referencing your example:

http://demos.telerik.com/aspnet-ajax/listview/examples/definingstructure/declarativedefinition/defaultcs.aspx

you use this bit of markup:

  <LayoutTemplate>

                    <div
class="RadListView RadListView_<%#Container.Skin %>">

When I use the exact same code in my page the result renders as:

  <LayoutTemplate>

                    <div
class="RadListView RadListView_Default">

Even though the page is using the Sunset skin and buttons are rendering on the page properly with the Sunset skin.

If I hard code this in the page:

  <LayoutTemplate>

                    <div
class="RadListView RadListView_Sunset">



It works exactly as I want (but obviously won't work if we change the site's Skin).

Javascript and Stepping Through All RadDocks

I have implemented a portal page that allows users to position docks in three zones or float additional docks around the interface. This allows users with different screen resolutions to make use of their full screen and not be bound to our web portals sizing when having multiple docks on the screen.

To facilitate this I have written a script to ensure that users cannot move floating docks outside of the current screen bounds. However, the problem I am running into is losing docks when the browser window is resized. Tapping into a resize event handler for the browser is easy enough but I can’t find a command to cycle through all the open (or just floating) RadDocks to get their current positions so I can reposition them based on the screen resize.

Is there a command similar to cycling through a DockState in C for Java on the client side???

TIA

RadTextBox visibility issue

I am using the ASP.net version of the rad controls (RadControls for ASP.NET AJAX Q1 2011 SP1). I have a RadComboBox that, when the value is set to Other, should display a RadTextBox for data entry, here is the definition and JavaScript i am using:

<telerik:RadComboBox runat="server" ID="rcbIndustry" OnClientSelectedIndexChanged="OnClientSelectedIndexChanged" Skin="Black" Width="269" EnableEmbeddedSkins="false" />

<span id="tmp"></span>

<telerik:RadTextBox runat="server" ID="rtbIndustryOther" Skin="Black" Width="250" EnableEmbeddedSkins="false" />

<script>

function OnClientSelectedIndexChanged(sender, eventArgs) {

if (eventArgs.get_item().get_value() == 'Other') {

$find("#<%= rtbIndustryOther.ClientID %>").set_visible(true);

$("#tmp").html('<br>');

}

else {

$("#<%= rtbIndustryOther.ClientID %>").set_visible(false);

$("#tmp").html('');

}

$find("#<%= rtbIndustryOther.ClientID %>").set_visible(false);

</script>

The last line in the script ($find("#<%= rtbIndustryOther.ClientID %>").set_visible(false);) immediately throws an error:
"Microsoft JScript runtime error: Unable to get value of the property 'set_visible': object is null or undefined"

What am I doing wrong as this is driving me nuts...

Noddy is in da house

Yes, it's time for another dumb questions from yours truly.

I'm often surprised by how many times I find myself doing something for the first time, even though I've been doing this kind of work for a while now. Anyhow, here's the thing. I have a page with code on it that includes this ...

<telerik:RadScriptBlock runat="server" ID="RadScriptBlock1" >

<script type="text/javascript">

$(document).ready(function ()

{

var addEditEventDialog = new CalendarAddEditEventObject();

});

</script>

</telerik:RadScriptBlock>

The constructor of the object being created includes code to attach a couple of client-side event handlers and it all works fine. Until, that is, my page does an Ajax callback. At this point my handlers stop working.

Now, I've found a workaround but I'm unsure if it is the right work around. I've added RadScriptBlock1 in to the set of updated controls in the AjaxManager.

What should I be doing?

Pop up on Drag and Drop

I've run out of ideas on how to do this so I'm hoping one of you will give me an idea.

What I'm trying to do, at the request of our user community, is have a popup open when a user drags/drop a row so they can enter some information.

I'm using jQuery and some jQuery plug-ins in trying to accomplish this, everything works independently but when I try to incorporate it with the drap event it doesn't work.

I've tried squirting the javascript at the end of the rowdrop event of the grid and it does trigger my javascript and I've traced it and it should popup my window but it doesn't, I suspect that the javascript is being triggered at the wrong time in the sequence of events.

Any help would be appreciated.

All I need is a popup with a text area and a OK/Cancel that is triggered at the end of the dropping of a row.

Thanks

Pass parameter to webservice on node expand

Hi,
I am using the webservice method of populating my radtreeview as it was described as the most efficient way to load large amounts of data. So the signature of my webservice method is:

[WebMethod]
public RadTreeNodeData[] WebServiceMethodName(RadTreeNodeData node, object context)

However, the nodes that I am populating the tree with depend on the security access of the user that is logged in to my application..
Is it possible to pass additional parameters to the webservice method? Or must I use a ServerSideCallBack method to populate the tree? I am hoping that I can still use the webservices functionality... I would like to pass a signature like this to my webservice method:
[WebMethod]
public RadTreeNodeData[] WebServiceMethodName(RadTreeNodeData node, object context, object userSession)



I look forward to your response. Thank you!

Charts Programmatically

I have a used one of your chart demonstrations and require a little help.

DataTable table = PageAccess.CountOfEnquiriesBetweenDates(startDate, endDate);

var c = table.Rows.Count;

RadChart radChart = new RadChart();

radChart.ChartTitle.TextBlock.Text = "Enquiries";

radChart.Skin = "DeepGray";

var chartSeries = new ChartSeries {Name = "Enquiries", Type = ChartSeriesType.Bar};

//It works when I just put in a value

chartSeries.AddItem(c, "Enquiries");

from the code above I have executes a stored procedure retruned as a DataTable and I am then counting the number of rows in the table. I need this value to be in the graph data. I have tried Convert.ToDouble(c), I am using VS 2010. Can someone shed any light on what I have done wrong?

Many thanks

Simon

GridDropDownColumn & Binding to Non-foreign Key Columns

Hello,

Imagine two tables, each with two columns.

Operations

UserId

StartedBy

Users

Id

UserName

Operations.UserId is a FK to Users.Id. All columns are integers.

This works:

<telerik:GridDropDownColumn

DataField="UserId"

DataSourceID="UsersDataSource"

HeaderText="UserId"

ListTextField="UserName"

ListValueField="Id"

UniqueName="UserId">

</telerik:GridDropDownColumn>

This doesn't:

<telerik:GridDropDownColumn

DataField="StartedBy"

DataSourceID="UsersDataSource"

HeaderText="Started By"

ListTextField="UserName"

ListValueField="Id"

UniqueName="StartedBy">

</telerik:GridDropDownColumn>

Here's the DataSource:

<asp:EntityDataSource

ID="UsersDataSource"

runat="server"

ConnectionString="name=MyEntities"

DefaultContainerName="MyEntities"

EnableFlattening="False"

EntitySetName="Users"

EntityTypeFilter="User"

OrderBy="it.[UserName]">

</asp:EntityDataSource>

I know the UserId works because it is a foreign key but the second "StartedBy" is just a normal Int32 column in the Db that I have no control over (i.e. no relationship is or will be defined).

Normally, I'd just shrug and roll some code-behind but I'd much rather solve this in the declarative manner.

What is the simplest way I can get my StartedBy dropdown to bind via the value recorded in Operations.StartedBy?
