get a control in an itemtemplate with javascript

Hi,
There tons of sample for "get a control in an itemtemplate with javascript". But I have a problem.

I have a grid like below. When cbAllCanSelect is checked, I try to find all checkboxes in a column and check them all.

<telerik:RadGrid ID="rgOptions" runat="server" AutoGenerateColumns="False"

ResolvedRenderMode="Classic" AllowMultiRowEdit="True">

<MasterTableView>

<Columns>

<telerik:GridBoundColumn DataField="KARAKTERTANIM"

FilterControlAltText="Filter column column" HeaderText="Option"

UniqueName="column">

</telerik:GridBoundColumn>

<telerik:GridTemplateColumn FilterControlAltText=""

HeaderText="Selection" UniqueName="TemplateColumn">

<ItemTemplate>

<asp:HiddenField ID="hfKarakter" runat="server" Value = '<%# Eval("KARAKTER") %>'/>

<asp:CheckBox ID="cbCanSelect" runat="server" Checked = '<%#bool.Parse( Eval("CANSELECT").ToString()) %>'/>

</ItemTemplate>

<HeaderTemplate>

<telerik:RadButton ID="cbAllCanSelect" runat="server" ToggleType="CustomToggle" ButtonType="ToggleButton"

AutoPostBack="false" onclienttogglestatechanged="toggleCanSelectCheckBoxes">

<ToggleStates>

<telerik:RadButtonToggleState Text="" PrimaryIconCssClass="rbToggleCheckbox">

</telerik:RadButtonToggleState>

<telerik:RadButtonToggleState Text="" PrimaryIconCssClass="rbToggleCheckboxFilled">

</telerik:RadButtonToggleState>

<telerik:RadButtonToggleState Text="" PrimaryIconCssClass="rbToggleCheckboxChecked">

</telerik:RadButtonToggleState>

</ToggleStates>

</telerik:RadButton>

</HeaderTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

My script (ignore button toogle and just check them all):

function toggleCanSelectCheckBoxes(sender, args) {

//alert(sender.get_selectedToggleState().get_index());

var dataItems = $find('<%=rgOptions.ClientID%>').get_masterTableView().get_dataItems();

for (var i = 0; i < dataItems.length; i++) {

var cb = dataItems[i].findControl("cbCanSelect");

alert(cb);

if (cb != null)

cb.checked = true;

}

I cant find "cbCanSelect". "cb" is always return null.

What is my mistake?

Thanks a lot.

Columns get disappeared after resizetofit()

Hello,

I have three radgirds in RadTabStrip (1 grid in 1 tab), I want to achive the resize to fit facility. so I have written following code with "AllowColumnResize='True' AllowRowResize='false' ResizeGridOnColumnResize='true' AllowResizeToFit='true'" property settings of grid.

var grdstQ = $find("<%= Grid1.ClientID %>");
                    var clmstQ = grdstQ.get_masterTableView().get_columns();
                    for (var i = 0; i < clmstQ.length; i++) {
                        clmstQ[i].resizeToFit(false, true);
                    }

I have applied the above code solution for all three grids, the first grid in tab working fine but columns in other two grids disappeared after apply the same solution.

Please suggest, I am not getting how to resolve this strange issue.

Thanks in advance.

Regards,
Vishal

Event ending after midnight

I am using the RadScheduler for a website that will display bar events. Many of these events will end after midnight. I am trying to avoid having such events appear across 2 days on the calendar when in Month or Week view. Is there a way to do this? Can the Scheduler be configured so that days start at 6:00AM and end at 5:59AM?

Thanks for any help.

Series Labels Overlap on Bubble Chart

I am trying to create a Bubble chart but when bubbles occupy the same space the series labels are rendered on top of each other.

Is there anyway to keep this from happening. Maybe add some sort of offset?

Vertical scroll ruins layout of rowheader

LS,

After changing the value of the property 'ClientSettings-Scrolling-AllowVerticalScroll" to "true" the layout of the grid changes in an undesired way.
(Check the images).

The width of the second header column cannot hold the text anymore. The second header column seems to be rendered with the width of the first (85px) and vice versa (300px).

I'm fairly new to this control and have no idea why such a simple change has such an impact. I must be doing something else wrong but i cannot find anything strange in the code (provided below).

Anyone any idea why the grid behaves like this?

<telerik:RadPivotGrid ID="pivControles" runat="server"
