I get this exception trying to filter a column on a radgridview setup as "Excel-like" mode.

The colum shows the "Duration" and it is a "TimeSpan" databind type.

Any help would be appreciated.

How to customise the display of listview items

Hi there.

I'm currently evaluating Telerik for an upcoming personal project.

The attached image is a very crude mock up of the type of look I'd like to achieve with the list view control, but I'm running into a few walls. Most other controls I've been able to work my way around but no so far with ListView.

I'm the control to show all items in ViewType ListView, Each item will have a thumb nail image, and I'd like to display a main header text (Series Name) with associated sub text of differing fonts and sizes. This is where I'm stumbling, any assistance would be greatly appreciated.

TimePicker Defaults

I'm writing a time entry program that will require a lot of time pickers on a single form. I have to do some math to add up the hours based on TimeIn and TimeOut for each shift.

I set the control to a default date and time on load. The trouble I'm having is when the user changes a time using the picker, the date reverts to the current date. The result is my date math is wrong. If the TimeIn date and time is set to 10/21/2014 1:00 AM on load and they change the time to 2:00 AM, I'm getting 10/24/2014 2:00 AM, which is a problem for my math.

1) Is there are way to format the radtimepicker to be time only and return a time only value? I don't care about the date portion at all. I'm just using these to get hours worked in a single day.

2) Alternatively, since I'm stashing the times in a database, is there someway to keep the date from changing? I can work with a fixed date for time calculations.

Thanks

Using Composite Filters question

Based on the example here - http://www.telerik.com/help/winforms/multicolumncombobox-filtering.html
I cannot get the composite filters to work. The single filter works fine.

Based on the code below, once I bind the data to the datasource, the DisplayMember is automatically set to the first column, in this case Account. The documentation says the data is filtered by the DisplayMember field. So this works fine for the single column filter.

For the composite filter, no filtering takes place. You can see from the attached debug image that the filter is being set correctly.
> Is it because the DisplayMember is only set to "Account"?
> Can it be set to something that would work correctly (eg: Account, Description)?

If the composite filtering does not work, please remove it from the Telerik documentation or detail how to get it to work. A two column drop down is a pretty simple example. BTW I am on Winforms v2013.3.1127.40

Thanks!

Dim sSql As String = "Select Account, Description From accounts Order By Account"

cbo.DataSource = tbl

'THIS single filter section works fine

cbo.AutoFilter = True

Dim filter As New FilterDescriptor(cbo.DisplayMember, FilterOperator.Contains, "")

cbo.EditorControl.MasterTemplate.FilterDescriptors.Add(filter)

'THIS composite filter does not work - duplicated from Telerik example

'Dim cmpFilter As New CompositeFilterDescriptor()

'Dim fltMain As New FilterDescriptor(cbo.DisplayMember, FilterOperator.Contains, "")

'Dim fltDesc As New FilterDescriptor("Description", FilterOperator.Contains, "")

'cmpFilter.FilterDescriptors.Add(fltMain)

'cmpFilter.FilterDescriptors.Add(fltDesc)

'cmpFilter.LogicalOperator = FilterLogicalOperator.[Or]

'cbo.EditorControl.FilterDescriptors.Add(cmpFilter)

load DocumentWindow in invisible mode

how to load DocumentWindow in invisible mode?

I open the second and subsequent tabs:

Form privatForm= new Form();

privatForm.Dock = DockStyle.Fill;

privatForm.TopLevel = false;

DocumentWindow privatDockForm = new DocumentWindow();

privatDockForm.CloseAction = DockWindowCloseAction.Hide;

privatDockForm.Text = tabName;

privatDockForm.Controls.Add(privatForm);

generalFrm.radDock1.AddDocument(privatDockForm);

privatDockForm.Show();

privatForm.Show();

Not running the event PrivatForm_Load until the user activates it... How to force a load of my privatForm without displaying it to the user?
and how to add DocumentWindow in the Dock temporarily without creating a tab?

Saving all dock controls?

Hey all -

I've played with a few different bits of code to save the Dock controls, and was wondering if I was missing an easy way to save them in the app?

The code dockingManager1.SaveXML(FileName); and dockingManager1.loadXML(FileName); only saves the dock structure, but not any of the internal controls.

Thanks in advance,
Jim
