Problems with RulerScaleSize in weekview

I have a RadScheduler (RadScheduler1) set to weekview and setting the RulerScaleSize to 15, and the ShowWeekends set to false. On the form I have a checkbox (chkShowEnds) for "Show Weekends", with the following code in it's click event.

Dim weekview as SchedulerWeekVview = Me.RadScheduler1.GetWeekView()
weekview.ShowWeekend = Me.chkShowEnds.Checked

It set the ShowWeekends property, and the RadScheduler weekends appear and disappear correctly. However, on the first click it sets the RulerScaleSize to some default setting of about 25 or so, and I can not seem to set it back to 15. I tried testing around with setting the RulerScaleSize and it seems to set to a larger value, but not smaller ones. It also seems to change the RulerScaleSize the first time, but not subsequent times.

Any help woul dbe appreciated.

[Solved] ContextMenu for ListBox Item

I have a list box with some items in it. I have a ContextMenu assigned to the ListBox

I want to add logic to the "DropDownOpening" event so that the menu only displays when an ITEM is right clicked, and that is contextual for that item.

I don't seem to be able to work out how to retrieve the item over which the right click was made.

I've tried listBox.SelectedItem but that doesn't work as the right click isn't moving the selection

I've also tried listBox.GetChildAtPoint(contextMenu.DropDown.Location) - but that always returns null

Any help greatly appreciated.

Custom sorting with connected rows

Hi,

I'm using a GridView to display "Order Items".
Order Items can be arranged hierarchically by setting the Property "ParentOrderItemID" equal to the Property "OrderItemID" of the parent order item. Please not I can NOT use hierarchical grids.

What I want to do now is enabling custom sorting the following way:
If the User sorts by a certain attribute the sort algorithm must still keep together connected rows.

Say the grid has the following structure
[Order Item ID | Parent Order Item ID | Gross Value]

And the following values
[1 | null | 30]
[2 | 1 | 20]
[3 | 1 | 15]
[4 | null | 10]

If I now sort by "Gross Value", I want the sorted result to be:
[4 | null | 10]
[1 | null | 30]
[3 | 1 | 15]
[2 | 1 | 20]

How can I do it? I tried to use CustomSorting Event, but I'm stuck.

private void orderItems_grid_CustomSorting(object sender, GridViewCustomSortingEventArgs e)

{

if (this.orderItems_grid.SortDescriptors.Count == 0)

{

return;

}

int result = 0;

SD_OrderItems item1 = e.Row1.DataBoundItem as SD_OrderItems;

SD_OrderItems item2 = e.Row2.DataBoundItem as SD_OrderItems;

for (int i = 0; i < this.orderItems_grid.SortDescriptors.Count; i++)

{

string cellValue1 = e.Row1.Cells[this.orderItems_grid.SortDescriptors[i].PropertyName].Value.ToString();

string cellValue2 = e.Row2.Cells[this.orderItems_grid.SortDescriptors[i].PropertyName].Value.ToString();

if (item1.ParentOrderItem.HasValue && item2.ParentOrderItem.HasValue)

{

if (item1.ParentOrderItem.Value == item2.ParentOrderItem.Value)

result = cellValue1.CompareTo(cellValue2);

else

result = item1.ParentOrderItem.Value.CompareTo(item2.ParentOrderItem.Value);

}

else

{

result = cellValue1.CompareTo(cellValue2);

}

if (result != 0)

{

if (this.orderItems_grid.SortDescriptors[i].Direction == ListSortDirection.Descending)

{

result *= -1;

}

break;

}

e.SortResult = result;

}

Any help would be appreciated.

Thank you!

[Solved] Edit Mode

Hi,

I need this functionality in my application that when user is in edit mode in a cell and then leaves the cell, then next selected cell should not be in edit mode. Means leaving an editable cell should bring the grid out of editable mode no matter user leaves the editable cell by pressing right or left key or by using mouse . Can anyone help about it? Any help would be appreciated.

Thanks

[Solved] Appointment Icon

We'd like to have the ability to add icon overlays to appointments. I don't see this functionality documented anywhere, so I assume that its not implemented directly. So my next question's would be:

Are appointments drawn using their own individual OnDraw() ? If so, where do I look to grab the drawing rectangle and graphics handle for an appointment object.

If they are drawn on the schedule using the GDI graphics object of the scheduler grid, is there and accessible collection of rects for the current view, or would the control have to be extended manually. Obviously the latter option would be a last resort, since the layout logic would be a lot of work.

I know I could look at the source and find this out on my own, but where is the fun in that.

Thanks,
Chris

[Solved] How to theme the RadPageView in “ExplorerBar” as ViewMode

Hello,

I have created a custom theme for an application and I would like to know how I can theme the ExplorerBar view mode.

While exporting the premade theme “ControlDefault” as example, I only find these files in my directory:

- ControlDefault_RadPageView_Telerik_WinControls_RootRadElement.xml

- ControlDefault_RadPageView_Telerik_WinControls_UI_RadPageViewOutlookElement.xml

- ControlDefault_RadPageView_Telerik_WinControls_UI_RadPageViewStackElement.xml

- ControlDefault_RadPageView_Telerik_WinControls_UI_RadPageViewStripElement.xml

I am trying to create by myself the missing one (“_RadPageViewExplorerBarElement.xml”), but I fails in this task.

Can you please provide me this xml as example?

I am currently working in version 2010_2_10_914 (Q2SP2).

Thank you.

I found this code in your page for assign shortcuts on buttons and controls differents to radmenuitem:

Me.RadButton1.ButtonElement.Shortcuts.Add(New RadShortcut(Keys.Control, Keys.B))

The problem is when I write Me.RadButton1.ButtonElement. the word Shortcuts isn´t in the list. Also, appears the following error:

Shortcuts aren´t a member of Telerik.Wincontrols.UI.RadButtonElement

Thanks.

Determine active child form in MDI app

I am using Dock and RibbonBar (Q2 2009 release) to design a UI. I have the Dock control set to AutoDetectMdiChildren, and can easily add forms as tabbed documents. What I would like to do is change the active RibbonTab based on the active child form in Dock so that the commands match the active document.

I thought this would be relatively easy to do, but I seem to be stuck.

I have implemented an event handler for the ActiveWindowChanged event of the Dock control. I can obviously gain access to the DockWindow via the DockWindowEventArgs parameter. What I haven't been able to do is determine the type of form that the DockWindow represents. Basically what I would like to be able to do is something like this:

                    if (DockWindow is SettingsForm)         
            {         
              // Change to appropriate RadRibbonTab         
            }         
            else         
            {         
             // do something else         
            }         

It seems like there should be a way of doing something like this without having to iterate over the MdiChildren array and I would be at all surprised if I am looking at this the wrong way.
