Good morning.

I have a problem with Chrome for Android and RadComboBox in RadGrid.
When I click on the combo nothing happens. Using Chrome dekstop and DevTools to simulate a Nexus 7 I can read this error:

[Intervention] Unable to preventDefault inside passive event listener due to target being treated as passive. See <URL>

https://www.chromestatus.com/features/5093566007214080

The error comes from Telerik.Web.UI.WebResource.axd 

preventDefault @ Telerik.Web.UI.WebRe…289%3aed16cbdc:1133
_cancelEvents @ Telerik.Web.UI.WebRe…289%3aed16cbdc:4652
_compositeDragger @ Telerik.Web.UI.WebRe…289%3aed16cbdc:4604
i @ Telerik.Web.UI.WebRe…289%3aed16cbdc:1133
dispatch @ Telerik.Web.UI.WebRe…289%3aed16cbdc:1133
v.handle @ Telerik.Web.UI.WebRe…289%3aed16cbdc:1133

I use Telerik with 2013.1.417.40 version.

I can solve this problem? In dekstop I do not find this problem.

I am trying to disable cell drag and drop between rows

Here is my grid setup

  <telerik:RadGrid ID="grdResourceGrid" runat="server" 
                            AllowMultiRowEdit="true"  AllowAutomaticUpdates="true" 
                            OnNeedDataSource="OnNeedDataSource"

                            onclick="gridFocus(event)"                            
                            style="margin-top:0px;"

Please help

I am experiencing an issue and I am not sure it is a bug or just is an expected behavior from MS Excel.

I have a Telerik RadGrid, and there is a date column on the grid layout. The date format I am using to display date values is "dd/MM/yyyy". Then, I export that grid data to Excel file with GridExcelExportFormat.Biff type. The problem here is when I open the newly exported Excel file, the date format is changed to "MM/dd/yyyy". I think MS Excel did re-apply the default date format for my date column (?)

I want to keep displaying my date format "dd/MM/yyyy" in the Excel file after exporting the grid data, is there a way to do that?

Here is my code.

Default.aspx

And Default.aspx.vb

Thanks for your support!

Hello,

We have this issue in our developpement on WebForms ASP.NET 4.5.2 (VS2015 Update 3) with last version 2019.2 with this configuration  :

In master.page :

        <script> 
            function RadPan_ItemClicking(sender, eventArgs)
            {
                var oItem = eventArgs.get_item();
                if (oItem.get_expanded()) {
                    oItem.collapse();
                }
                else
                    oItem.expand();
                var sUrl = "";
                var aAttributes = oItem._attributes;
                if (aAttributes.get_count())
                    sUrl = aAttributes.getAttribute("URL");
                if (IsDefined(sUrl)) 
                {
                    if (sUrl!="")
                    {
                        var oPanelBar = oItem.get_panelBar();
                        oPanelBar._postback();
                        eventArgs.set_cancel(false);
                        return;
                    }
                }
                eventArgs.set_cancel(true);
            }
        </script>

<telerik:RadPanelBar runat="server" ID="RadPan" ExpandMode="SingleExpandedItem" PersistStateInCookie="True"
                                    onclientitemclicking="RadPan_ItemClicking"
                                    ViewStateMode="Enabled"> 
                                    <CollapseAnimation Duration="100" Type="None" />
                                    <ExpandAnimation Duration="100" Type="None" />
</telerik:RadPanelBar>

--------------------------

It's a manual binding with 3 level of RadPanelItem, 

We don't use NavigateUrl property but we use OnItemClick event to check data in session before redirect

All RadPanelItems have URL Attribute that is read from OnItemClick  event

The behind Code IS NOT in master page BUT in child Page named BasePage (it's inherit WebPage for all pages of project)

Sample of BasePage.aspx.cs

protected override void OnLoad(EventArgs e)
{

_masterPage = Master as MyMaster;

RadPanelBar oRadPan = _masterPage.FindControl("RadPan") as RadPanelBar;

..... (Manual Binding without datasource)

}

To solve this issue temporarely, we use this Javascript code below BUT it's not clean :

$(function () {

       if (Telerik.Web.Browser.edge) {
            with (window)
                if (!location.href.contains("#") && !location.href.contains("?")) {
                    open(location.href + "?", "_blank");
                    close();
                }
        }
        else {
            if (sPathname.contains("index.aspx"))
                with (window.location)
                    if (!href.contains("#")) {
                        replace(href + "#");
                        reload();
                    }
        }
 });

Hello

We have a requirement to do the following.  Can you please tell me whether it is doable (or how much of it is doable) at the moment using Telerik Diagram.  If it is, can you please point me to a starting point?

So we need to --

- allow user to drag and drop blocks into a canvas

- be able to relate blocks

- have a popup appear when relating two blocks to allow input of one or more attributes

- allow editing of relationship by may be double clicking on the relational lines

- save diagram on a web page

- export diagram to excel

- have an auto-layout button option or allow user to manually move boxes around

- allow user to color code blocks based on some attribute

I did find a page

https://demos.telerik.com/aspnet-ajax/diagram/examples/interactions/defaultcs.aspx

that does some of what we want but not everything.

Any help will be appreciated.

Thank you

Hi,

Is there a way to chose chart culture depending on session value.

Something in Jquery, such as:
