Chrome, ColumnHeaderDateFormat and swedish culture.

Hi,

I have noticed that the RadScheduler fails to render all the dates in the column header in Chrome using timelineview mode. I have only tried with swedish culture standards.

It can be achieved by either:
1. Setting the TimelineView-ColumnHeaderDateFormat to "yyyy-MM-dd".
2. Settings the RadSchedulers Culture to sv-SE.

It works perfectly using american culture or date format.

Is this a known bug or is there any workaround?

Best regards,
Daniel

async databinding

Hello,

I'm trying to make use of the NeedDataSource event in order to bind the grid to a datasource that may cause a page timeout. The data collection process is pretty hefty, and I need to be able to load everything on the page without having to wait for the grid to collect its data. The html looks like this:

<

telerik:RadAjaxLoadingPanel ID="RadAjaxLoadingPanel1" runat="server" >

<

asp:Image id="imgLoading" runat="server" ></asp:Image>

</

telerik:RadAjaxLoadingPanel>

<

telerik:RadAjaxPanel ID="RadAjaxPanel1" runat="server" LoadingPanelID="RadAjaxLoadingPanel1">

<

telerik:RadGrid ID="CWGrid" runat="server" Width="100%" OnNeedDataSource="CWGrid_NeedDataSource" >

</

telerik:RadGrid>

</

telerik:RadAjaxPanel>

And in the Need Data Source:

public

void CWGrid_NeedDataSource(object source, GridNeedDataSourceEventArgs e)

{

DataSet objSD = SetData();

if (objDS.Tables.Count > 0)

CWGrid.DataSource = objDS;

}

SetData() is where the data collection occurs, and sometimes causes a page timeout. Please let me know what I'm missing.

Do I have to Set PageViewID?

Hello,

If I have a radtabstrip attached to a radmultipage by setting multipageid, by default does the tabs attach to the page view at the same index, or do I have to explicitly set PageViewID?

If not defaulting by index, I would like to submit that as a control enhancement, that the pageview at index 0 be automatically linked to the tab at index 0, and so on.

Thanks.

RadRotator with ButtonsOver

Hello,

I used a RadRotator for a images gallery, with the "RotatorType=ButtonsOver", but after a few itens the images start to go off the area.
In the demos could also replicate the problem (attach the capture to check the issue).
Is there any solution or work around to solve this?

Thanks,
Joaquim Oliveira

RadAjax? not allowing JScript to Access current value of ViewState Server Variable

Hi All,

I need to access the current value of a Server Side variable (stored as a ViewState var) from a Java Script.
easy enough...eg

var i == <%= OGridItem_ItemIndex %>

but, If I set the value in Server code, and on Client Side try to Access it, I get it's previous (initial value) , not it's new current value??
I have RadAjax Manager and grid on page and all ajaxified ControlId's and UpdatedControls in it. And that Server set Viewstate Var is not nor seems to be able to be.
Script and Grid are wrapped in RadCodeBlocks.

If I try it a few times, it always returns the Previous not current value.
The current Value is set in C# after a straightforward __DoPOstback(Arg_Source, EventArgs). The rest of the Controls on the page are set for Ajax postbacks as per the RadAjaxManager.

How do I retrieve the current value of this ViewState Var when in JS??

Thx
Neal

Trouble unchecking treenodes with node enable/disable

My requirement is that if a parent node is checked, all the children must be checked. We like the tristate checkbox functionality. So, what we'd like is when the parent is checked, the childnodes are disabled so that they may not be unchecked. This causes a problem with expanding and collapsing, but I've seen that there is a workaround for that. My problem comes with unchecking the parent. It unchecks and then comes right back again. There is also a problem with enabling nodes again once disabled, i.e. if the node is being unchecked due to CheckChildNodes property, the NodeCheck event is not fired and it never gets enabled again.

<telerik:RadTreeView ID="rtvVendor" runat="server" CheckBoxes="True"CheckChildNodes="True"

Skin="Outlook" TriStateCheckBoxes="true" Width="500px"Height="400px" BorderStyle="Solid"
