Hi guys,

Has anyone successfully applied third party theme to RadGridView? How much effort involved ? This is our predicament: we really like Telerik controls especially the RadGridView but Business is kinda worried about its look being very different from the rest of non-Telerik controls. The option of migrating everythiing to Telerik controls is just not practical at this point because of schedule contraint.

So, if someone has attempted the feat we're planning, could you please provide us ideas and starting point?

Thanks
Gio

Hi Admin,

I did some search in this forum and it seemed that no similar topic has been post.

I have an ObservableCollection<AbstractEntity> which contains some derived class instances such as CustomerEntity and EmployeeEntity. Binding this collection to a RadGridView ItemsSource is ok. Data is displayed correctly.

I want to apply some filters, such as showing CustomerEntity or EmployeeEntity only. So I defined a ListCollectionView like this:


then bind the RadGridView ItemsSource to this ListCollectionView, and apply the filters to the ListCollectionView.

The filters work fine. But I found whenever there are multiple derived types of instances in the collection, the RadGridView shows the rows but the content in all the cells are empty. 

I checked the output and did not see any GUI exception.

Is it a known issue? Is there any solution for this?


Thanks,
Stephen

I'm binding my carousel to a child collection of an item on my ViewModel. This collection is an EntityCollection, but when I add an item to that bound collection, it's not being reflected in the carousel. It's not picking up the change.

My bound collection is a child collection to a EF entity object on my viewModel. I've tried capturing the event on my viewmodel and Raising a PropertyChanged on it, but that doesn't work either. My code is being fired, but that isn't updating the carousel. Maybe because I'm raising a propertyChanged, not a collection Changed?

Hello,

We have an issue with a radgridview where we have custom expandability setup on the rows. When we sort on a column, the rows that have IsExpandable set to false get set back to true after the sort has happened. We set up a custom binding for the IsExpandable properties on the rows that have it set to false initially to get an idea of whats happening to cause it to go back to true on the sort. Here is the callstack:

Hi,

I have a wpf project and I create a semi-transparent balck UserControl with a RadBusyIndicatror to indicate to my users that a synch job is being in progress.

The problem is when the job start, it's look like the job pulling all resources from the cpu and the RadBusyIndcator don't have enough cpu resources to show his fluid animation. The animation start, stop, start, stop, start, stop and so on...

code example:

BusyControl busyControl = new BusyControl();
busyControl.Start("Job in progress. Please wait...");
SynchroneJob();
busyControl.Stop();

Thank's

Hello,

I have entity framework classes, one is DownloadLink and i have these two columns to gird (not binded to any DownloadLink properties)

<telerik:GridViewColumn Header="New F.H.Id" UniqueName="NewFilehostId" Width="*"></telerik:GridViewColumn><telerik:GridViewColumn Header="New URL" UniqueName="NewUrl" Width="*"></telerik:GridViewColumn>

Only easy way to iterate row i found is using  radGridViewReuploadStatus.Items, but that way i can't access those two added columns.

So i think easiest way would be to somehow extend DownloadLink and add these two new fields, i tried it like this

class DownloadLinkExtended : DownloadLink {
        public DownloadLinkExtended(DownloadLink origDl){
            PropertyInfo[] myObjectProperties = origDl.GetType().GetProperties(); //BindingFlags.Public | BindingFlags.NonPublic
            foreach (PropertyInfo pi in myObjectProperties)
            {
                object value = pi.GetValue(origDl, null);
 
                if (value != null)
                {
                    try
                    {
                        pi.SetValue(this, value, null);
                    }
                    catch (Exception) { 
                        //selze to na komplexnim typu jako napr. PostData
                    }
                }
            }
        }
 
        public string NewUrl { get; set; }
        public string NewIdOnFilehost { get; set; }
    }

But well that reflection does not work and i don't have it set up like DownloadLinkExtended.DownloadLink because then every grid bound column would need to be DownloadLink.field and i don't want it that way. Also setting it in constructor for each property individually is to much error prone manual work.

Other solution would be to get rows somehow like this

IList<GridViewRow> rows = radGridView.ChildrenOfType<GridViewRow>();

But since there is no .Rows this it seams to me that it is not your recommended way.

So what is ideal solution. Or how to nicely extend my DownloadLink class to include that two new required fields?

Hi,

Looks like RadDragAndDropManager is not ThreadStatic which causes application crash as We have UI in two different threads.

I have RadDragAndDropManager.EnableNativeDrag = true set in my Base control Constructor. 

Now that base control is used at multiple places in my application. 
In our main UI thread we have this control and from this thread we started another thread which has UI and in that window we make use of our control at many places in various window forms. And so whenever we open a window which contain that base control lookslike RadDragAndManager call the reset function on  DesktopDragDropProvider object. 

But when I go back to first UI Thread and click on the control that is using RadDragAndDropManager UE occurs.

In my understanding RadDragAndDropManager should be ThreadStatic rather than just the static. that might solve the problem.
