The LoadPalette method of type PaletteGroupView must be defined.
The below code defines the LoadPalette method.
[C#]
public PaletteGroupView LoadPalette(Assembly assembly, string baseName, string resName)
{
PaletteGroupView paletteView = new PaletteGroupView();
paletteView.SelectedItem = -1;
paletteView.EditMode = this.EditMode;
paletteView.ButtonView = true;
paletteView.BackColor = Color.Ivory;
paletteView.Diagram = this.Diagram;
if (paletteView.LoadPalette(assembly,baseName,resName))
{
// Load succeeded.
GroupBarItem paletteBarItem = new GroupBarItem();
SymbolPalette symbolPalette = paletteView.Palette;
paletteBarItem.Text = symbolPalette.Name;
paletteBarItem.Tag = symbolPalette;
paletteBarItem.Client = paletteView;
this.GroupBarItems.Add(paletteBarItem);
}
else
{
// Load failed.
paletteView.Dispose();
paletteView = null;
}
return paletteView;
}
[VB]
Public Function LoadPalette(ByVal [assembly] As System.Reflection.Assembly, ByVal baseName As String, ByVal resName As String) As PaletteGroupView Dim paletteView As New PaletteGroupView() paletteView.SelectedItem = -1 paletteView.EditMode = Me.EditMode paletteView.ButtonView = True paletteView.BackColor = Color.Ivory paletteView.Diagram = Me.Diagram If paletteView.LoadPalette([assembly],baseName,resName) Then ' Load succeeded. Dim paletteBarItem As New GroupBarItem() Dim symbolPalette As SymbolPalette = paletteView.Palette paletteBarItem.Text = symbolPalette.Name paletteBarItem.Tag = symbolPalette paletteBarItem.Client = paletteView Me.GroupBarItems.Add(paletteBarItem) Else ' Load failed. paletteView.Dispose() paletteView = Nothing End If Return paletteView End Function
After customizing the PaletteGroupBar class the customized Palettegroupbar class must invoke the LoadPalette method and the resource file is passed as an argument.
The below code shows how to invoke the LoadPalette method and passing the resource file as an argument.
[C#]
customPaletteGroupBar1.LoadPalette(Assembly.GetExecutingAssembly(), "CustomPalette.Properties.Resources", "Circuit_Shapes");
[VB]
customPaletteGroupBar1.LoadPalette(System.Reflection.Assembly.GetExecutingAssembly(), "CustomPalette.Properties.Resources", "Circuit_Shapes")
