Via the internal windows, all the controls of the container column can have a different content for each row of the Table control.

The Container columns are available for the TreeView Table controls.

Steps to follow

1. If necessary, create a Table control (based on a data file, populated programmatically or based on a variable).
2. Create a Container column (via the popup menu of the Table control or from the description window of the Table control).
3. Increase (if necessary) the height of the rows found in the Table control with the mouse.
4. Position the requested controls in the Container cell of the first row found in the Table control. You can:
   • move the existing controls in the window to the Container column.
   • drag and drop the items from the analysis displayed in the "Project explorer" pane.
5. In the description of the Container column, specify (if necessary) the main control of the column ("General" tab) and validate.

Main control of a Container column

• The sort of the Container column will be performed on the main control.
• The searches performed in a Container column will be performed on the main control.
• The additions, the modifications, ... performed through programming: the value of the column specified in TableAddLine for example will be assigned to the main control.
• The exports performed from the Table control (exports to Excel, Open Office, Word, ...) will take into account the value of the main control of the column.
• If the Container column is linked to a data file or to a variable, the control actually linked will be the main control.

Limitations

• In the Container columns, the Check Box controls must be assigned with a string in the following format: "<True/False>;<True/False>;<True/False>...".
  Similarly, the value returned by these Check Box controls is a string in the following format: "<True/False>;<True/False>;<True/False>...".
• The captions of the options found in the Radio Button and Check Box controls cannot be customized for each row in a Container column.
• To use a control with a different value for each row found in a Container column, all you have to do is include this control in an internal window and insert an Internal Window control into the column. This tip can be used for the Radio Button and Check Box controls for example, ...

Table control based on a data file or Table control based on a variable

• solution 1: keep the link between the main control and the item found in the data file. The Container column is linked to no item.
• solution 2: link the Container column to the item associated with the main control and delete the link at control level.

Table control populated programmatically

Handling the controls found in the Container column

• Assigning a value to a control:
  
  COL_Column1[RowNum].EDT_FirstName = "Flora"
  
• Assigning elements to a Combo Box control of a container:
  
  COL_Column1[RowNum].COMBO_Combo1.Content = "Element 1" + CR + "Element 2"
  
• Modifying a control property:
  
  COL_Column1[RowNum].PriceBT.Color = LightRed
  
• Indirection on a control in a Container column:
  
  sControlNameInContainerColumn is string
  sControlNameInContainerColumn = "TABLE_WithContainerCol.COL_Container[" + ...
  nRowIndex + "].EDT_InContainerCol"
  //or
  //sControlNameInContainerColumn = "TABLE_WithContainerCol[" + ...
  // nRowIndex + "].COL_Container.EDT_InContainerCol"
   
  Info({sControlNameInContainerColumn})
  
• Adding a row into a Table control found in a Container column:
  
  TableAddLine(TABLE_WITH_INTEGRATED_TABLE[RowNum].TABLE_In_Container, ...
  "Content_Col1", "Content_Col2")
  

• Change the internal window in an Internal Window control of a Container column:
  
  // Load the internal window IW_Internal Window1, on the row RowNum of an Internal Window control
  // named IWC_InternalWindowControl in a container column of a Table control
  // Caution: the IWC_InternalWindowControl control must have
  // the option "Identical content for all the rows" unchecked
  // ("UI" tab of the description window)
  ChangeSourceWindow(TABLE_NoName1[RowNum].IWC_InternalWindowControl, IW_InternalWindow1)
