Activating In-place Editors in Developer Express QuantumGrid

Applies to TestComplete 15.40, last modified on March 25, 2022

The QuantumGrid control lets users change data directly within grid cells. This topic explains how you can activate an in-place editor from scripts.

In order for TestComplete to be able to perform these actions, the following conditions must be met: Note also, that the compiler can exclude methods and properties that are not called in the application’s source code from the application’s binary code, so these methods and properties are unavailable to TestComplete (see Object Properties, Fields and Methods That Are Unavailable to TestComplete). To solve the problem, make sure that the desired methods and properties are used in the application’s source code. For instance, you can add a virtual method to your application that calls the desired methods and properties (the compiler does not exclude virtual methods).

When testing Developer Express QuantumGrid controls, use specific methods and properties of the corresponding DevExpressQuantumGrid 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 a QuantumGrid 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.

Genaral Notes

Before activating the cell’s in-place editor, you need to locate the desired cell within the grid and select it. To search for the desired row, you can use the methods described here: Searching for Records in Developer Express QuantumGrid. The Selecting Cells in Developer Express QuantumGrid topic explains how you can select the desired grid cell.

Activating In-place Editors With Keyboard Shortcuts

The focused cell’s in-place editor can be activated upon pressing the F2 key. You can simulate this key press using the Keys action applied to the TcxGrid object. The following code demonstrates how you can do this:

Example

View description

JavaScript

function Main()
{
var p, Grid, View;
var ParentRowIndex, ParentView, RowIndex, ColumnId, ChildViewId;
  
  ParentRowIndex=2;
  ParentView=0;
  RowIndex=4;
  ColumnId=2;
  ChildViewId=1;
  
  // Obtain the application process
  p = Sys.Process("MySampleApp");
  // Obtain the grid object
  Grid = p.VCLObject("FormName").VCLObject("GridName");
  // Obtain child view
  View = Grid.wChildLevel(ParentRowIndex, ParentView);
  
  // Activate in-place editor
  ActivateCellInplaceEditor(Grid, View, RowIndex, ColumnId, ChildViewId);
}

// Activate in-place editor
function ActivateCellInplaceEditor(grid, view, rowIndex, columnId, childViewId)
{
  if (strictEqual(view, null))
      ActiveView = grid;
    else
      ActiveView = view;

  // Select the cell
  ActiveView.ClickCell(rowIndex, columnId, childViewId);
  // Simulate keystroke
  grid.Keys("[F2]");
}

JScript

function Main()
{
var p, Grid, View;
var ParentRowIndex, ParentView, RowIndex, ColumnId, ChildViewId;
  
  ParentRowIndex=2;
  ParentView=0;
  RowIndex=4;
  ColumnId=2;
  ChildViewId=1;
  
  // Obtain the application process
  p = Sys.Process("MySampleApp");
  // Obtain the grid object
  Grid = p.VCLObject("FormName").VCLObject("GridName");
  // Obtain child view
  View = Grid.wChildLevel(ParentRowIndex, ParentView);
  
  // Activate in-place editor
  ActivateCellInplaceEditor(Grid, View, RowIndex, ColumnId, ChildViewId);
}

// Activate in-place editor
function ActivateCellInplaceEditor(grid, view, rowIndex, columnId, childViewId)
{
  if (view == null)
      ActiveView = grid;
    else
      ActiveView = view;

  // Select the cell
  ActiveView.ClickCell(rowIndex, columnId, childViewId);
  // Simulate keystroke
  grid.Keys("[F2]");
}

Activating In-place Editors Using TcxGrid Internal Methods

You can also activate an in-place editor by calling the Controller.EditingController.ShowEdit method of the view object that is used by the TcxGrid object (TcxGrid is the class name of QuantumGrid controls). The ShowEdit method can use one or several parameters that specify various options. For more information on these parameters, please see the QuantumGrid documentation. In our example, we will only pass one parameter to this method - null (JavaScript, JScript, C#Script, C++Script), None (Python), 0 (VBScript) or nil (DelphiScript). The following code demonstrates how to activate an in-place editor by calling the ShowEdit method.

Example

View description

JavaScript

function Main()
{
  var p, Grid, r;

  p = Sys.Process("MySampleApp");
  Grid = p.VCLObject("FormName").VCLObject("GridName");
  // Set Grid = GetGrid1
  
  // Activate in-place editor
  ActivateCellInplaceEditor(Grid, null, 4, 3);
}

// Activate in-place editor
function ActivateCellInplaceEditor(grid, view, rowIndex, columnId)
{
  // Select the view object
  if (strictEqual(view, null))
    view = grid.ActiveView;
  // Select the cell
  SelectGridCell(grid, view, rowIndex, columnId);
  // Activate in-place editor
  view.Controller.EditingController.ShowEdit(null);
}

// Select grid cell
function SelectGridCell(grid, view, rowIndex, columnId)
{
  // Obtain the view object
  if (isNull(view))
    view = grid.ActiveView;
  // Select the column
  view.Controller.FocusedColumn = GetColumn(grid, view, columnId);
  // Select the row
  view.Controller.FocusedRowIndex = rowIndex;
}

// Obtain column object
function GetColumn(grid, view, columnId)
{
  
  // Get the view
  if (isNull(view))
    view = grid.ActiveView;
  
  // Check type of the columnId parameter
  if (equal(aqObject.GetVarType(columnId), varOleStr))
  {
    // If columnId is a string,
    // then search for column by its caption
    for (let i = 0; i < view.ColumnCount; i++)
      if (equal(view.Columns(i).Caption, columnId))
        return view.Columns(i);
  }
  else
  {
    // If columnId is an integer,
    // then search for column by its index
    for (let i = 0; i < view.ColumnCount; i++)
      if (equal(view.Columns(i).VisibleIndex, columnId))
        return view.Columns(i);
  }
}

Closing In-place Editors

To finish editing the QuantumGrid cell value and save any changes made, the user should press the Enter key, or select another grid cell. You can simulate the Enter keypress using the Keys action.

The following code snippet contains the CloseCellEditor routine that can be used to save changes made to a grid cell. The Grid parameter of this routine specifies the grid control under which the action is performed:

JavaScript, JScript

function CloseCellEditor (grid)
{
  grid.Keys ("[Enter]");
}

Python

def CloseCellEditor (grid):
  grid.Keys ("[Enter]")

VBScript

Sub CloseCellEditor (grid)
  grid.Keys "[Enter]"
End Sub

DelphiScript

procedure CloseCellEditor (grid);
begin
  grid.Keys ('[Enter]');
end;

C++Script, C#Script

function CloseCellEditor (grid)
{
  grid["Keys"] ("[Enter]");
}

You may also need to cancel the editing and discard any changes made to the cell. This happens when the user presses Esc. To simulate the Esc key press, use the Keys action. The CancelEditing routine in the code snippet below demonstrates how to do this:

JavaScript, JScript

function CancelEditing (grid)
{
  grid.Keys ("[Esc]");
}

Python

def CancelEditing (grid):
  grid.Keys ("[Esc]")

VBScript

Sub CancelEditing (grid)
  grid.Keys "[Esc]"
End Sub

DelphiScript

procedure CancelEditing (grid);
begin
  grid.Keys ('[Esc]');
end;

C++Script, C#Script

function CancelEditing (grid)
{
  grid["Keys"] ("[Esc]");
}
