Above CSS Class is overrided by the below CSS class in RadMenu

Hi,

I got stuck with CSS in RADMenu.

I am having a CSS file for RAD Menu. It is having a lot of CSS class for a single RADMenu.
Its applied fine. I added a new CSS class named '.InnerSubMenu'.
I am applying the css in ".RadMenu1 .rmGroup .rmItem .rmLink .InnerSubMenu". Here, I am changing the font size to 8px. I also mentioned the font size as !important .
But I am having another one css class named ".RadMenu1 .rmGroup .rmItem .rmLink .rmText". Here the font size is 12px.

On examining, i found that the InnerSubMenu css class is applied initially.
But the rmText css class replaces the font size to 12px.

I cant change the rmtext class as it is applied for all nodes in the menu.

The innerSubmenu needs to be applied at particular point of time.

Kindly let me know, how can i achieve the scenario.

Thanks,
Vinoth

GridClientSelectColumn Header Check box Issue

I have a RadGrid with GridClientSelectColumn to select and unselect row(s) client-side. I am using it to select/unselect all the rows using the check box at the header. If the check box in the header is checked, all the check boxes are checked (all rows selected). But the issue is that, even if a single check box (row) is unchecked (unselected) the "Select All" check box in the header is still checked. Is there any way to mark the header check box unchecked in the above case ?
I don't want to use RowSelected/RowDeselected client events to achieve this as it causes performance issues if the grid has many items.
Any immedaite help is appreciated.

RadMenu with RadPanel - Open location changes with change in screen resolution.

Hi Telerik Team,

I am using RadMenu with RadPanelbar like the code below:

    
             <telerik:RadMenu ID="RadMenu1" Skin="" Style="margin-left: 0px; margin-bottom: 0px;  
        
                                                                            margin-top: -1px; margin-right: 0px;" DefaultGroupSettings-OffsetY="2" EnableOverlay="true" 
        
                                                                            DefaultGroupSettings-OffsetX="-30" runat="server" Flow="Vertical" Width="17">  
        
                                                                            <Items> 
        
                                                                                <telerik:RadMenuItem ImageUrl="images/main_menu.gif" Value="0" Width="17">  
        
                                                                                    <Items> 
        
                                                                                        <telerik:RadMenuItem Value="1">  
        
                                                                                            <ItemTemplate> 
        
                                                                                                <telerik:RadPanelBar runat="server" ID="RadPanelBarLeft" ExpandMode="SingleExpandedItem" 
        
                                                                                                    OnClientMouseOver="ExpandItems" EnableEmbeddedSkins="false" Skin="ILPanelSkin" 
        
                                                                                                    Style="width: 197px; height: 500px; background: #e6eaef;" OnItemClick="RadPanelBarLeft_ItemClick">  
        
                                                                                                </telerik:RadPanelBar> 
        
                                                                                            </ItemTemplate> 
        
                                                                                        </telerik:RadMenuItem> 
        
                                                                                    </Items> 
        
                                                                                </telerik:RadMenuItem> 
        
                                                                            </Items> 
        
                                                                        </telerik:RadMenu>

My functionality is to open/close the panel bar on mouseover/mouseout of "main_menu.gif" image.Its working fine. I have set the height of panelbar to 500px, so that it covers whole div on which it opens. Its working fine if there is no vertical scroll bar in your page.But, if vertical scroll bar comes then Radpanelbar goes up from its original position.In otherwords this should open always parallel to "main_menu.gif" image.

Please help me in this regard.

Thanks,

Ankesh Bharti

Toggle filter function

Hello,

We want to implement the following with the RadGrid.

If the user clicks the filter icon, the filter expression 'contains' is being executed. The filter icon changes. A filter icon with an angled red line through is being showed. If the user then click the filter icon the expression 'nofilter' is being executed and the original filter icon gets back.

In fact we want a toggle filter per column.

How can we implement this?

Regards,
Pieter
