Accessing Views in Developer Express XtraGrid

Applies to TestComplete 15.69, last modified on November 13, 2024

The XtraGrid control can display data of multiple nested tables. The data of each child table as well as the parent table is displayed in a separate view. A view is an object that holds information about the data displayed in it, the number of rows and columns, appearance and behavior settings. Methods and properties of the DevExpressXtraGrid object that is used to work with XtraGrid controls from TestComplete scripts, as well as many custom examples in this section require that you specify the view under which the operation is applied. This topic explains how you can access the XtraGrid views.

To perform these actions, TestComplete should have access to internal objects, properties and methods of the XtraGrid control. For this purpose, the .NET Application Support and Developer Express Control Support plugins must be installed and enabled. The latter lets you work with the XtraGrid control using methods and properties of the DevExpressXtraGrid object. Without this plugin, you will not be able to work with XtraGrid controls using their internal methods and properties.

When testing Developer Express XtraGrid controls, use specific methods and properties of the corresponding DevExpressXtraGrid object. You can call these methods and properties from your keyword tests, as well as from scripts. This topic describes how to work with an object’s properties and methods from your scripts. However, when testing an XtraGrid control from your keyword test, you can use the same methods and properties calling them from keyword test operations. For more information, see Keyword Tests Basic Operations.

Accessing Views Using the DevExpressXtraGrid.wChildView Property

Methods and properties of the DevExpressXtraGrid object let you work with data displayed in the top-level grid view. To access child views and work with child data, you can use the wChildView property. This property returns the DevExpressXtraGridView object that represents the specified child view. Similarly, you can access a grand-child view by using the wChildView property applied to a child view object, and so on. The wChildViewCount property lets you determine the number of child views for a particular grid row. You can use this property, for example, if you need to iterate through child views.

Note: The XtraGrid control architecture only allows child views to exist when they are displayed in the grid, that is, when their parent rows are expanded. When you access a child view using the wChildView property, TestComplete automatically expands the view’s parent row and selects this view, so that you do not have to perform any additional actions to expand the parent row.
Example

Below is an example that illustrates how you can work with several grid views.

The example works with the GridMainDemo application.

Accessing Views Using XtraGrid’s Internal Properties and Methods

Sometimes you may need to get “native” .NET objects that represent a particular grid view. For example, you may want to perform specific actions or checks using internal methods and properties of the XtraGrid control.

The XtraGrid control provides special properties that let you quickly access specific views:

  • MainView provides access to the topmost grid view.
  • FocusedView provides access to the currently focused view. You can use this property, for example, to determine or set the focused view in a grid that displays data of multiple nested tables.
  • DefaultView returns the currently maximized grid view (it can be either MainView or a child view).

If the grid displays data of one table only, the FocusedView and DefaultView properties return the same view as the MainView property.

The following code snippet demonstrates how you can obtain the number of rows and columns in a currently focused grid view:

JavaScript, JScript
Python
VBScript
DelphiScript
C++Script, C#Script
Copy Code

JavaScript, JScript

function Test ()
{
  var Grid, View;

  // Obtain the grid object
  ...
  // Obtain the currently focused grid view
  View = Grid.FocusedView;

  Log.Message ("The grid has " + View.RowCount + " rows and " + View.Columns.Count + " columns.");
}

Python

def Test ():

  # Obtain the grid object
  ...
  # Obtain the currently focused grid view
  View = Grid.FocusedView

  Log.Message ("The grid has " + View.RowCount + " rows and " + View.Columns.Count + " columns.")

VBScript

Sub Test
  Dim Grid, View

   ' Obtain the grid object
  ...
  ' Obtain the currently focused grid view
  Set View = Grid.FocusedView

  Call Log.Message ("The grid has " & View.RowCount & " rows and " & View.Columns.Count & " columns.")
End Sub

DelphiScript

procedure Test;
var Grid, View : OleVariant;
begin
  // Obtain the grid object
  ...
  // Obtain the currently focused grid view
  View := Grid.FocusedView;

  Log.Message ('The grid has ' + aqConvert.VarToStr(View.RowCount) + ' rows and ' + aqConvert.VarToStr(View.Columns.Count) + ' columns.');
end;

C++Script, C#Script

function Test ()
{
  var Grid, View;

  // Obtain the grid object
  ...
  // Obtain the currently focused grid view
  View = Grid["FocusedView"];

  Log["Message"]("The grid has " + View["RowCount"] + " rows and " + View["Columns"]["Count"] + " columns.");
}

If the grid displays hierarchical data, you will need to work with the data displayed in the top-level view as well as in its child views. To obtain a “native” child view object, you need to create a script that performs the following actions:

  • Expands the view’s parent row. This is needed, because child views in the XtraGrid control only exist when they are displayed in the grid. To learn how you can expand XtraGrid rows, see Expanding and Collapsing Rows in Developer Express XtraGrid.
  • Selects the desired child view, among child views of its parent row. Due to the above-mentioned specific, if the row has several child views, you need to switch to the desired child view in order to be able to access it. You can select a child view by its index (zero-based) using the following SetMasterRowExpandedEx method of the parent view object:
    viewObj.SetMasterRowExpandedEx(RowIndex, ChildViewIndex, true)
  • Obtains the desired child view. For this purpose, use the GetVisibleDetailView method of the parent view object. It returns the currently displayed child view for the specified row:
    viewObj.GetVisibleDetailView(RowIndex)
Example

Below is an example that demonstrates how you can access and work with views in the XtraGrid control using its internal properties and methods.

The example works with the GridMainDemo application.
