Arrow click event

[konrad]

Hi,

I need to know when user used arrows for changing value.

Create new project, drop RadDateTimePicker, double click on form to create Load and paste this code:

private void Form1_Load(object sender, EventArgs e)
{
    radDateTimePicker1.Format = DateTimePickerFormat.Time;
    radDateTimePicker1.ShowUpDown = true;

    radDateTimePicker1.MouseDown += radDateTimePicker1_MouseDown;
    radDateTimePicker1.DateTimePickerElement.MouseDown += DateTimePickerElement_MouseDown;
    radDateTimePicker1.DateTimePickerElement.TextBoxElement.MouseDown += TextBoxElement_MouseDown;
    radDateTimePicker1.ValueChanged += radDateTimePicker1_ValueChanged;
}

void radDateTimePicker1_ValueChanged(object sender, EventArgs e)
{
    Console.WriteLine("value changed: " + radDateTimePicker1.Value);
}

void TextBoxElement_MouseDown(object sender, EventArgs e)
{
    Console.WriteLine("radDateTimePicker1.DateTimePickerElement.TextBoxElement");
}

void DateTimePickerElement_MouseDown(object sender, EventArgs e)
{
    Console.WriteLine("radDateTimePicker1.DateTimePickerElement");
}

void radDateTimePicker1_MouseDown(object sender, MouseEventArgs e)
{
    Console.WriteLine("radDateTimePicker1");
}

Only radDateTimePicker1_MouseDown work when you click on arrow but this occurred after radDateTimePicker1_ValueChanged.
I my case i need to know when user clicked arrow before changing value.

I also try to add this event

radDateTimePicker1.DateTimePickerElement.ArrowButton.Click += ArrowButton_Click;

... but ArrowButton object is null.

Please give me some advice how to check if user click arrows before value was changed.

Hello Dominik,

Thank you for writing.

You can get the Up/Down buttons in this way:

RadDateTimePickerSpinEdit spinEdit = radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerSpinEdit;
RadRepeatArrowElement upButton = spinEdit.ButtonsLayout.Children[0] as RadRepeatArrowElement;
RadRepeatArrowElement downButton = spinEdit.ButtonsLayout.Children[0] as RadRepeatArrowElement;

upButton.Click+=...

I hope this helps. Regards,

Hello Peter,

Thank you for writing.

'Telerik.WinControls.UI.RadDateTimePickerSpinEdit' does not contain a definition for 'ButtonsLayout' and no extension method 'ButtonsLayout' accepting a first argument of type 'Telerik.WinControls.UI.RadDateTimePickerSpinEdit' could be found (are you missing a using directive or an assembly reference?)

In reference i have:
Telerik.WinControls
Telerik.WinControls.UI
TelerikCommon

Version: 2012.3.1017.40

Hi Dominik,

I am sorry for the inconvenience. For your version the relevant code is:

RadDateTimePickerSpinEdit spinEdit = radDateTimePicker1.DateTimePickerElement.GetCurrentBehavior() as RadDateTimePickerSpinEdit;
RadRepeatArrowElement upButton = spinEdit.DateTimePickerElement.Children[2].Children[2].Children[0] as RadRepeatArrowElement;
RadRepeatArrowElement downButton = spinEdit.DateTimePickerElement.Children[2].Children[2].Children[1] as RadRepeatArrowElement;

Let me know if you have further questions.
Kind regards,
