}

As you can see, there is two buttons which control the volume (VolumeUpButton and VolumeDownButton ), But I need to control the volum using the RadSlider.

Attached with this post a screen shot of the page.
Please, can you explain to me why the mp3 file is being restarted every time I try to control the volume using the radsilder control.
It is apprecited to send me the modified code which solves the above code.

Regards,
Bader

[Solved] Listbox Loading Listbox

I'm trying to get information from one list box to populate another list box. I'm doing a drag and drop from a list box called available to a list box called selected. After this has been done I would like to populate another list box called selected2 based on what was in the list box called selected. I'm able of course to get the drap and drop to work but how do you get the id's from the selected list box.

Thanks,
Mike

Plotted Points on Point series appear cropped

Hi,

The points on a plotted point chart series appear to be cropped in to half circles. They are plotted exactly on the start axis and end axis edges(see attachment). I would like to see them plotted within the borders, hopefully able to set the padding or margins, whatever needed. X-Axis layout mode is Normal, Y-axis AxisMode is Extended. X-axis value format is shortdate. Please direct me rightly.

Thanks.

bug: cannot enable item when disabled declaratively

2010.2.809.35 VS2008 IE8

I have an item that is declarative set to enabled false that cannot be re-enabled with item.enable. It stays disabled.
If it was NOT declarative disabled then I can disable then enable using the client API.

<telerik:RadListBoxItem Enabled="false" Text="Apple" Value="Apple" />

var items = listbox.get_items(); items.forEach(function(item) { item.enable(); item.check(); });

Update: If the item is set to disabled in code, it could not be enabled in Javascript.

y axis fractional values

On the y axis of my bar chart I have Number of Households. Obviously, this number is always an integer but I am sometimes getting the following on the y axis: 0, 0.5, 1, 1.5, 2, 2.5, etc.

The plot is coming out correctly. The x axis shows dates and the plot is usage by y-number of households on a given date.

How can I force the y axis to show only integers?

Thanks.

RadNumericTextBox - Enter

I'd like that when the user press "Enter" on my RadNumericTextBox it would be the same as if he would give a click on a especific button.
The definition of my RadNumericTextBox is:

<telerik:RadNumericTextBox ID="radMyNumericTextBox" runat="server" Width="132px">
<ClientEvents OnKeyPress="radMyNumericTextBox_KeyDown" />
</telerik:RadNumericTextBox>
My code is:
private void radMyNumericTextBox_KeyDown(object sender, KeyEventArgs e)

{

if (e.KeyCode == Keys.Enter)

{

btnMyButton_Click(sender, e);

}
}
Note: Actually if I press "Enter" in the RadNumericTextBox close's my window.
Any help?
Thank you very much.
