Hi, Telerik.
I´m using radcontrols for asp.net ajax and everything was working with version 1 of Chrome.
Now I installed version Chrome 2 and my toolbar dissapeared, is not visible. What happened?!
This is the code for the toolbar:

 

<telerik:RadToolBar ID="radtbMenu" runat="server"

 

 

CausesValidation="False" Skin="Outlook" OnClientButtonClicked="GUIToolBarOnClientButtonClicked">

 

 

<Items>

 

 

 

 

<telerik:RadToolBarButton runat="server" Value="Buscar" CommandName="Buscar" ToolTip="Buscar" />

 

 

<telerik:RadToolBarButton runat="server" Value="QuitarFiltro" CommandName="QuitarFiltro" ToolTip="Quitar Filtro" AllowSelfUnCheck="true" CheckOnClick="true" />

 

 

<telerik:RadToolBarButton IsSeparator="true"></telerik:RadToolBarButton>

 

 

<telerik:RadToolBarButton runat="server" Value="ExportarExcel" NavigateUrl="exportar.aspx?rw=1&tip=1&pag=Gastos" Target="_blank" ToolTip="Exportar a Excel" />

 

 

<telerik:RadToolBarButton runat="server" Value="ExportarPDF" NavigateUrl="exportar.aspx?rw=1&tip=2&pag=Gastos" Target="_blank" ToolTip="Exportar a PDF" />

 

 

<telerik:RadToolBarButton IsSeparator="true"></telerik:RadToolBarButton>

 

 

<telerik:RadToolBarButton runat="server" Value="Actualizar" CommandName="Actualizar" ToolTip="Actualizar" />

 

 

 

<telerik:RadToolBarButton IsSeparator="true"></telerik:RadToolBarButton>

 

 

</Items>

 

 

</telerik:RadToolBar>

 

I set the image for the toolbarbuttons using:

radtbMenu.FindItemByValue(

"Buscar").ImageUrl = CUtil.URLImagen(this.Page, "iconos.menfiltrar.gif");

 

radtbMenu.FindItemByValue(

"QuitarFiltro").ImageUrl = CUtil.URLImagen(this.Page, "iconos.menquitarfiltro.gif");

 

radtbMenu.FindItemByValue(

"ExportarExcel").ImageUrl = CUtil.URLImagen(this.Page, "iconos.menexportarexcel.gif");

 

radtbMenu.FindItemByValue(

"ExportarPDF").ImageUrl = CUtil.URLImagen(this.Page, "iconos.menexportarpdf.gif");

 

radtbMenu.FindItemByValue(

"Actualizar").ImageUrl = CUtil.URLImagen(this.Page, "iconos.menactualizar.gif");

 

Can you help me, please?
thanks a lot,
Daniel.

Hi,

I am using the RadScheduler, and would like to sync it with Exchange; however, I can't seem to find the ExchangeSchedulerProvider  class anywhere.

Please advise.

Hi,

I don't know if it is a known bug, or a normal behavior, but...

On this page : http://demos.telerik.com/aspnet-ajax/window/examples/restrictionzone/defaultcs.aspx

Just drag the top border of one windows under its bottom... Window height will remaing to a minimum value, but will start to move... Until it exists restriction zone...

Only one pixel remains stuck in zone.

Same behavior for width...

Hi,

I want to give users an easy way to create new appointments, instead of searching through shceduler weeks.

Here is what I am thinking about :

I have a DataSource that accourding to appointment duration, available time slots (like working hours) and existing appointments, can give me free time areas where the new appointment can be placed without overlapping existing ones.

I want to do is showing them a sort of datetime slider where user can drag the new appointment to the place they want, like a slider.
Visible date range can be set, and working hours (for each day) too.

The dragging element can be templated (for custom text and color), with size according to new appointment duration.

Moving new appointment into a slot with more available time than the appointment duration (like a 20min appointment sliding in a 1h slot) can be snapped to a customizable number of minutes (ex: for 5min, dragging appointment can make it start at +0min, next step is at +5min, +10min etc...)

Slider rail can be templated (at least to see if areas are available or not) to show different type of available time slots.

Today, I know that none of your controls can achieve this, if I want a control with this behavior, I have to make it myself.

Do you think that your team could make a control like this ? Or if you have a idea of how I can create my control...

Thanks

I've seen one or two recent posts on this error, but no resolution.

I am using 2009 Q1 controls. Here is how I generate this error on my system here at work. I create a new Ajax-enabled web application. I make sure that the folder holding the site is designated as an application. I drag RadAjaxManager into the default page. I compile and bring up the page (on localhost) -- the javascript error "sys.webforms.pagerequestmanager is null or not an object" appears. (In more complex solutions, I have seen that this error prevents functioning of components like RadEditor.) It is entirely related to RadAjaxManager.

Now, I should mention that my computer at home, running the same application, does not have this error. So there is clearly something relating to my installation causing this, but it seems to be bothering other people as well. I have not been able to identify what the issue could be, it isn't anything obvious. What it means is that I do not have a way to develop Ajax-enabled sites using Telerik controls while at work. Which is not good.

Hi,

We downloaded the evaluation version of RadControls for ASP.Net and are using the RadTreeView. We are planning to purchase the full version soon, but we ran into a strange issue with the RadTreeView control.

Our TreeView control needs each node to be template as a Table. But each level of the tree needs a different template, so not one single template for the whole tree. Also, all nodes are created dynamically at runtime, and the SingleExpandPath property is set to true.

Now we experience the following issue:

When we select the second node below a templated node, the nodeValue we get at serverside is the value of the first node!

I was able to reproduce this with a simpler version of the code we use for real, when you run the code below, you can expand the tree until the second level, and then, when you select the “child2ofchild1” node, the code behind will tell you that “child1ofchild1” nodes was selected. Could you guys look into this and tell us what we are doing wrong?

 

The asp.net code:

 

<telerik:RadScriptManager ID="RadScriptManager1" Runat="server">
</telerik:RadScriptManager>

<asp:UpdatePanel ID="UpdatePanel1" ChildrenAsTriggers="true" runat="server">
<ContentTemplate>
 <telerik:RadTreeView ID="RadTreeView1" Runat="server" SingleExpandPath="true"
  OnNodeExpand="TreeView_NodeExpand" OnNodeCollapse="TreeView_NodeCollapse"
  OnNodeClick="TreeView_NodeClick">
 </telerik:RadTreeView>
</ContentTemplate>
</asp:UpdatePanel>

I want to get new values from a database every 30 seconds. I've setup an ajax panel and put a timer in it. It fires every 30 seconds and updates labels on my aspx page.

Now i want to move images on the page based on the new database values. I aim to do this using DIV tags and by setting the left and top properties. For this i need the values from the server side.

How do i send values from the server to client?

Kind regards
Andrew

Hi,  I have seen accordians like this that fully expand (and therefore show all child options) if javascript is disabled on pageload.

e.g. http://www.projectseven.com/viewer/index.asp?demo=apm

Is this possible or is there a workaround with the telerik panelbar? I have someone asking if this can be done...

Thanks,
Matt

I have a rad panel inside a master page. Its EnableEmbeddedSkins & EnableEmbeddedBaseStylesheet is set to false. It works fine.
But I have one content page which has another rad panel. Its skin is set. When this content page is called the skin of the rad panel inside the master is also changed.
plz help.
