[Solved] Filtering on booleans / checkboxes not intuitive

2008Q2

The grid displays boolean column as check box, the filter on the column in on
(default), the filter checkbox is not checked - the grid displays all rows.

If the user checks the checkbox, the grid filters all rows that are also checked.
Now if the user clears the checkbox, the grid filters all rows that are
not checked. So far, so good.

The problem is, it's not intuitive for the user, since he has no visual clue,
that filtering is still active. (The UI looks the same as before the initial checking,
but the result is not the same.) Would be nice if the filter symbol would indicate
active filters, or how about a 3 state checkbox?

[Solved] Group property null for GridColumnGroupCellElement

I'm trying to add some a custom menu item when the user clicks on a GridColumnGroupCellElement to hide all columns below this group. However, the Group property of the GridColumnGroupCellElement is always null and the ColumnIndex is -1. Is there any way to determine the GridViewColumn or GroupViewColumnGroup that this element belongs to?

This is the code i'm currently using

    
            private void Grid_ContextMenuOpening(object sender, Telerik.WinControls.UI.ContextMenuOpeningEventArgs e)  
        
            {  
        
                if (e.ContextMenuProvider.GetType() == typeof(GridColumnGroupCellElement))  
        
                {  
        
                    GridColumnGroupCellElement element = (GridColumnGroupCellElement)e.ContextMenuProvider;  
        
                    GridViewColumnGroup group = element.Group; // this is always null  
        
                    RadMenuItem customItem = new RadMenuItem("Hide Group", "HideGroup");  
        
                    customItem.Tag = group;  
        
                    customItem.Click += new EventHandler(Grid_ContextMenu_HideGroup_Click);  
        
                    e.ContextMenu.Items.Add(customItem);  
        
                }  
        
            }

Thank you,
Tim

RadPanelBar remembering position?

Currently I have two overlapped Panel Bars, each with their own lists. By clicking on one it hides the original and makes the other one visible. On the bottom of the other panel bar is a ToggleButtonElement that hides the panel bar and returns to the other view. My question is how can i focus on the original element clicked so the user doesn't need to scroll all the way down to where he or she was before it made the switch? Because of the amount of elements in these panel bars and the targeted platform I had to do it this way.

Here is a visual description of what I am doing:

Panel Bar 1
---------------
Group 1
Group 2
Group 3

By clicking on Group 2, Panel bar 1 becomes hidden and Panel Bar 2 is visible.

Panel Bar 2
---------------
Element 1
Element 2
Back to Groups Element

By clicking on "Back to Groups", Panel Bar 1 is now visible again.

Thanks.

Control doesn't appear in Form

Good Afternoon,

When I try to build a windows forms application and try to drag a RadGridView control onto the form it doesn't appear on the form itself but on the grey bar at the bottom of the designer view. I have attached a screenshot to illustrate what I mean.

When I to do anything with the grid in unbound mode or by data binding it (I've tried with lists and data tables) and then run the application, the form simply does not show the grid.

I'm using the dlls only and have imported them as references to the project, imported them to the toolbar and added the following assemblies using the gacutil tool:
TelerikCommon, Telerik.WinControls, Telerik.WinControls.GridView, Telerik.WinControls.UI

The version of the assemblies is 2010.1.10.308.

I have, so far, been able to successfully add other Telerik winforms controls to forms and use them.

Any ideas?

Thanks in advance.

ComboBox and ListBox Adding Objects

Hello!

I know this topic has been discussed here quite often, but I can't get it to work and because they were written a long time ago maybe there are new informations for this.

My target is to add Objects in a RadComboBox or RadListBox (maybe it's supported now).
The first step is to bind a List<Object> to the Controls DataSource, then I fill the List but nothing is drawn/added to the control. If have checked both counts (ComboBox and List), ComboBox is 0 und List not. What is the reason?

Next thing I don't know exactly, is how to get the selected Objects. Im using a workaround by getting the Index of the Item and then getting the real Object from the list using the index. Is this correct or should I use another way?

Maybe someone can give me a solution for this, how to work with ComboBoxes and ListBoxes with my own Objects.

Thanks for your help,
regards
Juergen

Custom Themes buggy and don't work

I have changed this post from the original to focus on the main problem I am having. I am using the newest version of VSB and Winforms in a C# application. The app uses a RadShapedForm with ThemeManager and the repository.xml and theme.xml loaded into it. My RadTitleBar uses three images for the min, max and close buttons as well as three more mouse over buttons. While the gradient fills work on the title bar none of the images show up in the VS2008 designer or at run time. Also I noticed that after loading the saved repository back in the VSB the images are missing there as well. Why aren’t the images showing up in Visual Studio and why does the VSB loose the location of the images after it is saved. I am guessing the VSB is not saving the correct location of the images for some reason but I have no way to check it because the string is not readable. Can anyone help?

I have attaches two images, one is the missing images on the visual studio designer and the other ris the missing images in th VSB after loading the saved repository.

handling reservations in Scheduler

Hi,

I am in the process of upgrading an exisiting winforms application that manages room reservations.

Currently we are just showing the reservations in a grid. I am planning to use the RadScheduler to show the reservations.

I already have a Reservation Class as follows.

    
            public class Reservation 
        
            { 
        
               public int ReservationId { get; set; } 
        
               public DateTime RequestDate { get; set; } 
        
               public string RequestedByName { get; set; } 
        
               public DateTime StartDate { get; set; } 
        
               public DateTime EndDate { get; set; } 
        
               public string Comments { get; set; } 
        
               public int RoomId { get; set; } 
        
            }

How do I go about using the above class to populate the scheduler. The only thing I can think of is to map the above class to the Appointment class for populating the scheduler. Is there an easier way?

My other question is how do I go about using the Reservation Form that I have already created instead of the Appointment Dialog that the scheduler displays by default when the user wants to edit / create reservations.

thanks
