Grid Panel
In case of grid or filter+grid or grid+detail form , the grid definition panel is showed; through it the user has to define settings related to the grid component:
grid title (optional, can be hidden)
business component (for list of data) to link to the grid; the fields specified in the select clause are used to automatically
create the grid columns; user can then show/hide each of them, as well as define many other column settings
grid width and height
flags to show/hide border and to set panel opacity
flags to allow the CRUD operations, i.e. insert, update and delete (only if the data model linked to the selected business component is writable); in case of insert enabled, it is possible to specify the maximum number of rows to insert before saving them
data fetching policy: read all or a block of data and its size
flag to define if data loading is automatically performed when the grid is showed
initial grid mode, when the grid is showed; grids and forms have 3 alternative modes: readonly, insert, edit; in insert mode a new row is showed; through up/down arrows is possible to add/remove (empty) rows; in edit mode, all rows are editable or the one only (selected row), according to the flag "multiple changes"
flag "copy enabled", used to show a "copy" button in the grid toolbar, used to switch to insert mode the grid, add a new row an copy the values from the selected row to the new one
number of columns anchored to the left of the grid (0 by default)
boolean javascript expression "disable when", to disable everything when the boolean condition is true flags "enable columns permission" and "enable columns profile", used to manage these special features, described in a separate section
find empty - flag used to include two additional buttons to the quick filter panel: a "Find empty" and "Find not empty" values. These buttons have their own CSS class: "filterempty" and "filternotempty". Use it only with a relational database. When flagging this check-box, you have also to change the x-theme.css content and define how to render these two buttons, according to your theme. If your them does not show icons but it shows text, you could change the grid filter section of your theme in this way:
When creating the grid, a grid toolbar is automatically showed on top of it; this toolbar always includes the reload button; the other buttons (insert, edit, delete and save/cancel) are showed/hidden according to the flags described above. These buttons change the current grid mode, according to the following policy:
insert button, from readonly mode -> insert mode, insert/edit/delete buttons are disabled, save/cancel buttons are enabled
edit button, from readonly mode -> edit mode, insert/edit/delete buttons are disabled, save/cancel buttons are enabled
delete button, from readonly mode -> after confirming the operation, the selected records are deleted
cancel button, from insert/edit mode -> after confirming the operation, the grid is switched to readonly mode and the content reloaded
save button, from insert/edit mode -> the grid is switched to readonly mode if the saving operation has been performed successfully.
Column types
Through the "type" property for a column, it is possible to set a wide range of different columns; they differ for the way they are rendered, according to the current cell mode: rendering or editing (i.e. when the user clicks on it and an editor is showed).
Supported types are:
Button - a clickable button is rendered in both modes; a click event can be linked to it, through Column Events folders
CMS File - it shows a clickable button to use when the grid is used combined with the "Internal CMS module"; the button leads to a File Upload Dialog, to manage File upload/download/Preview and its automatic reading/writing into the CMS module; when this type is set, the Directory property must be set as well
Checkbox - a checkbox is rendered in both modes and the checkbox is clickable in insert/edit grid modes; when this type is set, also Positive/Negative value properties must be set
Counter based on a component - this type cannot be changed, since it is inherited by the bounded data model
Counter based on a table - this type cannot be changed, since it is inherited by the bounded data model
Date - it shows a date formatted according to the current user language; in insert/edit grid mode, the cell is editable and a calendar can be opened to choose the date
Date+Time - it shows a date+time formatted according to the current user language; in insert/edit grid mode, the cell is editable and a calendar can be opened to choose the date
File Id - it shows a clickable button to use when the grid is used combined with the "Alfresco ECM module"; the button leads to a File Upload Dialog, to manage File upload/download/Preview and its automatic reading/writing into the Alfresco module; when this type is set, the Directory property must be set as well
File Path - it shows a file name or a button (in insert/edit grid mode) to choose a file; when filling this type, the Directory property must be set too
Image URL - it shows an image as a preview; the cell contains behind the scenes the image file name; cell editing is not allowed; when filling this type, the Directory property must be set too
Internal counter - this type cannot be changed, since it is inherited by the bounded data model
Number - numeric input field, with a large variety of different properties; support for integer/decimal/currency values
Path images - ?
Sequence/Autoincrement - this type cannot be changed, since it is inherited by the bounded data model
Text - text input field
Text area - multi-line text field (not a very good choice for a grid...)
Time only - it shows a date formatted according to the current user language; in insert/edit grid mode, the cell is editable and a calendar can be opened to choose the date
Tree Lookup - no value is showed when rendering the cell; when editing the cell, a "lookup button" is rendered: when clicking on the button a "lookup tree" is showed, in order to select a node from the list (the code to set in the cell); when filling this type, the Selector property must be set too
UUID - this type cannot be changed, since it is inherited by the bounded data model
Upload to directory - an old version type; it is recommended not to use it any more
Summary row
Optionally, a summary locked row can be showed on the bottom of the grid; this read only row is automatically showed only if there is an "update summary row" event linked to the grid: in that case it will be showed and the javascript action binded to the event is invoked for each column, every time a cell is changed. In order to avoid setting a total value for a specific cell, a ‘’ can be returned to that callback in the action. It is possible to set foreground and background colors for a cell through css class names (see details specified below for the "update summary row" event).
Example:
or
Grouped columns in multiple groups
Optionally , it is possible to group columns in multiple groups, so that there will be a hierarchy of headers, spread in multiple header rows.
In order to do it, add the "Column header" panel event to the grid and define a client-side javascript action containing the headers definition.
Important note: pay attention to the hidden columns. With grouped columns you have not to make "selectable" any other non visibile column and it would be better to make them "not managed as well". As an alternative, you have to move all visible columns at the beginning and move all not selectable, not visibile but managed columns all on the right.
An example of such a definition is the following:
Locked columns
Optionally, a group of locked columns can be anchored to the left side of the grid. In order to do it, set the "Locked columns nr" in the grid definition window.
In case locked columns are combined with grouping columns, a new grid is rendered, composed of a tree+grid, where grouping columns become tree nodes, which are anchored on the left side of the grid. That means it is not supported a grid having grouped columns+locked columns.
Additional configuration
Optionally, it is possible to include in the grid definition, additional settings, through the Additional Config multiline field in the grid definition window.
Supported settings are the one reported in the official ExtJS 3.3 documentation:
Moreover, a few other settings are supported:
overrideBeforeEdit: true, overrides the default behavior of cell editing in a grid, based on the grid mode and allows to fully customize the grid behavior, independently of the current grid mode. Pay attention to this property, since it can easily lead to data inconsistencies with regards to the saving operations and toolbar state. Use the "before cell editing" event of a grid to customize grid behavior: in the bounded action, return true to allows cell editing, return false to make the cell not editable
insertUpdateHidden (since 6.0.2): 'Y' if you want hide the insert or update control in import form ('N' default)
insertUpdateLabelKey (since 6.0.2): set the key of translation for the label of insert or update control in import form
insertUpdateDisable (since 6.0.2): 'Y' if you want disable the insert or update control in import form ('N' default)
insertUpdateDefaultValue (since 6.0.2): 'Y' if you want checked the insert or update control in import form ('N' default)
Bear in mind that all settings specified in the "Additiona config" input box must end with a comma.
