set_virtualItemCount hits database twice

Hi,

I have a grid and paging, filtering enabled. I use client-side databinding and client-side history management. When I run grid, paging and filtering works fine, but when I push browsers back button problem begins.

To see the problem lets look at history.
1 - first load; pageindex = 0, filter = ""
2- push next page button; pageindex = 1, filter =""
3- filter (lets say age column "age < 21"); pageindex = 0 (this is normal, item count changed [27] and pager must be on first page), filter="age < 21"
4- now push back button, pageindex 1, filter ="" read by history control, PageMethods.GetData(dyanmicLinqQuery, sortExpressions.toString(), pageindex, pagesize, updateGrid, webServiceCallFailed) called, and desired data / item count [1152] returns with pageindex=1, and filter="". So I can set mastertableview's pageindex and pager will show "Page 2 of x" which is ture (step 2, pageindex=1). Now updateGrid event fired

    
            function updateGrid(result) { 
        
            tableView.set_dataSource(result.Data); 
        
            tableView.set_virtualItemCount(result.rowCount); 
        
            tableView.dataBind(); 
        
            }

now it comes to line set_virtualItemCount with itemcount of 1152. set_virtualItemCount internally compares previous item count [27] with current one [1152]. If there is a difference then it calls page(0) method and sets pageindex 0 (actually this could be normal for any other scenarios), and this call also fires my RadGrid1_Command which hits datacontext again. And at the end, pageindex=0 (but must be 1 according to step 2), and there is 2 datacontext hits.

So how can I by-pass page(0) event which fired by set_virtualItemCount internally?

Thanks in advance

PS: I am using Q1 2009

[Solved] Client event: OnGroupExpanded issue

Hi, I followed the instruction / tutorial on this page http://www.telerik.com/help/aspnet/grid/ongroupexpanded.html but I am not able to get it work. rowObj.ItemIndex is returning "undefined". Any idea?

This event is fired after a group is expanded and when MasterTableView.GroupLoadMode="client".

Fired by	RadGrid
Arguments	N/A
Can be canceled	No
Examples	ascx/aspx <ClientEvents OnGroupExpanded="GroupExpanded" JavaScript <script> function GroupExpanded(rowObj) { alert("Expanded row with index: " + rowObj.ItemIndex); } </script>

RadAjaxManager removes HTML if statements?

Hello,

On my aspx page I have these styles in the header:

                    <link href="Styles/layout.css" rel="Stylesheet" type="text/css" />         
                     
            <!--[if lte IE 7]>         
                <link href="Styles/ie7.css" media="screen" rel="Stylesheet" type="text/css" />         
            <![endif]-->         
                         
            <!--[if IE 6]>         
                <link href="Styles/ie6.css" media="screen" rel="Stylesheet" type="text/css" />         
            <![endif]-->         
                     

The body background color is supposed to be white, as it is declared in layout.css. In my ie6.css I placed a declaration for "body { background: #000; }" so IE6 would have the black background for testing.

In firefox and Safari, everything is fine until there is an ajax call that adds a html form to the page as its response. In that response, in both firefox and safari and IE7, the black background appears from the IE6 style.

Why after the ajax call is the IE6 if statement being removed, yet when I view the source of the page, the statement is still there, just being ignored?

Poking around with firebug, I see that RadAjaxManager creates some sort of array that holds those three <links> from the page. Does it then write that array back after the ajax is successful? Therefore removing the if statements? What the ajax call loads doesn't contain any css declarations itself, just html web forms.

Multiple combobox's passing parameters

Hi using the example http://demos.telerik.com/aspnet-ajax/combobox/examples/functionality/multiplecomboboxes/defaultcs.aspx I want to extend this to about 10 combbox's where the value of each preceding box is populated based on parameters from all other preceding selections (the example just uses one parameter). This way my 10th box will be populated based on the 9 preceding selections. How would I pass each parameter to the next box?
Any pointers would be great!

Concurrent Production Versions On Server

Is it possible to deploy two Web applications using different Telerik.Web.UI.dll versions?

I'd use 2008-Q3 and 2009-Q1 installed on server GAC.

I'm still migrating to Telerik an application, because an user control doesn't work properly. Meanwhile I'm using RadScriptManager as a workaround, which seems not to work on 2009-Q1.

Bar chart: zero value rows not displaying

I am running a stacked bar chart.
SQL data is returned in the format: Value1, Value2, Date

Any days where value1 and value2 are both zero are not displayed.

Also, if I return more than 10 dates from the query, the chart displays no results at all.

Any suggestions?

Thanks.

Panelbar Bug in 2009/1?

Hi Telerik,
I have a Panelbar in a 100% Height Splitter. ExpandMode="FullExpandedItem" Height="100%".
When I implement a RadAjaxManager, the height of the PanelBar in Firefox "shrinks".

    
               <telerik:RadAjaxManager ID="RadAjaxManager1" runat="server">  
        
                    <AjaxSettings> 
        
                        <telerik:AjaxSetting AjaxControlID="PanelBar">  
        
                            <UpdatedControls> 
        
                                <telerik:AjaxUpdatedControl ControlID="PanelBar" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="litContent" /> 
        
                                <telerik:AjaxUpdatedControl ControlID="litComment" /> 
        
                            </UpdatedControls> 
        
                        </telerik:AjaxSetting> 
        
                    </AjaxSettings> 
        
                </telerik:RadAjaxManager>
