I need to find a control that's contained in a Template column when I get into a RowDrop event. The control is in the DraggedItem object, and is always null. Any suggestions?

 Dim index As Integer = CInt(e.DraggedItems(0).ItemIndex)
 Dim oList As DropDownList = CType(RadGrid1.Items(index).FindControl("oList"), DropDownList)
 Dim s As String = oList.SelectedValue

Thanks,
Alex

RadTextBox script error: Script control 'myRadTextBox' is not a registered script control

I got this error when I create a Radtextbox control in my page.

Script control 'txtRechazoComentarios' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

My aspx goes like:

<telerik:RadMultiPage ID="rmpTabs" runat="server" SelectedIndex="0">

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

...

<telerik:RadAjaxPanel ID="rapAutorizaRechaza" runat="server">

<asp:Panel ID="PanelAutorizaRechaza" runat="server" Visible="false">

...

<telerik:RadTextBox ID="txtRechazoComentarios" runat="server" Visible="true" TextMode="MultiLine" Width="98%" Height="98%" >

<ClientEvents OnLoad="MostrarTxtRechazo" />

</telerik:RadTextBox>

...

</asp:Panel>

</telerik:RadAjaxPanel>

...

</telerik:RadPageView>

</telerik:RadMultiPage>

and the scripts:

function MostrarTxtRechazo() {

var rechazo = document.getElementById('hdnRechazar');

if (rechazo != null && rechazo.value == 1 && (TieneInnerHTML('<%= lblErrorMotivo.ClientID %>') || TieneInnerHTML('<%= lblErrorPassword.ClientID %>'))) {

MostrarElemento('lblRechazoComentarios');

MostrarElemento('divRechazoComentarios');

}

I already tried the RegisterWithScriptManager="false" property, but hen I got some weird error saying:
Microsoft JScript runtime error: Object doesn't support property or method '$'
at Telerik.Web.UI.WebResource.axd
var d=$telerik.$(a);

can you guide me through this?
thanks

RadNumericTextBox and French Culture

We use rad numeric text boxes in a web application that switches culture based on the user.
Everything works fine except the key under the 3 on the keypad is a point "." and the rad numeric textbox won't take it as the decimal separator (comma in French) when the culture if in French. I have been shown that in Excel it switches it to a comma. Everything else related to the other Rad Controls react exactly as expected in the French culture. Does anyone have any recommendations on how to deal with this?
Any suggestions would be greatly appreciated.
Thanks,
Jeff

Accessing the Bind value of Text='<%#Bind("firstname") %>'

In the code-behind I am attempting to see what the "bind" value is for Text='<%#Bind("firstname") %>'. The answer I am looking for in the example is "firstname".
I know there has to be a way of accessing that value so any ObjectDataSource or other binding method can be used for setting that value when the RadTextBox is displayed or updated.
You may ask why? I am attempting to create a generic way to pre-set values when inserting by using the Bind attribute/property's value.

I hope I made myself clear
Thanks
Kelly

Calculate Number of Days in Grid Column

The following represents the grid I am trying to construct:

DateReceived DateShipped Days
01/20/2011 NULL 30
04/01/2011 04/15/2011 15
04/10/2011 04/12/2011 3
01/15/2011 04/2/2011 2

Columns one and two are populating successfully from my SqlDataSource. No problem there. Column three is intended to be a calculated value that displays the number of active days for a given date range. For example, if the given start date was 4/1/2011 and the given end date was 4/30/2011, we would calculate 30, 15, 3 and 2 for the four rows in the grid. That's because the first data record row represents an item that was received in January and has not been returned. Therefore it was held for the entire 30 days of the month of April, 2011. The next rows are self-explanatory.

To capture the date range I have a RadComboBox for month and another for year.

To summarize, my question is how do I implement an expression for column three to calculate the correct number of days? I'm happy to do this server side or client side.

*Note: I'm using mm/dd/yyyy notation.
