How to get a border around each day in calendar?

Sounds simple, but, I'm trying to avoid the double border. Meaning, I can easily set the WeekendDayStyle.BorderWidth = 1, BorderColor=Black and BorderStyle = Solid, but, what happens is that all the days in the middle of the calendar control now have double borders because it's putting a border on the cell next to it also.

Is there a way to get a single border around each cell? So, in effect, it would need to know if a cell next to it already has a border?

LoadOnDemand from Webservice and multiselection

I have a RadComboBox that gets the data from a wcf-webservice.

In OnClientItemDataBound i change the text to be able to show multicolumn data and it works fine.
Now I wants to be able to select multiple items and I don´t know how to do that.

My idea is
I've tried to add a checkbox in OnClientItemDataBound and I get the checkbox in the dropdown.

var item = e.get_item()

item.set_text('<p class="rcbItemKey"><input type="checkbox">' + item.get_value() + '</p><p class="rcbItemData">'+ item.get_text() + '</p>');

In OnClientBlur I'm will loop through all the items in the dropdown and for each item check if the checkbox is selected. If it is checked I will add the value of the item to SelecteValue as a ;-separated list.

How do I find the checkbox in OnClientBlur?
Any other idea on how to solve it?
Another problem is that if I select 2 items in the dropdown and close the dropdown and the wants to open it again, the values should be selected. Is it possible to solve?

Performance problem on line chart

I'm wondering if there is something I can do to make the line chart go a lot faster. I have a couple thousand points I want to plot and use the code below. It takes almost 15 seconds to make the graph. When I cut the number of points to plot to 200, it takes less than a second. Here is the code I'm using

ChartSeries chartSeries = new ChartSeries("Altitude", ChartSeriesType.Line);

chartSeries.Appearance.ShowLabels =

false;

incrementCount = 1;

for (int i = 0; i < listData.Count; i = i + incrementCount)

{

chartSeries.AddItem(

new ChartSeriesItem(listData[i].x, listData[i].y));

}

RadChart2.AddChartSeries(chartSeries);

RadChart2.ChartTitle.TextBlock.Text = title;

RadChart2.PlotArea.XAxis.AxisLabel.TextBlock.Text =

"Distance (Miles)";

RadChart2.PlotArea.XAxis.AxisLabel.Visible =

true;

RadChart2.PlotArea.XAxis.IsZeroBased =

true;

RadChart2.PlotArea.YAxis.AxisLabel.TextBlock.Text = yAxisLabel;

RadChart2.PlotArea.YAxis.AxisLabel.Visible =

true;

RadChart2.PlotArea.YAxis.IsZeroBased =

false;

Security Problem ( Disable = "true" )

hi

That is an security problem "Enabled = false"

It is still possible to use Firebug, or another tool, to tamper with the submitted value, and to remove the "disabled" HTML attribute to change the value. Any suggestion to solve this? This can be easly be hack the data by changing the value.

RadToolTipManager + asp:UpdatePanel = “Cannot unregister UpdatePanel with ID 'RadToolTipManager1RTMPanel'…”

Here is my situation, I have a UserControl that has a simple Image, Label and a RadToolTipManager that gets the tooltip info via a WebService for both the Image and the Label. This UserControl is used on a RadGrid that goes inside an asp:UpdatePanel on a page Default.aspx. Inside the UpdatePanel I also have a RadTreeView that updates the content of the Grid on the onNodeClick event and the Default.aspx implements a MasterPage that has the asp:ScriptManager.

Great, so the on the Load of the Default.aspx page I load the TreeView and force the onNodeClick of the RootNode so the Grid is populated too. Until this point all works fine, the control displays the information fine and the RadToolTipManager shows the tooltip info from the WebService also fine.

The problem comes when I click on a different Node from the TreeView to and I reload the Grid contents causing the error:

“Cannot unregister UpdatePanel with ID 'RadToolTipManager1RTMPanel' since it was not registered with the ScriptManager. This might occur if the UpdatePanel was removed from the control tree and later added again, which is not supported.

Parameter name: updatePanel”

This error occur on the Grid.DataBind() line on the Default.aspx page.

I have a simple solution that replicates the problem but can't upload the files here, so will put some snippets below...

I already tried to use ScriptManagerProxy on both the Default.apsx and the Control.ascx, also tried to use the RadAjaxPanel instead of the UpdatePanel or using RadAjaxManager and RadAjaxManagerProxy and follow both (the only ones I could find) treads Compatibility with .NET 3.5 UpdatePanel? and RadAjaxManager initialized too late in the page life cycle but nothing changed.

My last try was to Register the RadToolTipManager programmatically on the control by getting the ScriptManager Instance but if I do that I get the error on the first page load instead.

Well, I am quite stuck with this situation now, and because of business requirements the ToolTip on this particular page is really important for the App. Anyone has any ideas on how to fix this?

Fromdecorator not styling labels within Masterpage

I setup a basic masterpage and added a RadFormDecorator with decoratedcontrols="all". I then create a new webform from the masterpage and run the web project but labels are not styled. Other web controls are styled.

What am I missing? here is the simple master page:

You can notice the label within (<div id="header"> ) is not styled.

Upload button cut off in IE8, IE9 Comp on

We have a rad upload control which shows the full upload message in IE9 - see the attachment fullbutton.jpg.

When in IE8, or IE9 with comp on, the button looks like what's in attachment halfbutton.jpg. There is no upload text, and all you can see is the paper clip.

I've tried setting EnableFileInputSkinning to both true and false, plus tried css class settings for rubrowse and rubutton and such that I've found on the web, all to no avail.

The upload control is being used in a user control, and is part of the content of a radwindow. Here is a code sample - I didn't include the whole page.

<telerik:RadWindowManager ID="RadWindowManager1" runat="server" Overlay="true">

<Windows>

<telerik:RadWindow ID="RadWindow1" runat="server" Animation="Fade" Behavior="None" VisibleOnPageLoad="false"

Behaviors="Close" Modal="true"

Width="490" Height="565" DestroyOnClose="true" VisibleStatusbar="false" KeepInScreenBounds="true" >

<ContentTemplate>

...

<script type="text/javascript">

try {

Telerik.Web.UI.RadAsyncUpload.Modules.Silverlight.isAvailable = function () { return false; }

} catch (e) { }

</script>

<telerik:RadAsyncUpload ID="fuDocument" runat="server" MaxFileInputsCount="1"

ReadOnlyFileInputs="true" OnClientFileUploaded="triggerRefresh" OnClientFileUploadRemoving="triggerCancel" MaxFileSize="4194304"

OnClientFileSelected="triggerSelected" OnClientValidationFailed="fileValidationFailed" Localization-Select="">

</telerik:RadAsyncUpload>

...

</ContentTemplate>

</telerik:RadWindow>

Can you tell me what could be causing this?
