Just getting started with Telerik controls...

I need to get the behavior of the RadDropDownList for a column in a GridView.

For the RadDropDownList, I am using databinding to link the SelectedValue to the property of a Business Object or Entity.

I'm trying the same approach in the GridView but no luck.

I have added a GridViewComboBox column and set its DataSource to the list of entities I want in the drop down list. That works fine, and when displaying data the correct item is highlighted. However, trying to pick a new item from the list gives this error: "Object of type 'System.String' cannot be converted to 'mynamespace.Product'.

I can see in the docs it wants me to set the ValueMember to the property on the data source that I want to use, but I don't want to use a property, I want the whole object. How can I do this??

I found this other post and the poster was in the same situation as I am:
http://www.telerik.com/community/forums/winforms/gridview/csla-bindinglist-with-default-objects.aspx

It is from 2010 - so has anything changed or is it still not supported? Do I still have to make up some kind of workaround?

Hi,

I have a radgridview (Q2 2011) in which I am grouping orders by production line. When I move an order by changing the line number in the grid, the row correctly moves to the correct line grouping, however I need to be able to recalculate the subtotals for both the line group that it was removed from in addiition to the line group that it was added to.....I am trying to find the event that fires when the row is moved to another group in the group by definition.....any suggestions / examples are appreciated.

updating the data source based on a value changed

what is the recomanded way to do the following.

On the gridview, when the user edits a cell value, I want to do some computations and assign a new data source to the gridview. I have tried to call refresh on the cell value changed, but that seams to cause a crash.

So I have a hirachy of objects.

Parent
|- Child One
| -> Child Two

During the computation I am getting a new set of Child One objects. With this I mean new instances, which I want to rebind to the grid to show the effect of the edit. It seams that this is not accepted. I can understand that the grid might not expect it's datasource to have change on an cell value changed event, but how can I refresh assign a new data source to grid after an edit and show the changes back to the user ?

[Solved] dtp added to Ribbonbar - how to reference from code-behind

Hello

I have added a telerik dtp to a 'chunk' in a Ribbonbar as follows in the onLoad event of a form. The purpose is to change the view of a calendar when the value in the dtp is changed. The code below accomplishes this task as expected:

Dim dtPicker As New RadDateTimePicker

dtPicker.ThemeName = "Office2007Blue"

AddHandler dtPicker.ValueChanged, AddressOf pickerValueChanged

Dim hostItem As New Telerik.WinControls.RadHostItem(dtPicker)

hostItem.MinSize = New System.Drawing.Size(150, 50)

Me.chunkJumpTo.Items.Add(hostItem)

Me.chunkJumpTo.Items(0).Name = "ggPicker"

The handler that I added is as follows:

Private Sub pickerValueChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

Dim dtp As RadDateTimePicker = sender

selectedDate = dtp.Value

Select Case Me.Calendar1.CurrentView

Case WinForms.CalendarView.WeekRange

viewMonth()

Me.Calendar1.Selection.Set(selectedDate)

Case WinForms.CalendarView.Timetable

If Calendar1.TimetableSettings.VisibleColumns > 1 Then

viewWeek()

Me.Calendar1.Selection.Set(selectedDate)

Else

viewDay()

End If

End Select

setCurrentMonth()

End Sub

However, I would like to change the value of the dtp if a new date is clicked on the calendar itself - how can I reference the dtp in the Ribbonbar and change the value that is displayed?

I found some code from another post - I can find the dtp by doing this (I think) but have not been successful in updating the value...

For Each ct As RadItem In Me.chunkJumpTo.Items
If ct.Name = "ggPicker" Then
...CHANGE VALUE HERE...
End If
Next

QUESTION 2:

I have several RadImageButtonElements in my Ribbonbar. I have set the ImageHovered property on several buttons but the new image is not displayed on hover of the button - are there issues with this property? Can you please demonstrate how to display a second image on hover and then revert to this original?

Thank you

Brian
