ChildDataByIndex Property

Applies to TestComplete 14.71, last modified on April 22, 2021

Description

A table row can have child data (do not confuse child data with child rows). This is the data displayed in additional log panels when you select the given table row. For example, in the case of the table in the Test Log pane of the generic script log, the child datasets for the table row are data that is displayed in the Details and Picture panels.

The ChildDataByIndex property returns the child dataset of the given table row. The dataset to obtain is specified by its index.

The total number of child datasets is specified by the LogDataScheme.ChildCount property.

Declaration

LogTableRowObj.ChildDataByIndex(Index)

Read-Only Property A LogTableData, TextLogData or PictureLogData object
LogTableRowObj An expression, variable or parameter that specifies a reference to a LogTableRow object
Index [in]    Required    Integer    

Applies To

The property is applied to the following object:

LogTableRow

Parameters

The property has the following parameter:

Index

The index of the desired child dataset. The index is zero-based, that is, the first dataset has index 0, the second - 1, and so on. Index of the last child dataset is LogDataScheme.ChildCount - 1.

Property Value

A LogTableData, TextLogData or PictureLogData object, which contains the desired log item’s data. To determine the type of the resulting object, use its Scheme.DataType property.

Remarks

If you use Python or DelphiScript, you should enclose the parameter of the ChildDataByIndex property in square brackets: ChildDataByIndex[Index].

You can also obtain the child dataset for the given row using the ChildData or ChildDataByName property.

Example

The following example demonstrates how to obtain a row’s child dataset for data displayed in the Details panel and how to export that data to an external file.

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

JavaScript

function TableDataRowSample()
{
  // Obtains a log item
  var Logs = Project.Logs;
  var LogItem = Logs.LogItem(0);
  // Obtains the log item’s dataset
  var LogData = LogItem.Data(0);

  var DType = LogData.Scheme.DataType;
  // Checks whether the dataset corresponds to the table
  if (DType == 0)
  {
    // Obtains a table row by its index
    var Row = LogData.Rows(0);

    // Obtains the dataset by its index
    var ChildDataSet = Row.ChildDataByIndex(1);
    // Checks whether the dataset is TextLogData
    if (ChildDataSet.Scheme.DataType == 1)

    {
      // Specifies an external file to export the text to
      var ExportFileName = "D:\\Work Folder\\ExportedLog\\Details.html";

      // Exports the text from the Details panel to the external file
      FS = getActiveXObject("Scripting.FileSystemObject");
      ExportFile = FS.CreateTextFile(ExportFileName, true);
      ExportFile.WriteLine(ChildDataSet.Text);
      ExportFile.Close();
