ListGrid Multiple Select - get Fields / Columns

[feuse8]

Hi,

just started using SmartGWT 2.4 and came over a question:

I created a ListGrid and added a SelectionHandler to enable selecting some items. I would like to get the selected Columns or selected Fields. (Finally an Array containing the selected fields).

As the SelectionEvent doesn't provide this information, I am wondering if there is any other approach to get the (range of the) Selected fields.

The CubeGrid component supports cell-level selection. The ListGrid does not have a notion of selecting individual fields, just records.

Thanks for your post! It seems that CubeGrid is only available in the Enterprise Edition. Is there no possibility to select cells in the free edition?

hi ,there are two methods ,

ListGridRecord[] getSelection()
The selection associated with the listGrid.
ListGridRecord[] getSelection(boolean excludePartialSelections)
The selection associated with the listGrid.

Check this

First you use the previous method and get all selected records,
then u getcellstyle of the columns ,if selected state ,do ur operation

check the method description
getCellStyle

protected String getCellStyle(ListGridRecord record,
int rowNum,
int colNum)

Return the CSS class for a cell. By default this method has the following implementation:
- return any custom style for the record (see recordCustomStyleProperty) if defined.
- create a style name based on the result of GridRenderer.getBaseStyle and the state of the record.
The state of the record is indicated by adding a suffix to the base style. There are four independent boolean states, which are combined in the order given:

1. "Disabled" : whether the cell is disabled; enable by setting the "enabled" flag on record returned by getCellRecord
2. "Selected" : whether cell is selected; enable by passing a Selection object as "selection"
3. "Over" : mouse is over this cell; enable with showRollovers
4. "Dark" : alternating color bands; enable with alternateRowStyles

For example, with a baseStyle of "myCell", a cell which is selected, which the mouse is over, and which is in a dark-colored band will get a styleName of myCellSelectedOverDark.

Cell Styles customizable by:

* attaching a custom style to a record by setting record[this.recordCustomStyleProperty] to some valid CSS style name.
* modifying the base style returned by getBaseStyle() [see that method for further documentation on this]
* overriding this function

"Selected" style can be ignored by setting showSelectedStyle to false.
Note: This is an override point

Parameters:
record - record object for this row and column
rowNum - number of the row
colNum - number of the column

Thanks for your reply but there doesn't seem to be any possibility to select single or multiple cells instead of records / rows in ListGrids.
