Calculator Control

[Martin]

Hi folks,

Is there a way for the calculator control to be permanently 'dropped down'? I want to be have a control on a form so it can be dragged around the screen. and have it permanently anchored to the form it is on.

Thanks folks.

Hi Martin,

Thank you for writing.

You can use the PopupClosing event to cancel the close operation and you can show the drop down when the form is loaded:

protected override void OnLoad(EventArgs e)
{
    base.OnLoad(e);
    radCalculatorDropDown1.CalculatorElement.PopupClosing += CalculatorElement_PopupClosing;
    radCalculatorDropDown1.CalculatorElement.ShowPopup();
}
void CalculatorElement_PopupClosing(object sender, Telerik.WinControls.UI.RadPopupClosingEventArgs args)
{
    args.Cancel = true;
}

Let me know if you have additional questions.

Hi Dimitar,

I've done as you suggest, but I'm finding the calculator is 'floating' so when the form is moved, the calculator stays behind, as if it is not a control on the form.

I wish it to be anchored and sized to the width of the radform (fixedtoolwindow) so it moves as the form is dragged around the screen, and also matches the opacity of the form which can be adjusted.

Many thanks,

Martin.

Hello Martin,

Thank you for writing back.

You can move the drop down along with the form. For example you can change the drop-down location in the LocationChanged event:

void RadForm1_LocationChanged(object sender, EventArgs e)
{
    var newLoc = new Point(this.radCalculatorDropDown1.Location.X + this.Location.X + 4, this.radCalculatorDropDown1.Bounds.Bottom + this.Location.Y + this.FormElement.TitleBar.ControlBoundingRectangle.Height);
    this.radCalculatorDropDown1.CalculatorElement.Popup.Location = (newLoc);
}

Please let me know if there is something else I can help you with.
