Hello,

I have standard control drag and drop in my app, so I have .net DragEnter, DragDrop, DragOver, etc. handlers for the RadGridView in my form. Of course, grid doesn't react properly on mouse activity over it. In my DragOver handler I want to set row under the cursor to hovered state. I found GridTableElement.HoveredRow property, but it is internal. Is there a way to programmatically make grid to set a row into howered state?

Creating a third column in PropertyGrid

Is it possible to create a third column in a PropertyGrid? For example: PropertyName - PropertyValue - Units of Measure (ie: "Starting Length" - "1000" - "meters" or "Base Pressure" - "22" - "psi")

I'm guessing that I might need to create a custom PropertyGrid control that descends from RadPropertyGrid with the third column, and then maybe a custom PropertyStoreItem that includes a field for the third column value (in this case the units of measure). And then somehow bind it all together.

I am new to Telerik, and do not have any experience with your Telerik Presentation Framework.

Thank you.

Attachment field in accdb file

I have a Access database (accdb file), one of its columns contains files with the image in attachment field. When i use this database as Data Source for RadGridView i see only the name of the attached file ("1.jpg", "2.jpg" etc), not the images. How can I see my images on RadGridView without editing database.

Updating row when changing property

Hello,
I'm new to winforms, I've used silverlight a lot in last 2 years... I was wondering why a simple thing I do in SL it seems to me so complicated here. ..

I got a class defined as

public class RapportoItem : INotifyPropertyChanged

{

private int _Thread;

public int Thread

{

get

{

return _Thread;

}

set

{

_Thread = value;

NotifyPropertyChanged("Thread");

}

public int RetryCount { get; set; }

public event PropertyChangedEventHandler PropertyChanged;

private void NotifyPropertyChanged(String info)

{

if (PropertyChanged != null)

{

PropertyChanged(this, new PropertyChangedEventArgs(info));

}

And a

Telerik.WinControls.Data.ObservableCollection<RapportoItem> result = ...

that's bound to the RadGridView using

radGridView1.DataSource= result;

Why when I update the Thread element it's not refreshed in the grid?
Thanks

Paolo

exporting hieararchical gridview

How to not Export specified columns for each parent row child rows when exporting to excel in telerik radgridview ui winf

I a have hierarchical telerik radgridview in winform. in this radgridview master template i have a rows that each row has child rows that are null in some columns for all child rows of that parent row and not for others.

I wrote a code that only let one parent row to be expanded and when expanding that parent row show only the columns that has value at least in one child row and hide columns that its child rows are all null for that parent row with radGridView1_ChildViewExpanded event handler.

My problem is when i want to export this hierarchical telerik radgridview to excel file. what should i do in exporting to achieve to what i described, means exports only the columns that have at least one value in its child rows and not export others for each parent row.

tnx

radDropDownList flashes previous list

I have two radDropDownLists. The contents of the second list change based on the item selected in the first list. When an item is selected in the first list, select the down arrow for the second list, and you see list2 for the item selected in list1. Select another item in list1, and the program changes the items in list2. When you select the down arrow for list2, you see the previous list items flash before the list is updated with list items that correspond to the selection in list1. You can see this demonstrated in Telerik's Demo Application - UI for WinForms. Select DropDown & List and then select First Look. In this example, you select an artist in list1 and the artist's albums are listed in list2. Select artist1 and see artist1's albums in list2. Select artist2 and briefly see artist1's albums flash in list2 and then see artist2's albums. Is there a way to get the list to update before it is displayed so there is not flashing of the previous list?
