Change ComboItem row height and color

Hi:

How can I change the row height for the dropdown items? The default is too spaced out; I'd like to reduce the height. Also, the defaul background color of a selected row is orange. Kind'a gross. How can I change that? Finally, I know for teach column, we can use bestfit() to set it's width. Is there a way to set the dropdown width so that is will automatically fit according the the columns. All I see as examples are giving the dropdown width a fixed value (e.g.: = 500). That is dissatisfactory because I have no way of know how wide by individual columns will be - it depends on the subset of data returned. So, I may have lots of extra whit space sometimes (when the combined column with is less that what I've set for the dropdown width). Other times, I need to horizontal scroll to see all the columns because the dropdown width is not set large enough. Neither situation is desired. . .

Thanks!

Problem with cellformatting and horizontal scroll

Hello,

I have a grid with a status column in which I want to place a red o green ball depending the bound value. I've tried to do that with the next code:

Private Sub Grid_CellFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) _

Handles gridPedidos.CellFormatting, _

gridChrono.CellFormatting, _

gridCentros.CellFormatting, _

gridIncidencias.CellFormatting, _

gridIncidenciasPFR.CellFormatting, _

gridPedidosWeb.CellFormatting

e.CellElement.Image = Nothing

Dim column As GridViewCommandColumn = TryCast(e.CellElement.ColumnInfo, GridViewCommandColumn)

If column IsNot Nothing Then

Select Case column.UniqueName

Case "Txt"

CType(e.CellElement.Children(0), RadButtonElement).Image = My.Resources.document_text

CType(e.CellElement.Children(0), RadButtonElement).ImageAlignment = ImageLayout.Center

Case "Datos"

CType(e.CellElement.Children(0), RadButtonElement).Image = My.Resources.table_view

CType(e.CellElement.Children(0), RadButtonElement).ImageAlignment = ImageLayout.Center

End Select

End If

If e.CellElement.ColumnInfo.Name = "Status" AndAlso TypeOf e.CellElement.RowInfo Is GridViewDataRowInfo Then

Dim Status As Integer = CInt(e.CellElement.RowInfo.Cells("Status").Value)

If Status = 0 Then

e.CellElement.Image = My.Resources.button_green

Else

e.CellElement.Image = My.Resources.button_red

End If

e.CellElement.Text = ""

End If

End Sub

Executing the program the status column is draw right as you can see in the image1 attached. But scrolling horizontally right and left, the red and green balls are showed in other columns (image2)

Thanks in advance
Blas

Visual Studio crashes while in "Edit UI Elements" of RadTextBox

I am using Visual Studio 2008 with the latest Telerik Winforms. If, for example, I drag a RadTextBox from the toolbox, and click "Edit UI Elements". Then, I choose FillPrimitive and attempt to set SmoothingMode to something like, say, "Invalid" (among other options)

Then immediately Visual Studio would say RadTextBox has thrown an exception in the designer and has been disabled. Error message is "Parameter is not valid" and no stack trace is available. The "element hierarchy editor " dialog is closed and VS hangs with 100% CPU usage (I have to terminate devenv.exe task to recover).

I know this is not a valid use case but should this be handled more gracefully? The exception dialog is OK but at least VS should not hang.

Modify Filter Behavior

I am trying to change the filter element behavior of a ComboBoxColumn. I would like the ComboBoxColumn filter element to behave identical to the filter element for a TextBoxColumn. I need the filtering to be textbased instead of a drop down and I need the DisplayElement to be filtered as opposed to filtering the ValueMember. Is this possible?

Scroll speed with mouse wheel

Hi,

When I open the drowpdown of a multicolumnbox and use the scrollbar to reach lower items, the scroll speed is fast. However, when I use the scroll wheel on the mouse, the scroll speed is very slow. Is there anything I can do to speed up the mouse wheel scroll speed?
