Paging: Group Aggregate For All Data Rows

I have a RadGrid configured with Paging and Grouping with Aggregates
- AllowPaging = true
- ShowGroupFooter = true
- RetainGroupFootersVisibility=true

<telerik:GridGroupByExpression>

<GroupByFields>

<telerik:GridGroupByField FieldName="A" SortOrder="Ascending" HeaderText="A" />

</GroupByFields>

</telerik:GridGroupByExpression>

I have 1 column defined as Aggregate

<telerik:GridBoundColumn AllowFiltering="False" SortExpression="Amount"

DataField="Amount" DataFormatString="{0:C2}" Groupable="False" HeaderText="Amount"

ReadOnly="True" Reorderable="False" Resizable="False" UniqueName="Amount"

Aggregate="Sum">

</telerik:GridBoundColumn>

Problem

The RadGrid, by default, appears to Aggregate for items in the current page (i.e. The Grouping Total that appears in the GroupFooter... only applies to visible items on the currently selected page (even when the group extends into other pages).

Question

How can I implement a custom aggregate in which I sum all of the values for a particular column within a group (across all data items that are in the group / i.e. across all pages)?

Captions when exporting in BIFF Format

In any other excel format, the caption appears as an extra row at the top of the spreadsheet. Is there a way to get this behavior when exporting to BIFF?
If not is there a way to insert an arbitrary row at the top of the resultant spreadsheet?

Thanks!

Page.IsValid incorrect when RenderSelectedPageOnly=true in RadMultiPage

Hi,

I have a RadTabStrip tied to a RadMultiPage. The RadTabStrip has CausesValidation="false" and the ontabclick event is handled. In the event handler, I call Page.Validate() and then inspect Page.IsValid. When the RadMultiPage control has RenderSelectedPageOnly="false", this works as expected. When it has RenderSelectedPageOnly="true", my validator is effectively ignored and Page.IsValid is returned as true.

Example code:

<telerik:RadScriptManager ID="rsm" runat="server"></telerik:RadScriptManager>

<telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">

<AjaxSettings>

<telerik:AjaxSetting AjaxControlID="RadTabStrip1">

<UpdatedControls>

<telerik:AjaxUpdatedControl ControlID="RadTabStrip1" />

<telerik:AjaxUpdatedControl ControlID="RadMultiPage1" />

<telerik:AjaxUpdatedControl ControlID="ltResult" />

</UpdatedControls>

</telerik:AjaxSetting>

</AjaxSettings>

</telerik:RadAjaxManager>

Result: <asp:Literal ID="ltResult" runat="server" Text=""></asp:Literal>

<br />

<telerik:RadTabStrip ID="RadTabStrip1" runat="server" MultiPageID="RadMultiPage1"

ontabclick="RadTabStrip1_TabClick" SelectedIndex="0" CausesValidation="false">

<Tabs>

<telerik:RadTab runat="server" Text="Root RadTab1" PageViewID="RadPageView1" Selected="True">

</telerik:RadTab>

<telerik:RadTab runat="server" Text="Root RadTab2" PageViewID="RadPageView2">

</telerik:RadTab>

</Tabs>

</telerik:RadTabStrip>

</div>

<telerik:RadMultiPage ID="RadMultiPage1" Runat="server" SelectedIndex="0" RenderSelectedPageOnly="false">

<telerik:RadPageView ID="RadPageView1" runat="server">

Tab 1 content: <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>

<asp:RequiredFieldValidator ID="rfv_TextBox2" runat="server" ControlToValidate="TextBox2" ErrorMessage="Client Error">

</asp:RequiredFieldValidator>

</telerik:RadPageView>

<telerik:RadPageView ID="RadPageView2" runat="server">

Tab 2 content:

</telerik:RadPageView>

</telerik:RadMultiPage>

protected void RadTabStrip1_TabClick(object sender, Telerik.Web.UI.RadTabStripEventArgs e)

{

Page.Validate();

if (Page.IsValid)

{

ltResult.Text = "page is valid";

}

else

{

ltResult.Text = "page is not valid";

}

If you run this code and click on the second tab, the ltResult control shows "page is not valid". This is correct as there is a requiredfieldvalidator in the RadPageView. If you change the value of RenderSelectedPageOnly to "true", the ltResult control shows "page is valid", which is incorrect.

In reality, my page has several RadPageView controls with dynamically loaded usercontrols containing a lot of content. I need to be able to set RenderSelectedPageOnly="true" to save on bandwidth and client processing time. Can you tell me how to get this working with RenderSelectedPageOnly="true"?

I am using Version 2010.3.1215.40 of Telerik RadControls for ASP.NET Ajax.

Thanks,

Craig

RadSpell not working in IE9

Hello,

It seems that the component does not work in IE9, based on clicking around on the RadSpell demos on the site. After a few clicks, the popup window shows up, but is blank.

I have also had the issue on a simple web application when debugging in Visual Studio. Seems an exception is thrown when trying to create an iframe element (if in IE). I have attached the screenshot from VS.

Thanks,

-Chris

change/add descripttion when update an appointment

I trying to add a description "Override" when update an appointment.

I'm using e.ModifiedAppointment.Description = "Override", but it doesn't work.
Here is my scripts:

Protected Sub MyAvailability1_AppointmentUpdate(sender As Object, e As AppointmentUpdateEventArgs) Handles RadScheduler1.AppointmentUpdate
        Dim scheduler As RadScheduler = DirectCast(sender, RadScheduler)
        If e.ModifiedAppointment.Subject = "Preference" Then
            For Each app As Appointment In scheduler.Appointments.GetAppointmentsInRange(e.ModifiedAppointment.Start, e.ModifiedAppointment.[End])

                If app.Subject = "Availability" Then
                    If app.Start > e.ModifiedAppointment.Start OrElse app.[End] < e.ModifiedAppointment.[End] Then
                        e.Cancel = True
                    End If
                End If

Next
End If

If e.ModifiedAppointment.Subject = "Availability" Then
For Each app As Appointment In scheduler.Appointments.GetAppointmentsInRange(e.ModifiedAppointment.Start, e.ModifiedAppointment.[End])

                If app.Subject = "Preference" Then
                    If app.Start < e.ModifiedAppointment.Start OrElse app.[End] > e.ModifiedAppointment.[End] Then
                        e.Cancel = True
                    End If
                End If
            Next
        End If
        e.ModifiedAppointment.Description = "Override"
    End Sub

Support for RadControl Q12007

Hi

I am using RadControls Q1 2007 for my web application development, I would like to know whether the Drag and Drop functionality is available with Q1 2007 Controls?

Somehow I am not getting client side events like "OnClientNodeDragging" and boolean properties like "EnableDragAndDrop", is there any way to archive this? or any other alternative?

Is is really possible to do Drag and Drop functionality in Q1 2007 Controls?

Thanks,

Rahul

RadNumericTextBox Format

Hi,

I'm having problem with the format in the textbox.
Today it looks like:

<telerik:RadNumerictextBox ID="txtValor" runat="server" MinValue="0">

<NumberFormat AllowRounding="true" DecimalDigits="2">

</telerik:RadNumerictextBox>

When I fill with the value "50,45" for example, text and value properties are as follows:
Text: 50,45
Value: 50.450000000000003
I do not understand, if I defined only two decimal places, why the 14 digits? this is a bug?
