Gets or sets the value associated with this cell.

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

[BrowsableAttribute(false)]
public object Value { get; set; }

Property Value

Type: System.Object

Gets or sets the data to be displayed by the cell. The default is null.

Exception Condition
ArgumentOutOfRangeException

RowIndex is outside the valid range of 0 to the number of rows in the control minus 1.

InvalidOperationException

ColumnIndex is less than 0, indicating that the cell is a row header cell.

When you assign a different value to a cell, the CellValueChanged event of the DataGridView control is raised.

The Value property is the actual data object contained by the cell, whereas the FormattedValue property is the formatted representation of the data. The ValueType and FormattedValueType properties correspond to the data types of these values, respectively.

When you set the Value property, the specified value is not automatically converted from a formatted, display value to an underlying cell value. For example, the DataGridViewCellStyle in effect for the cell is ignored, so setting Value to DataGridViewCellStyle.NullValue does not result in a property value of DataGridViewCellStyle.DataSourceNullValue.

The following code example shows how to update a cell's contents with the Value property. This example is part of a larger code example provided in How to: Manipulate Rows in the Windows Forms DataGridView Control.

// Give cheescake excellent rating.
private void Button8_Click(object sender,
    System.EventArgs e)
{
    UpdateStars(dataGridView.Rows[4], "******************");
}

int ratingColumn = 3;

private void UpdateStars(DataGridViewRow row, string stars)
{

    row.Cells[ratingColumn].Value = stars;

    // Resize the column width to account for the new value.
    row.DataGridView.AutoResizeColumn(ratingColumn, 
        DataGridViewAutoSizeColumnMode.DisplayedCells);
}
