Get current selected row on postback

Hi, when I edit my record I have the radupload component, however when it does the postback I want to get the current value of the selected grid row as this contains the id to be used for the file name. Could you assist on how I can get this information sent back as I found the the RadAsyncUpload1_FileUploaded gets called before the command method. thanks P

Emulate Google Images search results pagination w/ ListView and RadDataPager

Hi,

I am currently working on a Media Library module for a CMS. Reading a folder in the file system I bind the results to a RadListView that has a PageSize of n (12 at the moment) in order to display its content: images.

DirectoryInfo di = new DirectoryInfo(MediaLibPath);

FileSystemInfo[] files = di.GetFiles();

var fileByUploadedDate = files.OrderByDescending(f => f.CreationTime);

ResourceLV.DataSource = files;

ResourceLV.DataBind();

In the RadDataPager I have a RadButton with the OnClick

ResourceLV.PageSize += 12;

ReloadResourceListView();



ReloadResourceListView() rebinds the ListView. Very similar to this sample:



http://demos.telerik.com/aspnet-ajax/grid/examples/programming/customizingpager/defaultcs.aspx 





What I am trying to avoid is rebind every time as there could be hundreds of images in the folder being 

read. Is it possible to have the PageSize increase sort of like google images search results. 

What would your suggestion be? What about the PageSize from Grid, could that be emulated too?



Thanks

Filtering by multiple columns at once

I have a Grid with AllowFilteringByColumn set to true. Each column in the grid has the filer textbox plus the drop down list of search options. The CurrentFilterFunction is set to 'Contains' and Autopostback is set to true. So users can enter a value and press enter which will do a 'contains' search on that column.
However there are two things that users keep trying to do that cause odd behaviour.
- They will enter a filter value in the FirstName column, then enter a value in the LastName column and press enter. Since enter is pressed while focus is on the LastName column, only that column is filtered and the FirstName filter disappears.
- The second scenario is that they will do a filter on FirstName and press enter, then after viewing the results will delete the filter on FirstName and then type a filter into LastName and press enter. When you do this the lastName filter is applied but the FirstName filter isn't checked so it reappears.
Is there a way to do multiple filters at once? I'm trying to handle the OnItemCommand event for the grid, then go through each column to see if there is a value in the textbox and then apply the filter manually there. However I'm stuck on how to generate the FilterExpression and how to check the which search option is selected (contains, startswith etc...)
Is this the correct direction or is there a better way to do this?

RadGrid Paging Error in _destroyTree

I'm using an older version of Telerik that doesn't have the ASP 4.0 fix and it's causing my grid control to throw an error when paging. The error is: Microsoft JScript runtime error: Object doesn't support property or method '_destroyTree'

I found a fix on these forums that works very well when used on a normal ASPX page...

<script type="text/javascript">

$telerik.disposeElement = function (element) {

if (typeof (Sys.WebForms) == "undefined")

return;

var prm = Sys.WebForms.PageRequestManager.getInstance();

if (prm && prm._destroyTree)

prm._destroyTree(element);

else if (Sys.Application.disposeElement)

Sys.Application.disposeElement(element, true);

};

Telerik.Web.UI.RadComboBox.prototype._removeDropDown = function () {

var slide = this.get_dropDownElement().parentNode;

slide.parentNode.removeChild(slide);

if (this._disposeChildElements)

$telerik.disposeElement(slide);

if (!$telerik.isSafari)

slide.outerHTML = null;

this._dropDownElement = null;

};

</script>

My problems is that I am using user controls on much of the site. If I place this in the ASCX file, I get the same error as if I didn't have it there. If I place it in the ASPX that the user control is added to, I get this error: Microsoft JScript runtime error: Unable to get value of the property 'prototype': object is null or undefined most likely because the user control with the grid isn't loaded yet.

I can place the script inside an IF statement... if (Telerik.Web.UI.RadComboBox != null) { } and that gets rid of the prototype error, but it acts like the script isn't there because I still get the original _destroyTree error.

Can someone tell me what I need to do in order to make this work inside a user control? Here's the layout of my pages...

Master Page with update panel and placeholders.
- Inside one placeholder, I have a sidebar where I have an accordion menu.
  - This placeholder is filled in with an ASPX page.
- Inside the other placeholder, I have the main content area.
  - This placeholder is filled in with an ASCX user control based on what is clicked on the menu in the first placeholder.
  - Separate user controls are loaded dynamically based on the menu selection.
  - The user controls in this placeholder are where my grids are that need paging.

So what I need is to include the fix script in each user control that uses a grid so that I can page. If it were possible to include it on the master page so I don't have to put it on every user control, or if I could put it on the ASPX page that is in the first placeholder and have it work even when a new user control is loaded, then that would be great. But I don't mind including it in every user control if that is what's needed for this to work. I can also include a .JS file if that is what's needed. Keep in mind that these are inside an update panel, so the postback will be asynchronous in case that matters.

Any help would be greatly appreciated. It was decided that we wouldn't be updating Telerik, so I'm stuck with trying to make this work with just the script fix. This is really the only issue I'm having with Telerik and 4.0 with our site, so there isn't enough incentive to buy a newer version.

Just as a reminder, the script above works perfectly when used on a normal ASPX page that has the grid right on it rather than the grid being on a user control that is loaded later.

grid question

Hi,
I am new to telerik grid.
This is what I am trying to do. I want to place a combo box or drop down box in a cell of a grid. however, the grid is only being populated in the codebehind.
>>

List<KI_Controls.KI_Multimedia> oPrimaryMM = oPrimaryContact.GetAllMultimedia();

BindingList<cKIWebMultiMediaContent> Populatelist = new BindingList<cKIWebMultiMediaContent>();

for (int i = 0; i < oPrimaryMM.Count; i++)

{

cKIWebMultiMediaContent otemp = new cKIWebMultiMediaContent();

otemp.MultiMediaType = oPrimaryMM[i].Multimedia_Type;

otemp.MultiMediaText = oPrimaryMM[i].Value;

Populatelist.Add(otemp);

}

gridMainMultimedia.DataSource = Populatelist;

So this automatically creates 2 columns. MultiMediaType and MultiMediaText.

I want to make the MultiMediaType a dropdown and load it manually.

I see you have a lot of samples using datasources and design time binding. Do you have a simple dropdown grid example which all is unbound?

The server method getresources and getappointments failed

Hi,

I am using the Telerik Scheduler on my site. At the moment, I am doing local testing. My

The server method getresources failed
The server method getappointments failed

Now I am using WCF. I have the service interface and implementation in the website project and my .svc file points to this service (path is fine).

My service implementation looks like this:

    
              [ServiceContract(Namespace = "")] 
        
                [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
        
                [ServiceBehavior(IncludeExceptionDetailInFaults = true)] 
        
                public class Scheduler 
        
                { 
        
                    private WebServiceAppointmentController _controller; 
        
                    private WebServiceAppointmentController Controller 
        
                    { 
        
                        get 
        
                        { 
        
                            if (_controller == null) 
        
                            { 
        
                                _controller = 
        
                                    new WebServiceAppointmentController( 
        
                                        new XmlSchedulerProvider(HttpContext.Current.Server.MapPath("~/Content/Schedule.xml"), 
        
                                                                 false)); 
        
                            } 
        
                            return _controller; 
        
                        } 
        
                    } 
        
                    [OperationContract] 
        
                    public IEnumerable<AppointmentData> GetAppointments(SchedulerInfo schedulerInfo) 
        
                    { 
        
                        return Controller.GetAppointments(schedulerInfo); 
        
                    } 
        
                    [OperationContract] 
        
                    public IEnumerable<AppointmentData> InsertAppointment(SchedulerInfo schedulerInfo, AppointmentData appointmentData) 
        
                    { 
        
                        return Controller.InsertAppointment(schedulerInfo, appointmentData); 
        
                    } 
        
                    [OperationContract] 
        
                    public IEnumerable<AppointmentData> UpdateAppointment(SchedulerInfo schedulerInfo, AppointmentData appointmentData) 
        
                    { 
        
                        return Controller.UpdateAppointment(schedulerInfo, appointmentData); 
        
                    } 
        
                    [OperationContract] 
        
                    public IEnumerable<AppointmentData> CreateRecurrenceException(SchedulerInfo schedulerInfo, 
        
                                                                                  AppointmentData recurrenceExceptionData) 
        
                    { 
        
                        return Controller.CreateRecurrenceException(schedulerInfo, recurrenceExceptionData); 
        
                    } 
        
                    [OperationContract] 
        
                    public IEnumerable<ResourceData> GetResources(SchedulerInfo schedulerInfo) 
        
                    { 
        
                        return Controller.GetResources(schedulerInfo); 
        
                    } 
        
                }

And the aspx:

    
                  <telerik:RadScheduler ID="RadScheduler1" runat="server" Skin="Black" Visible="true" SelectedDate="2009-02-02" 
        
                                    Width="1043px"> 
        
                                <Localization AdvancedAllDayEvent="All day"></Localization> 
        
                                <AdvancedForm DateFormat="dd/MM/yyyy" TimeFormat="HH:mm"></AdvancedForm> 
        
                                <WebServiceSettings Path="Service.svc" /> 
        
                                </telerik:RadScheduler>

These errors appear even if I press the buttons on the control.

What am I missing?
