Inherit from RadPanelBarEventArgs

I'm trying to add some extended properties to a RadPanelItem like so:

Public Class RadPanelItemExtended

Inherits Telerik.Web.UI.RadPanelItem

Private _HasChildren As Boolean

Public Property HasChildren() As Boolean

Get

Return _HasChildren

End Get

Set(ByVal value As Boolean)

_HasChildren = value

End Set

End Property

End Class

To access the extended properties on RadPanelBar.ItemClick i need to make the RadPanelBarEventArgs handle RadPanelItemExtended class rather than RadPanelItem class. I thought this was possible through creating an extended eventargs class like so:

Public Class RadPanelBarEventArgsExtended

Inherits Telerik.Web.UI.RadPanelBarEventArgs

Private _RadPanelItemExtended As RadPanelItemExtended

Public Property RadPanelItemExtended() As RadPanelItemExtended

Get

Return _RadPanelItemExtended

End Get

Set(ByVal value As RadPanelItemExtended)

_RadPanelItemExtended = value

End Set

End Property

Sub New(ByVal item As RadPanelItemExtended)

MyBase.New(item)

Me._RadPanelItemExtended = item

End Sub

When using these extended classes like this:

Protected Sub RadPanelBar_ItemClick(ByVal sender As Object, ByVal e As RadPanelBarEventArgsExtended) Handles RadPanelBar.ItemClick

End Sub

I get the following error:
Unable to cast object of type 'Telerik.Web.UI.RadPanelBarEventArgs' to type 'RadPanelBarEventArgsExtended'.

Why is this?

Regards
Richard

Disabling Toolbar items

When you disable a regular toolbar button it's greyed out.

This isn't true for SplitButtons (and, I assume, DropDownButtons).

My user base find this confusing as the button looks like it can be clicked when it can't. Is there a way of changing this behaviour so that it acts more like regular buttons?

Problems when upload File in Usercontrol

Hello everybody,

Please help me :(
I build a page with TabStrip, TabStrip has MultiPages, each page is added user control(The control is add inside code in file .cs of page with function RadMultiPage1_PageViewCreated).
In one TabPage, I import a Radupload RadUpload1 to upload files to server, and a Button btnUpload for submitting Upload File. After selecting File, clicking Button, the first thing which is done is function RadMultiPage1_PageViewCreated called again to reload all usercontrol, and then the function btnUpload_Click is called. But now, the RadUpload1 is reset, so, RadUpload1.UploadedFiles is null, all Files which I selected before are not catched in my code, not to uploaded to server.

Please give me some solutions for this problem, men.

Thanks very much for your help.

Where to set AllowedFileExtensions property for RadUpload in RadGrid

Hi,

I have a RadUpload in a RadGrid. I would like set the AllowedFileExtensions property at the code-behind rather through the aspx page itself. In which event should I set this? I've tried it in the '... Insert' event, but it seems that the code does not detect it and allowed the invalid files to go through.

Thanks,
Bernard

SelectedValue from dropdownlist via OnCommand

I'm trying to get the selected value from a dropdownlist in a radgrid from GridTemplate when being called from a command button.
I don't know how to get the value to pass to an update procedure. ddlassessPeriod.SelectedValue doesn't work when its in ItemTemplate.
Here's some sample code:

<telerik:RadGrid ID="RadGrid1" runat="server" >

<MasterTableView>

<Columns>

<telerik:GridTemplateColumn UniqueName="TemplateColumn>

<ItemTemplate>

<asp:DropDownList ID="ddlassessPeriod" runat="server"

SelectedValue='<%# Eval("assessPeriod") %>'>

<asp:ListItem Value="0" Text="N/A" />

<asp:ListItem Value="1" Text="1" />

<asp:ListItem Value="2" Text="2" />

</asp:DropDownList>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridTemplateColumn UniqueName="TemplateColumn" AllowFiltering="False">

<ItemTemplate>

<asp:Button ID="update" runat="server" Text="Update"

OnCommand="update_Command" CommandName='<%#Eval("seid")%>' />

</ItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

protected void update_Command(object sender, CommandEventArgs e)

{

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["curriculum"] + "");

conn.Open();

class.update(conn, ddlassessPeriod.SelctedValue, Convert.ToInt32(e.CommandName));

}

radgrid itemdatabound on records on first page

I have a question about how itemdatabound works. I have a sql query that pulls about on average 200 records, not a lot, query runs in seconds. My problem is i have validation on every column, about 15 columns in each row, that needs to happen but i think that itemdatabound runs against all the data pulled from the SQL query instead of the first 20 records in the radgrid. i have the radgrid paging set to 20 records per page. is there a way to have itemdatabound events to run only on the page being viewed instead of all records returned???
