How to create Diagram Builder in MAUI platform?
The article explains how to create a Diagram Builder in the MAUI platform.
Step 1:
Create a Basic MAUI sample with all the necessary assemblies. Refer to this Getting started documentation to create and configure a simple MAUI sample.
Step 2:
In the MainLayout.razor file, remove the Navigation menu and add the below code.
@inherits LayoutComponentBase <div class="page"> <main> <article class="content px-4"> @Body </article> </main> </div>
Step 3:
In the Index.razor file, add the required service, and bind the parent values using the OnAfterRenderAsync method as shown in the code below.
Razor:
protected override async Task OnAfterRenderAsync(bool firstRender)
{
await base.OnAfterRenderAsync(firstRender);
if (firstRender)
{
if (this.DiagramMain != null)
this.DiagramMain.Parent = this;
}
}
Step 4:
Create a root component that wraps the menu bar, toolbar, diagram, symbol palette, and property panel. To manage property changes and other interactions between the components, bind the values of the parent to the root component.
protected override async Task OnAfterRenderAsync(bool firstRender)
{
await base.OnAfterRenderAsync(firstRender);
if (firstRender)
{
if (this.MenuBar != null)
this.MenuBar.Parent = this;
if (this.Toolbar != null)
this.Toolbar.Parent = this;
if (this.DiagramContent != null)
this.DiagramContent.Parent = this;
if (this.DiagramPropertyPanel != null)
this.DiagramPropertyPanel.Parent = this;
if (this.LeftSideBar != null)
this.LeftSideBar.Parent = this;
if (this.OpenDialog != null)
this.OpenDialog.Parent = this;
}
}
Step 5:
After implementing all the components logic, we need to add the required stylesheets to the project and refer that inside the index.html file.
<link href="_content/Syncfusion.Blazor/styles/material.css" rel="stylesheet" /> <link href="assets/dbstyle/diagrambuilder.css" rel="stylesheet" />
