Working With Specific Cells in Syncfusion GridControl

Applies to TestComplete 14.30, last modified on November 21, 2019

Syncfusion's GridControl offers a variety of cell types: combo boxes, check boxes, radio buttons, spin boxes and cells with various drop-down editors. In the Obtaining and Setting Cell Values in Syncfusion GridControl topic, we defined the SetCellValue and InputCellValue routines that can be used to change grid cell values in general. However, you may need to modify the cell value in a specific way, for example, increase the value using the spin buttons, or simulate actions in the cell’s dropdown editor.

Generally, there are two approaches to modifying GridControl cell values:

  • Simulating user actions over cells, for example, clicking a cell’s check boxes and radio buttons.
  • Using internal properties and methods of the GridControl object.

The first approach is cumbersome, whereas, the second one is easier to implement. However, the first approach may be more preferable because it performs “real” actions over the grid and triggers the corresponding events of the grid control, like during normal application usage by the end users. When you modify cell values using the corresponding properties and methods of the grid control, events bound to user actions are not fired, so in this case the tested application may behave differently from what you expect.

The following sections explain how to perform typical operations over certain types of GridControl cells.

To perform these actions, TestComplete should have access to internal objects, properties and methods of the GridControl object. For this purpose, the .NET Application Support plugin must be installed and enabled.

When testing Syncfusion GridControl controls, use specific methods and properties of the corresponding SyncfusionEssGrid 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 GridControl 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.
Clicking In-place Editors' Buttons

The GridControl can contain cells with embedded buttons, for example: cells with radio buttons or spin buttons, combo box cells and cells with drop-down editors. The cell buttons are usually used to modify the cell value in a special way, invoke custom dialogs, or perform other actions, so you may need to “press” these buttons in your test scripts.

To simulate a mouse click on the buttons, use the Click action. You need to know the desired button coordinates, which you can calculate using internal properties and methods of the GridControl object. The following example demonstrates how you can determine the cell’s button coordinates and simulate a button click.

Working With CheckBox Cells

You can change the checked state of a CheckBox cell in the following ways:

  • By simulating a mouse click on the check box using the Click action.
  • By selecting the cell and “pressing” the Space key using the Keys action. For more information on selecting cells in the GridControl, see Selecting Cells in Syncfusion GridControl.
  • By assigning the cell’s CellValue property the desired value: True (checked) or False (unchecked). If the check box works in the three-state mode (that is, if the cell’s TriState property is True), you can also put the cell into an indeterminate state by assigning the CellValue property with the corresponding value (usually, empty string). For more information on modifying cell values, see Obtaining and Setting Cell Values in Syncfusion GridControl.

The script sample below implements the first approach. It demonstrates how you can calculate the check box coordinates and simulate a mouse click on it.

Working With RadioButton Cells

To change the selected radio button in a RadioButton cell, you can do any of the following:

  • Simulate a mouse click on the desired radio button. For example, you can do this using the ClickCellButton routine defined above in the Clicking In-place Editors' Buttons section.
  • Select the cell and then use Right Arrow or Left Arrow keys to select the desired radio button. To simulate arrow key presses, use the Keys action.
  • Assign the zero-based index of the desired button to the cell’s CellValue property.

We use the first approach, in the example below, to simulate a click over the needed radio button.

Working With PushButton Cells

You can “press” a PushButton cell by simulating a mouse click on it. In the Selecting Cells in Syncfusion GridControl topic, we have explained how you can simulate cell clicks. The following example uses the ClickCell routine from that topic to perform a click on a PushButton cell.

Working With Drop-Down Editors

Syncfusion GridControl offers various cells that use drop-down editors. For example, a ComboBox cell uses a drop-down list of items, a MonthCalendar cell uses a drop-down window containing a Month Calendar control.

You can display a drop-down editor in the following ways:

  • By simulating a mouse click on the cell’s down arrow button.
  • By selecting a cell and pressing the F4 key.
  • By selecting a cell and calling the CurrentCell.ShowDropDown method of the GridControl object.

You can also use the following properties and methods of the GridControl object to check whether the popup window is currently open and to close it:

  • CurrentCell.IsDropedDown: Returns True if the drop-down editor is currently opened, and False otherwise.
  • CurrentCell.CloseDropDown(Reason): Closes the drop-down editor. The Reason parameter specifies whether to save the changes made; pass the “Done” value in order to save the changes and “Cancel” to discard changes.

To get access to the drop-down window, use the dedicated property of a grid’s CurrentCellRenderer object. For example, the CurrentCellRenderer.ListBoxPart can be used to obtain the drop-down combo box or GridListControl, the CurrentCellRenderer.calendar property returns the drop-down Month Calendar control, and so on.

Note that in this way, you obtain the “native” .NET object corresponding to the editor. To obtain a window or a Win32 object corresponding to the editor control, you can use the Sys.WindowFromHandle method and pass the control’s handle (the Handle property value) as a parameter. You can then use properties, methods and actions of the obtained object to simulate user actions over the editor.

The following example illustrates how you can open drop-down editors (namely, a combo box and Month Calendar editors), access them and simulate user actions over them.

Note that most drop-down editors in GridControl support the automatic completion feature. It means that you can select an item or value from the editor by typing the item caption into the cell.
