Styles issue while using mozilla firefox

Hi
To improve the perfomance of our webapplication we removed the link to stylesheet in the aspx pages and we have added a seperate project to have the stylesheets. We added a reference to that project and registered the stylesheet references in the style sheet manager in our web (aspx)project. We referred this link http://www.telerik.com/help/aspnet-ajax/radstylesheetmanager.html to do this.

After doing this change everything works fine in Internet Explorer, but we find discrepancies in the styles applied to RADGrid in Mozilla Firefox.
Please let us know the solution.
regards
Bharath

Wrong node info - NodeExpand event

Hello,
I have the following scenario with the Telerik RadControls for ASP.NET Ajax 2009.2.826.20 :
Two panels (P1 (left), P2(right)). In P1 there is a RadTreeView with LoadOnDemand (ServerSideCallback mode). When adding nodes, in the controls collection of the node I have to add a dinamically created table with informations specific for each node. For text I use a Label added in the same collection and node.Value contains the ID of the info. On the client, I am using some functions to remove the table element from each node and display it in the P2 panel. All is good, until I want to expand a node. On the server, in the NodeExpand event handler the Node property of the Telerik.Web.UI.RadTreeNodeEventArgs e argument has a wrong node info. If I have a root node and 5 children nodes and I want to expand the 4th children node, in e.Node I find the text and value of the 2nd node.

Can you tell me what is wrong? Is there any fix for this?

Regards,
Claudiu

Filter with GridCheckBoxColumn not work.

When I try to apply AutoPostBackOnFilter="true" inside GridCheckBoxColumn with Telerik Grid it not filter when I change filter value.

And also I notice that it always include checkbox filter value when I change other column’s filter value.

Ex.

ContactPerson City Country IsMainAddress?

Dharmesh Rajkot India True

Vishal Connecticut USA False

Vimal Baroda India True

(1) AutoPostBackOnFilter not works with GridCheckBoxColumn, here my last column IsMainAddress is GridCheckBoxColumn.

(2) When I try to filter ContactPerson with “Vi” and apply Contains filter it displays only “Vishal, Connecticut, USA, False”

because it added “IsMainAddress?” column’s default fitter value False that should not be.

It should be display “Vishal” and “Vimal” records, this work well other then CheckBoxColumn value. I hope this can be solving

using some differemt method.

Set Checkable to False on Parent Node

Hello,

Is it possible to set the parent node checkable property to false if there are child nodes while the child nodes remain checkable. In other words if a parent has children, the parent is not checkable; otherwise the parent is checkable if it has no children. I have tried to do this under page_prerender after the radtree is databound but with no luck on the syntax. Any help would be greatly appreciated. We are working in .net using vb.

Thanks

NodeCheck on the RadTreeView control not fired

I am trying to use the NodeCheck on the RadTreeView control, version 2009.2.701.20. The Nodecheck does not fire the server side event, I have other events being fired on the server but not the NodeCheck. Here is a code snippet :

<rad:RadTreeView ID="rtvOrganisationStructure" runat="server" ExpandDelay="10" Skin="Office2007"
        AllowNodeEditing="true" DragAndDrop="true" MultipleSelect="true"
        CheckBoxes="true"
        OnNodeEdit="rtvOrganisationStructure_OnNodeEdit"
        OnNodeContextClick="rtvOrganisationStructure_OnNodeContextClick"
        OnNodeDrop="rtvOrganisationStructure_OnNodeDrop"
        OnNodeCheck="rtvOrganisationStructure_OnNodeCheck"
        >
     </rad:RadTreeView>

    
            &lt;rad:RadTreeView ID="rtvOrganisationStructure" runat="server" ExpandDelay="10" Skin="Office2007"<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; AllowNodeEditing="true" DragAndDrop="true" MultipleSelect="true" <br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; CheckBoxes="true"<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; OnNodeEdit="rtvOrganisationStructure_OnNodeEdit"<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; OnNodeContextClick="rtvOrganisationStructure_OnNodeContextClick"<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; OnNodeDrop="rtvOrganisationStructure_OnNodeDrop"<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <b>OnNodeCheck="rtvOrganisationStructure_OnNodeCheck"</b>&gt;<br>&nbsp;&nbsp;&nbsp;&nbsp; &lt;/rad:RadTreeView&gt;

The only event that does not work is the OnNodeCheck. Does the scriptManager need to be on the page? I do not have the scriptManager on the page but all the other events still fire.

I am doing this with c# and asp.net (3.5)

[Solved] Selected cell border in firefox

Hi!

I have a problem with borders for selected cells in RadGrid. Using firefox 3.0.14, if I ctrl-click a cell in the radgrid I get a blue border around the cell (and any subsequent ctrl-clicked cells). Setting the border style of the cell doesn't help as the blue border is on top of the actual cell border. If I use Internet Explorer these borders doesn't show up.

Is there a way of removing this blue border?

The behaviour can be observed in your grid demos aswell, e.g your outlook grid demo:
