DataGridView Windows Forms control

The DataGridView Windows Forms control is a quite new .NET control introduced in MS Visual Studio .NET 2005 that is a good alternative to the VS .NET 1.x DataGrid control. The data table presentation feature became much easier to be implemented in .NET Windows application. The most attractive features of the new control are:
It allows to mix both data bound and unbound, virtual columns in the GridView.
It has a special virtual mode allowing to actually display more than 100 000 rows without a huge performance hit.
It gives ability to easily apply styles to individual columns, rows, cells, or an entire data source table.

DataGrid Windows Forms control

Obviously we do not need to disregard the .NET DataGrid control. For most situations it works faster than the new DataGridView. Also the control gives you ability to display hierarchical data. This is a big advantage of DataGrid .NET Windows Forms control.
In Visual Studio .NET 1.x, the DataGrid control is not easy to be used in .NET Windows application. A quantity of jobs you may want to achieve with the Windows Forms DataGrid control are, unexpectedly, more troublesome than you might expect. Principally, this is because the Windows Forms DataGrid control is column-based, rather than cell-based. As a result, to attain most tasks, you have to work with the columns, not the cells themselves.
DataGridColumns .NET assembly from Rustemsoft LLC is a DataGrid Columns Styles software package specifically designed for .NET developers. The assembly allows you to use all strengths of the MS Windows .NET forms DataGrid control without waiving the user interface elements your customers need.

VB .NET

Private Sub AddDataGridColumn()
Dim dataset As New DataSet
' Put some actions to populate the dataset
Dim TblStyle As New DataGridTableStyle
With TblStyle
' Set column style
With .GridColumnStyles
' Set datagrid ComboBox ColumnStyle for PubID field
.Add(New DataGridComboBoxColumn(dataset.Tables.Item("Companies"), 1, 0))
With .Item(0)
.MappingName = "PubID"
.HeaderText = "Company ID"
.Width = 150
.NullText = String.Empty
End With
End With
End With
' Add TableStyle
DataGrid1.TableStyles.Add(TblStyle)
End Sub


C#

private void AddDataGridColumn()
{
DataSet dataset = new DataSet();
// Put some actions to populate the dataset
// Set column style
DataGridTableStyle TblStyle = new DataGridTableStyle();
// Set datagrid ComboBox ColumnStyle for PubID field
DataTable tblCompanies = dataset.Tables["Companies"];
TblStyle.GridColumnStyles.Add(new DataGridComboBoxColumn(ref tblCompanies, 1, 0, true, false, true, DataGridComboBoxColumn.DisplayModes.ShowDisplayMember,0));
TblStyle.GridColumnStyles[0].MappingName = "PubID";
TblStyle.GridColumnStyles[0].HeaderText = "Company ID";
TblStyle.GridColumnStyles[0].Width = 150;
TblStyle.GridColumnStyles[0].NullText = string.Empty;
// Add TableStyle
DataGrid1.TableStyles.Add(TblStyle);
}


The above example creates a DataGridComboBoxColumn and adds it into DataGrid TableStyle.

DataGridView Columns .NET 3.5 assembly

In the new MS Visual Studio .NET 2005, the DataGridView control provides a visual table layout for displaying data. All DataGridView control designing operations are just dragging and dropping into the IDE design layout window. The DataGridView .NET 3.5 control seems a lot better than DataGrid .NET 1.x control. It provides a powerful and flexible way to display a data source. You can extend the DataGridView control in a number of ways to build custom behaviors into your applications. Although you can create your own types of cells the Windows Forms DataGridView control is mostly column-based, rather than cell-based. As a result, to attain most tasks, you have to work with the columns, the same way like with the DataGrid control.
DataGridViewColumns .NET assembly from Rustemsoft LLC is a DataGridView Columns software package specifically designed for .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.

DataGridViewColumns dynamic link library contains the following DataGridView Columns: Combo (extended combobox), Memo column, DateTimePicker column. Also the assembly includes the formatting intelligent DateTimeColumn, NumericColumn, TextFractionsColumn, MaskedTextBox column controls that can mask the date, time, numbers as well as the text fractions. It gives you ability to manage the IP Address, SS#, Phone numbers, etc., and checks the validation, and automatically set the delimiter location. These Column classes are chock full of functionality that you will not find in the standard Microsoft .NET 2.x DataGridView Columns, that make it easy to build professional and forcing user interfaces.

VB .NET

With DataGridView1
' Set DataGridView Combo Column for CarID field
Dim ColumnCar As New DataGridViewComboColumn
' DataGridView Combo ValueMember field has name "CarID"
' DataGridView Combo DisplayMember field has name "Car"
With ColumnCar
.DataPropertyName = "CarID"
.HeaderText = "Car Name"
.Width = 80
' Bind ColumnCar to Cars table
.box.DataSource = ds.Tables("Cars")
.box.ValueMember = "CarID"
.box.DisplayMember = "Car"
End With
.Columns.Add(ColumnCar)
End With


C#

// Set DataGridView Combo Column for CarID field
DataGridViewComboColumn ColumnCar = new DataGridViewComboColumn();
// DataGridView Combo ValueMember field name is "CarID"
// DataGridView Combo DisplayMember field name is "Car"
ColumnCar.DataPropertyName = "CarID";
ColumnCar.HeaderText = "Car Name";
ColumnCar.Width = 80;
// Bind ColumnCar to Cars table
ColumnCar.box.DataSource = ds.Tables["Cars"];
ColumnCar.box.ValueMember = "CarID";
ColumnCar.box.DisplayMember = "Car";
// Add ColumnCar onto DataGridView layout
DataGridView1.Columns.Add(ColumnCar);


The code above presents DataGridViewCombo Column usage

Extended DataGridView columns

The DataGridView control properties can be customized and the control object can be linked with or without an assigned DataSource object. The .NET Framework (2.0 and later) includes six types of DataGridView column classes by default: DataGridViewButtonColumn, DataGridViewCheckBoxColumn, DataGridViewComboboxColumn, DataGridViewImageColumn, DataGridViewTextBoxColumn, and DataGridViewLinkColumn classes. Rustemsoft LLC DataGridViewColumns 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 DomainUpDown Column
DataGridView NumericUpDown Column
DataGridView Picture Column
DataGridView MaskedTextBox Column
DataGridView Print Class

The DataGridViewPrint service class is intended to help you to create a print output based on your DataGridView content. The class has been included into the assembly since it is build for .NET WinForms DataGridView control and very helpful for your .NET DataGridView design. It will help you to implement an application with a print preview and a print support.
The DataGridViewPrint class is used by the Print dialog and DataGridViewPrintPreview dialog (on your .NET form) to draw the DataGridView object content that should be printed. An object of the class is used for a .NET PrintDocument object.


Also the special DataGridViewPrintPreview class has been designed and added to the assembly. The class gives the ability to print DataGridView content by clicking ?Print? button located on the dialog window. Also ?Save to file? button is added onto Preview dialog layout. It allows you to save the print document into a bitmap image file. Learn more about DataGridViewPrint service class
