Hi experts,
I am using the gridview for windows forms version Q1-2009,
I am developing a vb2008 application which uses the rad grid view in unbound mode, my problem is , is it possible to assign datatype to each column. I mean column 1 as string, 2 as integer like that. If anyone knows the answer kindly replay me.
Thanks in advance

Hi
I have a radgridview which has a column whose value is set by an expression:
Me.StockGrid.Columns("Total").Expression = "(Qty) *" & CInt(Me.radtextbox1.Text)
I want to use the result of the expression to populate another column in the same grid.
Me.StockGrid.Columns("req").Expression = "(Total – Available)”
The result is always nothing although the total column value calculated by the first expression has a value and available has a value. Is this type of calculation valid?
Regards

Hello world,
I am discovering Telerik and I am pretty impressed so far. However, two problems have arisen:
1. Why does it take 5 seconds to show a simple form with just an empty Gridview inside? With the standard datagridview, it is instantaneous. Am I missing a point? I can't believe everyone who uses the Gridview has to endure waiting for 5 seconds even for empty objects.
You can easily reproduce this problem (just create two forms, one with the rgv and one without, launched from a third one). No need to set up any properties to the rgv to see the low display speed.
I tried to search on the forum for similar issues but Murphy's law is there for me: as the two links I have found are not working!
http://www.telerik.com/community/forums/winforms/gridview/initializing-slow.aspx
WinForms Controls - GridView Forum - Initializing slow
WinForms Controls - GridView Forum - Performance to open
... why just opening the window is very slow? with 4 controls of telerik, it takes 3
or more seconds... Imagine 10 controls!! thanks!! Reply. Telerik Admin. ...

2. When do you intend to implement support for subproperties in the hierarchical view? This is really a must have. I have found forum posts dated 2 years back and still no support for this feature... Is it on the roadmap somewhere? Is there a workaround better than building a virtual database (with plenty of IDs to link the objects together)? For your reference, the latest forum post I found on the subject was this one:
Thanks a lot for your help!

Hello,
I cannot find where I have to modify the style of the RadForm to disable the fact that the color (of the title bar especially) changes (it becomes lighter, with Office2007Black theme) when the form loses focus (if we switch from one form to another).
Any direction would be more than welcome!
Thanks,
Erwin

In the RadControls for Winforms Q3 2009 Beta Demo Application in the gridview TabbedChildViews Demo:
When i change the Tabs Position to left or to right then only two tabs ("Details", "Orders") are displayed and the third tab "Perfromance" is not displayed. When there is not enough space to display all tabs at a position there should be a scrollbar or something like this which should auotmatically be displayed so all tabs could be reached.
Kind Regards,
Ramius

Dear friends,
In my translation activity i could not find how to translate the 'Previous/Next Appointment' buttons in RadScheduler.
Can you help me?
Here's my code:
class TradutorScheduler:RadSchedulerLocalizationProvider
{
public override string GetLocalizedString(string id)
{
switch (id)
{
case RadSchedulerStringId.AppointmentDialogTitle:
return "Nova Tarefa";
case RadSchedulerStringId.AppointmentDialogSubject:
return "Assunto:";
case RadSchedulerStringId.AppointmentDialogDelete:
return "Apagar";
case RadSchedulerStringId.AppointmentDialogCancel:
return "Cancelar";
case RadSchedulerStringId.StatusBusy:
return "Ocupado";
case RadSchedulerStringId.ContextMenuNewAppointment:
return "Nova Tarefa";
case RadSchedulerStringId.ContextMenuNewRecurringAppointment:
return "Nova Tarefa Repetida";
default:
return base.GetLocalizedString(id);
}
}
}
Thanks in advance.

Hi,
I am struggling, after some days of effort, with a trivial implementation of an unbound grid.
Scenario: I have an unbound data object which I am using to populate an editable grid. When the user clicks on the "Add new row" I trap the DefaultValuesNeeded event and populate the grid cells with the default data required for that row. One of the columns is a calculated primary key, which I calculate and provide during the DefaultValuesNeeded event. (Previously I tried using the Row .Tag property but this has a similar problem to that described here).
1) The default values supplied are not visible in the row being edited.
2) When the CellEndEdit event fires, I want to copy the data from the edited cell into my underlying business object. However none of the default values I set for the row are available in the row Cells collection (including, unfortunately the primary key for the newly added row).
How can I use RadGridView to maintain an unbound list of data which has a calculated primary key, and default values ? I am really struggling with this, as it seems to be a really common thing to want to do ?
It would help if I could find a clear list of the events which fire when a row is added, in what order, and what they are intended to do - I may be missing something in the online help, but there doesn't seem to be a clear description. Irrespective of this, it seems that the magic "Add new row" feature is pretty broken if I cannot address the cells on the row during the CellEndEdit event ...
Frustrated.

I'd like to use the grid like Excel.
1. As soon as the user selects a datacell it goes into edit mode (not using F2 or key stroke to enter edit mode). Is this possible?
2. When the user press Enter key, move to next datacell (and go in to Edit mode of course)
3. When in datacell and end of text and user press Right arrow key, move to next datacell (and go in to Edit mode of course)
4. When in datacell and beginning of text and the user press Left arrow key, move to previous datacell (and go in to Edit mode of course)
Everything to get the grid to act as Excel.

In my GridView the user selects a number of rows, and then asks to do some processing based on each of the selected rows, one by one.
The rows are typically selected by "normal" multirow selection, by pressing the shift or ctrl key and clicking the rows/range of rows in question. The last clicked row is then selected, and the arrow to the left is on this row, while the others are marked with blue.
When the processing begins the first (topmost) row and then the rest in sequence. I would like the arrow to follow the row in progress, but by setting CurrentRow, the "multiselection" is cleared, and only the CurrentRow is marked with blue.
Is there a way to programatically move the arrow to the left without clearing the "multiselection"?

Is there an example of this (VB or C#) found anywhere on this site? I seem to be coming up short. I've been learning .net / vb for the past year, but have not had the privilege of coding such an object to date.
We're looking to deploy an organizational-wide (internal) radRibbonForm that would basically be deployed as a floating toolbar for users to gain quick access to internal resources.
The RibbonTab is a great high level way for user to navigate topic, and then within each tab, the RibbonBarGroup contains relavent DropDownButtons, which of course contain ButtonElements...
When I click the buttonElement, I get a 'Win32Exception was unhandled' error.
Here's an example of a particular Button Element's code:
Any assistance would be greatly appreciated (I can post the *.designer.vb if it will help..)

| End Sub |
| Public Sub buttonClickEvent(ByVal sender As Object, ByVal e As EventArgs) Handles rbeD1CPT.Click |
| Dim rbeD1CPT As RadButtonElement = TryCast(sender, RadButtonElement) |
| System.Diagnostics.Process.Start("iexplorer.exe", DirectCast(rbeD1CPT.Tag, String)) |
