Checkall in TreeGrid

« on: February 27, 2024, 05:40:56 AM »

Hello. I need a checkbox column in a treegrid where will only be displayed if the value of another column is different of blank. I used the formatter function and it worked. However, when making this change the checkboxall disappeared from the header. What do I need to do to make it appear?

My code:

$('#treegrid_faturar_bof_agente_medicao').treegrid({
columns: [
[{
field: 'checked',
formatter: function(value, row, index) {
if (row.chave_faturamento != "") {
return '<input type="checkbox" class="easyui-checkbox" />';
}
}
},{
field: 'nom_item',
title: 'Agente X Mês',
width: 730
}
]
],
singleSelect: true,
checkOnSelect: false,
selectOnCheck: false
});

The 'checkbox' selection is the built-in functionality in the treegrid component. Please look at this example:

https://www.jeasyui.com/demo/main/index.php?plugin=TreeGrid&theme=material-teal&dir=ltr&pitem=Custom%20CheckBox&sort=asc

If you want to custom the checkbox column, please define the 'title' property for your checkbox column.

Code:

{
	field: 'checked',
	title: '<input type="checkbox">',
	formatter: ...
}

Thanks for your help. The built-in functionality set the checkbox next to the text. I need the checkbox in a unique column. I tested the title option but when clicking on the checkbox nothing happens (not even the check is carried out). I need the checkall/uncheckall functionality. Its possible?

Thanks a lot for the help. We have one last problem. When hiding the datagrid-cell-check, the formatting of the columns is lost (see attached image). Can you help?
