Hello,

I am having hard time to code for RadTreeView in a RadComboBox. I am using VB.NET. I cannot see the RadTreeView instance at all
from the code behind. Even if I try the FindControl method! I have to dynamically populate the treenodes with data from SQL Server

ASPX code:
<span><telerik:RadComboBox ID="ddDocType" runat="server" Width="200px" ShowToggleImage="True" Style="vertical-align: middle;" >
    <ItemTemplate>
        <div id="div1">
    <telerik:RadTreeView ID="rtvDocType" runat="server" Width="300px" Height="250px">
        <DataBindings>
            <telerik:RadTreeNodeBinding Expanded="True" />
        </DataBindings>
    </telerik:RadTreeView>
        </div>
    </ItemTemplate>
</telerik:RadComboBox></span>

VB.NET code:

Dim tvDoc As RadTreeView = New RadTreeView()

tvDoc =

CType(FindControl("rtvDocType"), RadTreeView)

tvDoc.Nodes.Clear()

Here tvDoc gives a ERROR 'NullReferenceException'

How can I make it work. Is there any working example where the Nodes are dinamically added from code behind for the RadTreeView
in a RadComboBox?

Thanks,
Sanjay

Element vs. Attribute

I can get the tree list working fine when I use attribute based xml.
<catalog>
<catalogitem id="1" name="test 1"/>
<catalogitem id="2" name="test 2"/>
</catalog>

but the xml I'm getting from a web service is doing this:
<catalog>
    <catalogitem>
        <id>1</id>
        <name>test 1</name>
    <catalogitem>
    <catalogitem>
        <id>2</id>
        <name>test 2</name>
    <catalogitem>
</catalog>

I have no problem binding the RadGrid to the xml like the latter but I can't seem to figure out how to do it for a treelist.

Also, is there any way to start the parent id as 0 instead of null/empty??

Grid / Editing with External Form

I've seen a similar post for this back in 2009, but it was not solved.

I'm receiving an error on the Grid / Editing with External Form demo when I created locally.

Object reference not set to an instance of an object


Line 88:         protected void Page_Load(object sender, System.EventArgs e)
Line 89:         {
Line 90:             RadAjaxManager.GetCurrent(Page).AjaxSettings.AddAjaxSetting(RadGrid1, RadGrid1, PlaceHolder.FindControl("RadAjaxLoadingPanel1") as RadAjaxLoadingPanel);
Line 91:             //store the clientID of the grid to reference it later on the client
Line 92:             RadAjaxManager.GetCurrent(Page).ResponseScripts.Add(string.Format("window['gridId'] = '{0}';", RadGrid1.ClientID));

When I debug, I notice that placeHolder is still returning a NULL value:

private Control placeHolder;
        private Control PlaceHolder
        {
            get
            {
                if (placeHolder == null)
                {
                    placeHolder = this.Page.Master.FindControl("ContentPlaceHolder1");
                }
                return placeHolder;
            }

Any ideas?

Thanks, Trisha

Multiple issues using RadScheduler in MVC project

Hi,

I am using RadScheduler in MVC 3.0 project. I have few issues while using it. It would be of great help if you can direct me on the resolution for following:

1. How can I set MinutesPerRow property on server side? (As per another forum thread, MinutesPerRow cannot be set on client side).
2. I am trying to use GroupBy property to display multiple resources side by side in RadScheduler. I am using ResourcePopulationMode="ClientSide". But when I use GroupBy property, I get following Javascript error (in js file):

Microsoft JScript runtime error: Unable to get value of the property 'get_visibleRangeStart': object is null or undefined

3. I am trying to add a CheckBox control on the appointment so that it can be selected. But when I add <AppointmentTemplate> tag and add the markup it does not have any affect. Here is the markup that I am using:

<AdvancedForm Modal="true" />

<AppointmentTemplate>

<div>

<asp:CheckBox ID="EligibilityCheck" runat="server" Text="Eligibility" TextAlign="Left" Checked="false" AutoPostBack="true" />

<br />

<%#Eval("Subject") %>

</div>

</AppointmentTemplate>

I am using version 2011.1.519.40 of Telerik.Web.UI.dll

Thanks in advance!!

Get file size in javascript for IE

I am using mulitple uploader, and need to get the file size at client side when user selects the file.
Is there any direct method or property to get size?
For now I am using the below code, but it is not working in IE

function selectedFile(sender, eventArgs) {
   var inputs = sender.getFileInputs();
   for (i = 0; i < inputs.length; i++) {
                    if (navigator.appName == "Netscape") {
                        size = inputs[i].files[0].fileSize;
                    }
   else if (navigator.appName == "Microsoft Internet Explorer") {
                        var filepath = inputs[i].value;
                        var SizeINIE = User_book.GetFileSize(filepath);     //This always returns 0 as the file will not be existing on server
                        if (SizeINIE != null) {
                            alert(SizeINIE.value);
                            size = SizeINIE.value;
                        }
                    }
}
Can anyone provide me solution for this ASAP?

Update ComboBox on client side

Hi,
I try to find a way to update the RadComboBox on client-side with an existing JavaScript array.

To lower the number of server requests we introduced a JavaScript file where we created arrays of countries, states and cities. Those elements won't change so a server request is not necessary. Now we'd like to use the RadComboBox for selecting the country, state and city. However I haven't found an easy way to do this.

We have:
- ASPX file with 3 RadComboBoxes for country, state and city
- JavaScript file with array of countries, states and cities

When the user selects a country, a javascript method should choose the correct state array and fill the state combo box with the possible items. Same for the state and city.

Does anyone have an idea if and how we can do this?

Thanks,
Hilmar

Can Decorator Be Disabled for Dock?

I am using the RadDock control on a client website page where the decorator is also used. The Decorator has the capability to turn off the feature for certain control types. Is there any way to turn off the Decorator for a RadDockZone/RadDock?

Thanks in advance!
