Grids

Grids are the main component in AWE to show data lists. It is defined by grid and columns:

• The grid is the container of the data list. It has the query to load and a set of attributes to define the behaviour of the grid.
• Each column contains the source of the data from the data list, the label of the column and other attributes to manage each column cell.

There is also a group-header tag which is used to show a second level header over a group of column headers.

XML skeleton

To define a grid or a treegrid in AWE you must follow the next structure:

<grid id="[grid-identifier]" ...>
  <column ... ></column>
  ...
  <group-header ...>
    <column ...></column>
    ...
  </group-header>
  ...
  <button ... > ... </button>
  ...
  <context-button ...> ... </context button>
  ...
</grid>

<grid id="[grid-id]" style="[grid-style]" 
      multiselect="[grid-is-multiselect]" checkbox-multiselect="[checkbox-multiselectable]" editable="[grid-is-editable]" send-operations="[grid-is-multioperation]" initial-load="[initial-load]" server-action="[server-action]" target-action="[target-action]" max="[elements-per-page] pagination-disabled="[pagination-disabled]"">

</grid>

Specific row style

When you need set specific style to all cells of one row (ex.: change background color), you can add a new field called _style_ with CSS style name.

<query id="MyQuery" >
    <field id="_style_" alias="_style_" variable="styleClass"/>
    <variable id="styleClass" type="STRING" value="red"/>
</query>

Specific column components

There are several components developed specifically to be used in grid cells. These components need a special structure on the query which fills them:

<compound alias="specialCell">
  <computed alias="value" format="xxx"/>  
  <computed alias="label" format="xxx" translate="EnumTranslate"/>
</compound>

These are the cells which use the special structure:

Standard cell without components

When you send a compound structure to a standard cell, you can use the following attributes:

Attribute	Description
value	Value which will be sent to the server
label	Text which will be shown. You can use i18n files (locales)
title	Text to show when you move the mouse over the icon. You can use i18n files (locales)
cell-style	CSS class to format the contents

Text view column component

This component is very useful to show an styled text inside a grid with an icon. The compound attributes to fill this component are the following:

The tree grid is a grid that can be expanded as a tree. It can be defined as standard tree, loading tree, editable tree or multi-option tree, and combinations between them.

The data structure needs an identifier per row, and also a parent identifier, with no value if the row is a root row (with no parent). The identifier field must be defined on the grid tree-id attribute, and the parent must be defined on the tree-parent attribute.

    </dependency>
  </column>
  ...
  <button label="BUTTON_NEW" icon="plus-circle" id="ButGrdKeyLstAdd">
    <button-action type="add-row" target="GrdKeyLst" silent="true" />
  </button>
  <button label="BUTTON_DELETE" icon="trash" id="ButGrdKeyLstDel">
    <button-action type="delete-row" target="GrdKeyLst" silent="true" />

    </dependency>
  </button>
</grid>

Context menu

You can define a context-menu inside the grid to help the user do actions with the selected rows. See context menu.

Variables

The grid component sends some specific variables to the server, depending on its status and attributes. Here is the list of variables that can be sent by the grid component:

Variable	Type	Condition	Description
[GridName]	Array	Always	List of selected lines identifiers
[ColumnName]	Array	send-all="false"	List of selected lines column values (for each column)
[ColumnName]	Array	send-all="true"	List of all column values (for each column)
[ColumnName].selected	Value/Array	Always	List of selected lines column values (for each column). If there is only one row selected, it will send only the value instead of an array
selectedRowAddress	JsonNode	When there is only one line selected	Json node with the address of the selected row: view, component and row id
sort	Array	Always	List of JsonNodes with the grid sort information (id: column id, direction: sort direction)
[GridName].data	JsonNode	Always	List of grid extra information (page, max records, sort information, etc)

The multioperation grid sends the variables in a different way than the other grids:

Variable	Type	Condition	Description
[GridName]	Integer	multioperation="true"	Number of sent operations
[GridName].RowTyp	Array	multioperation="true"	List of operations required for each column (only for the rows with operations)
[GridName]-id	Array	multioperation="true"	List of row identifiers for rows with operations
[ColumnName]	Array	multioperation="true"	List of column values for rows with operations (for each column)
[ColumnName].selected	Value/Array	Always	List of selected lines column values (for each column). If there is only one row selected, it will send only the value instead of an array
selectedRowAddress	JsonNode	When there is only one line selected	Json node with the address of the selected row: view, component and row id
sort	Array	Always	List of JsonNodes with the grid sort information (id: column id, direction: sort direction)
[GridName].data	JsonNode	Always	List of grid extra information (page, max records, sort information, etc)
