Create a simple application with WinForms Integer TextBox

You can create a Windows Forms application with WinForms Integer TextBox using the following steps:

Create a project

Create a new Windows Forms project in Visual Studio to display the WinForms Integer TextBox control.

Add control through designer

The WinForms Integer TextBox control can be added to an application by dragging it from the toolbox to a designer view. The Syncfusion.Shared.Base assembly reference will be added automatically:

Add control manually in code

To add the control manually in C#, follow the given steps:

1. Add the Syncfusion.Shared.Base assembly reference to the project:

2. Include the Syncfusion.Windows.Forms.Tools namespace.

   C#

   using Syncfusion.Windows.Forms.Tools;

   VB.NET

   Imports Syncfusion.Windows.Forms.Tools

3. Create an WinForms Integer TextBox instance, and add it to the window.

   C#

   IntegerTextBox integerTextBox1= new IntegerTextBox();
   this.Controls.Add(integerTextBox1);

   VB.NET

   Dim integerTextBox1As IntegerTextBox = New IntegerTextBox()
   Me.Controls.Add(integerTextBox1)

Maximum and minimum value constraints

You can set the maximum and minimum values using the MaxValue and MinValue properties of WinForms Integer TextBox.

C#

this.integerTextBox1.MaxValue = 9223372036854775807;
this.integerTextBox1.MinValue = -9223372036854775808;

VB.NET

Me.integerTextBox1.MaxValue = 9223372036854775807
Me.integerTextBox1.MinValue = -9223372036854775808

Number format

You can display the numbers in custom format using the NumberGroupSeparator and NumberGroupSizes properties of WinForms Integer TextBox.

C#

this.integerTextBox1.NumberGroupSeparator = "/";
integerTextBox1.IntegerValue = 1238761534122;
this.integerTextBox1.NumberGroupSizes = new int[] { 5 };

VB.NET

Me.integerTextBox1.NumberGroupSeparator = "/"
integerTextBox1.IntegerValue = 1238761534122
Me.integerTextBox1.NumberGroupSizes = New Integer() { 5 }
