After clear/Null dateTimePicker once date time not showing again means not working again

C#

private void radioButton11_CheckedChanged(object sender, EventArgs e)
{
   //Both lines are not working after clear/null dateTimePicker once          
    dateTimePicker1.Value = DateTime.Now; 
    dateTimePicker2.ResetText();
}

private void radioButton12_CheckedChanged(object sender, EventArgs e)
{
    dateTimePicker1.CustomFormat = " ";
    dateTimePicker2.CustomFormat = " ";
}

What I have tried:

C#

private void radioButton11_CheckedChanged(object sender, EventArgs e)
{
   //Both lines are not working after clear/null dateTimePicker once          
    dateTimePicker1.Value = DateTime.Now; 
    dateTimePicker2.ResetText();
}
private void radioButton12_CheckedChanged(object sender, EventArgs e)
{
    dateTimePicker1.CustomFormat = " ";
    dateTimePicker2.CustomFormat = " ";
}

That's know/faced by few, look here[^].

This is because you are setting it to null and resets to bad format.

Following has been shared working across:

Quote[^]:
Logic is to reset date to minimum and then use ValueChanged event to hide it in display using what you already tried.

C#

private void DateTimePicker1_ValueChanged(object sender, EventArgs e)
{
    if (dateTimePicker1.Value == DateTimePicker.MinimumDateTime)
    {
        dateTimePicker1.Value = DateTime.Now; // This is required in order to show current month/year when user reopens the date popup.
        dateTimePicker1.Format = DateTimePickerFormat.Custom;
        dateTimePicker1.CustomFormat = " ";
    }
    else
    {
        // Set the format that you want it in. For example, Short set here. 
        dateTimePicker1.Format = DateTimePickerFormat.Short;
    }
}

private void Clear_Click(object sender, EventArgs e)
{
    dateTimePicker1.Value = DateTimePicker.MinimumDateTime;
}
