Persistence framework and ComboBox with checkboxes

I am not able to get persistence using a combobox with attribute Checkboxes="true". Works fine with Checkboxes="false".

Is multiple selections (checked items) handled by the persistence framework for the combobox control?

Inconsistent Button behavior

RibbonBarMenuItems when clicked append the # to the end of the url in the browser, this is true for Split buttons as well.

Normal RibbonBarButtons when clicked do not modify the url.

How can I prevent all button types from modifying the url. the appended hashtag is causing an issue with scrolling after partial postbacks.

I tried using the OnClientMenuItemClicking method and doing args.set_cancel(true); but this did not fix it.

Thanks.

The issue can be seen in the First Look demo as well. Scroll down the page and click Copy, does not scroll back to top. Next try a Paste option and the browser is scrolled back to top.

rad grid filtering is not working on tab key press first time

I have a radgrid and have enabled filtering. I have restricted the filtering to "startswith" only. The problem is that when I enter in some filter text it fires the ItemCommand event which is fine but, it does not filter the grid. If I re-type the filter string again it fires the ItemCommand event again and the second time and any more subsequent attempts work as expected resulting in the grid being filtered. This is so wierd and I have no idea whi I have to type in a filter string twice to get it to work.

X Axis Rotate Angle isn't normal

If you set the rotation angle in the X Axis, the text will render, apparently rotated around the center of the text.

<XAxis DataLabelsField="IncidentType">

<LabelsAppearance DataFormatString="{0}" RotationAngle="60">

</LabelsAppearance>

<TitleAppearance Text="Incident Type"></TitleAppearance>

</XAxis>

I've used a lot of different chart controls in Windows and web development, and this is the first time I've seen this. Normally, the label text on the x axis would be rotated with the pivot point being the first letter. That way, the beginning of the text is still centered underneath the column it goes with. Now the text looks like it is off, and you have to widen your chart to see that the pivot point of the rotation is the center of the text, not the left edge.
Can this get fixed? Or at least give us the option for how we want to rotate the text.

Thanks

Dyamic Footer Total Error

Hi,

We are using latest Radgrid in our asp.net application. I need to provide user a textbox to enter amounts into for each account. I need to show total amount entered by user for all accounts in footer. For this I am using template column with RadNumeric textbox like this:

<

telerik:GridTemplateColumn AllowFiltering="False" FilterControlAltText="Filter Amount column" Groupable="False" HeaderText="Amount" Reorderable="False" ShowFilterIcon="False" UniqueName="Amount" HeaderTooltip="Amount">

<telerik:RadNumericTextBox ID="txtAmount" runat="server"

Type="Currency" Width="75%" CssClass="rightalign">

</telerik:RadNumericTextBox>

</ItemTemplate>

<asp:Literal ID="Literal1" runat="server" Text="Sum"></asp:Literal>

<telerik:RadNumericTextBox ID="txtAmountTotal" runat="server" Type="Currency">

</telerik:RadNumericTextBox>

</FooterTemplate>

</telerik:GridTemplateColumn>

As suggested in the link:
http://www.telerik.com/community/code-library/aspnet-ajax/general/refresh-footer-values-in-radgrid-client-side-using-radnumerictextbox.aspx

I have code in java script.
When I run my app and enter into textbox,

function

Focus(sender, args)

{

tempValue = sumInput.GetValue() - sender.GetValue();

}

gets called and I get an error on this line saying that 'Object doesn't support property or method 'GetValue''. I am not sure where it is going wrong.

I am not using 'NeedDataSourceEvent' because my application is complicated and we bind the grid when ever it is required.

Thanks,
Prathiba
