I am trying to achieve a similar experience as in your CardView demo with the cities. The images are stored as block blobs in an Azure storage account. The blobs have tags, which i want to expose , similar to the meta from the demo where we have city name, population, country).

As far as i saw, there is no direct integration for CloudBlockBlob, so i am trying to place this in a byte array in order to display. Yet the outcome is an empty box in the grid, for each item from the container. the blobs are correctly downloaded, verified by writing the fileContent byte array to disk via filestream.

Any idea on how to achieve this?

Thank you!

Hi, 

Can I load pictures via LoadImageFromUrl from a local disk without async methods?

The code below works, but it works poorly and often the images do not load, or not all are loaded.

Uri uri = new Uri(Path.Combine(Holder.TempPath, e.Url), UriKind.Absolute);

WebClient client = new WebClient();
client.OpenReadCompleted += (w, a) =>
    {
     if(a.Error == null)
      {
    try
     {
             e.ImageElement.Init(a.Result, new Telerik.WinControls.RichTextEditor.UI.Size(16, 16), extension);
     }
      catch
     {
       //Handle errors
      }
    }
    };
    client.OpenReadAsync(uri);

Hi,

i would like to change cursor for data field label in RadDataLayout, to make it work as hyperlink, I set it font as below, but can't find any cursor property, is it possible?

Private Sub RadDataLayout1_ItemInitialized(sender As Object, e As Telerik.WinControls.UI.DataLayoutItemInitializedEventArgs)

            Dim ci As DataLayoutControlItem = e.Item
            e.Item.Font = New System.Drawing.Font(e.Item.Font.Name, e.Item.Font.Size, FontStyle.Underline)

end sub

Thanks

Hi,

When the record count is more than 500, the loading time of the appointments on the scheduler, loading time of the unassigned calls & drag & drop the assigned calls on the scheduler is taking more time to load, as we have used for loop function for binding the records.

To reduce the time taken we have used parellel.for threading concept but this is not applicable for the below functions.

=> scheduler.Appointments.Add(appointment)
=> scheduler.PerformLayout()
=> scheduler.Refresh()

It is a big problem for us, Can you please suggest if there a concept/method to reduce the loading time in the radscheduler? 

Video link mentioned below for your reference.

Hi,

Can I set hover style for link in html?

it's style not working:

a:hover {
            color: #3ca9f6
        }

     Hi, I've been researching and trying to understand the custom filtering, but can't seem to understand it. I currently have a gridview with 5 columns.  I plan to have 4 text box and 1 dropdown that I want to use to filter the gridview.   I have tried the custom filtering from (https://www.telerik.com/videos/winforms/filtering-and-expressions-in-radgridview-for-winforms) but this is more on the style and doesn't hide the non-filtered rows.  I have tried to understand the custom filtering row in Demo application >> GridView >> Filtering >> Custom Filtering Row however, this is a bit too complicated with the usercontrols...  I've attached what my page looks like...  I can't seem to get the filtering on this page correct.  Can someone help?
