Re: Add grid column on runtime

As I faced this issue, I've reallized that if I declare that column in datasource with <showIf>false<showIf>. The column will not display any where. and Do the code

tabPane.gridName.listGrid.showField('columnName to Show');

This will display the column on runtime.

Thanks for the reply,but this will solve only partial problem as suppose we add 2 coulmns and put it in hiding status,but supoose i need to add 5 coulmns or more than that at run time then this solution will not work.

Same problem here. Is there a solution somewhere?

Update: I found a solution. For further reference:

I added this function to my ListGrid class. It adds an empty column with increasing number as name

addColumn: function() {
var fields = this.getFields();
fields[fields.length] = {name:""+(fields.length+1), title:"", width:70};
this.setFields(fields);
}

var fields = listGrid.getAllFields() || [];
fields.add({ name: "field1", title: "New field" });
listGrid.setFields(fields);
