Hi,

We have implemented date sorting for the RadFileExplorer in the Image Manager tool of RadEditor. With this, the contents of our configured image path are sorted according to the date they were uploaded. We have also enabled paging for the explorer. Currently we have a problem when the parent 'Images' path has both files and sub folders. In this case, RadFileExplorer seems to be always picking folders first rather than files. So, for example, if my page size was 5 and I have two subfolders and 5 files in my directory, the first page always shows the directories. This has become a problem when a new file is uploaded. We expect to see it at the head of the first page. However, we find that it is the head of a page somewhere down the line. This is happening only when there are subfolders in the parent directory.

Please advise!

Issues with xmldatasource databind in listview

I have a ListView bind to xmldatasource, but I cannot make it work as the online demo does, it keeps saying "

DataBinding: 'System.Web.UI.WebControls.XmlDataSourceNodeDescriptor' does not contain a property with the name 'Street'.

"..when I changed the syntax from <%#Eval("Street")%> to <%#XPath("Address/Street")%>, it kinda works but only pull out data under the first child node, the rest never got databinded. The xml file is like below:

<data>

<Address>

<Id>1000</Id>

<Street>1234 S 1st St. </Street>

<City>LOS ANGELES</City>

.......

</Address>

<Address>

......

</Address>

</data>

Here is my xmldatasource:

<asp:XmlDataSource ID="XmlDataSource1" runat="server"

DataFile="~/sample1.xml" XPath="data"></asp:XmlDataSource>

Any suggestions?

Thanks a lot!

slider drag handle - not dragging

**UPDATE** Doesn't seem to work when adding it into a MasterPage Content page in IE7 only in FireFox it works??
I'm trying to get the RadSlider drag handle to move when clicking on it and dragging it horizontally either direction with no luck. Using the side arrows or clicking on the slider bar will move the handle, but dragging the handle itself doesn't work. Not sure what I'm missing here or if I'm supposed to implement some javascript here to allow for that functionality?

<telerik:RadSlider ID="RadSlider0" runat="server" ItemType="None" MinimumValue="0" MaximumValue="100" SelectionEnd="100" Value="0" OnClientSlide="clientSlide()"

ShowDragHandle="true" AnimationDuration="300" Height="20px" Width="106px" Skin="Telerik" OnClientValueChange="HandleValueChange">

</telerik:RadSlider>

RadSlider0.Value = (

Int32)dr[3];

RadSlider0txt.Visible =

true;

RadSlider0.Visible =

true;

[Solved] Showing appointments in a grid

I have an app wherein I store appointments in a DB.

I - normally - show the appointments in RadScheduler. However, there are occasions when using the scheduler is not the most appropriate too, for example, when the use queries the data base for a period covering more than 1 month.

In these cases, I use RadGrid to display the results of the query and this works just fine.

[wait for it]

But, I now have recurring appointments and these are stored using the recurrence rule in the master appointment. Is there a way for me to show the occurrences of these recurring appointments in a grid?

I can think of doing it:

Read the DB and set the DataSource of the Scheduler to the query result and then use the Scheduler's Appointments property as a DataSource for the grid.
Read the DB and set the DataSource of the Scheduler to the query result and use the AppointmentDataBound event to create a new List<> to use as the DataSource of the grid.

I haven't yet tried either of these, 'cos I'm sure I've seen an demo, or Code Library article on this very subject, but I'll be damned if I can find it.

FWIW, I prefer the idea of the 2nd of the 2 options above as the AppointmentDataBound event gices me access to the DataItem used to create the appointment in the first place, can I have a lot of extra data in that object that I would, otherwise, have to query the DB again for.

Load RadGrid using ajax request

Hello,

I have a custom ascx controls contains RadGrid and RadChart.

The control is loaded into ajax panel using ajax request

protected void RadAjaxPanel2_AjaxRequest(object sender, AjaxRequestEventArgs e) 
        { 
            if (e.Argument == "InitialLoad") 
            { 
                var auctionTotals = LoadControl("~/core/Informers/CurrencyRates.ascx"); 
                auctionTotals.ID = "CurrencyRates"; 
                panel2.Controls.Add(auctionTotals); 
              } 
        }

Inside the user control every grid row has a related chart dislayed when this row is selected.

function <%=ClientID%>_grid_OnRowSelected(sender, args) {

<%=ClientID%>_selectChart(parseInt(args._itemIndexHierarchical));

}

Here is how the event handler is added

var events = grid.ClientSettings.ClientEvents;

events.OnRowSelected = ClientID + "_grid_OnRowSelected";

Everything works just fne if the control is used on the aspx page (like a normal aspx control). But as soon as I try to load this control dynamically using ajax panel (using the first code snapshot), I get a javascript error: content_CurrencyRates_grid_OnRowSelected is not defined

I am a bit confused why the event handler is not binded to the grid in this scenario. Should this function be placed in some other part of the ascx control?

Thanks,
Andrei

HeaderContextFilterMenu For GridCheckBoxColumn

Hallo!
We have a RadGrid which displays several columns of type checkbox, bound and template columns. The header filter context menu displays two checkboxes which are present in the filter template for the checkbox column also for the columns which are not a checkbox column. (See attchment). Another problem with the header filter context menu is that for a checkbox column, the first condition filter checkbox is disabled und cannot be used as a filter. The second condition is not necessary for a checkbox column but is the only one which can be used. How can this be changed?
Solutions I am looking for:
1. Checkboxes in the filter context menu for non checkbox columns should not be shown.
2. There should be only one checkbox in the filter contet menu for a checkbox column.
warm regards

Server side OnTimeSlotClick event?

Hi,
I noticed there is a client side event called OnClientTimeSlotClick and there are few posts about how to get the time when somebody click on an empty slot on the schedule. But I really don't want to use client side event.

Is there a similar event for server side? I assume it's called OnTimeSlotClick, but I couldn't find it.

Thanks,
Dom
