Error: Could not find a part of the path...

I have developped some aspx page with a RadUpload Control.
After setting everything on my dev server, it worked fine
but when uploading it on the prod server, I received the following message after clicking the "Submit" button;

    
            Server Error in Application.     
        
            Could not find a part of the path 'F:\Applications\Upload\Hours\test.txt'.     
        
            Exception Details: System.IO.DirectoryNotFoundException: ...

My question is; what are the access right requirements for RadUpload to work?
As in an intranet environment, we setted up a generic account for this IIS application with Full rights on this folder but I suspect maybe something with the rights, any hint?

Regards,
David

RadUpload and RadProgress last file does not appear to finish.

Ok,

Been playing with Telerik for a little while, really like it, thinking about purchase but I hit a wall.

I have a content page that has NO update panels just the rad controls and a couple of datalists to display the results...works on my machine and on the server but on the server when we upload a large amount of files it uploads just fine BUT the progress control never finishes on the users screen but the upload does work...I cannot replicate on my dev machine so i cant figure the problem...The control works perfectly on two or three files and its not specific on how many files it takes to fail...

Does this set of controls have issues on GoDaddy?

Code Below,

Thanks!

problem with upload

hi,

I have a radUpload control named "radUp".

When I click on the submit button I call "uploadFile" :
"renameFile" is the new name written by the user on a textbox.
I want to save the file with this name, but I have 2 files on my Directory "Documents" after click: the renamed file and the other .... I want only the renamed file ... what's wrong?

protected void uploadFile()

{

if (radUp.UploadedFiles.Count > 0)

{

foreach (UploadedFile file in radUp.UploadedFiles)

{

String targetFolder = Server.MapPath("~/Documents");

file.SaveAs(Path.Combine(targetFolder, renameFile.Text));

}

Thanks

Close radwindow when button click inside a formview

I have a formview inside my radwindow. If close button is clicked inside a formview I want the window to close.
I tried to call javascript to close window, event is fired, but it does not close the window.
********** Javascript ************

function GetRadWindow() {
                var oWindow = null;
                if (window.radWindow)

Rad Datepicker and DateTime Problem

Hello,

When I try to use raddatepicker.selecteddate for a datetime var I get this error:

Cannot implicitly convert type 'object' to 'System.DateTime'. An explicit conversion exists (are you missing a cast?)

Here is my code:

public partial class RegistroFalla
{
public int ID_Falla { get; set; }
public Nullable<int> Duracion_Falla { get; set; }
public System.DateTime Fecha { get; set; }
public System.DateTime Hora_Deteccion { get; set; }
public System.DateTime Hora_Diagnostico { get; set; }
public System.DateTime Hora_Ocurrencia { get; set; }
public System.DateTime Hora_Recuperacion { get; set; }
public System.DateTime Hora_Solucion { get; set; }
public string Descripcion { get; set; }
public System.DateTime Tiempo_Deteccion { get; set; }
public System.DateTime Tiempo_Recuperacion { get; set; }
public System.DateTime Tiempo_Reparacion { get; set; }
public System.DateTime Tiempo_Respuesta { get; set; }
public string Division { get; set; }
}

var Fallo = new RegistroFallas.Model.RegistroFalla
{
Hora_Ocurrencia = dpOcurrencia.SelectedDate,
Fecha = rdpFecha.SelectedDate,
Descripcion = txtDescripcion.Text,
Hora_Deteccion = rdpDeteccion.SelectedDate,
Hora_Diagnostico = rdpDiagnostico.SelectedDate,
Hora_Solucion = rdpSolucion.SelectedDate,
Hora_Recuperacion = rdpRecuperacion.SelectedDate
};

Thanks,

Jorge

Combining GroupByExpressions and Paging

The code that I'm managing used an older version of the Telerik assemblies. We recently upgraded the assemblies to the most recent version. Upon upgrading said files, I received complaints that the paging was no longer showing on a grid. This is weird, since "Allow Paging" is set to True in the markup. I did some playing around and noticed if I removed the GroupByExpressions from the grid, the paging works fine. The GroupByExpressions seems to work fine either way, but is preventing the paging from working. Could someone possibly shine some light on the situation? I've included the grid's code below. Note: Ignore the empty strings; I removed some of the values for security reasons.

<telerik:RadGrid ID="RgStatusGrid" runat="server" AllowPaging="True" GridLines="None"

AllowSorting="true" PageSize="50" OnNeedDataSource="RgStatusGrid_NeedDataSource"

OnItemDataBound="OnItemDataBound" OnSortCommand="RgStatusGrid_SortCommand">

<MasterTableView AutoGenerateColumns="false">

<GroupByExpressions>

<telerik:GridGroupByExpression>

<SelectRegions>

<telerik:GridGroupByRegion RegionName="CityName" HeaderText="City" SortOrder="Ascending" />

</SelectRegions>

<GroupByRegions>

<telerik:GridGroupByRegion RegionName="StateName" HeaderText="State" SortOrder="Ascending" />

<telerik:GridGroupByRegion RegionName="CityName" HeaderText="City" SortOrder="Ascending" />

Session Timeout based on Inactivity

I was able to accomplish session expiration using the notification control set up for my web application thanks to this demo:

http://demos.telerik.com/aspnet-ajax/notification/examples/sessiontimeout/sessionexpired.aspx

However, this approach is based on a set timeout value and the notification just pops up every timed interval, regardless if the user is active or not. Can the session timeout be set/reset dynamically based on user inactivity? Possibly every time there is an Ajax request call? Some sample codes would be much appreciated. Thanks.

RadAjaxLoadingPanel updates but CascadingDropDown events do not fire

Greetings,

I am new to Telerik (pretty new to asp.net) and cannot figure out why my AXAX CascadingDropDown events do not fire when I wire them up to control my RadAjaxLoadingPanel. The LoadingPanel updates but no SelectedIndexChanged event is call.

My code works when I disable/remove theRadAjaxLoadingPanel

I looked all over for the CascadingDropDown example but no success. I saw that I might need to rebind, but I'm not sure what I'm looking for to do this? Thanks
