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 am using Material ui datagrid. I want to get the value on uncheck of checkbox also.
I have an API which update the Datagrid, on selection I get the selected row data which then on button click I update the value into another array of object, Now when I close the datagrid and open again I want the data to be shown in table comparing if already present in array of object mark it as selected in checkbox, Now when i deselect the checkbox i need the ID and the row data which was removed so I can update the array again, but here on deselect the checkbox it shows empty, so how I can get the removed one so I can update my array

I have a Ext grid with checkbox selection Model. The grid contains multiple pages of 50 records each. I have a 'Clear Selections' button to deselect all the selected rows in the selection model.
The code for this is :
handler: function(){
this.selectionModel.deselectAll();
this.selectedReordsArray.clear();
},
scope: this
The problem is, when I select some records in the first page and move to second page and select some records there as well. Now if I click 'Clear Selections' button it deselects the rows on that page i.e. second page , but when I go back to page 1 , the rows there are still selected.
Is there any way to remove checkbox selections from all the pages.
Thanks,
PS : I am using Ext JS 4.1.3
Add "pruneRemoved: false" for your selmodel. Then try adding deselectAll() method for your gridstore. This will clear selected records from all pages.
I have a grid with one column, which when the user selects, is used to display information in various textfields, checkboxes which are embedded in a panel on the right. I have implemented a delete feature at the row level in the grid. Now I wish either of these two things to happen.
1) Either the default selection is such that the first row is by default selected after deletion of any row.
OR
2)The information in the various components in the panel on the right is cleared.
Currently what happens is that the information which corresponds to the deleted row stays after deletion since nothing is selected in the grid so the previous selected option is used to display information on the right.
As removing the record from the grid implies deselecting it, you really just need to listen for changes to the selection in your grid and implement the desired behaviour when no selection exists.
I'd recommend the selectionchange event, as you can cover both selection and deselection by inspecting the new selection state:
grid.on({
'selectionchange': function(sm, selectedRecords) {
if (selectedRecords.length === 0) {
// no selection -> clear fields or select the first row
} else {
// selection exists -> load data into fields
}
}
});
(assuming you're using single selection, i.e. either one or no row can be selected)
In extjs I have a GridPanel. The GridPanel has some hidden columns. Now when I click on the Grid menu, there is an option called 'Columns'. When you mouseover 'Columns' you can check/uncheck the columns you want to show/hide.
Be default the hidden columns are also showing up on mouseover. Is there a way to avoid this?
You can use such a property for your columns:
hideable:false
In this case these columns can not participate in showing/hiding.
from column def reference:
hidden : Boolean
Optional. true to initially hide this column. Defaults to false. A hidden column may be shown via the header row menu.
If a column is never to be shown, simply do not include this column in the Column Model at all.

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.
