Select and Unselect record on ListGrid

[olinsha]

Hi,

I would like to set a specific selectionType for my ListGrid :

In fact I want to have the following mode :

* single selection (as in the SINGLE mode)
* AND possibility to unselect the selected row by clicking it (toggle mode like in SIMPLE mode)

How may I do that ? I think that this hybrid mode should be added in the SelectionType for ListGrid.

Thank you for your help

If you're running against SVN, you can add

grid.setSelectionAppearance(SelectionAppearance.CHECKBOX);

This will place a checkbox in the first column for selection where you can toggle selection.

Hi Sanjiv,

in fact I have a form linked to my grid so your solution is not good for me because I want to avoid multiselection to avoid messing the users with the form display.

Just adding the unselect possibility to the SINGLE mode would be great !!

You could simply add a click listener that deselects the row it is already selected.

Hi Sanjiv,

this is exactly the idea I had. But how can I deselect the selected row ? There is no such method on grid or on rowclickevent as far as I know.

Have you tried ListGrid.deslectRecord along with ListGrid.addRecordClickHandler(..)?

oops
thank you sanjiv
I was exploring all the grid methods and I don't know how I missed the deselect methods that fit my need.

Thank you !!

There is:
setSelectionType (SelectionStyle.SINGLE);
but it doesn't seems to do anything in my code
(I am using smartgwt-1.0b2.zip, I got it at 10/Jan/2009)
Is it a bug and it will be fixed?

SINGLE mode only allows you to select one record at a time
You can't deselect it on clicking on it once again. To do so please use the method deselectRecord as given by sanjiv ;)

No, I mean that even if I set SelectionStyle.SINGLE, the mode remains MULTIPLE.
The SINGLE mode is not working in my case (not in ListGrid or even in TreeGrid)

[smartgwt.dev]

This sample users SelectionStyle.SINGLE and works fine in the SVN build.

[olinsha]

hum,

I have to admit that the SINGLE mode seems to not work well : I have same issue on grids : I set them to SINGLE mode by adding

setSelectionType(SelectionStyle.SINGLE);

to my grid but I still can multiple select data in this grid.

I don't know how the example in the showcase is working, it seems to just call the same method than above.

Any idea ?

Can anyone post a standalone test case that actually demonstrates the issue?

setSelectionAppearance

setSelectionAppearance(SelectionAppearance.CHECKBOX)

congratulations on that!
works great and is exactly what I needed!

The following code creates a working LlistGrid but it fails to set the SelectionStyle.SINGLE


public class ListGridCriteria extends ListGrid
{
private ListGridField m_fieldCriterio, m_fieldValue;

public ListGridCriteria ()
{
setWidth100 ();
setHeight100 ();

setSelectionType (SelectionStyle.SINGLE);

m_fieldCriterio = new ListGridField("criterio", "Κριτήριο", 60);

m_fieldValue = new ListGridField("value", "Τιμή");
m_fieldValue.setWidth ("*");

setFields (m_fieldCriterio, m_fieldValue);

loadListGrid ();
}
private void loadListGrid ()
{
ListGridRecord[] rr = new ListGridRecord[5];
for (int i=0; i<5; i++)
{
ListGridRecord r = new ListGridRecord ();
r.setAttribute ("criterio", "criterio");
r.setAttribute ("value", "value");
rr[i] = r;
}

setData (rr);
}
}
