Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in

public DataGridViewEditMode EditMode { get; set; }

public DataGridViewEditMode get_EditMode ()

public void set_EditMode (DataGridViewEditMode value)

public function get EditMode () : DataGridViewEditMode

public function set EditMode (value : DataGridViewEditMode)

Property Value

One of the DataGridViewEditMode values. The default is EditOnKeystrokeOrF2.

Exception typeCondition


The specified value when setting this property is not a valid DataGridViewEditMode value.


The specified value when setting this property would cause the control to enter edit mode, but initialization of the editing cell value failed and either there is no handler for the DataError event or the handler has set the DataGridViewDataErrorEventArgs.ThrowException property to true. The exception object can typically be cast to type FormatException.

All DataGridViewEditMode values except for EditProgrammatically also allow a user to double-click a cell to begin editing it.

The following code example demonstrates how to initialize a simple data-bound DataGridView. It also demonstrates how to set the EditMode property. To run this example, paste the following code into a form that contains a DataGridView named dataGridView1, replace the value of the connectionString variable specified in the code with a string that is valid for the system the example will run on, and call the InitializeDataGridView method from the form's constructor or Load event handler.

private void InitializeDataGridView()
        // Set up the DataGridView.
        dataGridView1.Dock = DockStyle.Fill;

        // Automatically generate the DataGridView columns.
        dataGridView1.AutoGenerateColumns = true;

        // Set up the data source.
        bindingSource1.DataSource = GetData("Select * From Products");
        dataGridView1.DataSource = bindingSource1;

        // Automatically resize the visible rows.
        dataGridView1.AutoSizeRowsMode =

        // Set the DataGridView control's border.
        dataGridView1.BorderStyle = BorderStyle.Fixed3D;

        // Put the cells in edit mode when user enters them.
        dataGridView1.EditMode = DataGridViewEditMode.EditOnEnter;
    catch (SqlException)
        MessageBox.Show("To run this sample replace connection.ConnectionString" +
            " with a valid connection string to a Northwind" +
            " database accessible to your system.", "ERROR",
            MessageBoxButtons.OK, MessageBoxIcon.Exclamation);

private static DataTable GetData(string sqlCommand)
    string connectionString = "Integrated Security=SSPI;" +
        "Persist Security Info=False;" +
        "Initial Catalog=Northwind;Data Source=localhost";

    SqlConnection northwindConnection = new SqlConnection(connectionString);

    SqlCommand command = new SqlCommand(sqlCommand, northwindConnection);
    SqlDataAdapter adapter = new SqlDataAdapter();
    adapter.SelectCommand = command;

    DataTable table = new DataTable();
    table.Locale = System.Globalization.CultureInfo.InvariantCulture;

    return table;
