Remove TagCloudItem

I have a question about removing a RadTagCloudItem. I have a TagCloud and i want it to behave like most clouds. For example, if i don't like a word in the cloud i want to right-click on the word and select from a pop-up menu remove it. And the word will be removing from the cloud i see(Client-side).

I have tried to click on the word i don't want and in server-side removing it, but it's very slow and it's not what i want. Because it's not obvious for someone else to click on the word in order to remove it.

Any propose?

RibbonBar inside table

Hi,



I am trying to put a RibbonBar inside a table cell. The reason for this is that 

I want to put things to the right of the ribbonbar. 

When I run the page the RibbonBar is not sized correctly. It is too small and

all buttons is not visible.



I can not set any width in pixels, the content is dynamic.



Does anyone know if it is possible to put a ribbonbar inside a table cell?



<

table width="100%" cellpadding="0" cellspacing="0" border="0">

<tr>

<td >

<telerik:RadRibbonBar ID="RadRibbonBar1" runat="server" Skin="Office2007">

<telerik:RibbonBarTab Text="Home">

<telerik:RibbonBarGroup >

<Items>

<telerik:RibbonBarButton Size="Medium" Text="Cut" />

<telerik:RibbonBarButton Size="Medium" Text="Copy" />

</Items>

Intercept "Expand" event for nested views and process the expansion by hand

I am having a bunch of issues trying to use data sources with radGrid nested views, therefore, I was wondering if there is an event I can intercept when clicking on the expand arrow so that I can, myself, retreive the data and display it for that particular item.

Also, when I do this, where should I store the information I get on other expanded items? Use a generic list and put it in the view state? If so, how would I render the whole grid when the postback is received? How do I walk through the hierarchy and update those items which where previously expanded?

Thanks

Cascading Combo Boxes > How To Get the Third Combo To Update?

I have read the sample and it was very helpful, but I guess I am missing something, because I cannot get the third combo to update properly.

In the attached sample, I have 3 combos: Content Area, Teacher Name, Student Name

When a user changes the Content Area, I want both combos to refresh. It is a true cascade, because the teacher name also determines the list of students.

For demo purposes, I have made it so the students lat names start with the same letter as their teachers. So, if you select [Mathematics], not only should [Euler, Leonhard] appear (which it does), but also his first student [Edwards, Ernie]. This does not happen. The student list remains for the previous teacher, until you manually change that second combo.

I am sure this is simple -- I am probably missing something on the control that would trigger the update to the third combo -- but I've been struggling with this for a few days now and need a more experienced set of eyes.

Suggestions are much appreciated!

RadEditor long content printing issue

When the content inside a RadEditor in a form is more than one letter page long is not printing properly, creating one or more page breaks before printing the content. I guess it has to be with the IFrame. What can I do to print the content continuously as the rest of my form?

Thanks,
JD

RadDateTimePicker Button Images Not Showing

I have a RadDateTimePicker that is hidden when the page is loaded but if the user selects a specific type of field to search against it then gets shown. When the control gets shown, the buttons for the date and time popups do not show. Weird thing is that if I put a seperate RadDateTimePicker control on the page they do show. This is a control that is hosted on a content page in case that would matter.

<telerik:RadDateTimePicker ID="SearchValueDate" runat="server" Calendar-ShowRowHeaders="false" Visible="false" TabIndex="4" >

</telerik:RadDateTimePicker

if (ddlSearchCriteria.SelectedValue == FilterOperator.DateOnlyRange.ToString()

|| ddlSearchCriteria.SelectedValue == FilterOperator.DateTimeRange.ToString())

{

lblStart.Text = GetString("CustomSearch.lblStart.StartDate.Text");

lblEnd.Text = GetString("CustomSearch.lblEnd.EndDate.Text");

lblStart.Visible = true;

lblEnd.Visible = true;

SearchValueDateEnd.Visible = true;

}

pretty straight forward stuff so I'm not sure where this is broken. Is there anything else I need to do to make this happen?
