如何在keydown DataGridView C#中给出条件

Question

I want to make a condition like this

private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
{
}

If the user selects the first column it will execute insert and if they select the third column it will execute edit

How do I go about doing this?

Answer 1

Try this

if( dataGridView1.SelectedColumns[2] != null)
{
    //Insertion
}
if( dataGridView1.SelectedColumns[0] != null)
{
   //Editing
}

Answer 2

You need to check the selected columns, assuming they can only select one you can do this check

if(dataGridView1.SelectedColumns[0] == dataGridView1.Columns[0])
{
    //Insert code;
}

else if(dataGridView1.SelectedColumns[0] == dataGridView1.Columns[2])
{
    //Edit code;
}

If they can select multiple columns you should first do this check as well

if(dataGridView1.Columns.GetColumnCount(DataGridViewElementStates.Selected) == 1)
{
    if(dataGridView1.SelectedColumns[0] == dataGridView1.Columns[0])
    {
        //Insert code;
    }

    else if(dataGridView1.SelectedColumns[0] == dataGridView1.Columns[2])
    {
        //Edit code;
    }
}
