This is an example for article How to refer to a client-side control within a UserControl. There is a UserControl with an ASPxPopupControl control. Two instances of the UserControl are put on a page. Each UserControl instance deals with its own popup control. Note the dynamically generated handler for the button's client-side Click event in WebUserControl.ascx code behind.

Trying this with an ASPxRadioButton and getting "Databinding expressions are only supported on objects that have a DataBinding event.  DevExpress.Web.CheckEditClientSideEvents does not have a DataBinding event."

Any ideas?

This works for controls where you can bind the function. However it not explain how to bind the javascript function on grid callbacks.

If you have this situation, I have no idea how to adapt openComisarioDetalle:

<script id="dxss_personaluploaderscript" type="text/javascript">
function gridComisionadosCustomButtonClick(s, e) {
gridcomisarios.GetRowValues(e.visibleIndex, "idrecord;name;surname", openComisarioDetalle);
}
function openComisarioDetalle(values) {
//some code here
}
</script>

<dx:ASPxGridView ID="gridcomisarios" runat="server" AutoGenerateColumns="False"
                   Width="100%" EnableTheming="True" ClientInstanceName="gridcomisarios" EnableViewState="False" Cursor="pointer">
                   <ClientSideEvents CustomButtonClick="function(s, e) { gridComisionadosCustomButtonClick(s, e); }" />

How to specify custom background for DXEditors

December 31, 2000, 4:00 pm
$

In our themes, the Control.BackgroundProperty is defined by several elements with different colors, gradients, margins, paddings and corner rounding. You can't specify this complex functionality with only the Control.BackgroundProperty property. You can implement your own template using the TextEditThemeKey key ({dxet:TextEditThemeKey ResourceKey=BorderTemplate}). Also, you need to bind to the Background property.

Question Comments
Added By: Drew Noakes at: 8/19/2015 3:58:07 AM    

Is it a problem that the control template's binding references TextEdit, yet is also used in DateEdit and ComboBoxEdit?

Change the Field Value Header appearance backcolor or draw it manually

January 10, 2011, 1:36 am
$

0

If UserLookAndFeel.Style is equal to Skin, the XtraPivotGrid control uses the Skins technology to draw its content. With this approach, all headers are drawn using a specific bitmap provided by a corresponding skin element. The appearance back color settings have no effect in this instance. So, if you want to draw a field header using a custom color, you should draw the field header manually via the PivotGridControl.CustomDrawFieldValue event.

The DrawIndicator method can throw exceptions in versions 15.1.3 - 15.1.5. We have fixed this issue in the context of the DrawIndicator method call throws an exception after updating to 15.1.5 ticket.

I am trying to follow this example.  However, in my application, after I add the MultiLineButtonEdit Code and Bitmap to my project, the following happens:

1. The ellipsis do not show on the control in the designer like the example does.
2. The graphic does not show in the RepositoryItem toolbox dropdown when selecting the columnedit.

Other than those two cosmetic issues, the button does function.  Any idea on what I can do to fix these two minor issues?

This example demonstrates how to allow a user to copy dragged rows on the modifier key press. A custom attached property is used to determine whether or not the user wants to copy rows. You can adjust this property in the PreviewKeyDown and PreviewKeyUp event handlers. Then, use it in the DragElementTemplate to modify the drag element appearance accordingly. At last, replace data objects within the DraggedRows collection in the Drop event handler with newly created items.

This example demonstrates how to use the DashboardDesigner.DataSourceWizardCustomization to replace the default pages of the data source wizard with custom ones:

[C#]
dashboardDesigner1.DataSourceWizardCustomization=newDataSourceWizardCustomization();

 

We use following code to skip first page which allows selecting the data source type, and specify custom a wizard page that allows selecting one of the predefined connections. This custom page does not allow establishing a new connection:

[C#]
publicclassDataSourceWizardCustomization:IDashboardDataSourceWizardCustomization{publicvoidCustomizeDataSourceWizard(IWizardCustomization<DashboardDataSourceModel>customization){customization.StartPage=typeof(ChooseConnectionPage<DashboardDataSourceModel>);customization.Model.DataSourceType=DashboardDataSourceType.Xpo;customization.RegisterPageView<IChooseConnectionPageView,CustomChooseConnectionPageView>();}}

 

To specify default connections in code behind, use the DashboardDesigner.CustomDataConnections Property.

Hi,

I run this example. first no references is known and I add all again and then this error appear when I compile it:
'WizardCustomizationExample1.DataSourceWizardCustomization' does not implement interface member 'DevExpress.DashboardWin.ServiceModel.IDashboardDataSourceWizardCustomization.CustomizeDataSourceWizzard(DevExpress.DataAccess.UI.Wizard.IWizardCustomization<DevExpress.DashboardCommon.DashboardDataSourceModel>)'

The error is from DataSourceWizardCustomization1.cs line 49 column 18

how can I resolve this error?

Added By: Constant (DevExpress Support) at: 7/30/2015 12:39:46 AM    

The problem likely appears because you use the Dashboard Suite version, which does not support this functionality. This interface and other required members were introduced only in version 15.1.5. If you use an older version, it is necessary to upgrade it to use this functionality.

This example demonstrates how to implement a custom IConnectionStorageService and use it instead of the default one in the data source wizard. This service implementation allows only getting connection parameters from the DashboardDesigner.CustomDataConnection collection. To load the custom service instead of the default one, execute the following code:

This example demonstrates how add two custom items to the Ribbon toolbar of the Banded End-User Report Designer. These custom items allows you to manage the designer's side panel's and toolbox's visibility.


To customize the WPF Banded End-User Report Designer's Ribbon toolbar use it's RibbonTemplate: Get the original RibbonTemplate XAML code from our source files, add it to your application, customize it according to your requirements and assign it to the ReportDesigner.RibbonTemplate property.

In this example, I have added the RibbonPageGroup with two BarCheckItems to the Report Designer's RibbonTemplate and bound these items to the CustomizedRibbonCommands class properties. This class object (CustomRibbonCommands) is assigned to the MainWindow and realizes the side panel and toolbox showing/hiding logic:

[XAML]
<DataTemplatex:Key="CustomizedRibbonTemplate"><dxr:RibbonControl...><dxr:RibbonDefaultPageCategory><dxr:RibbonPageCaption="Report Designer">

1) Some of my columns are binded to another tables in a datasource with lookup edit, where it gets its values. While copying and pasting a row, there is a FormatException, because columns valuemember is int, display member is string. How can it be solved?

2) It also throws exception ArgumentException, when pasting empty cell of type DateTime. It is not leaving empty Datetime cell as empty in pasted row, says "String was not recognized as a valid Datetime.."

Thank you very much!
