Solution to Make the Checkbox in Extjs Gridpanel Unselectable Based on Certain Row Conditions

The specific code is shown as follows:

Ext.define('AM.view.test.ReceiptList', { 
  extend: 'Ext.grid.Panel', 
  alias: 'widget.receiptlist', 
  id : 'receiptlist', 
  selModel : { 
    selType : 'checkboxmodel', 
    mode : 'SIMPLE', 
    checkOnly : true, 
    renderer : function(v,p,record) { 
      if (record.data.XR0003 == '0') { 
        return '<div class="x-grid--checker"> </div>'; 
      }else{ 
        return ''; 
      } 
    } 
  }, 
  listeners: { 
    beforeselect: function(grid, record, index, eOpts) { 
      if (record.get('XR0003')!=0) { 
        return false; 
      } 
    } 
  } 
}); 

Code description:

1The red marked location is the key code;

2The code at the .renderer location represents that the checkbox is displayed only when the conditions are met during rendering.

3The code at the .listeners location represents the condition judgment before selection; if it is not equal to 0, it will not be selected.

4You can combine the two methods according to your own needs.
