How to hide individual navigation items and groups for certain users

December 31, 2000, 4:00 pm
$
0
0

Scenario:


Our Security System allows hiding navigation items for certain users by setting the Type Permission's Navigate access. Since with this approach, the Navigate access can be granted only for a certain type, the following scenarios are not supported:

1. It is necessary to hide a DashboardView.
2. There are several navigation items for a certain type, and it is required to hide a part of them.
3. It is necessary to hide a navigation item that is not associated with a certain View (e.g., a navigation group).


This article demonstrates how to extend the security role class with the HiddenNavigationItems property allowing hiding navigation items by their ID.

Steps to implement:

1. Implement a custom permission type - NavigationItemPermission - that can be used to check access permissions for a certain navigation item by its ID.
2. Implement a custom permission request - NavigationItemPermissionRequest - that will be sent to check whether the current user has access to a certain navigation item.
3. Implement a custom permission request processor - NavigationItemPermissionRequestProcessor - that determines whether the current user has permissions for the received permission request.
4. Register the permission request processor in the application by handling the SecurityStrategy.CustomizeRequestProcessors event in the Program.cs and Global.asax.cs files.
5. Implement a custom role with the HiddenNavigationItems property. Override the role's GetPermissionsCore method to create NavigationPermission instances based on the value of the HiddenNavigationItems property.
6. Implement a ShowNavigationItemController's descendant - CustomShowNavigationItemController - and override its SynchItemWithSecurity method to deactivate navigation items prohibited by the CustomSecurityRole.HiddenNavigationItems property.

How to implement CRUD operations with a DataSource

This example demonstrates how to implement CRUD operations with a DataSource that obtains data from a remote Rest service. The DataSource object does not implement CRUD operations out-of-the-box. We can do this using jQuery.ajax. It is also necessary to call the DataSource.load method to "inform" your widget that it is necessary to reload its content.

Thank you for the code.But the problem is that it is related to data that is retrieved through the service.I tried getting my data retrieved from my json file but then it shows errors.
So ,if you could give me a stand alone project ,including the data base I would be able to understand very clearly.

Implement a custom drop-down editor with TreeView as PopupContent

April 12, 2011, 1:42 am
$

0

Show how to implement a custom ComboBoxEdit with TreeView as a PopupContent and use it inside DXGrid as a custom column.


Update (version 13.1):


We've modified this code example by using the DevExpress control version 13.1. There is no need to create custom classes to resolve this problem.

You can accomplish this task by using the Grid control in the TreeView mode as a popup content template of the LookUpEdit control.

This way is more efficient and clear than the way used in this example for old versions of DevExpress controls.


Here is a snippet of the markup file:

[XAML]
<dxg:LookUpEditName="lookUpEdit"VerticalAlignment="Top"Width="350"Margin="50,37,67,0"DisplayMember="Name"><dxg:LookUpEdit.PopupContentTemplate><ControlTemplate><dxg:GridControlx:Name="PART_GridControl"AutoGenerateColumns="AddNew"><dxg:GridControl.Columns><dxg:GridColumnFieldName="Name"Header="Employee Name"/><dxg:GridColumnFieldName="Position"/><dxg:GridColumnFieldName="Department"/></dxg:GridControl.Columns><dxg:GridControl.View><dxg:TreeListViewName="treeListView1"AutoWidth="True"KeyFieldName="ID"ParentFieldName="ParentID"TreeDerivationMode="Selfreference"/></dxg:GridControl.View></dxg:GridControl></ControlTemplate></dxg:LookUpEdit.PopupContentTemplate></dxg:LookUpEdit>

Added By: JSB at: 12/18/2013 1:24:24 PM    

Hi,

Thanks for the update, but while using this with the latest version (13.2), i am unable to hide the columns specified via xaml only approach.

As an example in the above code, even after changing the AutoGenerateColumns from "AddNew" to "None" for GridControl and setting dxg:GridColumns (Position and Department) with Visible="None", those columns are still being shown in the TreeView.

But i can hide the columns by implementing AutoGeneratedColumns Event of GridControl and handling it in the code behind by setting those columns' Visible Property to false.

Am i missing something or this is the only way to do it?

Also is there a way to allow selection of only leaves and parent nodes cannot be selected, as it was possible with earlier approach

How to create a movable legend at runtime

Question Comments
Added By: Dimitar Tomov Dimitrov at: 6/12/2014 6:50:57 AM    

Hi DevExpress team,

I would like to point you to a small issue with this example and share a solution.
However the example works as expected, it breaks down the scrolling by mouse behavior of the chart. The cause is that the mouse is captured in the chart_MouseLeftButtonDown event handler without checking if we are over the legend or not.

The solution is very simple - Just check the state of the isDragging variable before capturing the mouse. If isDragging is true, than we are over the legend and we can capture the mouse. Otherwise we shouldn't capture the mouse in order to allow the chart to be scrolled by mouse.

Regards,

Dimitar Dimitrov

How to set Country combobox as checked combobox?

Added By: Mr Price Group Ltd Mr Price Group Ltd at: 3/17/2014 3:18:09 AM    

After struggling to apply this to my project, I think what needs to be stressed here is the fact that, apart from the @model reference, the combobox and only the combobox must be in the partial view so that the framework knows what to update.

I had a <div> tag surrounding the a label element and the combobox and the callback was displaying a popup message with my results. After moving those out of the partial view, the combobox updated correctly.

Hi,

I think this sample needs to be reviewed !
There's a problem with it. If You'd put a breakpoint in Product (line 44 or line 54) - the UpdateTotals.. method - get executed when I click "Reload" in the ListView.

Basically - if I have N+1 records in the ListView, and click refresh, it would go and fetch the details for all child records, and recalculate the "Total" on the master record. Though it should NOT.

That kinda the point of having it persistent right ? So it would get recalculated only when one updates the Details collection !

The size of each GridView's element is calculated by the GridViewInfo class.

This method is hidden for IntelliSence, but is public and can be called from external code.

How to export a web chart on a client side

This example demonstrates how to use client-side events to export a WebChartControl to PDF on a client side. To do this, it is necessary to do the following:
1. Set the WebChartControl.ClientInstanceName property to some value (e.g. "chart1");
2. Add two ASPxButton controls to a web page, and set their AutoPostBack properties to False;
3. Handle their client-side Click event as "chart1.SaveToWindow('pdf');" or "chart1.SaveToDisk('pdf');".

NOTE: Since exporting a chart to PDF is based upon the XtraPrinting Library, don't forget to add a reference to the DevExpress.XtraPrinting assembly into your project's References list.

This example illustrates how to define a master-detail GridView located on different PageControl TabPages.

The main implementation details:

- Define both grids in separate PartialView files. See the KA20010: Why can the alert message with the HTML/JavaScript/CSS content appear when using callback-aware extensions? KB Article for more information;
- Handle the master grid's client-side FocusedRowChanged event;
- Perform a custom callback of the detail grid via the client-side ASPxClientGridView.PerformCallback method;
- Handle the detail grid's client-side BeginCallback event;
- Pass the required data (for example, the master grid's data FocusedRow keyValue / visibleIndex) as a parameter. See the Passing Values to a Controller Action through Callbacks help topic for more information;
- Handle the detail grid's CallbackRouteValues.Action method, retrieve the passed parameter and initialize the Model object according to this data.

Hello, thank you for this solution, however I have a question. When I undock customDockPanel2 - the one whose caption is being hidden and afterwards I hide its caption,  the panel looks quite ugly as there is no top border. So the floating panel has borders from 3 sides, however from the top, there is nothing.  Is there a workaround to paint to the top the same border as from the other 3 sides,when the caption bar is hidden?
