Obtaining Selected Records in Developer Express XtraGrid

Applies to TestComplete 15.65, last modified on July 17, 2024

When testing your application with the XtraGrid control, you may need to select multiple records in a grid. Then, you may need to determine which records are selected in the grid in order to process them a certain way. You can work with the selected records using the following native properties and methods of the grid’s view:

  • viewObj.GetSelectedRows - Returns an array containing the indexes of the rows (cards) selected in the given view. Note that the returned array is a .NET object, so you cannot access its elements using simple indexing. You should use the object’s internal properties or methods instead.
  • viewObj.SelectedRowsCount - Returns the number of rows (cards) currently selected in the given view.
Note: These properties are available to TestComplete only if the .NET Application Support plugin is installed and enabled.
Example

Below is an example that demonstrates how you can work with selections in the XtraGrid control.

The example works with the GridTutorials application.

How to get the application

View example description

JavaScript

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

  // Select a range of rows
  SelectRange (Grid, 3, 21);

  // Iterate through the selected rows
  let RowIndexes = GetSelectedRowIndexes (Grid, null);
  for (let i=0; i<RowIndexes.length; i++)
    Log.Message (RowIndexes[i] + ": " + Grid.wValue(RowIndexes[i], "Order ID"));
}

// Selects the specified range of rows
function SelectRange (ActiveViewObj, StartRowIndex, EndRowIndex)
{
  // Select the first row of the range
  ActiveViewObj.ClickRowIndicator (StartRowIndex);
  // Extend the selection
  ActiveViewObj.ClickRowIndicator (EndRowIndex, skShift);
}

// Returns an array of selected rows' indexes
function GetSelectedRowIndexes (Grid, View)
{
  // Get the grid view object, if it is not specified
  if (strictEqual(View, null))
    View = Grid.MainView;

  // Get an array of selected rows' indexes
  let SelectedRows = View.GetSelectedRows();

  // Convert a .NET array to a JavaScript array
  let arr = new Array (View.SelectedRowsCount);
  for (let i=0; i<View.SelectedRowsCount; i++)
    arr[i] = SelectedRows.Get(i);

  return arr;
}
