Hello,
I have a problem with the shape of the tabstripitem with Q2 2011:
In the previous libraries version the shape of the tabstrip didn' t overcome the text of the tabstrip, while now it does (the shape is a Vs Tab shape).
I want to restore the old shape/text relation.

As attachement screenshot of the actual and desired layout.

Thank you in advance.

Alternating and Selected Row color issues

First, I am unable to get alternating row color to work. I have implemented it like this article says (http://www.telerik.com/help/winforms/gridview-styling-and-appearance-alternating-row-color.html) but all the columns remain white. Can you please tell me in which method to put

CType(Me.RadGridView1.TableElement, GridTableElement).AlternatingRowColor = Color.Yellow

I have tried in the form load and other events of the grid, like row formatting.

Also, I am trying to implement the hover over and selected row color but when I set the Row Formatting like the following article (http://www.telerik.com/community/forums/winforms/gridview/change-color-of-selected-row-in-gridview.aspx) the row is highlighted with orange and of the two columns in the row, the one that is not selected is the correct color, blue. This changes when I click on the other cell in the row. Furthermore, the cell that is blue still has an orange border.

Binding to Subclasses

I want to use collapsable Key-Name pairs, similar to Points(x,y) which show on one line but can be expanded to separate x and y lines.
But I do not see the Subclass Fields in the property grid. What is missing?

//some Subclasses

[Category("Detail")]

public class WorktypeInfo

{

private string _WorktypeNo;

private string _WorktypeName;

[Category("Detail")]

public string WorktypeNo

{

get

{

return _WorktypeNo;

}

set

{

_WorktypeNo = value;

}

//used in Mainclass

[Category("Detail")]

[Description("Tätigkeitscode")]

public WorktypeInfo WorktypeInfo

{

get

{

return _WorktypeInfo;

}

set

{

_WorktypeInfo = value;

}

...

Any help is appreciated...Thanks Daniel

Hi



The above code loads my multi-column list box. However I would like to add <All Suppliers> at the beginning of the list as well as the supplier. I would like this to be the item selected on load.



Also, I cant find the equivalent command for combobox.items.clear() 



How do I remove all the items?



Cheers

Check Back color of cell

Okay, I'm successfully changing the backcolor of cells in my grid based on the data being populated.

What I want to do now is when a button is clicked, check to see if any of the cells still have a red background.

However, I cannot seem to get any property that will tell me if the cell has a background color of Color.Red.

Here is the code I've been trying:

for (int iRow = 0; iRow < ProductsRadGridView.Rows.Count; iRow++)
{
          for (int iCell = 2; iCell < 6; iCell++)
          {
                    if (ProductsRadGridView.Rows[iRow].Cells[iCell].Style.BackColor == Color.Red)
                    {

}

                    //valid = false;
                    //MessageBox.Show("One or more Line Item Values needs modification. Please make the necessary change.);
                    //return valid;
          }
}

However, the Style.BackColor returns some ambigous name called "ControlDarkDark". This is the value regardless of the back color.

How can I check what the back color really is?

Select Appointment

Hi,

I have been working on a function that allows a user to search for an appointment ID, and the appointment corresponding to the appointment ID is highlighted/selected.

I have been able to do this by using the following:

Dim appt As IEvent = Nothing

appt = GetAppointment(CLng(msSearchID))

If appt IsNot Nothing Then

SchedulerUIHelper.SelectAppointment(radScheduler1, appt, True)

End If

Private Function GetAppointment(ByVal nID As Long) As IEvent

Dim appt As IEvent = Nothing

Try

For Each a As IEvent In radScheduler1.Appointments

If a.UniqueId.KeyValue = CStr(nID) Then

appt = a

End If

Next

Return appt

Catch ex As Exception

Return appt

End Try

End Function

However, an appointment which has a RecurrenceRule (a master appointment) is not being highlighted. Recurring Appointments are also not being highlighted, but this is understandable as radScheduler1.Appointments collection does not have separate instances of the recurrence, but it does have the master appointment.

For example, an Appointment with ID 45 is a master appointment with 4 more appointments recurring daily. If the user enters 45, we select this appointment from the GetAppointment function as shown above, then pass it to SchedulerUIHelper.SelectAppointment to highlight this. The SelectAppointment method does not work, even though we pass the correct IEvent to it.

Alternatively, if the user enters ID 33 (which is a normal appointment without any recurrence rule), then SelectAppointment function does work and the desired appointment is highlighted.

Is this a bug in SchedulerUIHelper.SelectAppointment? If so, how do I implement the same functionality as the SelectAppointment function?

Thanks,

Scheduler and Reminder

Changing text on SelectedIndexChanged

I have a multi-column combo box with 2 columns using the drop down list style. When the user selects something new, I want to combine the text from both columns and display it in the text area. Is this possible? Even if I set the Text property of the combo box to something new, it still just shows the text from the first column. It does seem to work when initializing the control but not when the selected index is changed.

RadGridView and the ErrorProvider

Is there a way to use the ErrorProvider with the RadGridView. Currently we are using it with the GridDataView. We are wanting to replace the DataGridView's with RadGridView, but the functionality the ErrorProvider provides with the DataGridView is important to us.

Thanks
