Access a tab javascript variable from parent...

Hello...

I have a main page with a lot of content and a RadTabStrip with 2 tabs...
I load a local page on my Tab. That page has a javascript variable called "map"

So, In main page I have a html button. When the user click it I´m supposed to get the Iframe variable "map" (from tab) and play with it...
How can I get that variable ?

Thanks

Treelist performance

I have inherited an application from a previous developer and I am having problems with the speed of the RadTreeList he has previously implemented.

The Treelist is a representation of a dealer hierarchy where the sub branches roll up to a principal dealer within a country.

Eg Principal Dealer 11020000

Has branches: 11020001, 11020002, 11020003

For each row we are displaying name and address information as well as image buttons that allow a dealer to be selected/assigned to a role holder or for all dealers for a principal to be selected at principal level.

This is using the NeedDataSource event.

Now I am caching data from my SQL Server 2008 datasource wherever I can but I am finding that expanding nodes at principal level and performing updates is painfully slow. Even at it’s largest for a single country the treelist only has around 2000 records and the round trips to the server to get data and perform updates look pretty quick.

I have been through all of the performance tips on the site but nothing seems to be improving it i.e. RadCompression etc.

Can you suggest anything that might be available to improve performance?

Menu Item Parent Child Relationship not working

Hi,

I'm using Telerik RadControls Q1 2008. I have a Rad Menu on the masterpage of my application and i'm trying to bind it to a linq datacontext.

The binding works fine but my problem is That Child Items are always displayed as root items.

I have checked that ParentId of all roots items is NULL and of all the child items is that of the assigned parent.

Below is the code :

Private Sub LoadMenuItems()

Dim MenuDC As New MenuItemDataContext

RadMenu1.DataSource = MenuDC.usp_TABLE_MENU_ITEM_Select().ToList()

RadMenu1.DataBind()

End Sub

<telerik:RadMenu ID="RadMenu1" runat="server" Skin="Office2007" DataFieldID="MENU_ITEM_ID"

DataFieldParentID="PARENT_ID" DataNavigateUrlField="PAGE_URL" DataTextField="MENU_ITEM_NAME"

DataValueField="MENU_ITEM_ID">

<DefaultGroupSettings ExpandDirection="Down" />

<CollapseAnimation Type="OutQuint" Duration="200"></CollapseAnimation>

</telerik:RadMenu>

I do not know what i'm missing here.

Changing Style/Border of DateInput

Hi,

I am trying to change the border and background DateInput control. I would like to change the border to red with yellow background, and the triangle with ! in middle if possible or something to that affect. I tried a Custom Validator but with no luck. I would settle for a red border around the Data Input text box.

I have tried every which way; but to no success..Can this be done? If so, any suggestions?

Thanks in advance,
Gary

Radgrid Issue with horizontal scroll, Merged Headers and pagination.

Hi,

1) I want a header in which there will be one main heading and under it there can be sub headings, the main header will span across its multiple sub headings, user can sort the grid by clicking on the sub headings. Please refer to the "UI.jpg"

2) The requirement is like i will be needing the Radgrid as usercontrol, which we will bind on Page. when we run the page, the screen looks fine except for the Merged Columns where in we need the headings and the Subheadeing, refer "Screenshot1.JPG"

The second issue which we I am facing is, The rad grd will have horizontal scroll and first 3 columns would be frozed.
But when we try to freeze the columns we face the following issues:

a) When we scroll, the complete alignment of the grid gets messed up, and one Grid line remains there and shows up in the middle of all scrolling columns. Refer "Screenshot2.JPG" .

b) After we scroll, the horizontal scroll itself disappears. Refer "Screenshot3.JPG" .

c) If we change the page size in pagination, the pagination also disappears. Refer "Screenshot4.JPG" .

Please refer to the code as well, We have created a user control "uclFleet.ascx" which we register in our page "Test_Fleet.aspx".

Please reply on an urgent basis.

Thanks.

Model Validation with Multiple Grids in TabStrip Control

Hi,
       I have an MVC application with a view which has a Telerik TabStrip Control. The TabStrip has 3 tabs: the First tab contains three Telerik Grids, and the other two tabs one grid each. All The values which are being bound to the grid are being validated in the Model. Each of the grids has Edit button present in each row. After editing the fields in the grid's row when insert/ save is clicked, the model validation is supposed to be fired stopping from executing the code in the controller. The problem is that validation works only for the first grid of the first tab and not for the remaining 4 grids in the View . Below is the code

VIEW:
<% Html.Telerik().TabStrip()
           .Name("captabletab")
           .Items(tabstrip =>
           {

               tabstrip.Add()
               .Text("Tab1")
                .Content(() =>
                {%>
                    <br />
                    <span class="..."></span>
                    <br />

My MODEL has the classes - Class1, Class2, Class3, Class4, Class5 with properties which have validation using Attributes . Sample below:

public class Class1
    {

        public int ID { get; set; }

        [DisplayName("Column1")]
        [Required(ErrorMessage = "The Column1 field is required")]
        [RegularExpression(@"\b\d+\b", ErrorMessage = "The Column1 field should be a Positive Integral Value.")]
        public int Col1{ get; set; }

        [DisplayName("Column2")]
        [StringLength(20, ErrorMessage = "The length of Column2 should be less than 20 characters.")]
        [Required(ErrorMessage = "The Column2 is Required.")]
        public string Col2{ get; set; }

Property is not numeric exception with Radchart using ObjectDataSource

Requirements
RadControls version
.NET version : 3.5
Visual Studio version : 2008
programming language : C#
browser support	all browsers supported by RadControls

PROJECT DESCRIPTION
I get the below error while using RadChart using ObjectDataSource. Duration is a Double field and not sure why its not being identified as numeric. Also tried Int32, Int64 & other options. Also just to test I tried replacing the Property name with some other text (which is not a property) the error change the same except for the change in property name.

note : Im using evaluation copy not sure if the issue is with this version.
