Skin issue

Hi,
I have been using radcontrols for asp.net for the few years and also started using the new radcontrol for asp.net ajax for the past couple of months. In the earlier version the images of skins was in a directory and if i wanted to change any image i can easily do that just by editing the image. But I’m unable to find the images in the new radcontrol for asp.net Ajax. I even tried altering the images in the skin folder but didn’t work. So can anyone tell me how I can do this or at which location does the image exist? Just to describe what I’m looking for here's an example:
Earlier version radtree vista theme has a black arrow which I didn’t like so what I did I created a blank image of that picture and placed it in the skin folder.
Would be glad if anyone can help.Thanks.

RadTimePicker

Hello. I would like to set the max time for RadTimePicker to be the current time of the day. Meaning, I want to prevent the user from selecting a future time for today. So, if its 9 am currently, I want to grey out/prevent them from selecting 10am, 11 am etc etc for today. Is this possible? I have tried to do this in both client side javascript and server side but cannot get it to grey out the times?

Thanks

q2 problem

I have a tabstrip that i created in the q1 version... there were like 8 page views in a multipage attached to it...

inside each pageview, there is a user control that has an ajax panel with 2 regular panels that are visible and not visible depending on certain criteria...

Everything works fine with the q1...

When i switched to the q2.dll - it stopped working.. the first part of the user control displayed fine, but when i activated a panel by the autopostback from changing the index of a radcombobox on the page... you see the contents of that panel for a second.. and then it disappears.

when i downgraded back to the q1 version... it began working normally again.

to see what I am talking about.. http://uconnectit.com

register as a new user.. and then goto "edit" menu...

then click addnew at the bottom of the grid...

start typing in the combobox... "gm" gmail will autocomplete.. tab out of it to select.. and then you will see the username, password, confirm box come up...

if the q2 version is installed... you SEE the username, password, etc.. but then it disappears..

any suggestions?

the solution i have come up with is to remain using the q1 controls for now. :)

thanks

Jeff

UseStaticHeaders - Header fills grid

Hey folks, I'm hoping someone can tell me why this happens. I already know that the grid freaks out when you use percentages and don't set fixed widths, so I won't even go there, however...

I have a grid Height and width of both the grid and MasterTableView of h:263px, w: 750px...

The grid looks great, even with AllowScroll turned on...

HOWEVER, when I turn on UseStaticHeaders, the grid goes nuts. Some wierd version of the grids header fills the entire grid height and width, with no column header titles visible, just the color of the header. It appears that the grid data is there, but just smashed into an unviewable area at the bottom of the grid.

I've tried all sorts of different settings including TableLayout = Fixed, and Scrollheight, but nothing seems to make a difference. I'd be more comfortable trying to figure this out myself, but no setting I alter seems to have any affect on the problem.

Any help would be appreciated!

Thanks, Kuba

[Solved] When using GridClientSelectColumn is it possible to prevent some rows being selected on a condition?

Hi

When using GridClientSelectColumn is it possible to prevent some rows being selected on a condition?

I tried using the grid client event "OnRowSelecting" with the following function:

function grdSearchResult_RowSelecting(sender, e)
{
    // Check if this row should be selected
    if(e.get_gridDataItem().get_element().cells[SELECT_COL].firstChild.disabled == true)

        e.set_cancel(true);
}

In this particular case I'm checking if the row has the selected checkbox disabled or not.

This doesn't work first time (e.get_gridDataItem() is NULL), however 2nd time onwards it works fine.

Am I taking the right approach?

Kind regards

Mark Eaton

RadTreeView with Context Menus in RadPanelBar producing JavaScript errors

Hello,

We have a problem with RadTreeView with Context Menus running in the PanelBar. Every time menu gets repainted (right mouse click, etc.) we are getting a JavaScript error. The same tree with the same menus running outside the PadPanelBar functions fine. The Context Menus both populated in runtime and static – the same behavior.

Details:

Version: .NET 3.5 ; Telerik ASP.NET controls for 3.5 (2008.1.619.35)

The error is in the code (js):

Telerik.Web.UI.RadMenu._getMaxRootItemWidth=function(_43){

var _44=Telerik.Web.UI.RadMenu._getChildListElement(_43);

var _45=_44.childNodes; ß-this line, 'childNodes' is null or not an object

_43- is a Context Menu element, at the time of the error it is empty, though after you ignore the errors (there can be a number of them ,all the same) the context menu displays just fine.

_44 is null

Some call stack details (not every call stack element, just those seem important)

Called from: var _3e=Telerik.Web.UI.RadMenu._getMaxRootItemWidth(_3d);

Called from: if(this._flow==Telerik.Web.UI.ItemFlow.Vertical){

Telerik.Web.UI.RadMenu._adjustRootItemWidth(this.get_id());

} –tried to set Flow=”Horizontal” in the menu or in the DefaultSettingsGroup- didn’t help

Called from: _7.repaint();

Called from: $telerik.repaintChildren(this); where “this” is a PanelBar – this.element.id= ctl00_ContentPlaceHolder1_rpbNav

Called from: this.get_panelBar()._callRadShow();

Called from:

if (!initialLoad) {

// If this isn't the first page load (i.e. we are doing an async postback), we

// need to re-raise the Application's load event.

Sys.Application.raiseLoad();

}, which is in MicrosoftAjaxWebForms.js

Looks like the conext menu gets interrogated by repaint from RadPanleBar before it gets populated.

Part of .ASPX page (it is a content page within master page):

<telerik:RadPanelItem runat="server" Text="Farm Hierarchy"

Width="100%" Value="FarmHierarchy" Expanded="true" >

<Items>

<telerik:RadPanelItem runat="server" Value="FarmHierarchyBody" >

<cc2:xcPanel ID="pnlFarmTree" runat="server" Width="100%" CssClass="PanelNoBorder" meta:resourcekey="pnlFarmTreeResource1">

<cc2:xcTreeView ID="trMenu" runat="server" CssClass="TreeView" PersistLoadOnDemandNodes="true" Height="400px"

Width="100%" meta:resourcekey="trMenuResource1" onnodeclick="tree_NodeClick" SingleExpandPath="false" OnContextMenuItemClick="tree_ContextClicked" onClientContextMenuShown="ClientContextMenuShown"
