This is probably a very dumb question.

Hi:

I have a strange problem that I could solve and it's driving me nuts!

I have dynamically added a Lookup column to my grid during form load:

    c = New GridViewLookUpColumn("ColFinalGrade_Manual", "FinalGrade_Manual")
    c.ValueMember = "GdRule_GradeCode"
    c.DisplayMember = "GdRule_GradeCode"
    c.DataSource = ds_Gd.Tables(0)
    RGV_StdEnrl.MasterGridViewTemplate.Columns.Insert(RGV_StdEnrl.Columns.Count - 1, c)

Then during CellBeginEdit of the grid, I have the following codes (except from longer codes)

    If RGV_StdEnrl.Columns(e.ColumnIndex).UniqueName = "ColFinalGrade_Manual" Then
        Dim editor As IInputEditor = Me.RGV_StdEnrl.ActiveEditor
        If Not editor Is Nothing AndAlso TypeOf (editor) Is RadComboBoxEditor Then
            Dim comboElement As RadComboBoxElement = CType(CType(editor, RadComboBoxEditor).EditorElement, RadComboBoxElement)
                            For I As Integer = 0 To comboElement.Items.Count - 1   (!!!!!PROBLEM IS HERE!!!!)
                                If comboElement.Items(I).Text = "" & RGV_StdEnrl.MasterGridViewTemplate.Rows(e.RowIndex).Cells("ColFinalGrade_Manual").Value Then
                                    comboElement.SelectedIndex = I
                                    Exit For
                                End If
                            Next
    . . .

The problem is:  The item count for comboElement is ALWAYS 0 when I click on that particular cell FOR THE FIRST TIME after the form is loaded. So, the correct value never gets selected.  In fact, during the FIRST run of CellBeginEdit, the DataSource for the comboElement is ALWAYS Nothing.  There is nothing I could do to change that. EVEN IF I first test for it begin nothing and then try to assign it a datasource at that time (If comboElement.DataSource Is Nothing Then comboElement.DataSource = theTable), the item count for the comboElement remains 0.  It almost as if it doesn't want to take anything. No error is generated either.

The strangest part is: This problem only happens ONCE every form load (the very first time that cell is click).  After that, the above code works exact as it should.

I'm just stumped, and would appreciate some help on this.

Thanks!

I have a check box column in a RadGridView, and I can't seem to make it read only.  I've searched through the forums, and only found people with the opposite problem.  I've seen posts about people with read only grids where they want one column editable.  What I want is a checkbox column that is NOT editable, but try as I might, you can edit the check boxes in this grid.

I set the grid's ReadOnly property to True.
I set the individual column's ReadOnly property to True.
I set the grid's AllowEditRow to False.
I even set the grid's BeginEditMode property to BeginEditProgrammatically.

Nothing has any effect.  What do I have to do to make a simple read-only grid?

hi,

i use RadWinforms 2010 Q2 in c# 2008 ,

i inherited a customized textbox from RadTextBox , everything works fine except that theme is not applying to this new control, the control have black borders and does not have the same look of RadTextbox,

how should i fix it ?

Is there something I'm missing... I have the Ribbonbar with the Office2007Black theme.  I set the tab shapes to TabVsShape and I can see it at design time.  However, the tabs are still rectangular at run-time.  What am I missing?

Hi,

in my RadRibbonBar are 4 RadButtonElements in the QuickAccessToolBar (radRibbonBar.QuickAccessToolBarItems).
Now i want to collapse one or more Buttons at runtime. Therefor i've set the Visibility-Propertie of the RadButtonElement to Collapsed:

radButtonElement.Visibility = Telerik.WinControls.ElementVisibility.Collapsed;
Nothing happens.

Than i try to refresh parts of, or the whole, the RibbonBar.
At first i tried it with RadButtonElement.UpdateLayout(). - Same result, nothing happens.
Next i've used the Refresh- and Update-Methode of the RibbonBar - still no results.
And at last i've add a new RadButtonElement to the QuickAccessToolBarItems of RibbonBar in the hope that the RibboBar now refresh itself.

I only want to hide one or more Buttons programmatically.
Can you explain me, how to get it working?


Regards

Hi,

Working in VB.Net with the last release.

How can I test is there is a verticalscroll bar in my RadGrid ?

Or is there a way to force a column to fit the space unused ?

Thanks

Hello all,

I think I may have found a bug with the Export function for the RadScheduler.  I used the Export function as follows:


and then used this iCal feed in lotus notes and got the error: "The content of this URL does not conform to the iCalendar parsing specification."  At first I thought this was because I was using a custom appointment object and editappointmentdialog.  Here is the contents of the .ics file produced from the export function:


Please note the bolded lines.  This above .ics file did not load correctly in lotus notes and produced the error message I said above.

All I had to do to fix this error and get my ics file correctly working in lotus notes was make the following changes to the above bolded lines:


Can you confirm that setting time zone as ;TZID=Mountain Standard Time: is indeed an issue (for lotus notes)?

EDIT: I found another fix for this.

We can leave the DTSTART and DTEND in VEVENT as is:

BUT we have to add a timezone offset to the DTSTART (in STANDARD and DAYLIGHT) of VTIMEZONE
