This example illustrates how to pass the ASPxGridView.FilterExpression property value between the Controller, View and client-side parts of an application. In particular, we can store custom filters in a separate ListBox extension.

The main implementation details are:
- Pass the current FilterExpression value to the client side by handling the GridViewSettings.CustomJSProperties event (you can find a similar technique in the E5121 - GridView - How to implement data editing with hidden column code example).
- Pass the required FilterExpression value to the server side by calling the MVCxClientGridView.PerformCallback(Object) method. Alternatively, you can use the approach from the Passing Values to a Controller Action through Callbacks help section (e.g., see T146962 - GridView - How to track ClientLayout with a separate ListBox).
- Put the passed value to the ViewData dictionary to be able to intercept it in the View context and apply filter to GridView by handling the DataBound event.

≫ Next: How to make PopupControl stay open after submitting a form using Ajax.BeginForm

≪ Previous: GridView - How to access/modify FilterExpression on the controller and save/load custom filters

This example illustrates several approaches to display the PopupControl extension after performing server-side processing. In the simplest scenario we use the PopupControlSettingsBase.ShowOnPageLoad option to display the popup control initially. Note that we can pass any dynamic settings or content for the popup control through the ViewData dictionary. To show the popup control on the client side, we can call the ASPxClientPopupControlBase.Show() method. In addition we can use the ASPxClientPopupControlBase.SetContentHtml method to modify popup content on the client side.

Finally, there is a scenario when the popup control should be displayed after a callback of some other extension. Please review the T159638 - GridView - How to show a message after CRUD operations code example, where we have illustrated how this can be implemented.

≫ Next: How to implement a custom range filter using ASPxTrackBar in ASPxGridView

≪ Previous: How to make PopupControl stay open after submitting a form using Ajax.BeginForm

This example demonstrates how you can integrate the Web Report Designer into your web application. The application contains a simple report catalog, allowing you to add, delete, and edit reports whose layout data is stored in a custom data storage (i.e., an MS SQL database).

Additionally, this example demonstrates how you can add custom commands to the report designer menu at runtime to provide better integration with your application. In the example, the custom Save&Close menu command is introduced, which redirects you to the catalog page after saving the report.

Important note: Starting with version 15.2, the ReportStorageWebExtension is used to manage the reports storage for the Web Report Designer instead of the controller actions.

≪ Previous: ASPxGridView - How to implement select/unselect for all rows in a group row

Since GridViewCommandColumn holds the command/interactive visual elements (but not any column's data), clicking its header does not perform any data shaping operation (such as sorting). If you need to perform data sorting based on the row's selection state (for instance, always display selected rows on top), consider implementing custom data sorting:

- Set each column's Settings.SortMode property to Custom.
- Handle the ASPxGridView.CustomColumnSort event.
- If both rows that should be compared have the same selection state, set the EventArgs e.Handled property to False in order to apply the default data comparing/sorting rules.
- If not, treat a selected row as a "stronger" one using the EventArgs e.Result property.

≪ Previous: TreeList - How to move nodes using a context menu

The ArcScale element has the Ranges property, providing access to the collection of custom ranges. You can populate this collection with instances of the ArcScaleRangeWeb class. This class has the following properties:

The AppearanceRange property provides the capability to define the BorderColor, BorderWidth and ContentColor of the ArcScaleRangeWeb.
The StartValue and EndValue properties allow you to set coordinates of the start and end points of the ArcScaleRangeWeb. These coordinates depend on the ArcScaleComponent.MinValue and ArcScaleComponent.MaxValue properties. Suppose, the ArcScaleComponent.MinValue = 30 and ArcScaleComponent.MaxValue = 90. For example, you can create two ArcScaleRangeWeb elements and set these StartValue and EndValue properties to the (30, 60) and (60, 90) to have two ranges, splitting the scale into two even parts.
The StartThickness and EndThickness properties allow you to define the thickness of the start and end of the ArcScaleRangeWeb.
The ShapeOffset property represents the spacing between the ArcScaleRangeWeb and the scale's edge. Setting negative values to this property moves the range to the center.

GridView - Batch Editing - A simple implementation of an EditItem template

June 5, 2014, 7:44 am

≫ Next: How to: Allow a user to select the authentication type at runtime

≪ Previous: GridView - A simple Batch Editing implementation

This example demonstrates how to create a custom editor inside column's DataItem template when GridView is in Batch Edit mode.

You can implement the EditItem template for a column by performing the following steps:

1. Specify column's EditItem template:

[C#]
       settings.Columns.Add(column=>       {           column.FieldName="C1";           column.SetEditItemTemplateContent(c=>           {               @Html.DevExpress().SpinEdit(spinSettings=>               {                   spinSettings.Name="C1spinEdit";                   spinSettings.Width=System.Web.UI.WebControls.Unit.Percentage(100);                   spinSettings.Properties.ClientSideEvents.KeyDown="C1spinEdit_KeyDown";                   spinSettings.Properties.ClientSideEvents.LostFocus="C1spinEdit_LostFocus";               }).Render();           });       });

2. Handle grid's client-side BatchEditStartEditing event to set the grid's cell values to the editor. It is possible to get the focused cell value using the e.rowValues property:

[JScript]
       function Grid_BatchEditStartEditing(s, e){           var productNameColumn = s.GetColumnByField("C1");           if(!e.rowValues.hasOwnProperty(productNameColumn.index))               return;           var cellInfo = e.rowValues[productNameColumn.index];            C1spinEdit.SetValue(cellInfo.value);           if(e.focusedColumn === productNameColumn)                C1spinEdit.SetFocus();       }

3. Handle the BatchEditEndEditing event to pass the value entered in the editor to the grid's cell:

[JScript]
function Grid_BatchEditEndEditing(s, e){var productNameColumn = s.GetColumnByField("C1");if(!e.rowValues.hasOwnProperty(productNameColumn.index))return;var cellInfo = e.rowValues[productNameColumn.index];
            cellInfo.value = C1spinEdit.GetValue();
            cellInfo.text = C1spinEdit.GetText();
            C1spinEdit.SetValue(null);}

4. The BatchEditRowValidating event allows validating the grid's cell based on the entered value:

[JScript]
function Grid_BatchEditRowValidating(s, e){var productNameColumn = s.GetColumnByField("C1");var cellValidationInfo = e.validationInfo[productNameColumn.index];if(!cellValidationInfo)return;var value = cellValidationInfo.value;if(!ASPxClientUtils.IsExists(value) || ASPxClientUtils.Trim(value) === ""){
                cellValidationInfo.isValid = false;
                cellValidationInfo.errorText = "C1 is required";}}

5. Finally, handle the editor's client-side KeyDown and LostFocus events to emulate the behavior of standard grid editors when an end-user uses a keyboard or mouse:

[JScript]
var preventEndEditOnLostFocus = false;function C1spinEdit_KeyDown(s, e){var keyCode = ASPxClientUtils.GetKeyCode(e.htmlEvent);if(keyCode !== 9 && keyCode !== 13)return;var moveActionName = e.htmlEvent.shiftKey ? "MoveFocusBackward" : "MoveFocusForward";if(grid.batchEditApi[moveActionName]()){
                ASPxClientUtils.PreventEventAndBubble(e.htmlEvent);
                preventEndEditOnLostFocus = true;}}function C1spinEdit_LostFocus(s, e){if(!preventEndEditOnLostFocus)
                grid.batchEditApi.EndEdit();
            preventEndEditOnLostFocus = false;}

Added By: David Lemieux at: 8/12/2015 10:09:43 AM

This probably does the trick for standalone lookup editors, but I have doubts about using this inside a grid. If my understanding of both the code below and the grid's mechanics is correct, a query will be issued for each and every cell for which such an editor is present. Therefore, if you have 20 records on screen with five columns each having such an editor, that's a hundred of connections opening, querying and closing right there. And EVEN with just ONE column, it will still be under-performing when it will be sorted, grouped or filtered. Even for the non-virtualized rows.

This needs a proper solution. Urgently.

Added By: Ivan (DevExpress Support) at: 8/13/2015 3:01:37 AM

David, you are correct. The editor we implemented in this example is not designed to be used inside GridControl.

≫ Next: How to disable the save confirmation dialog when closing a DetailView for a new object left untouched by an end-user

≪ Previous: How to implement a custom LookUpEdit supporting Server Mode

By default, unbound rows are not supported by PropertyGridControl. So, you can use VGridControl to display them.
However, PropertyGridControl allows you to provide custom property descriptors via the CustomDescriptors Event. So, you can implement the same functionality by creating a custom property descriptor that will store values for properties that do not present in the selected object.

This example demonstrates how this solution can be implemented.

≪ Previous: How to implement unbound rows in PropertyGridControl

Scenario
This example demonstrates how to implement the following behavior (which is default in Microsoft Outlook) in XAF Windows Forms applications:

- A user can create a new record, and when its detail form is opened he or she may close the form without entering any data (e.g., a new record was created by accident). In this case, the form can be closed without any save confirmation, because no user data needs to be saved.

- If a user enters some data into the form and then closes it, the save confirmation appears as expected not to lose entered data.

To implement it
Copy the WinSolution.Module.Win\SuppressConfirmationForNewObjectsDetailViewController.xx file into YourSolutionName.Module.Win project.

To test it
You can also run functional tests from the E2114.EasyTests\E2114.ets folder.

Popping out this message every time even nothing touched is annoying and I don't think anybody will like it.

This example illustrates how to move nodes using a context menu. It will be useful if your TreeList hierarchy is large and it's necessary to scroll a control/page to find the target node.

How to create persistent classes mapped to tables with a composite primary key at runtime

≪ Previous: TreeList - How to move nodes using a context menu

When you have a table with a composite key, a usual solution is to declare a structure for the key member as described in the How to create a persistent object for a database table with a compound key article. If the database schema is not known as design time, and you need to create persistent classes at runtime, there is no option to create a structure-like entity as this functionality is supported only for real types via Reflection. The example demonstrates how to create a custom XPCustomMemberInfo descendant with nested members support.

The OnSaving and OnDeleting method of the persistent objects can be overridden to log create/update/delete actions into a separate table. This example demonstrates the basic implementation of this feature.

Note: eXpressApp Framework have built-in module for Audit purposes. This example demonstrates how to use this module in non XAF application: How to use XAF Audit Trail module outside XAF.

Hello,

To process your recent post more efficiently, I created a separate ticket on your behalf: T159303: Audit application events. This ticket is currently in our processing queue. Our team will address it as soon as we have any updates.

Added By: Reinhold Erlacher at: 4/2/2016 11:57:49 AM Hello, could you help me to extend the sample to track changes in many-many associations. I'd like to get left and right classes and oids.
Thanks
Reinhold
