radprompt nested function '_functionality is undefined'

I posted this question on StackOverflow: http://stackoverflow.com/questions/26935565/cannot-read-property-length-of-null-using-sender-set-selectedtogglestateinde

It would appear that this telerik thread holds some relevance: http://www.telerik.com/forums/radbutton-javascript-error

Note this issue is in the same project as the RadCombo thread I made: http://www.telerik.com/forums/client-side-eventargs-are-mutable

Where 'navigating' the client state (control state or view state) using either sender or the event argument is not an issue.

If you could answer this question on SO, I would be greatful, but I do have a general question for this thread post. What is the underline mechanics of how telerik uses the client functions 'get_selectedToggleStateIndex()' or 'get_toggleStates()'.. what is '_functionality' and why is it null in my implementation (i.e. nested function as a promptcallback function)?

Problem to sort GridTemplateColumn with Image control

Hi,

I'm using a GridTemplateColumn with an Image control in ItemTemplate. I'm using the ItemDataBound event to set the Image background, this all works fine. However when I click on a column to sort all the text columns are sorted correctly but the images do not move.

Here is my code:

ASPX:

<telerik:RadGrid ID="radGrid1" runat="server" AllowSorting="true" OnNeedDataSource="radGrid1_NeedDataSource" OnItemDataBound="radGrid1_ItemDataBound">

<MasterTableView EditMode="Batch" AllowSorting="true">

<Columns>

<telerik:GridClientDeleteColumn ConfirmText="Are you sure?" ImageUrl="~/Images/icoDelete.png" />

<telerik:GridTemplateColumn HeaderText="Color" UniqueName="RangeColor" DataField="RangeColor" ItemStyle-HorizontalAlign="Center">

<ItemTemplate>

<asp:Image ID="imgRangeColor" Height="15" Width="100%" runat="server" />

</ItemTemplate>

<EditItemTemplate>

<telerik:RadColorPicker ID="colorPickerTemplate" runat="server" OnClientLoad="PickerLoad" ShowIcon="true" ShowEmptyColor="false" />

</EditItemTemplate>

</telerik:GridTemplateColumn>

</Columns>

</MasterTableView>

<ClientSettings>

<ClientEvents OnBatchEditGetCellValue="OnBatchEditGetCellValue" OnBatchEditSetCellValue="OnBatchEditSetCellValue" OnBatchEditGetEditorValue="OnBatchEditGetEditorValue" OnBatchEditSetEditorValue="OnBatchEditSetEditorValue" />

</ClientSettings>

</telerik:RadGrid>

NeedDataSource and ItemDataBound events:

protected void radGrid1_NeedDataSource(object sender, GridNeedDataSourceEventArgs e)

{

myTable = new DataTable();

myTable.Columns.Add("RangeMin");

myTable.Columns.Add("RangeMax");

myTable.Columns.Add("ColorAux");

if (ViewState["Table"] != null)

myTable = (DataTable)ViewState["Table"];

radGrid1.DataSource = myTable;

ViewState["Table"] = myTable;

}

protected void radGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem & e.Item.IsDataBound)

{

GridDataItem item = (GridDataItem)e.Item;

string color = ((DataTable)ViewState["Table"]).Rows[item.ItemIndex][2].ToString(); //Get ColorAux value

(item["RangeColor"].FindControl("imgRangeColor") as System.Web.UI.WebControls.Image).BackColor = System.Drawing.ColorTranslator.FromHtml(color);

}

Any sugest how I can fix that problem?

Thanks

How to load custom Web User Controls

Hi,

I have the following situation: I have multiple self-developed Web User Controls (ascx) in my web application. The user controls are holding different logic, for example a rather complex contact form.

Every page's content on the website, is edited throud RadEditor. Now I need a flexible way to dynamically load page content including one, two, three, x of my own custom user controls....

How can i accomplish this in a neat way with the RadEditor?

My own solution is, in the RadEditor's contentarea, to insert a reference to the user control like %%control:MyFancyUserControl%%, and then at runtime search for %%control:MyFancyUserControl%% and load the control when the page is rendered.

Gauge Border

Is there a way to create a circular border around the gauge as opposed to the wrapper? I'm getting a square border but I would like the border to go around the gauge. I attached an example (gauge1) of what I'm getting and I attached an example (gauge2) of what I am trying to accomplish. Thank you.

Rad Button - IE11 - Disable Issue

Setting Enabled = False is not properly styling the RadButton. The disabled="disabled" attribute correctly shows in the generated markup (which causes the correct functionality of it not being able to be clicked); however, the outer anchor tag is not styled with the "rfdInputDisabled" class. I can only reproduce the issue in IE11 (I'm on 11.0.9600.17358). I have a code sample; however, the file filter is not allowing me to attach a .zip file.
