Quick Start

Installation

TabBarSplitterControl NuGet Package:

Install the Syncfusion.Shared.Base NuGet package (latest version):

Install-Package Syncfusion.Shared.Base -Version *

Or via .NET CLI:

dotnet add package Syncfusion.Shared.Base --version *

Note: Using * ensures the latest version is installed during restore.

Child Control NuGet Packages:

When using TabBarSplitterControl with child controls (GridControl, SfDataGrid, or any Syncfusion/framework control), install the required NuGet packages for those child controls. Reference the child control's references/getting-started.md file in the skills folder for specific NuGet package installation instructions.

Examples:

• For GridControl: Check syncfusion-winforms-grid-control/references/getting-started.md for NuGet installation
• For SfDataGrid: Check syncfusion-winforms-datagrid/references/getting-started.md for NuGet installation
• For any other control: Check syncfusion-winforms-{control-name}/references/getting-started.md for NuGet installation

Basic Implementation (C#)

using Syncfusion.Windows.Forms;
using Syncfusion.Windows.Forms.Grid;

// Create TabBarSplitterControl
TabBarSplitterControl tabBarSplitter = new TabBarSplitterControl();

// Create TabBarPages
TabBarPage page1 = new TabBarPage();
page1.Text = "Sheet1";

TabBarPage page2 = new TabBarPage();
page2.Text = "Sheet2";

// Add GridControls to pages
page1.Controls.Add(new GridControl());
page2.Controls.Add(new GridControl());

// Add pages to TabBarSplitterControl
tabBarSplitter.Controls.Add(page1);
tabBarSplitter.Controls.Add(page2);

// Add to form
this.Controls.Add(tabBarSplitter);

Basic Implementation (VB.NET)

Imports Syncfusion.Windows.Forms
Imports Syncfusion.Windows.Forms.Grid

' Create TabBarPages
Dim page1 As New TabBarPage()
page1.Text = "Sheet1"

Dim page2 As New TabBarPage()
page2.Text = "Sheet2"

' Add GridControls to pages
page1.Controls.Add(New GridControl())
page2.Controls.Add(New GridControl())

' Add pages to TabBarSplitterControl
tabBarSplitterControl1.Controls.Add(page1)
tabBarSplitterControl1.Controls.Add(page2)

Common Patterns

Pattern 1: Creating Multiple Named Pages

// Initialize TabBarSplitterControl
TabBarSplitterControl tabBarSplitter = new TabBarSplitterControl();

// Create multiple pages with descriptive names
TabBarPage income = new TabBarPage { Text = "Income" };
TabBarPage expenses = new TabBarPage { Text = "Expenses" };
TabBarPage summary = new TabBarPage { Text = "Summary" };

// Add GridControl to each page
income.Controls.Add(new GridControl());
expenses.Controls.Add(new GridControl());
summary.Controls.Add(new GridControl());

// Add all pages to control
tabBarSplitter.Controls.Add(income);
tabBarSplitter.Controls.Add(expenses);
tabBarSplitter.Controls.Add(summary);

// Add to form
this.Controls.Add(tabBarSplitter);

Pattern 2: Using Existing GridControl Instances

// Assume you have pre-configured GridControls
GridControl gridIncome = new GridControl();
GridControl gridExpenses = new GridControl();

// Configure grids (add data, formulas, etc.)
// ... grid configuration code ...

// Create pages
TabBarPage incomePage = new TabBarPage { Text = "Income" };
TabBarPage expensesPage = new TabBarPage { Text = "Expenses" };

// Add existing grids to pages
incomePage.Controls.Add(gridIncome);
expensesPage.Controls.Add(gridExpenses);

// Add pages to TabBarSplitterControl
tabBarSplitter.Controls.Add(incomePage);
tabBarSplitter.Controls.Add(expensesPage);

Pattern 3: VB.NET Implementation

' Create TabBarPages
Private IncomePage As New Syncfusion.Windows.Forms.TabBarPage()
Private ExpensesPage As New Syncfusion.Windows.Forms.TabBarPage()

' Configure pages
IncomePage.Text = "Income"
IncomePage.Controls.Add(Me.gridControl1)

ExpensesPage.Text = "Expenses"
ExpensesPage.Controls.Add(Me.gridControl2)

' Add to TabBarSplitterControl
tabBarSplitterControl1.Controls.Add(Me.IncomePage)
tabBarSplitterControl1.Controls.Add(Me.ExpensesPage)

Key Properties and Classes

TabBarSplitterControl

Purpose: Main container control that hosts TabBarPages

Key Members:

• Controls - Collection of TabBarPage objects
• Standard WinForms control properties (Location, Size, Dock, etc.)

TabBarPage

Purpose: Individual page within TabBarSplitterControl

Key Properties:

• Text - Page tab label
• Controls - Collection of controls within the page (typically GridControl)
• Standard WinForms control properties

Common Use Cases

1. Financial Data Workbook

Create separate sheets for Income, Expenses, and Summary with GridControls or SfDataGrids for each. Reference child control skill files for specific NuGet requirements.

2. Multi-Sheet Reports

Organize different report views in separate tabs with cross-references between sheets. Use appropriate child controls based on customer requirements.

3. Data Analysis Interface

Display multiple data grids with formulas that reference data across different pages. Check GridControl or SfDataGrid skill files for implementation details.

4. Spreadsheet-Like Applications

Build Excel-like interfaces where each tab contains a separate data grid or any Syncfusion/framework control.

5. Dashboard with Multiple Views

Create tabbed interface where each page shows different data visualization, grid view, or custom controls. Reference respective skill files for child control implementation.

Designer Integration Note

TabBarSplitterControl can also be added via Visual Studio Designer:

• Drag and drop from toolbox
• Use TabBarPageCollectionEditor for page management
• Edit option available in designer mode

Note: Claude cannot perform manual designer operations. For programmatic implementation, use the patterns and examples provided in this skill.

Next Steps

• For TabBarSplitterControl installation and setup: Read references/getting-started.md
• For TabBarSplitterControl code implementation: Read references/programmatic-implementation.md
• For child control integration (GridControl, SfDataGrid, or any control):
  • Reference the child control's references/getting-started.md file in the skills folder for NuGet package installation
  • Check the child control's reference files for proper configuration
  • Ensure child control is properly configured before adding to TabBarPages
