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!
Stefan

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

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

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.

Hi:

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.

Visual Inheritance

I'm trying to inherit from a base form with a telerik grid. The grid's modifier is set to protected. On the inheriting form, the grid appears but completely disables as if it's modifier is Privet (it's not). Other controls (Microsoft + Telerik) are not showing this behaviour. They are working properly when their modifier is set to protected.

Kindly help me in this regard.

child tabs in Hierarchy multiple relations

Hi There,

I have a project that I have currently started to rebuild with the latest version of the telerik controls that seems to behave differently than the initial project did with version 2009 Q2. Basically I have a grid that has 3 child tabs for each row using this example:

Main Grid

User Information
--HR Data --Security Group Membership --Users who report to this person

the problem is HR Data always has information in the sub tab, however Security and / or Users who report might not.

the problem that I am getting now is that in the previous version of the gird I would see the child row with the headers and no information below so for instance:

HR - DATA
Full Name        Phone                Home Address
first last          555-111-222        example lane

Security Group
GroupName     GroupOwner        GroupType

the problem is now if there is no data for Security group the tab is now displayed as such:

HR - DATA
Full Name        Phone                Home Address
first last          555-111-222        example lane

Security Group
Full Name        Phone                Home Address
first last          555-111-222        example lane

If there is no data in the child tab grid, can I hide that tab or is it possible to set where I still see the column headers without any data in the grid.

thanks!

Jonathan

StackOverflow

For some reason, I get a StackOverflow exception when the command bar is on my dialog and from the parent form I call

dlg.ShowDialog(this);

I've created a base dialog from which other's are derived. All of them behave fine; however this one fails every single time .ShowDialog() is called.
