C# Set Color for 1 Cell in DataGridView-CodePudding

iam looking for a method to set the color specific only for 1 cell by clicking on it.

I build a Canteen Voter, which you can choice between 4 menues each day.

My DataGridView is connected to a database from which it receives all information and when you click on a cell it is also stored in the database for the logged-in user.

Now I would like to be able to color the cells individually when clicking.

So far I only found the SelectedCells property, but this actually only sets a color for "SelectedCells" when these cells lose focus again they are white again.

I would have liked them to be able to keep this color to make it even clearer to the user which dish he had just chosen.

CodePudding user response：

You should set DataGridViewCell.Style property.

Take a look at this example

private void DataGridView1_CellClick(object sender, DataGridViewCellEventArgs e)
{
    if (e.RowIndex < 0 || e.RowIndex == dataGridView1.NewRowIndex)
    {
        return;
    }
    var dataGridViewCellStyle = 
        new DataGridViewCellStyle(dataGridView1.DefaultCellStyle)
    {
        BackColor = Color.Gold
    };
    dataGridView1[e.ColumnIndex, e.RowIndex].Style = dataGridViewCellStyle;
}
