Hi

Where is/when can we get the same new feature MultiColumnComboBox as for example .Net Core?

Is there a way to fire the ItemCommand event from javascript the same as it would coming from a telerik control within a template item?  Using a telerik checkbox or other control inside a template, I can set the command name and argument.  When the server side itemcommand event fires, the event args parameter will have the command name, command argument, as well as the correct data item.

I have an ASP checkbox that calls a javascript function to do some validation.  I then call the mastertable.fireCommand  function, which triggers the server side itemcommand event.  I'm able to pass the command and argument, but the data item in the event args is always index zero.  I've found a way to retrieve the index of the data item on the client, and pass that index as the commandargument.  But I'd like to be able to use the commandargument parameter for something else.  

            function CheckClick(sender, Idx) {
                debugger;
                var masterTable = $find("<%= rgGrid.ClientID %>").get_masterTableView();
                var row = masterTable.get_dataItems()[Idx];
                masterTable.fireCommand("Post", Idx);
            }

I could combine the index and additional data and send it together in the command argument, so I do have a workaround.  But since the telerik controls are able to pass all three, I assume there should be a better way.  I expected something like a fireCommand function of the data item, but I'm not finding anything.  How do the telerik controls do that?

Hi,

Not sure where to post this since I'm using several Telerik control on my page and not sure which one is causing the refresh issue below.

Basically, my WebControl contains a RadAjaxmanagerProxy, a RadSplitter with 2 panes, 1 RadTreeView and some other basic controls such as buttons, labels etc ...

What I have designed is a page that displays a list of platforms (Web / Windows / Android / IOS) all of which are html clickable tags handled with JS. When clicking on one of them, the RadTreeView is refreshed to display a tree of folders and documents.... same as a very basic file explorer except everything is stored in DB.

This scenario works perfectly fine but I experienced some refreshing issue that I was able to solve in a very weird way, hence why I'm actually wondering if this wouldn't be a bug or something.

Here's the code of my webControl code below:

Now, initially, the Visible property of the last control in this code (RbtSetPlatform) was set to False, since this is called by my JS __doPostBack('<%= RbtSetPlatform.UniqueID %>', platformId); Line 149

When that RadButton was displayed on the page, the RadAjaxManager was doing its job perfectly fine, but as soon as you set it to Visible=false the whole control was reloading.

I had to fix this by adding a class to my RadButton and set the display property to none.

What am I missing here to explain this behavior ?

Cheers,

Hi,

We are using Telerik RadGrid in our WEB application and its version is 2016.1.225.45.

When we are setting the page size to 1000, it will throw an error when click on each page.After this error occurred no other functionality works as earlier.we need to refresh the entire page in order to works as earlier .

It is working fine up to page size 650. 

Herewith attaching the screen shot of script error occurred when page index change event fires.

Can you please provide a solution for this error ?

I have a RadGrid with Batch EditMode wherein I have two RadCombobox 'ProdID' and 'ProdDescription' .

On the click of Add New Button in GridDropDownColumn which is Combobox which populates the first Comobox(ProdID).On the IndexChange of ProdID I need to grab the selected value and query upon database to fetch the values of second RadCombox(Prod Description)

Please tell me how to achieve this with code sample

I have a need for my image to be 100% width of the screen, and the height auto adjust based on the width.

I've got it working as desired using the below, the image height adjust with the width for different window sizes.
But, the animations don't work, the image simply disappears.  If I don't have the .rigItemBox class as shown below, the animations do work, but the image doesn't resize as desired.

Any Suggestions?

<form id="form1" runat="server">
           <style type="text/css">
            html, body, form {
             margin: 0px !important;
        }
            /*Resize of the Image works as desired when the browser window is resized, but it breaks Animations, the image disappears*/
        .rigItemBox {
            height: 100% !important;
            width: 100% !important;
        }
        .RadImageGallery {
            background-color: transparent !important;
        }
        .rigToolbar {
            display: none;
        }       
        .rigActiveImage img {
             padding: 0px !important;
             width: 100% !important;
        }
               
        </style>
         <script type="text/javascript"> // Auto start the main carousel/slideshow
            function pageLoad() {
                $find('<%=RadImageGallery1.ClientID%>').playSlideshow();
            }
        </script>
        <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
        </telerik:RadScriptManager>
        <div>A div with some text above our Image Gallery</div>
         <telerik:RadImageGallery ID="RadImageGallery1" runat="server" LoopItems="True"  Width="100%"
            ToolTip="Click to View All Featured Products/Projects" AppendDataBoundItems="True" ImagesFolderPath="~/Images/Projects/">
            <ThumbnailsAreaSettings Mode="ImageSlider" />
            <ImageAreaSettings Width="100%" ResizeMode="Fit" ShowDescriptionBox="false" />
            <ToolbarSettings Position="None" />
            <ClientSettings>                              
                <AnimationSettings SlideshowSlideDuration="3000">
                    <NextImagesAnimation Speed="1500" Type="Fade" />
                    <PrevImagesAnimation Speed="1500" Type="Fade" />
                </AnimationSettings>
            </ClientSettings>
        </telerik:RadImageGallery>
        <div>A div with some text below our Image Gallery</div>       
    </form>

I have a radgrid with an ASCX in edit mode I cancel the default operation, to pass some initial values to the control. But the ASCX appears in the first fial as if it were in insert.
