Deselecting a ttk::checkbutton - checkbox

I have defined multiple ttk::checkbutton in a table. There requires a single Master checkbutton which will select or deselect all other checkbuttons at once. We can also select single checkbutton.
Now the problem is, I can select the child checkbuttons But I can not deselect them through code. I know I can deselect them all with a variable but I dont want to do that.Because all checkbuttons will then be linked. what to do.
Is Linking all checkbuttons with with different variables and then reseting them is the only option ?
Select code which works fine:
$childCheck state selected
the deselect code I have tried but failed:
$childCheck state deselected

Just got the answer. :)
Instead of deselected use !selected in state.
$childCheck state !selected

React Select: Does not show the selected values in the field after closing the dropdown

Good evening, i'm using this npm for selecting mutiple values: https://www.npmjs.com/package/react-select
A issue is occurring after choosing multiple values. The select compoment do not show the selected values if I close it and opening it again. The function works but I dont know why the values isn't showing afterwards. I would like to allow a user to see their selected choices and continue to add or remove values without losing it when they close it.
Code here: https://codesandbox.io/s/nice-stonebraker-vx73t?file=/src/App.js
Any reason why?
You cannot wrap the react-select with the MUI select, that's causing the react-select to go on and off from the DOM, and every time it is back it's empty as the state it holds gets reset.
If you check the documentation from MUI select you can tell it is intended to have MenuItem elements inside, not other things.
TL;DR, just don't wrap react-select with the MUI select and you should be fine.

Trigger event when headerCheckboxSelection is marked?

I've been reading the ag-grid documentation and I haven't been able to find out if there's any event to know when the checkbox to select or un-select all column was clicked.
I know I can use onRowSelected() but I need to know when Select or un-Select All is clicked so I can make a different operation.
I don't see an option as of right now either, what I would do though is listen for the onRowSelected then compare the selection range (using gridOptions.api.getSelectedRows) to the total rows (using gridOptions.api.getModel) and do something if they are the same
Alternatively you could try adding a listener to the select all element it can be found with the class .ag-header-select-all though I am not quite sure how I would do that.

Select Unselect logic in Salesforce

I have a requirement, where there is a checkbox on UI when I select it the first time it gets selected when I click it again it is deselected.
So in logic, I am adding the selected parameter to a set, and if it is already present I remove it for deselecting the parameter.
But this approach is not working when I have to count how many I have total, it gives incorrect values.
I have to implement select multiple and deselect multiple in a web page. Can anyone help me with this
Do you have a wrapper? Have a select all/deselect all command link, that command link will call an action which will select/deselect all of the records, then just rerender the table..

CQ5 checkboxes false

I would like to have it where i can only select one checkbox at a time and when selected show the textfield associated with the selection. At least have it where i can only select one checkbox at a time. I have setup the dialog to run a choose when statement when for the selections but only want to select one at a time.
You can use listeners to react to user actions e.g.: dynamic dialogs, however you probably want to use radios.
