Custom Response.Write on Session Timeout

Hi,

My web app uses several radWindows that return a parameter to the parent window via a callback JS function. These work fine, but I'd like to improve the current behavior with error trapping code that can close the form before the entire ASPX page is sent to the browser.

In the ASPX pages displayed by the radWindow, I'd like to start trapping for session time-out and other conditions within the page_load event. To optimize performace, I'd like to use Response.Write (or Response.WriteFile) to send a custom response (simple HTML form + JS) to the browser that gracefully closes the window, bypassing the load of ASPX page content. This approach will be much faster than injecting JS into the ASPX page via RegisterStartupScript (or similar method) that invovles the normal ASPX page lifecycle.

But in order to write a custom response to the browser, I need to ensure the response page includes the necessary Telerik JS libraries that let me (a) close the radWindow and (b) return a value to the parent page.

Can you tell me how to do this? Are there a set of core Telerik JS libraries that I need to include? Ideally, I can continue using JS functions such as GetRadWindow() in order to close the form, such as:

var currentWindow = GetRadWindow();

currentWindow.argument = arg;

currentWindow.close();

Thanks.

Rows drag'n drop: items being dragged are enclosed in an unfitted square

Hi.

I'd like to have my items being dragged (not yet dropped) to be enclosed in a fitted "square" like it does in the demo. My version have thoses items in a black bordered white square with a height fixed for about 8 rows so that if I drag just one item, I see a white area under my dragged item of about 7 rows height. Dragging between 1 and 8 items doesn't change this box height. Dragging more than 8 rows is OK. Also sometimes the width is not well fitted (as in the demo, there is a small withe area at the right of the items) but I can live with that.

Also, how can I get the little dotted line that shows where the dragged items are gonna be dropped?

Chart frustration

I am trying to put together what I consider is a very simple chart. I have a SQL data source setup that returns 15 rows of 4 columns. Column 1-3 are numeric values, column 4 is a text string. I want a simple bar chart with col1 plotted against the left Y axis and col2 and col3 plotted against the right Y axis. The X axis should be the labels in col4. In 3 hours of playing with a RADChart I have been unable to accomplish this. I've been thru the Trainer video and tried to figure out what is what in the RADChart pdf.

What I have gotten is the chart shrinking down to a 14X16 pixel box. After a resize of the chart the center plot area says there is no or an empty series. I've tried autosize and manually entering entering labels on the X axis and all I ever get is 7 labels. Is there anyone who can give me a simple walkthrough of how to accomplish this?

Thanks,

JB

Controls losing Skins

Hello,

i have a multiview with 2 views and a radgrid in each view on an aspx page. The radgrid in the first view loses the skin in the following circumstances:

switching the multiview to the second view
pressing a button in the second view which opens a child window via onclick event and window.open()
closing the childwindow (the onunload event of the childwindow does the following: window.opener.document.forms(0).submit())
the childwindow is closed and the page is refreshed
the the radgrid in view two has its normal appearance
switching to view one via a button shows me a ragrid and radcomboboxes without skins (i'am using only the embbeded skins)

What should i do? I tried the radstylesheetmanger but the same happens.

can focus be set? and after callback?

hello,

i have two RadComboBoxes on my page: CarMake, CarModel. when the user selects a CarMake, it initiates a callback via an RadAjaxManager and updates the list collection on CarModel via code-behind.

this works.

however, a problem -- my users use a keyboard and need to tab from one item to the next. currently after the callback completes and the second RadComboBox is bound, the focus is lost..it defaults to the top of the page. no good. ive tried setting the focus in my callback code-behind, but it does nothing.

1) how can i set the focus after an ajax databind?

2) is this how i should be doing the ajax-goodness? or should it use client-side events & handlers?

my ASPX

    
            <Telerik:RadAjaxManager ID="RadAjaxManager1" runat="server"> 
        
                <AjaxSettings> 
        
                    <%-- Make updates Model --%> 
        
                    <Telerik:AjaxSetting AjaxControlID="rcbVehicleMake"> 
        
                        <UpdatedControls> 
        
                            <Telerik:AjaxUpdatedControl ControlID="rcbVehicleModel" /> 
        
                        </UpdatedControls> 
        
                    </Telerik:AjaxSetting> 
        
                </AjaxSettings> 
        
            </Telerik:RadAjaxManager> 
        
            <span class="formLabel">Make:</span><br /> 
        
            <!-- by setting AutoPostBack=true, and using the AjaxManager, we can make this auto-update the Model list --> 
        
            <Telerik:RadComboBox ID="rcbVehicleMake" DataValueField="MakeCode" DataTextField="Description" Width="150" DropDownWidth="200" ShowToggleImage="false" AllowCustomText="False" MarkFirstMatch="true" OnSelectedIndexChanged="rcbVehicleMake_SelectedIndexChanged" AutoPostBack="true" runat="server"/> 
        
            <br/><br/> 
        
            <span class="formLabel">Model:</span><br /> 
        
            <Telerik:RadComboBox ID="rcbVehicleModel" DataValueField="ModelID" DataTextField="Description" Width="80" DropDownWidth="125" ShowToggleImage="false" AllowCustomText="False" MarkFirstMatch="true" runat="server" />

code-behind

    
            protected void rcbVehicleMake_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e) 
        
            { 
        
                SetVehicleModel(); 
        
            } 
        
            private void SetVehicleModel() 
        
            { 
        
                //clear old values 
        
                rcbVehicleModel.Items.Clear(); 
        
                rcbVehicleModel.Text = string.Empty; 
        
                string make = rcbVehicleMake.SelectedValue; 
        
                if (Strings.Exists(make)) 
        
                { 
        
                    rcbVehicleModel.DataSource = Lookups.GetVehicleModelsByMake(make); 
        
                    rcbVehicleModel.DataBind(); 
        
                    rcbVehicleModel.Items.Insert(0, new RadComboBoxItem()); 
        
                    //trying to set the focus..not working 
        
                    rcbVehicleModel.Focus(); 
        
                    Page.SetFocus(rcbVehicleModel); 
        
                } 
        
            }

Radeditor Tools not showing up like was is presented on site

I have installed the radeditor version 5.4 but have noticed I'm not getting all the tool set that appears on Teleriks page. Why might that be? My tool set doesn't look that different then the out of the box sharepoint tool set. This link shows telerik's radeditor tool having flash, media player, letter strike through, full justification, print, and others. It just seems we are missing something. Are there two versions like an ASP.Net and AJAX version or a full featured version? This is what Telerik shows on their web site. Link
