Hi

Is it possible to edit the InlineInsertTemplate without losing whats already in it ie the save button etc. I would like to add a drop down to this window but when i add it, it removes all of the buttons and the text area?

Thanks

rsContentScrollArea autoscroll

Hi

I'm currently battling the scroll functionality of the rsContentScrollArea when the scheduler is set to monthview. Some javascript is desiding the height of this element and overflowY is set to scroll. At the same time the javascript makes the element 1px to short wich means that if I set overflowY to auto, there will allways be scroll anyways.

I want the scroll... but only when there is more than 5 rows. Anyone have a suggestion?

Node Templates with Tristate Checkboxes

Hi,

I have a treeview control with 4 levels of branch in it. Each node is rendered as a template and the template has 2 checkboxes.

I need the tristate cascading check mechanism to apply to these templated nodes. Below is some sample code for this based on a simple two branch level tree.

In a nutshell I would like it so that if the user clicks on the first checkbox for the first parent node then the first checkbox in the two child nodes will also be ticked. If one of them is then unticked, the parent first node should show the tristate status.

The purpose of this is to make various admin tasks quick and simple.

Any thoughts?

Regards,

Jon

DocumentManager open with DialogOpener javascript error

Hi all,
i have just updated the controls from version Q3 2008 to version 2009.01.0506.35

When i open DocumentManager with DialogOpener object, a javascript error occurs.

In this snippet i set the DialogDefinitions for the DocumentManagerDialog

    
                        targetFolder = _presenter.GetAttachmentsFolder(); 
        
                        FileManagerDialogParameters dlgManagerParameters = new FileManagerDialogParameters 
        
                                                                               {ViewPaths = new string[1] {targetFolder}}; 
        
                        dlgManagerParameters.UploadPaths = dlgManagerParameters.ViewPaths; 
        
                        dlgManagerParameters.DeletePaths = dlgManagerParameters.ViewPaths; 
        
                        dlgManagerParameters.MaxUploadFileSize = 5000000; 
        
                        // If you don't set the following property, the default value will be used 
        
                        dlgManagerParameters.SearchPatterns = 
        
                            ConfigurationManager.AppSettings["allowedDocumentTypes"].Split(",".ToCharArray()); 
        
                        DialogDefinition docManager = new DialogDefinition(typeof(DocumentManagerDialog), 
        
                                                                           dlgManagerParameters) 
        
                                                          { 
        
                                                              ClientCallbackFunction = "callBackFnAllegato", 
        
                                                              Title = "Gestione documenti", 
        
                                                              Width = Unit.Pixel(694), 
        
                                                              Height = Unit.Pixel(500) 
        
                                                              }; 
        
                        docManager.Parameters["ExternalDialogsPath"] = "~/EditorDialogs"; 
        
                        dlgOpener.DialogDefinitions.Add("DialogDocument", docManager);

Dialog declaration

    
            <telerik:RadDialogOpener runat="server" ID="dlgOpener"> 
        
                    </telerik:RadDialogOpener>

Open dialog

    
            <asp:ImageButton ID="imgAllegatoManager" runat="server" SkinID="btnAttach"  
        
                        OnClientClick="return ShowDialog('DialogDocument');" />

This is the embedded javascript that fails, specifically the first line of the function

    
            _loadLinkProperties : function() 
        
                { 
        
                    var currentLink = this._clientParameters.get_value(); 
        
                    var currentHref = currentLink.getAttribute("href", 2); 
        
                    var anchors = this._clientParameters.documentAnchors;

This is the error:
Error: this._clientParameters.get_value is not a function
Source File: http://localhost:4137/ScriptResource.axd?d=UQWwKN_46q7-uyZ4WTiJtjbw7-TZ21nD4t1jm17a3wzrvCs8Hytb9miequru0VyFY8JL4lX41RPClwykw1ZqHw2&t=ffffffffc54d9c1d

Any suggestions?

[Solved] RadAjaxManagerProxy updating controls inside a FormView gives errors

My page contains a FormView, the FormView only has an insert template. The FormView contains a RadMaskedTextBox Zip, a RadComboBox City, and a RadComboBox State.

Ignoring ajax for a moment, if I click the Insert button in the FormView without any ajax applied to the page the insert happens correctly.

I ajaxify my page with the following code.

    
            <rad:RadAjaxManagerProxy ID="RadAjaxManagerProxy1" runat="server">  
        
                <AjaxSettings>  
        
                    <rad:AjaxSetting AjaxControlID="Zip">  
        
                        <UpdatedControls>                      
        
                            <rad:AjaxUpdatedControl ControlID="City" />  
        
                            <rad:AjaxUpdatedControl ControlID="State" />  
        
                        </UpdatedControls>  
        
                    </rad:AjaxSetting>  
        
                </AjaxSettings>  
        
            </rad:RadAjaxManagerProxy>

The page is set up such that the OnTextChanged event of Zip looks up city and state for that zip and then binds those values to the City combo and selects the given value in the State combo respectively.

The ajaxed Zip lookup works great. My issue begins after I've used the Zip lookup and I click the FormView Insert button. I receive the following error:

Script control 'City' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors(). Parameter name: scriptControl

I've found a number of posts about this issue. None of which seemed to solve my problem. The most illuminating was this one. It gives two solutions "you can update the entire FormView control or you can use RadAjaxManager and set the ajaxsetting for the nested control on Page's PreRender event." I implimented the first approach and it works, but adopting this methodology creates many more issues in our application in other areas. The second solution given is not working for me. When I remove the declarative AjaxSettings described above and insert the following:

    
                    protected void Page_PreRenderComplete(object sender, EventArgs e) 
        
                    { 
        
                        RadMaskedTextBox zip = ApplicationRapidForm.FindControl("Zip") as RadMaskedTextBox; 
        
                        RadComboBox city = ApplicationRapidForm.FindControl("City") as RadComboBox; 
        
                        RadComboBox state = ApplicationRapidForm.FindControl("State") as RadComboBox; 
        
                        RadAjaxManagerProxy1.AjaxSettings.AddAjaxSetting(zip, city); 
        
                        RadAjaxManagerProxy1.AjaxSettings.AddAjaxSetting(zip, state); 
        
                    }

I receive the error "Controls cannot be ajaxified after Page PreRender."

When I try overriding the OnPreRenderComplete event:

    
                    protected override void OnPreRenderComplete(EventArgs e) 
        
                    { 
        
                        RadMaskedTextBox zip = ApplicationRapidForm.FindControl("Zip") as RadMaskedTextBox; 
        
                        RadComboBox city = ApplicationRapidForm.FindControl("City") as RadComboBox; 
        
                        RadComboBox state = ApplicationRapidForm.FindControl("State") as RadComboBox; 
        
                        RadAjaxManagerProxy1.AjaxSettings.AddAjaxSetting(zip, city); 
        
                        RadAjaxManagerProxy1.AjaxSettings.AddAjaxSetting(zip, state); 
        
                        base.OnPreRenderComplete(e); 
        
                    }

I end up with a Javascript error: "Sys.InvalidOperationException: Could not find UpdatePanel with ID 'ctl00_ctl00_ContentPlaceHolder_ApplicationForm_CityPanel'. If it is being updated dynamically then it must be inside another UpdatePanel."

I've tried moving the code to a few other places as well with the same results.

How can I ajax update selective controls that live within a FormView and then successfull save that FormView?

Thanks,

Rob T

Data is not saving when i keep few fields readonly=true and display=false

Hi,

I am trying to insert/update the data in my RadGrid and but could not able to save. I have few fields on the grid and some of them i change the properties readonly=true and display=false. I don't want to see these fields while editing or inserting. When i save the data is not saving. But when i change readonly=false and display=true, the data is saving. I don't know what exactly went wrong.

Temporary i just disable the textboxes while editing/inserting.

Can you tell me what is the reason behind this.

Look at the following one i am disabling the textboxes.

                    Protected Sub RadGrid1_ItemDataBound(ByVal sender As Object, ByVal e As GridItemEventArgs) Handles RadGrid1.ItemDataBound

Application is too slow while rendering

Hi there,

I'm using the latest telerik version. Developed an application using it. If a request is raised from the client side the application takes about 30 to 40 sec to completely display the requested output. I' v about 5 RadGrid One master page 3Radspliters one Tapstrip , Treeview , some RadTextBox and RadComboBox each and every component are of Rad-Telerik component type and RadAjax in one single page.

Even to display the no record found the request and response are about 30 to 40 sec. I could't figure out why it takes this much time.

In my application if the request is raised, with 15 to 20 sec i'm able to see the output . For about 10 to 15 sec the loading ... is happening . After about 30 to 40 sec only i'm able arise another request.

Please suggest me what should i do to increase the performance. I have found some performance tuning articles and tried that too from converting the radcomponents to normal asp controls. But, this does not solve my problem .
