Can the TextBox of the DateTimePicker be set to read only so that the user cannot manually edit any of the date? I tried using dtp.DateTimePickerElement.TextBoxElement.TextBoxItem.ReadOnly = true, but I was still able to edit the day.
When a minDate value is set it appears to the user that they can edit the day and be able to be set the date to a date less than the min date. Worse yet, say you have a minDate of 5/19/2008 and 5/20/2008 is selected. If you edit the day to 31 and then edit it again to 15, it will stay at 31 (display = 5/15/2008, value = 5/31/2008). Very confusing.
In the constructor, I set the MinDate, NullDate and value of the DateTimePicker = DateTime.Today. If today is 5/19/2008, using the Picker I cannot select 5/19/2008. I can only select 5/20/2008 and greater.
Are there properties that I need to set to avoid this situation?
Thanks,
Mike

Hi - I have set the ShowCheckBox Property to True for my RadDateTimePicker (version 2009 Q1). It appears the alignment is Top,Left. How do I center it so it's consistent with the text?

Hi,
I have a grid which can contain more than one screen-ful of data. After population I call BestFitColumns() to auto-size the grid columns, but the logic is only applied to the visible rows. I want the columns to be resized based on ALL rows in the grid, since if the user scrolls down they see truncated cells.
Is this possible?
Regards

I am using a GridSpinEditor in my decimal columns, but when the user clicks on a cell has a null value and is initially blank, a 0.00 is entered into the cell editor automatically. Thus the value is changed without the user making any changes other than clicking in the cell. I need to leave the value blank unless the user actually changes it - i.e. have the editor's initial value be blank if the data is null. I have tried using NullValue, DefaultValue, and even setting the text to blank inside CellEditorInitialized, but the 0.00 still shows up! Is there a way to fix this?
Thank you,
Rachel

Hi everybody.
I have a gridview with 3 columns, one of which is a of gridviewcheckboxcolumn type. gridviewcheckboxcolumn is only one which can be edited, and additionally is unbound. Now I'm trying to check/uncheck cells in gridviewcheckboxcolumn but nothing happens. It seems like the cells are read only. Do I have to write an cell event handler, or may be just to set some column proprieties?
Thanks.
Best regards, Frank.

I have a chart that is bound to a datasource. When data is updated in the table, the chart is not refreshed or updated. I have tried:
.update()
.updategraphics()
.refresh()
And also:
.datasource= mybindingsource
.databind()
The latter causes a large red X to be displayed instead of a chart.
Any help?

Hi,
I am adding the RadPanelbarGroupElement in RadPanelbar control on Runtime and adding the populated Treeview control in each group. The RadPanelbar is in OutlookNav style and for each group, EnableHostControlMode is true.
Everything works fine but if I click any of the Groups 4 times, the whole application hangs.
Please suggest. See the code below:

foreach (Task task in group.Tasks)

rootNode.Nodes.Add(taskNode);
}
}
}
}

I have a MaskEditBox for a phone number. When I click out or tab out of the maskeditbox the value is replaced with (___) ___-____. Is there a property that I need to set or some other workaround to fix this?
