ExtJS hiding a column

How to dynamically modify the display and hiding of columns:The following is the sample code:

if (Matchstatus.getvalue () = = "Weipp") {Colmode= this. Getcolumnmodel (); var handcolindx=colmode.findcolumnindex ("Match"); Colmode.sethidden (Handcolindx,false );} Else {var colmode=this. Getcolumnmodel (); var handcolindx=colmode.findcolumnindex ("Match"); Colmode.sethidden (Handcolindx,True );}

Note that the following are:When the column is configured with theGridshow : false, you can't find the Column object. can be written in the refreshCall:

2. listeners :{
4. afterrender :function(){
6. var thisGrid =this;
8. var colMode = thisGrid.getColumnModel();
10. var handColIndex = colMode.findColumnIndex(‘satisfactionName‘);
12. if(thisGrid.petitionTypeCode==3){
14. colMode.setHidden(handColIndex,false);
16. }else{
18. colMode.setHidden(handColIndex,true);
20. }
22. }
24. },
