使用行编辑器进行编辑时，如何在extjs 4.1.1中禁用行的特定单元格？

Question

How can I disable a particular cell of a row when edit in extjs 4.1.1? i am using gridrow editor. I have a grid which has 2 columns, name and age. When click for edit I have to disable the name field, the user can only edit age.

Answer 1

If you can only edit using the row editor, then don't specify the editor config on the column. If you can add too, then you could try the following ( I haven't ever done it myself, but it should work) :

grid.on('beforeedit', function(editor, e, eOpts) {
     // if editing.. 
     this.down('column[dataIndex=name]').setEditor(null);
     // else
     this.down('column[dataIndex=name]').setEditor(/* editor config */);
}, grid);

Answer 2

You can use this

grid.on('beforeedit', function(editor, e, eOpts) {
         // if editing.. 
         if(e.field == "name"){
               e.cancel = true;  
          }
    });

Setting e.cancel as true will disable the field from editing.
