Hi

Re: http://www.telerik.com/forums/value-cannot-be-null-parameter-name-key-exception-is-thrown-after-q2-2015-release

I use page inspector as the default "Browse with" feature.
This error was also showing up if IE or Firefox was selected. 

What is the expected release date for SP1 for Q2 2015 asp.net ajax tools mentioned in the link above?

Thanks

Is there a way to do this?

I am looking at this example but it doesn't have paging.

http://demos.telerik.com/aspnet-ajax/grid/examples/functionality/selecting/row-selection/defaultcs.aspx

When I go to the next page, no items are selected.

<DetailTables>
                                                    <telerik:GridTableView  width="100%" runat="server" AutoGenerateColumns="false">
                                                        <ParentTableRelation>
                                                            <telerik:GridRelationFields ></telerik:GridRelationFields>

                                                        </ParentTableRelation>
                                                        <Columns>

.......</DetailTables>

 Hi when i try scrolling horizontally  both the parent and child grid columns scroll but i have more columns in child than in parent so scrolling ends with the parent and i still have child columns which are invisible

I downloaded the Q2 2015 version of Telerik asp.net controls and my question:

Is fill gradient enabled on RadDiagram control? 

I assume this feature is enabled because I see the next sample on Kendo Diagram and gradient is enabled:

Please tell me If gradient is enabled on RadDiagram asp.net control.

Thanks 

I am trying to access div tags within DataGroupTemplate from ItemDataBound but nothing is coming up for me. Not sure what i'm missing or might I be taking the wrong approach here?

Hi all,

I m trying to make an multi file upload by using RadAsyncUpload.
Project is working well on local but when i publish it, control does not include any uploaded file, so it does not enter the for loop and a exclamation mark  appaers.

<telerik:RadAsyncUpload ID="RadAsyncUpload1" runat="server" TargetFolder="~\AttachPath"
                        TemporaryFolder="~\App_Data\RadUploadTemp" AllowedFileExtensions="jpg,jpeg,png,gif">
                        </telerik:RadAsyncUpload>

 protected void lnkara_Click(object sender, EventArgs e)
        {
            PopulateUploadedFilesList();

            ConfigDataContext data = new ConfigDataContext();
            if (!string.IsNullOrEmpty(dropfleet.SelectedValue))
            {
                for (int i = 0; i < RadAsyncUpload1.UploadedFiles.Count; i++)
                {
                    CNF_FILE_PATH newfile = new CNF_FILE_PATH();
                    string path = ConfigurationManager.AppSettings["filePatch"] ;
                    newfile.FILE_PATH = path + RadAsyncUpload1.UploadedFiles[i].FileName;
                    newfile.REGISTRATION = dropfleetlist.SelectedItem.Text;
                    newfile.FLEET_ID = dropfleet.SelectedValue.ToInt();
                    data.CNF_FILE_PATHs.InsertOnSubmit(newfile);
                    data.SubmitChanges();
                    sucsessful.Visible = true;
                }
              
            }
        }

I have been trying to get the "RadProgressArea" control to work reliably.  I have a process that allows the end user to build a list of reports to process, set a ton of options, then press a magic "go" button and generate all the requested documents.  Everything actually works with the exception of the progress display.

 The progress display currently is a "RadProgressArea" control configured along the lines documented elsewhere in the demo's covering "Custom Progress" configurations.  I have a RadProgressManager and RadProgressArea controls on a standard master/client page website.  The event process is fired off via a toolbar button being clicked in the header template of a RadGrid.  The site is your standard C# 4.5 framework type website built using the Telerik suite of products including the Telerik Reports.  Based upon my research I have a properly configured web.config file.  My trust levels are set to Full so it is not a question of Reflection not being available.

 My problem boils down to the process works some of the time.  That is to say the Progress Area pops up and displays the data without error.  The user is able to press the cancel button and everything works.  Notice I said some of the time?  Using the same hardware/software/selected options, the same process will not display the RadProgressArea control the next time (of course it isn't a every other time problem).  This doesn't mean the process doesn't work, simply that the user display doesn't show the progress of the update and no option of canceling is given.   In my particular case all the required reports get built so the end result is a happy user however they want their cancel button.

I have even gone so far as to forcibly show the progress area via client side code.  While this does work, when it "fails", the shown progress area mysteriously "goes away" or is ghosted preventing user interaction with it.  When it works it works irrespective to being forcibly shown.

 Does anyone have any suggestions on paths to explore to solve my problems?  Have I somehow reached a technical limit that I did not know of?  Should I be looking toward some kind of Asynchronous web service of such?  My goal is simply o give my users a progress display and the ability to cancel the task (subject to browser compatibility of course) in a reliable manner.

Hi

I use the RadPersistenceManagerProxy because I use MasterPages. All works fine!

Because I need to persist the RadDateTimePicker, which is not supported, I want to save it manually with the OnSaveCustomSettings function. How can I use this approach in child page will mean with the RadPersistenceManagerProxy?

Regards
