Grid displays differently on dev and production servers

SOLVED. After reinstalling Ajax extensions on the production server it went away.

version 2008.1.619.20

The Radgrid for Ajax is displaying differently on the production and development servers. I read the article relating to javascript errors when streaming the embedded resources, but I'm not getting any javascript errors.

http://www.telerik.com/help/aspnet-ajax/installtroubleshootingproductionserver.html

The development server's grid has a background color different from the form's background color; a border; a highlighted current row. The production server has none of those default visual features.

How do I synch the visual appearance? Have I neglected to copy something to the production server?

Thanks

Timer and UpdatePanel causes full page postback

I'm doing sharepoint development, and we have built a sharepoint page-layout template that contains a RadTabStrip with three tabs. In each of the three page views we have placed a web part zone.

The web part I am building now uses an UpdatePanel and a Timer to regularly refresh data that is being displayed to the user. When I drop this web part onto the default page layout (no TabStrips), the web part behaves perfectly. When I drop that part into any zone on the page that uses a layout with a RadTabStrip, the entire page refreshes whenever the timer ticks.

Here is how I have the tab strip defined in my page layout template:

    
            <div class="standardPadding"> 
        
                        <WebPartPages:WebPartZone ID="ReportTitleWebPartZone" runat="server" Title="loc:Report Title" 
        
                            QuickAdd-GroupNames="Title" QuickAdd-ShowListsAndLibraries="false" FrameType="TitleBarOnly"> 
        
                          <ZoneTemplate> 
        
                          </ZoneTemplate> 
        
                        </WebPartPages:WebPartZone> 
        
                        <telerik:RadTabStrip runat="server" ID="RadTabStrip1" Orientation="HorizontalTop" Skin="CDSC" SelectedIndex="0" MultiPageID="RadMultiPage1" EnableEmbeddedSkins="false"> 
        
                          <Tabs> 
        
                            <telerik:RadTab Text="Gauge"></telerik:RadTab> 
        
                            <telerik:RadTab Text="Bar Chart"></telerik:RadTab> 
        
                            <telerik:RadTab Text="Trend"></telerik:RadTab> 
        
                          </Tabs> 
        
                        </telerik:RadTabStrip> 
        
                        <telerik:RadMultiPage runat="server" ID="RadMultiPage1" SelectedIndex="0"> 
        
                          <telerik:RadPageView runat="server" ID="RadPageView1"> 
        
                            <WebPartPages:WebPartZone ID="WebPartZoneIn1" runat="server" Title="loc:Horizontal Row" 
        
                            QuickAdd-GroupNames="Content" QuickAdd-ShowListsAndLibraries="false" FrameType="TitleBarOnly" /> 
        
                          </telerik:RadPageView> 
        
                          <telerik:RadPageView runat="server" ID="RadPageView2"> 
        
                            <WebPartPages:WebPartZone ID="WebPartZoneIn2" runat="server" Title="loc:Horizontal Row" 
        
                                            QuickAdd-GroupNames="Title" QuickAdd-ShowListsAndLibraries="false" FrameType="TitleBarOnly" /> 
        
                          </telerik:RadPageView> 
        
                          <telerik:RadPageView runat="server" ID="RadPageView3"> 
        
                            <WebPartPages:WebPartZone ID="WebPartZoneIn3" runat="server" Title="loc:Horizontal Row" 
        
                                            QuickAdd-GroupNames="Content" QuickAdd-ShowListsAndLibraries="false" FrameType="TitleBarOnly" /> 
        
                          </telerik:RadPageView> 
        
                        </telerik:RadMultiPage> 
        
                        <WebPartPages:WebPartZone ID="WebPartZone9" runat="server" Title="loc:Horizontal Row" 
        
                            QuickAdd-GroupNames="Footer" QuickAdd-ShowListsAndLibraries="false" FrameType="TitleBarOnly"> 
        
                          <ZoneTemplate> 
        
                          </ZoneTemplate> 
        
                        </WebPartPages:WebPartZone> 
        
                      </div>

And here is a dummy web part that perfectly recreates the issue I'm seeing:

    
                public class DummyWebPart : WebPart 
        
                { 
        
                    protected override void CreateChildControls() 
        
                    { 
        
                        UpdatePanel p = new UpdatePanel(); 
        
                        p.UpdateMode = UpdatePanelUpdateMode.Always; 
        
                        this.Controls.Add(p); 
        
                        Label l = new Label(); 
        
                        l.Text = DateTime.Now.ToString(); 
        
                        p.ContentTemplateContainer.Controls.Add(l); 
        
                        Timer t = new Timer(); 
        
                        t.Enabled = true; 
        
                        t.Interval = 15000; 
        
                        p.ContentTemplateContainer.Controls.Add(t); 
        
                        t.Tick += new EventHandler<EventArgs>(t_Tick); 
        
                    } 
        
                    void t_Tick(object sender, EventArgs e) 
        
                    { 
        
                        // nothing 
        
                    } 
        
                }

Can you give me any suggestions for how to resolve this issue?

[Solved] OnResponseEnd EventArgument has an equal value for all requests

I use RadControls for ASPNET AJAX Q2 2008.
For some purposes I need to process all OnResponseEnd events of RadAjaxManager.
I've sent several ajax requests by client API and OnResponseEnd event raises for all requests immediately and EventArgument in the event handler has an equal value for all requests.

    
            function SendAJAX() { 
        
                var ajaxMgr = $find("<%=radAjaxMgr.ClientID %>"); 
        
                ajaxMgr.ajaxRequest("first$argument"); 
        
                ajaxMgr.ajaxRequest("second$argument"); 
        
            } 
        
            function ResponseEnd(sender, args) { 
        
                alert(args.EventArgument); 
        
            }

    
            <telerik:RadAjaxManager RequestQueueSize="1" runat="server" ID="radAjaxMgr" UpdatePanelsRenderMode="Inline"> 
        
                <ClientEvents OnResponseEnd="ResponseEnd" /> 
        
            </telerik:RadAjaxManager>

So all alerts show "second$argument". Especially if the first request didn't finish yet.
Question is why EventArgument has an equal value for all requests. And why OnResponseEnd raises immediately (not waiting for real response) after calling ajaxMgr.ajaxRequest(...)?

Thank you!

[Solved] RadComboBox refreshes preventing SelectedItem

I have a vb.net 20.0 WebPage.
I'm using Telerik.Web.UI version 2008.3.1314.20

The RadGrid on the page contains a RadComboBox SEE DECLARATIVE CODE BELOW
I click the Add in the CommandItemDisplay, to add a new record. The RadCombo displays the right data.
After I select an item and mouse down on the insert, it resets the RadComboBox. The item I
selected is no longer selected. Anyone know how to correct this for a RadComboBox in an EditItem Template?

Thanx
Steve

[Solved] Grid - Edit mode Styling issues

Hello

I am fiddling with the MasterTableView/EditMode by setting the property to InPlace/EditFormsPopup but I seem to have some styling issues possibly.

When I click "Edit" for a record, the textfields that are generated are very short (enough for around 3 characters). I am not sure if a page stylesheet is causing this, but how can I see the default size of all textboxes or each one individually if possible?

Also, how do I set Update/Cancel to be image icons instead of text if possible please?
Thank you

Cannot get TabStrip Object on the Clientside

Hi,
I have got an radtabstrip in combination with radpageview on my page. I got 2 tabs and 2 pageviews. Now I am trying to disable one of the two tabs on the clientside. But I don't get the real clientside Object and so cannot call the findTab ... functions.
I always get an object of the type: DispHTMLDivElement.

What I am doing wrong?

Q1 2009 +firefox2 bug?

Hi,

I decided to do some regression testing on a Linux box that has firefox 2.0.0.17 loaded. It seems all my toolbars are stretched across the page and the text is all left align on top of each other. Of course firefox3 has no problems. I verified the issue by going the demo site and observed the same issue with your markup.

I'm not sure what browser version's Telerik supports... just thought I would give you guys a heads up on a potiential problem.

Thanks,
Bruce

Installing Live Demos

Hello.

Just ran the EXE to install the live demos locally and it yellow screens on inner pages due to not finding a DB. I guess I assumed that the files in the local AppData installation directory would have been sufficient, but perhaps I should have first installed SQL Server Express?

If so, and I install SSE now (after the Telerik package is installed) would I need to run some scripst?

Thanks.

Set the Rad splitter height and width on window resize

Hi,

I wrote a small script to set the height and width of splitter on window resize. I am getting an script error saying that object doesn't support this property or method. Please help me to set the desired height and width for the splitter. Below is the script.

    
            <script type="text/javascript">   
        
                window.onresize=resized;  
        
                function resized()  
        
                {  
        
                    var splitter = document.getElementById("ctl00_ReportContent_Splitter1").id;  
        
                    splitter.set_height(document.getElementById("ctl00_ReportContent_ReportRow").clientHeight);  
        
                    splitter.set_width(document.getElementById("ctl00_ReportContent_ReportRow").clientWidth);  
        
                }  
        
             </script>

I even tried spliiter.resize(). This also gave JS error. I referred the splitter's ClientSide API from http://www.telerik.com/help/aspnet-ajax/splitter_clientsideradsplitter.html.

Thanks,
Nataraj
