How to create Diagram Builder in MAUI platform?

2 mins read

This 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 the 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 code below:

 

@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 parent values 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, add the required stylesheets to the project and reference them inside the index.html file.

<link href="_content/Syncfusion.Blazor/styles/material.css" rel="stylesheet" />
<link href="assets/dbstyle/diagrambuilder.css" rel="stylesheet" />
