title: How to disable combo box in ext js
body: <p>I have grid that have Country and State column. This grid data add using combo box. After add data i want to fully disable combo box in the grid </p>
  
  <p><strong>This my code for disable combo box</strong></p>
  
  <pre><code>gridRegionsRoweditor.on('beforeedit', function(roweditor, rowIndex){
              var  record = this.gridRegions.store.getAt(rowIndex);
  
              if(typeof record.data.ROWDATE != 'undefined'){
                 grdcmbCountry.setDisabled(true);
                 grdcmbState.setDisabled(true);
                 return false;
              }else{
                 grdcmbCountry.setDisabled(false);
                 grdcmbState.setDisabled(false);
              }
        },this);
  </code></pre>
  
  <p>Above solution not perfect to me. when i double click on the one of the combo box that  view unclear combo box. How can avoided this unclear combo box form the grid?(when i disable combo box that want to look like label). Is that possible to remove double click event in the these cell for my problem?</p>
