Menu Items do not exist on GoDaddy in Page_Load

I have nested RadMenuItems hard coded in an aspx file with 3 different but similar menus. Under a certain condition I need to remove the second menu item in each menu which works fine in the Visual Studio 2013 test environment. When I deploy to GoDaddy, remove on the third menu does not work in Page_Load.

GoDaddy the items in the third menu in the aspx file are not fully instantiated in Page_Load.

I was forced to code to check if the hard coded menu items exist and abandon the remove to avoid run-time errors.

if (JoinButtonMenu.Items.Count > 2 && JoinButtonMenu.Items.Count > 2) {

JoinButtonMenu.Items[1].Items[1].Remove();

}

<telerik:RadContextMenu ID="JoinButtonMenu" CssClass="RadContextMenu3" runat="server">

<ExpandAnimation Type="None" Duration="0" />

<CollapseAnimation Type="None" Duration="0" />

<Items>

<telerik:RadMenuItem Text="Edit" NavigateUrl="javascript:MenuItemSelected('Edit');" PostBack="False" ></telerik:RadMenuItem>

<telerik:RadMenuItem Text="Insert" PostBack="False" >

<Items>

<telerik:RadMenuItem Text="Insert Display Text..." NavigateUrl="javascript:MenuItemSelected('AddText');" PostBack="False" ></telerik:RadMenuItem>

<telerik:RadMenuItem Text="Insert Checkboxes..." NavigateUrl="javascript:MenuItemSelected('AddChecks');" PostBack="False" ></telerik:RadMenuItem>

....

The menu items missing in the Page_Load code all show up fine in the page including the one I need to get rid of.

Any ideas how to work around this problem and why it is happening?

Responsive DetailTable

Hello there,

I am using a RadGrid that contains one DetailTable. The MasterTable is set to 100% total width and the DetailTable to 95%. In Details table i have a column of long string (like $0000,0000,000,00). This column stretches out the detail table beyond the Master Table in Mobile or Tablet View (testing using chrome inbulit simulators). If i set the TableLayout property of DetailTable to fixed, then it crops the header and text of some columns. I can set the columns to AutoResize mode but don't want to follow this approach.

Is there any better approach where everything will become responsive in the Mobile and Tablet view? Please help

thanks in advance

Help With Big Data Sets

We would like to display data from ESRI Shapefiles with up to 200,000 points and are wondering if this is possible with the asp.net ajax RadMap.

Right now, we're looking just at performance with a RadClientDataSource loading from a JSON file with 40,000 Points displayed as simple black circles. Panning is fairly fast, but zooming in or out one level takes about 4 seconds, even when none of the points are in view.

I've seen a lot of information on the Silverlight and WPF forums about getting decent performance with ~200,000 points as long as very few are in view at one time, which would be acceptable, but unfortunately we cannot use these platforms.

Does the UI for ASP.NET AJAX have anything like the dynamic layer that would improve performance when a lot of data is out of view? Or are there any other strategies to improve performance when this much data needs to be loaded?

Thanks in advance,
-Andrew

ComboBox MultiColumn with checkBox problem

Hi,
First i'm sorry for my bad english, I'm not really good. But I will try to explain my problem for you can understand.

In the project, we have a RadComboBox who get data by a ItemRequest. This comboBox serve for select a Person who are view in DataList

<telerik:RadComboBox ID="radPersonCombo" runat="server" Width="400" DropDownWidth="700" Height="300" AccessibilityMode="true" AutoPostBack="false" EnableScreenBoundaryDetection="true" EnableVirtualScrolling="true" ItemsPerRequest="10" ShowMoreResultsBox="true" EnableLoadOnDemand="true" OnItemsRequested="radPersonCombo_ItemsRequested" CheckBoxes="true" CheckedItemsTexts="FitInInput">

<HeaderTemplate>

<table style="width: 682px" cellspacing="0">

<tr>

<th style="width: 32px"></th>

<th style="width: 125px"><asp:label ID="radTitleLN" runat="server"><%= LocalizationTools.RM.GetString("lblName") %></asp:label></th>

{...}

</tr>

</table>

</HeaderTemplate>

<ItemTemplate>

<table style="width: 682px" cellspacing="0">

<tr>

<td style="width: 32px"></td>

<td style="width: 125px"><%# DataBinder.Eval(Container, "Attributes['LastName']")%></td>

{...}

</tr>

</table>

</ItemTemplate>

</telerik:RadComboBox>

<asp:datalist id="dtlPerson" runat="server"> {...} </asp:datalist>

That comboBox can have more 1000 DataItem. For this reason we use EnableLoadOnDemand, but the EnabledLoadOnDemand don't preserve item server-side.

When I check the elements and I close the ComboBox. If AutoPostBack option is True.

I get the error:

Index was out of range. It must not be negative and must be less than the size of the collection.

Parameter name: index

I tried using the following example. However, this example remains the client side. And when I try to spent AjaxRequest to call the Fill methods that data DataList. Nothing displays.

http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/templates/defaultvb.aspx

Otherwise these is possible to align the check box in the center of the element? Since it is not included in my Template. (See Image CheckBoxMiddleAlign)

The desired final result should be like the image finalResult attached.

Filter Template Using the RadCombobox

I am having issue in implementing the RadCombobox filter from server side. I am binding the Radcombobox to the need datasource. But no luck in making the filters work. If I tried doing the static Combobox list and call with javascript it is ok. But I have to implement it from the server side.

Anyhelp will be much appreciated. I searched the forums, but couldn't find a demo using the need datasource for the MVC pattern.

When I binded RadComboBox with collection (List) in the code behind..
The filtering didn't work.. I binded the RadComboBox in
GridItemDataBound or GridItemCreated event.. But no luck..

Any help.. will be very much useful to me.. I spent nearly two days but I
didn't any direction... I'm nearing to my deadline.. so I have no other
option left out other than this forum..

Thanks,

Sachi.

Tabs stop working after refresh

I've come across an issue where my TabStrip stops working in Firefox if the page is refreshed via F5 instead of ctrl-F5. I dont have a spot to test if it happens after postback or not. I'm aware that I dont need the JS function to switch tabs..it was just an attempt to fix the issue. I put an alert() in the JS and found its not going into the function at all after a F5 refresh. Do I need to run a reset function or something on the usercontrol pageload or maybe tooltip load? Again, this appears to only be a FF issue...IE works as expected. Using Version 2008.1.515.20.

    
            <rad:RadTabStrip ID="radQPTabs" runat="server" MultiPageID="radmultipage" BorderWidth="0" 
        
                            OnClientTabSelected="onSelectedQuickPeekTab"  Skin="Vista"> 
        
                            <Tabs> 
        
                                <rad:RadTab Text="Price" Selected="true" Width="95px"> 
        
                                </rad:RadTab> 
        
                                <rad:RadTab Text="Details" Width="95px"> 
        
                                </rad:RadTab> 
        
                            </Tabs> 
        
                        </rad:RadTabStrip>

    
            function onSelectedQuickPeekTab(sender, args) { 
        
                var tabs = args.get_tab(); 
        
                var strTabText = tabs.get_text(); 
        
                if (strTabText.indexOf("Price") > -1) { 
        
                    tabs.set_selectedIndex(0); 
        
                } else if (strTabText.indexOf("Details") > -1) { 
        
                    tabs.set_selectedIndex(1); 
        
                } 
        
            }

RadGrid and PopUp editing

From what I understand, if I have a grid with EditMode="EditForms" with a WebUserControl and everything works correctly, the only thing I have to change for this WebUserControl to turn into a PopUp windows is the EditMode="PopUp".

The reason I ask is that I have already tried this, but I get no PopUp screen.

You can see the attached screen for what I get instead (third record).

I would appreciate any help.
