Applies to TestComplete 14.10, last modified on May 13, 2019

This topic describes the various approaches that you can use to obtain and change values stored in the XtraGrid cells. The explanation applies to all XtraGrid layouts -- grid, card, banded and others.

Note that before getting or setting the cell value, you need to know in which row (card) and column (card field) the desired cell resides. For example, you can search for the record containing the desired cell within the grid.

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.

Obtaining Cell Values

To get the value from a particular grid cell, you can use the wValue property of the DevExpressXtraGrid or DevExpressXtraGridView objects. The wValue property of a DevExpressXtraGrid provides access to a cell’s value of the main data view, while the property of a DevExpressXtraGridView relates to the cells of a corresponding child data view. Note that this property returns the “native” .NET object corresponding to the cell value. Some “simple” values, for example, Integer, Boolean and others, are OLE-compatible and thus can be used in scripts directly. Others, such as String, Decimal, DateTime and enumeration values are made OLE-compatible via the OleValue property added to these objects by TestComplete. To work with complex object values, use their internal properties and methods.

Alternatively, you can get the grid cell values using internal methods of the view in which the cell resides:

  • viewObj.GetRowCellValue (RowIndexColumnObj): Returns the value of a cell specified by the row (card) index and the column object.
  • viewObj.GetRowCellValue_2 (RowIndexFieldName): Returns the value of a cell specified by the row (card) index and the column’s dataset field name.

In certain cases, the cell value may significantly differ from the actual text displayed in the cell. For example, the XtraGrid control may display values with a special formatting applied: date values can be displayed as “Tuesday, March 19, 2007” instead of “3/19/2007”, currency values as $123,456.78 instead of 123456.78, and so on. Another example is a grid that uses a lookup (foreign key) combo box that stores values of one dataset field, but displays the corresponding values of another field. For example, the column may hold values of the EmployeeID dataset field but, for usability purposes, display values of the EmployeeName field corresponding to the given EmployeeID value.

In the cases described above, you will most likely want to get the actual text displayed in grid cells rather than the cell values. The following methods of the grid’s view lets you obtain the cell text:

  • viewObj.GetRowCellDisplayText (RowIndexColumnObj): Returns the text in the cell specified by the row (card) index and the column object.
  • viewObj.GetRowCellDisplayText_2 (RowIndexFieldName): Returns the text in the cell specified by the row (card) index and the column’ dataset field name.

Setting Cell Values

There are two general approaches for modifying XtraGrid cell values:

  • Simulating the user actions over the cell’s in-place editor, for example, “typing” the new value into the cell.
  • Assigning the new value using the wValue property or internal methods and properties of the XtraGrid control.

Detailed information and script samples for both approaches are provided below. These approaches work well for most types of in-place editors. However, if the XtraGrid control in the tested application uses specific in-place editors (for example, check boxes, text boxes with embedded buttons, lookup editors and others), you may need to work with them in a custom way. For more information on how to work with specific editors, see Working With Specific In-place Editors in Developer Express XtraGrid.

Simulating User Input

To modify grid cell values, you can input the new values directly in grid cells. Note that before that, you should locate the row (card) and column (card field) in which the cell resides. For example, you can search for the row (card) containing the cell with the desired value. After you have determined the cell position, you should select the desired cell within the grid and activate the cell’s in-place editor. When the cell’s is in the edit mode, you can “type” the desired value into it using the Keys action applied to the grid control.

Below is an example that illustrates how you can do it. It “types” new values into grid’s edit boxes.

Assigning the New Value Programmatically

Another way to modify grid cell values is to use the wValue property of the DevExpressXtraGrid or DevExpressXtraGridView objects. This property is read-write, so it can be used to obtain grid cell values as well as to change them:

JavaScript

function Main ()
{
  var p, frmMain, Grid;

  // Obtain the application process and its main form
  p = Sys.Process("GridTutorials");
  frmMain = p.WinFormsObject("frmMain");
  frmMain.Activate();
  // Select the "Multi Editors" demo
  frmMain.WinFormsObject("gcNavigations").WinFormsObject("listBoxControl1").SelectedItem = "Multi Editors";
  // Obtain the grid object
  Grid = frmMain.WinFormsObject("pcMain").WinFormsObject("gcContainer").WinFormsObject("Form1").WinFormsObject("gridControl1");

  // Change column values
  Grid.$set("wValue", 0, "Product1", "Chang");
  Grid.$set("wValue", 1, "Product1", "1"); // CategoryID for "Beverages"
  Grid.$set("wValue", 2, "Product1", "Exotic Liquids");
  Grid.$set("wValue", 3, "Product1", "24 - 12 oz bottles");
  Grid.$set("wValue", 4, "Product1", 15.2);
  Grid.$set("wValue", 5, "Product1", 17);
  Grid.$set("wValue", 6, "Product1", false);
  Grid.$set("wValue", 7, "Product1", "3/19/2007");
  Grid.$set("wValue", 8, "Product1", 90);
}

JScript

function Main ()
{
  var p, frmMain, Grid;

  // Obtain the application process and its main form
  p = Sys.Process("GridTutorials");
  frmMain = p.WinFormsObject("frmMain");
  frmMain.Activate();
  // Select the "Multi Editors" demo
  frmMain.WinFormsObject("gcNavigations").WinFormsObject("listBoxControl1").SelectedItem = "Multi Editors";
  // Obtain the grid object
  Grid = frmMain.WinFormsObject("pcMain").WinFormsObject("gcContainer").WinFormsObject("Form1").WinFormsObject("gridControl1");

  // Change column values
  Grid.wValue (0, "Product1") = "Chang";
  Grid.wValue (1, "Product1") = "1"; // CategoryID for "Beverages"
  Grid.wValue (2, "Product1") = "Exotic Liquids";
  Grid.wValue (3, "Product1") = "24 - 12 oz bottles";
  Grid.wValue (4, "Product1") = 15.2;
  Grid.wValue (5, "Product1") = 17;
  Grid.wValue (6, "Product1") = false;
  Grid.wValue (7, "Product1") = "3/19/2007";

  Grid["wValue"](7, "Product1") = "3/19/2007";
  Grid["wValue"](8, "Product1") = 90;
}

It is also possible to change the value of a particular grid cell internal methods of the grid’ view where the cell resides:

  • viewObj.SetRowCellValue (RowIndexColumnObjValue): Assigns Value to the cell specified by the row index and the column object.
  • viewObj.SetRowCellValue_2 (RowIndexFieldNameValue): Assigns Value to the cell specified by the row index and the column’s dataset field name.

Below is an example that demonstrates how to use these methods in scripts.
