Load selected image from the Image Gallery into Image Editor

Hi,
the scenario we need is this:
There is a list of images displayed in the gallery view (images are stored on the http file server). After you click on one of the images in the gallery view, we need the image editor to load the selected image for editing, and be able to save it after editing is done.

Do we need to download image first to the local temp folder, or can we load them from the URL? Is there an example?

How can I get image from the selected gallery item loaded into the editor?

Thank you,

ImageEditor

Clear Sorting Icon Vanishes after sorting or filtering.

I am using the Header Context Menu Filter and it is behaving oddly I can't figure this out.

On page load everything looks good but on a postback - just the clear sorting goes away. Any ideas ?

radGrid - How to detecting a user control edit form close event

I have a grid setup with the following settings for the edit/insert form:

            <EditFormSettings EditFormType="WebUserControl" UserControlName="Controls/ucSite.ascx"
                InsertCaption="INSERT" CaptionFormatString="EDIT">
                <PopUpSettings Width="50%" Modal="True" ScrollBars="Vertical" />
            </EditFormSettings>

This is all working fine, but I have my ValidationSummary on my Master page...also working fine. Except, when the user closes the edit/insert window using the window X button the messages in the ValidationSummary don't clear. I found code that should clear it, but I need to do it in an event. I was hoping there would be some sort of ClientEvent to go along with OnPopUpShowing like OnPopUpClosing...there isn't, so it begs the question...what event is there to detect when an edit/insert Popup closes?

The odyssey of the RadGrid and the Dynamically created Columns

So I've come to the conclusion that anytime you use your controls in a manner that is out of the ordinary or the vanilla you might as well save yourself some time and jump off a bridge.

I have a radGrid, that can not be created in the page init or load. The page is setup such that the use fills the grid with columns based on their offload needs. It has a few "canned" columns that are always there. Everything was working fine until I tried to do an Excel offload. The offload "worked" in a sense that the data did exported into a spreadsheet, but the dynamically created columns have no header. I tried to set the column details on the button click...result was data and no header. I moved everything to the NeedDataSource...result was data and no header. I tried resetting the header detail in the ItemCommand right before doing the offload...result was data and no header. Sensing a theme yet? I don't understand why the offload process doesn't operate such that it takes what's actually in the grid and offload it. I'm sure the answer lies somewhere in the murky waters of sorting and paging and having all the data...makes this process no less stressful. I can post my code if need be.

Does anyone have a magic wand they can wave to get me out of this quagmire?

Rad Menu is displayed behind other controls in Edge and Chrome

Hi Team,

We are using Telerik controls for ASP.Net and Rad Menu control in our application to display Menu. It is working fine in IE browser but in Edge and Chrome it is showing behind other controls in the Page. The Div element generated by RadMenu is generated with the option overflow as hidden in these two browsers for rmSlide class.

We tried setting EnableOverLay to true and even increased the z-index of the parent Div element. But those are not working.

Can you please help in resolving the issue.

Thanks in Advance,

Sushma Katneni

How to wait for RadWindow to close in javascript

I have some javascript which do some calculation then open a RadWindow to get some input , after the RadWindow is closed, it will continue the
execution. I know how to use RadWindow's OnClientClosed event. But how can I do it in one javascript function?

aspx:

<telerik:RadWindow ID="rwdPopup" VisibleOnPageLoad="false" Behaviors="Close"
ReloadOnShow="False" Width="900" Height="575" VisibleStatusbar="false" Modal="true"
runat="server">
</telerik:RadWindow>

function func1() {

//do some calculation

var wnd = radopen("Somepage.aspx", "rwdPopup");

//wait for RadWindow close and get the return value from rwdPopup. i.e. var result = args.get_argument();

// do more calculation

}

Updated Telerik Web UI version - breaks

We have a very old ASP.NET web forms website and it was using a 6+ year old version of the Telerik Web UI controls.

In aid of resolving one of our issues where the calendar control "jumps" randomly when creating a new entry, we were advised to upgrade to a newer version of the control (2022.1.302.45).

I installed the Telerik tools and then removed the old references of the control and added the NEW references.

Immediately it breaks the page.

I get the following JS errors when I try to click on the calendar view/grid:
