Create a simple application with IntegerTextBox

You can create a Windows Forms application with IntegerTextBox using the following steps:

Create a project

Create a new Windows Forms project in Visual Studio to display the IntegerTextBox control.

Add control through designer

The IntegerTextBox 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:

Maximum and minimum value constraints

You can set the maximum and minimum values using the MaxValue and MinValue properties of IntegerTextBox.

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

this.integerTextBox1.NumberGroupSeparator = "/";
integerTextBox1.IntegerValue = 1238761534122;
this.integerTextBox1.NumberGroupSizes = new int[] { 5 };
Me.integerTextBox1.NumberGroupSeparator = "/"
integerTextBox1.IntegerValue = 1238761534122
Me.integerTextBox1.NumberGroupSizes = New Integer() { 5 }
