SpinEditor - Null Text

[Doug]

Is there a way to clear the value in a SpinEditor?  I want to be able to press the delete key and clear the value from the textbox and also programmatically clear it.  Something like what you showed me for a DateTimePicker:

dtpFilter1.NullableValue = null;
dtpFilter1.NullDate = System.Convert.ToDateTime("01/01/0001");
dtpFilter1.NullText = "";

//and

dtpFilter1.SetToNullValue();

Thank you,
Gary

Hi Gary,

Thank you for the question.

You should handle the KeyDownEvent and clear the text from the hosted TextBoxItem. Please, refer to the code below:

private void Form1_Load(object sender, EventArgs e)
{
    this.radSpinEditor1.SpinElement.TextBoxItem.NullText = "NULL TEXT";
    this.radSpinEditor1.KeyDown += new KeyEventHandler(radSpinEditor1_KeyDown);
}

void radSpinEditor1_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyData == Keys.Delete)
    {
        this.radSpinEditor1.SpinElement.TextBoxControl.Text = "";
    }
}

private void radButton1_Click(object sender, EventArgs e)
{
    this.radSpinEditor1.SpinElement.TextBoxControl.Text = "";
}

Bear in mind that the control will display the Null Text only if it does not contain focus.

I hope this helps. Regards,
