I d go with this   private void myDataGridView SelectionChanged Object sender  EventArgs e        dgvSomeDataGridView ClearSelection          I don t agree with the broad assertion that no DataGridView should be unselectable   Some UIs are built for tools or touchsreens  and allowing a selection misleads the user to think that selecting will actually get them somewhere     Setting ReadOnly   true on the control has no impact on whether a cell or row can be selected   And there are visual and functional downsides to setting Enabled   false   Another option is to set the control selected colors to be exactly what the non-selected colors are  but if you happen to be manipulating the back color of the cell  then this method yields some nasty results as well

I fixed this by setting the Enabled property to false

If you don t need to use the information in the selected cell then clearing selection works but if you need to still use the information in the selected cell you can do this to make it appear there is no selection and the back color will still be visible  private void dataGridView SelectionChanged object sender  EventArgs e                foreach  DataGridViewRow row in dataGridView SelectedRows                        dataGridView RowsDefaultCellStyle SelectionBackColor   row DefaultCellStyle BackColor

This worked for me like a charm   row DataGridView Enabled   false   row DefaultCellStyle BackColor   Color LightGray   row DefaultCellStyle ForeColor   Color DarkGray     where row   DataGridView NewRow appropriate overloads

Use the DataGridView ReadOnly property  The code in the MSDN example illustrates the use of this property in a DataGridView control intended primarily for display  In this example  the visual appearance of the control is customized in several ways and the control is configured for limited interactivity   Observe these settings in the sample code      Set property values appropriate for read-only    display and limited interactivity dataGridView1 AllowUserToAddRows   false  dataGridView1 AllowUserToDeleteRows   false  dataGridView1 AllowUserToOrderColumns   true  dataGridView1 ReadOnly   true  dataGridView1 SelectionMode   DataGridViewSelectionMode FullRowSelect  dataGridView1 MultiSelect   false  dataGridView1 AutoSizeRowsMode   DataGridViewAutoSizeRowsMode None  dataGridView1 AllowUserToResizeColumns   false  dataGridView1 ColumnHeadersHeightSizeMode    DataGridViewColumnHeadersHeightSizeMode DisableResizing  dataGridView1 AllowUserToResizeRows   false  dataGridView1 RowHeadersWidthSizeMode    DataGridViewRowHeadersWidthSizeMode DisableResizing

I liked user4101525 s answer best in theory but it doesn t actually work  Selection is not an overlay so you see whatever is under the control  Ramgy Borja s answer doesn t deal with the fact that default style is not actually a color at all so applying it doesn t help  This handles the default style and works if applying your own colors  which may be what edhubbell refers to as nasty results   dgv RowsDefaultCellStyle SelectionBackColor   dgv RowsDefaultCellStyle BackColor IsEmpty   System Drawing Color White   dgv RowsDefaultCellStyle BackColor  dgv RowsDefaultCellStyle SelectionForeColor   dgv RowsDefaultCellStyle ForeColor IsEmpty   System Drawing Color Black   dgv RowsDefaultCellStyle ForeColor

I found setting all AllowUser    properties to false  ReadOnly to true  RowHeadersVisible to false  ScollBars to None  then faking the prevention of selection worked best for me   Not setting Enabled to false still allows the user to copy the data from the grid   The following code also cleans up the look when you want a simple display grid  assuming rows are the same height    int width   0  for  int i   0  i  lt  dataGridView1 Columns Count  i          width    dataGridView1 Columns i  Width     dataGridView1 Width   width  dataGridView1 Height   dataGridView1 Rows 0  Height  dataGridView1 Rows Count 1

you have to create a custom DataGridView     namespace System Windows Forms       class MyDataGridView   DataGridView               public bool PreventUserClick   false           public MyDataGridView                                protected override void OnMouseDown MouseEventArgs e                        if  PreventUserClick  return               base OnMouseDown e                         note that you have to first compile the program once with the added class  before you can use the new control   then go to The  Designer cs and change the old DataGridView to the new one without having to mess up you previous code   private System Windows Forms DataGridView dgv     found close to the bottom        private void InitializeComponent                 this dgv   new System Windows Forms DataGridView                to  respective   private System Windows Forms MyDataGridView dgv   this dgv   new System Windows Forms MyDataGridView
