What is the simplist way to determine whether the checkbox for a node has changed its state. Currently I use Javascript code to store changes in a variable and send the contents of that variable back to the server. I suppose what I am looking for is something like a "CheckboxChanged" property. It really shouldn't have to be necessary for me to write additional code to keep track of these changes. It should be built into the Treeview control. In typical scenarios, when a user checks or unchecks something, this will often result in having to add or delete something on the server. Without recording the state, I would have to first get what already exists on the server and compare it to the current treeview state and either add or remove stuff.

What is proper way to cancel update after exception?

Hello,
I'm using RadGrid 2009.3 with LLBLGenProDataSource2 data source control and the following settings:

grid.MasterTableView.EditMode =

GridEditMode.EditForms;

grid.MasterTableView.EditFormSettings.EditFormType =

GridEditFormType.AutoGenerated;

Whenever user attempts to Update a record that results in the exception, I handle the exception through ItemUpdated event:

    
                private static void grid_ItemUpdated(object source, GridUpdatedEventArgs e)  
        
                {  
        
                    if (e.Exception != null)  
        
                    {  
        
                        HandleInsertUpdateException((source as RadGrid), e, false);  
        
                        e.ExceptionHandled = true;  
        
                        e.KeepInEditMode = true;              
        
                    }  
        
                }

where HandleInsertUpdateException is my function for printing the error message.

The problem I'm faced with is this: whenever the user hits the Cancel link, the updated (incorrect) value still gets displayed in the grid.

What is the proper way to refresh the grid to have it display the original value whenever Update fails?

RadCalendar with EnableMultiSelect loses specialdays data upon navigation

This is the definition we have in .aspx

<telerik:RadCalendar ID="RadCalendar2" runat="server" Font-Names="Arial,Verdana,Tahoma"

ForeColor="Black" Skin="Outlook" Style="border-color: #ececec"

EnableViewSelector="True" AutoPostBack="false">

</telerik:RadCalendar>

A function with the following lines is called on pageload:

RadCalendar2.SpecialDays.Clear();

RadCalendar2.SelectedDates.Clear();

RadCalendarDay NewDay = new RadCalendarDay(RadCalendar2);

foreach (DataRow drrow in dtALLDates.Rows)

{

NewDay =

new RadCalendarDay(RadCalendar2);

NewDay.Date =

Convert.ToDateTime(drrow["CalendarDate"]);

NewDay.ToolTip =

Convert.ToInt32(drrow["SeatsAvailable"]) > 0 ? Convert.ToInt32(drrow["SeatsAvailable"]) > 1 ? drrow["SeatsAvailable"] + " seats are available" : "1 seat is available"

:

Convert.ToInt32(drrow["InSchedule"]) == 0 ? "Session not offered or it is a holiday." : "Seats are not available.";

Boolean bselect = Convert.ToInt32(drrow["SeatsAvailable"]) > 0 && Convert.ToBoolean(drrow["AllowEdit"]) == true ? true : false;

NewDay.IsSelectable = bselect;

if (Convert.ToBoolean(drrow["IsOpted"]) == true)

{

NewDay.IsSelected =

true;

RadCalendar2.SelectedDates.Add(

new RadDate(Convert.ToDateTime(drrow["CalendarDate"].ToString())));

}

RadCalendar2.SpecialDays.Add(NewDay);

}

When we navigate from one month to another month, the highlighted dates are cleared. I tried lot of things. But nothing working. Please help me to come out of this issue.

Thanks a lot in advance.

RadWindow caption problem in IE

I am using RadWindow in my Aspx pages. And there is a problem I've got:

The caption of window is displayed incorrectly in IExplorer. Look at samples from Explorer and Chrome.

Window is defined in Aspx as follows:

<radw:radwindowmanager runat="server">

<radw:RadWindow id="ARAjuda" title="Ajuda - Conhecimentos" Width="600px" Height="450px" Runat="server"

ReloadOnShow="false" Modal="true" Behavior="Move, Close" onclientshow="OnClientShow" ShowContentDuringLoad="true"/>

<radw:RadWindow id="SendConhecimento" title="Conhecimentos - Sugerir Novo Conhecimento" Width="500px" Height="350px" Runat="server"

ReloadOnShow="false" Modal="true" Behavior="Move, Close" onclientshow="OnClientShow" ShowContentDuringLoad="true"/>

</Windows>

</radw:radwindowmanager>

And is called to be shown as follows:

function ShowHelp()

{

window.radopen("Dialogs/Help.aspx", "ARAjuda");

return false;

}

The content of Help.aspx is about like that:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<title>Ajuda - Conhecimentos</title>

</head>

<body>

<tr>

<b>Conhecimentos</b>

</td>

</tr>

<tr>

Etiam sem libero, dictum vitae, lobortis sed, vehicula non, nibh. Donec quam. Ut lectus nulla, dictum et, vestibulum in,

</td>

</tr>

<tr>

<br />

<button onclick="CancelEdit();" type="button" class="mediumButton">Fechar</button>

</td>

</tr>

</table>

</form>

</body>

</html>

Any idea, how to fix it ?

Menu Slide items not showing properly in Firefox

Hi
The slide items of menu are showing in upward direction in FireFox even if there is plenty space at the below side of the menu. If there is no space to spread the slide items below the menu then it shows at the upward side, that is fine, but after that if we provide plenty space below the menu still the slide items shows at upward side.

The slide items behave properly in IE and Safari.

Please go through the attached file for more clarity

Please suggest me what i have to set for getting the menu working properly for FireFox.

Thanks

<telerik:GridTemplateColumn HeaderStyle-Font-Underline="true"     HeaderText="Category Name" HeaderStyle-HorizontalAlign="Center"
                            SortExpression="Name"     HeaderStyle-Width="170px" ItemStyle-HorizontalAlign="Left"
                            ItemStyle-VerticalAlign="Middle">
                            <ItemTemplate>
                                <asp:LinkButton ID="lblShortCode" OnClick="EditeRecord" CommandArgument='<%# Eval("RecordID") + "~" +Eval("ProgramCatId") %>'
                                    runat="server" Text='<%# Eval("Name") %>'></asp:LinkButton>
                            </ItemTemplate>
                            <ItemStyle VerticalAlign="Middle" BorderColor="#8AB3C9" BorderWidth="1px"></ItemStyle>
                        </telerik:GridTemplateColumn>

Thanks.
