DataGridViewRow

You can access the rows by using the Rows collection

dgvDataGridView.Rows 


AllowUserToAddRows

If this is enabled a special row is added.
This row is included in the Rows collection



Hiding Rows

Can be very slow

objDataGridView.SuspendLayout 
objDataGridViewRow.Visible = False
objDataGridView.ResumeLayout


DataGridViewRowTemplate

Gets or sets the row that represents the template for all the rows.


Using a RowTemplate lets you create and initialise a DataGridViewRow for use as a template, including the row for new records if the AllowUserToAddRows property is true.


Useful if you are setting default values or a specific row height.



Adding Rows

Rows cannot be added to a DataGridView programmatically when the control is data bound.


Dim objDataGridViewRow As System.Windows.Forms.DataGridViewRow 

objDataGridView.Rows.Add()
objDataGridViewRow = objDataGridView.Rows(objDataGridView.Rows.Count -1)

objDataGridViewRow.Cells(0).Value = "first column"
objDataGridViewRow.Cells(1).Value = "second column"

objDataGridView.Rows.Add(New String() {"Parker", "Seattle"}) 


Alternating Row Shading

This enables you use style characteristics like foreground color and font, in addition to background color, to differentiate alternating rows.

DataGridView1.RowsDefaultCellStyle.BackColor = Color.Bisque 
DataGridView1.AlternatingRowsDefaultCellStyle.BackColor = Color.Beige

The styles specified using the RowsDefaultCellStyle and AlternatingRowsDefaultCellStyle properties override the styles specified on the column and DataGridView level, but are overridden by the styles set on the individual row and cell level.



Bulk Addition

Do not use BeginEdit and EndEdit



The following line does not work ??

objDataGridView.Rows.Add(objDataGridViewRow)
