Hi,

I'm trying to figure out the best way to achieve the following scenario:
1. Have a RadGrid display a table of information i.e.

Customer	# of Orders	# of Products Ordered	Total Revenue
John Doe	10	23	$2300.00

2. When client selects a row, to generate a report ( such as a breakdown of orders) that provides more detailed information on a value (i.e. Customer's name) in selected row.

Thanks,
Yankev

Hierarchical RadGrid Problem

I am trying to display hierarchical data in a RadGrid. I don't know at design-time how many levels deep the hierarchy is, so it seems like I can't use the standard hierarchy option, which requires design of each level up-front. Also, each branch of the hierarchy may not have the same number of levels. It seems like the self-referencing hierarchy is what I want, but when I try to load the leaf-level data into the grid, it takes far too long (for approximately 5800 rows in my test case). I would be willing to work around this via some kind of on-demand loading of the expanded data, but from other posts I have read in the forum, it sounds like the ServerOnDemand option is not supported for self-referencing hierarchies.

Does anyone know of a way to accomplish what I need to do in a RadGrid?

Thanks,
Brian

Timeslot enabled/disabled and navigation

Hi,

I am using the latest Q2 2012 RadControls and finding that if I do the following in the TimeSlotCreated Event

e.TimeSlot.CssClass = "Disabled"

I get the exact result I want and it looks and works great. I see appointments that are in the system, along with white area representing free time slots which can be edited, and the rest is silver/disabled.

However, When performing any navigation commands in the scheduler - DayView, WeekView Timeline or navigate to the next day using the calendar controls, the available, active time slots disappear (see attached screen shots).

I removed AjaxManager and stripped this down as much as I could to see if that was an issue, but it was not. Any thoughts on this greatly appreciated. Thanks!

AlternatingItemStyle and DetailTables

I have a MasterTable which uses DetailTables (in a RadGrid). The MasterTable uses AlternatingItemStyle to color every other row in the grid. The problem is that this color does not come down into the DetailTables (i.e. every other main row is colored, but ALL DetailTables are white/uncolored). I need each DetailTable to match the color/background of its associated row in the grid. Any suggestions?

Display Issue

Below is my javascript I'm using to bring up the context menu when right clicking on a radgrid row.
the Menu.Show(Evt); line causes my whole page to shift down. Keep in mind my ASP page is using a master page, where if I do not use a master page this does not happen. Any Ideas?

function AssignedContextMenu(sender, eventArgs) { alert('a'); var menu = $find(""); alert('b'); var evt = eventArgs.get_domEvent(); alert('c'); var index = eventArgs.get_itemIndexHierarchical(); alert('d'); var vRow = sender.get_masterTableView().get_dataItems()[index]; alert('e'); var vQueueID = sender.get_masterTableView().getCellByColumnUniqueName(sender.get_masterTableView().get_dataItems()[index], "QueueId").innerHTML; alert('f'); if (vQueueID != ' ') { alert('g'); sender.get_masterTableView().selectItem(vRow.get_element(), true); alert('h'); document.getElementById("hidAssignedRowIndex").value = index; alert('i'); menu.show(evt); alert('j'); evt.cancelBubble = true; alert('k'); evt.returnValue = false; alert('l'); if (evt.stopPropagation) { alert('m'); evt.stopPropagation(); alert('n'); evt.preventDefault(); alert('o'); } alert('p'); } alert('q'); }

RadGrid and checkbox preserve

Hi - In a Radgrid, I have a checkbox in HeaderTemplate. When the checkbox is checked, I already set to the Itemtemplate checkboxes selected. Now I need to perserve the selected rows on server-side.

I followed the link - http://www.telerik.com/help/aspnet-ajax/grid-persist-selected-rows-on-sorting.html

That link was working with CommandName and ItemCommand eventhandler. In my requirement,What eventhandler can I go with checkbox id that is in ItemTemplate and loop thru the selected rows in radgrid if the checkbox is selected.

Thanks in advance!

Dropdown Selected Value In Grid Item Created Event

Hello,

I have multiple radGrids on a page and an additional dropdown control outside the RadGrid. I want to display the grids based on the selection in the dropdown. Now in the Grid's item created event, I need to get the dropdown's selected value which I am unable to get as the Item created event is fired before the dropdown's selectedindex changed event. Any help on this is greatly appreciated.

- Sushanth.

RadComboBox VS2010 bug

When using RadCombobBox in an update panel the RadCombobBox freezes and the others control won't make any partial post back.
This happens also with RadAjaxPanel and only in Visual Studio 2010 beta2.
When removing the RadComboBox everything works as expected.

In VS2008 works as expected.

Ex.

IE8 script error when selecting > 800 rows in radlistbox

Hello,

I currently have a radlistbox that is fully populated. The sectionmode is set to Multiple. When I try to select more than 800 rows I get the following error: Stop running this script? A script on this page is causing your web browser to run slowly. If it continues to run, your computer might become unresponsive." in IE8 (works in IE9)

I have two listbox which I'm transferring rows between (which works fine). The issue is with the browser/client trying to highlight/select multiple rows. For testing purposes I set the listbox to AutoPostBack. I noticed "SelectedIndexChanged" get's fired on the first click. Then I Shift-click the last row and I get the above error message before it post back to the server (indicating it's the client side that's failing)

<telerik:RadListBox ID="lbCostCentre" runat="server" Height="550px"

Width="270px" AllowTransfer="True" AllowTransferOnDoubleClick="True"

AutoPostBackOnDelete="True" AutoPostBackOnTransfer="True"

EnableDragAndDrop="True" SelectionMode="Multiple"

TransferToID="lbAssignedCostCentre" AutoPostBack="True"

EnableTheming="False">

<ButtonSettings TransferButtons="Common" ShowTransferAll="False">

</ButtonSettings>

</telerik:RadListBox>
