RustemSoft is presenting a software package for customizing your .NET Windows Forms DataGridView Columns. DataGridView Columns .NET assembly is a DataGridView Columns software package specifically designed for Windows Forms .NET developers. The assembly allows you to use all strengths of the MS Windows .NET forms DataGridView control without waiving the user interface elements your customers need. By using the assembly you can create your own set of DataGridViewColumn objects that defines custom column for the Windows Forms DataGridView control and add them to the GridColumnsCollection. A column is an object that defines what the column looks and behaves like, including such things as color, font, and the presence of controls that will handle linked field in a database with the use of a ComboBox, a DateTime format Box and other control. Also we have built .NET code samples that describe the concepts and techniques that you can use to build DataGridView features into your applications. The code examples show the various ways to manipulate DataGridView columns using properties of the DataGridViewColumn class. The .NET Framework (2.0 and later) includes six types of DataGridView column classes by default: DataGridViewButtonColumn, DataGridViewCheckBoxColumn, DataGridViewComboboxColumn, DataGridViewImageColumn, DataGridViewTextBoxColumn, and DataGridViewLinkColumn classes. DataGridView Columns dynamic link library contains the following DataGridView Columns: DataGridView Combo Column (extended combobox); DataGridView Memo Column; DataGridView DateTimePicker Column; DataGridView DateTime Column; DataGridView Numeric Column; DataGridView Text Fractions Column; DataGridView Label Column; DataGridView Calculator Column; DataGridView Time UpDown Column; DataGridView DomainUpDown Column; DataGridView NumericUpDown Column; DataGridView Picture Column; DataGridView MaskedTextBox Column; DataGridView Print Class.
