I was using a new Ext.grid.CheckColumn in my EXTJS FlexGridPanel
Now the column of checkboxes do not allow multiple selections , so I need to replace it with a column of radio buttons.
Is it possible to make the CheckColumn as single-select?
If not, how can I put the column of radio buttons. In this link, it seems like the grid does not support radio buttons.

I say this because there is CheckboxSelectionModel but no RadioButtonSelectionModel
CheckboxSelectionModel has a property singleSelect. Is that what you need?

I would like to add a Select/Deselect All Columns checkbox under Columns before the column names in a grid panel to show/hide all columns. As there are large number of columns in grid so user wants to select all then uncheck which they want to hide or deselect all and then check which they want to show. I am using ExtJS 3.4 version.
For example, select/deselect all checkbox should come before First Name among the list under Columns tree in below sample grid:

Thanks!
I don't think there is an out of the box solution to this. you could add a checkbox a the top and set all the menu check boxes to have a bind that will check all the boxes
bind: {
checked: '{rullForThisCheckbox || checkAllCeckboxes}'
}
then you would set the checked in the top checkbox to just {checkAllCeckboxes}
You could access the columns menu and manually insert the select/deselect all checkbox.
I have tested and it works, though it doesn't look pretty out of the box.
grid.getHeaderContainer().getMenu().add({
xtype: 'checkboxfield',
fieldLabel: '(de)select all',
})
I am using checkboxmodel grid in extjs for display values.

Use checkOnly: true on the selection model:
True if rows can only be selected by clicking on the checkbox column,
not by clicking on the row itself. Note that this only refers to
selection via the UI, programmatic selection will still occur
regardless.

I want to create a ComboBox having Checkboxes as children using Codename one.
I am not using the UIBuilder
For reusability I created a Container having three Checkboxes in it:
OverviewCheckBoxContainer
- Checkbox1
- Checkbox2
- Checkbox3
and this works already.
As it takes too much space on the screen, I now tried to add the CheckBoxContainer into a Combobox, like this:
ComboBox
- OverviewCheckBoxCont
-...
but it does not work, the ComboBox contains a single entry only and it's not a checkbox, but a text:
OverviewCheckBoxCont[x=...
(cannot see further on the screen)
How can I solve this issue, so there is a dropdown menu containing the three Checkboxes, that toggle onClick?
ps:
In the main form I added the CheckBoxesComboBox instead of the CheckBoxesCont:
this.add(BorderLayout.CENTER, checkBoxesComboBox)
instead of
this.add(BorderLayout.CENTER, checkBoxesCont)
1.You can use simple combobox as shown below
ArrayList al = new ArrayList();
findComboBox().setModel(new DefaultListModel(al));
2.And to add checkbox in combobox , you have to customize the combobox
3.Instead of customizing combobox, You can use button which shows and hides OverviewCheckBoxContainer which contains list of checkboxs
See this for customizing the ComboBox with the generic list cell renderer: https://www.codenameone.com/manual/components.html#_combobox
The problem with using checkboxes in a combo is that you would assume they would all appear in the combo as a set and the combo wasn't designed to do that. I would instead just use a Button and show a dialog with a set of checkboxes then set the text of the Button to match the result. You can style the button to look like a ComboBox if that is your preference.
How to add a Textbox Column in a GridPanel. Editor feature of Gridpanel displays textbox only on doubleclick on the cell. But I want the textboxes in the column to be displayed by default.
Thanks in advance
I don't believe there's a config option or component for this. You can try to work around it by adding the textfield in the "renderer"
You can define property like editor: textField in the column model of the grid that will display textbox in the column model.
I am using checkboxselectionmodel in ExtJS grid?
when i clicked on the row the row get selected and the respective checkbox also checked ..
But i need the checkbox to be checked only when i click the checkbox otherwise i want row
only get selected ...
Please help me out...
Thanks & Regards,

In your CheckboxSelectionModel set checkOnly config option to true.
The CheckboxSelectionModel links row selection and checkbox selection. You want row selection to be independent from the checkbox - so use RowSelectionModel and add a Checkbox into the first column of your grid.
