Hi,

In a scenario I need not to Collapse the Expanded node even if it has Child nodes. In previous versions it worked by calling an event 'BeforeClientToggle= BeforeClientToggle'

function BeforeClientToggle(node)
{
   if (node.Nodes.length > 0)
   {
      return false;
   }
}

But in Ajax version, this event is not available.

Any suggestion to this query is appreciated.

Thanks,

Tulika

Similarly, if we add other controls within the radgrid,how can we display all the added controls in a messagebox to identify its row indexes?
Thanking you in advance !!

RadGrid horizontal lines not drawing correctly

The horizontal lines in my grid are not drawing properly (for certain columns) when there is grouping and a footer displaying aggregrates. If there is no grouping and footer, the lines appear fine.

The horizontal lines look thin for the length of the column, then return back to normal for other columns so it looks like it's been "shaved" for these columns.

My grid is as follows (and I can attach a screen shot of how my grid looks like). The first column is a checkbox column and I am creating the rest of the columns dynamically.

<telerik:radgrid id="PlanRadGrid" AllowFilteringByColumn="True" AllowSorting="True" AutoGenerateColumns="False" GridLines="Both" HeaderStyle-HorizontalAlign="Center" CommandItemStyle-HorizontalAlign="Left" HorizontalAlign="Justify" OnDataBound="PlanRadGrid_DataBound" OnItemCommand="PlanRadGrid_ItemCommand" runat="server" Skin="WebBlue" OnGroupsChanging="PlanRadGrid_GroupsChanging" OnItemCreated="PlanRadGrid_ItemCreated" GroupHeaderItemStyle-HorizontalAlign="Left" ShowFooter="True" OnPreRender="PlanRadGrid_PreRender" OnItemDataBound="PlanRadGrid_ItemDataBound" OnInit="PlanRadGrid_Init" OnColumnCreating="PlanRadGrid_ColumnCreating" OnNeedDataSource="PlanRadGrid_NeedDataSource" >
     <MasterTableView TableLayout="Fixed" CommandItemDisplay="Top" DataKeyNames="ProjectID" GroupsDefaultExpanded="False"
GroupLoadMode="Client" ShowGroupFooter="True" >
     <CommandItemTemplate>
        <asp:Button Runat="server" ID="ApplyFilterButton" Text="Apply Filtering" CommandName="MultiFilter" />
        <asp:Button Runat="server" ID="ClearAllFiltersLinkButton" Text="Clear All Filters" CommandName="ClearFilters" />
    </CommandItemTemplate>
    <NoRecordsTemplate> There are no projects for this plan version. </NoRecordsTemplate>
    <Columns>
        <telerik:GridTemplateColumn Groupable="False" AllowFiltering="False" UniqueName="CheckboxColumn" Resizable="False">
            <HeaderTemplate>
                <asp:CheckBox ID="headerChkbox" runat="server" OnCheckedChanged="ToggleSelectedState" AutoPostBack="True" />
            </HeaderTemplate>
            <ItemTemplate>
                <asp:CheckBox ID="CheckBox1" runat="server" AutoPostBack="False" />
            </ItemTemplate>
            <HeaderStyle HorizontalAlign="Center" Width="30px" />
                <ItemStyle HorizontalAlign="Center" />
            </telerik:GridTemplateColumn>
    </Columns>
    <ExpandCollapseColumn>
        <HeaderStyle Width="20px" />
    </ExpandCollapseColumn>
     <RowIndicatorColumn>
    <HeaderStyle Width="20px" />
    </RowIndicatorColumn>
    <CommandItemStyle BackColor="Beige" VerticalAlign="Top" Font-Bold="True" Font-Size="Small" HorizontalAlign="Left" />
    </MasterTableView>
    <FooterStyle Font-Bold="True" Font-Size="Small" Font-Italic="True" />
<HeaderStyle HorizontalAlign="Center" />
<GroupHeaderItemStyle HorizontalAlign="Left" />
<CommandItemStyle HorizontalAlign="Left" />
<FilterMenu EnableTheming="True" Skin="WebBlue">
<CollapseAnimation Duration="200" Type="OutQuint" />
</FilterMenu>
</telerik:radgrid>

Thankyou for your assistance,

Resize Window content?

I want to have a RadWindow with a scheduler in it...I'd like the scheduler to keep to the size of the window

Is that even doable? Inside VS the scheduler has the proper size (100%, 100%), but when I load it in the window it's shrunk back down again

[Solved] ajaxRequest + RadWindow + RadDock

We have a particular scenario where we have a MasterPage that contains a RadWindow in the RadWindowManager. When this RadWindow is made visible, certain actions that are made in the RadWindow need to be reflected in the current content page loaded in the MasterPage asyncronously. We are attempting to accomplish this task through various javascript calls.

The goal of our RadWindow is to act as a 'DockCatalog' that contains a listing of the available docks the user can add to the page, and a listing of the current docks already on the page. Through this window, entries in the database are added/removed that represent the docks for the user. The content page loaded into the master page contains all of the loaded current docks for the user.

The following javascript is called from the page in the RadWindow. It's purpose is to call another javascript function to refresh the docks on the content page when the user selects to add or remove a dock item from the page.

    
            // Refresh the docks on the parent page of the radwindows to show the changes  
        
            // the user made from the catalog. 
        
            function RefreshParentPage() 
        
            { 
        
                var rWindow = GetRadWindow(); 
        
                if (rWindow != null) 
        
                    rWindow.BrowserWindow.RefreshDocks(); 
        
            }

The RefreshDocks() function exists on the master page and calls the actual AjaxRequest which will cause Docks to be added or removed from the current page.

    
            // Refresh the docks on the page because the user has  
        
            // added/removed dock customizations from the catalog window. 
        
            function RefreshDocks() 
        
            { 
        
                var ajaxManager = <%= RadAjaxManagerMaster.ClientID %>; 
        
                ajaxManager.AjaxRequest("CatalogItemsInUseChanged");  
        
            }

The handler for this ajax request will reload the docks on the page based on entries in the database for the user. That way the RadWindow catalog can add and remove items to this content page.

Our problem is that we are not sure what AjaxSettings to add to the AjaxManager so that we can see the added/removed Docks without refreshing the page. I know the initiator needs to be the RadAjaxManager, but I am unsure what should be the updated control. Since the AjaxRequest could add or remove docks to and from the current layout, what control should I place as the updated control. I only want it to be ajaxify the process of adding and removing docks from the dock layout.

Below is a snippet of the markup file for the content page that has the docks.

    
            <telerik:RadDockLayout runat="server" ID="RadDockLayout1" OnSaveDockLayout="RadDockLayout1_SaveDockLayout" 
        
                    OnLoadDockLayout="RadDockLayout1_LoadDockLayout"> 
        
                    <telerik:RadSplitter ID="RadSplitter1" runat="server" Width="100%" Height="550px"> 
        
                        <telerik:RadPane ID="RadPane1" runat="server" Scrolling="Y"> 
        
                            <telerik:RadDockZone runat="server" ID="RadDockZone1" BorderStyle="None"> 
        
                            </telerik:RadDockZone> 
        
                        </telerik:RadPane> 
        
                        <telerik:RadSplitBar ID="RadSplitBar1" runat="server" Width="20" Height="100%"></telerik:RadSplitBar> 
        
                        <telerik:RadPane ID="RadPane2" runat="server" Scrolling="Y"> 
        
                            <telerik:RadDockZone BorderStyle="None" ID="RadDockZone2" runat="server"> 
        
                            </telerik:RadDockZone> 
        
                        </telerik:RadPane> 
        
                    </telerik:RadSplitter> 
        
                    <div style="display: none"> 
        
                        <asp:UpdatePanel runat="server" ID="UpdatePanel1"> 
        
                            <Triggers> 
        
                            </Triggers> 
        
                        </asp:UpdatePanel> 
        
                    </div> 
        
                </telerik:RadDockLayout>

Any suggestions? Is there a better way I can add docks from on the fly actions occuring within the RadWindow?
