Ambiguous use of the word "changed" throughout Telerik documentation

In the Telerik documentation, the word "changed" is used ambiguously which results in a lack of clarity and concision. Here's an example of what I mean. What does the following (hypothetical) sentence mean?

THE ROW HAS CHANGED.

Does it mean that focus has moved to a different row? Or that the row has been modified?

How about the following event name:

RowChanging

Does it mean we are moving to a different row or that the row is undergoing modification?

It is difficult to know which meaning is intended; either meaning can make sense in context. In Windows control programming, we are working with a GUI paradigm where events can be triggered by focus moving elsewhere, but we are also working with an object-oriented paradigm where events are triggered when the underlying data objects undergo modification. So it is very important to have clarity when speaking about "change" as it relates to data-driven GUI controls, where these two paradigms coincide.

Upgrade telerik radcontrols from 2009 version to 2012 Q3

Hi,

I'm currently trying to upgrade a web application that is already using telerik asp.net ajax controls with a 2009 version.

The application is working on IE9 with IE7 compatibility mode activited in the web.config file.

The thing is that when i'm trying to upgrade that version to the 2012 Q3 version for each pages that i'm having RadTabStrip or RadMenu on top of the pages, the following items aren't rendered correctly. When i remove one of the controls my page is rendered correctly after that.

Is there any change with the style stuff since the 2009 version or other thing that I should be looking at that might help?

Also in some case the WebResource.axd is not visible to the apllied style of any following controls (controls after RadMenu and/or RadTabStrip), but after removing the control from the pages all the WebResource style are applying correctly.

Thx for your help,

Guillaume

._selectAllRows does not work in RadWindow with ContentTemplate

I am using a RadGrid w/ GridClientSelectColumn inside a RadWindow w/ ContentTemplate. If I place this RadGrid outside of the RadWindow - the ._selectAllRows event works as expected. But inside the ContentTemplate - it is not finding the reference to the RadGrid - instead throwing this error:

Uncaught TypeError: Cannot call method 'get_element' of null ScriptResource.axd:5723
1. Telerik.Web.UI.RadGrid._selectAllRowsScriptResource.axd:5723
2. onclick

This is the checkbox code that is automatically rendered in the header to allow you to select all:

<input id="wSaveOptions_C_gUnbilledOrders_ctl01_ctl09_ctl01_ClientSelectColumnSelectCheckBox" type="checkbox" name="wSaveOptions$C$gUnbilledOrders$ctl01$ctl09$ctl01$ClientSelectColumnSelectCheckBox" onclick="$find("wSaveOptions_C_gUnbilledOrders")._selectAllRows("wSaveOptions_C_gUnbilledOrders_ctl00", "", event);" />

Oddly, if I write my own routine to deal with it, it works fine:

function selectAll()

{

var masterTable = $find('<%= gUnbilledOrders.ClientID%>').get_masterTableView();

masterTable.selectAllItems();

}

function clearAll()

{

var masterTable = $find('<%= gUnbilledOrders.ClientID%>').get_masterTableView();

masterTable.clearSelectedItems();

}

which is rendered as

function selectAll()

{

var masterTable = $find('wSaveOptions_C_gUnbilledOrders').get_masterTableView();

masterTable.selectAllItems();

}

function clearAll()

{

var masterTable = $find('wSaveOptions_C_gUnbilledOrders').get_masterTableView();

masterTable.clearSelectedItems();

}

Am I doing something wrong? Can I not have a SelectColumn RadGrid in a RadWindow ContentTemplate?

Option to display Select/Deselect All checkbox

I wonder would it be possible when a listveiw is rendered as a list of checkboxes, add an option to display Select/Deselect All checkbox at the top of the list? It could separated by a horizontal line.
E.g.

Select/Deselect All
---------------------
Checkbox 1
Checkbox 2
Checkbox 3
Checkbox 4
...

Multiple cell selection and context menu

Hi!

I have a grid with multiple cell selection enabled - CellSelectionMode="MultiCell".

It works great when I select multiple cells. But when I right click on one of the selected cells to bring up a context menu then all cells will be deselected except the on that I right click.

I want all selected cells to stay selected when I right click on a selected cell. Is it possible to cancel the deselecting in this case?

Thanks
/Mats

Are there still problems using a Required Field Validator with a RadEditor control?

I see a number of posts here and elsewhere about problems with the RadEditor control and the required field validator.

In my current project I have a RadEditor control on both the header and detail template popup of a RadGrid. The RadGrid (and it's code behind) are relatively conventional, derived from Telerik's on-line demos. It appears at present that the required field validator will fire on insert but not when editing an existing record.

Has anyone else had problems like this?
