how to find column index using dataIndex Extjs 4

Well in ExtJS 3 i used the following code:

grid.getColumnModel().findColumnIndex("Tasks")

I tried finding it on the api docs, but no luck...so how is ir possible that i can find the column index of the grid by the dataIndex of the column or the header name of that column.

Solution

  • You can use the component query:

    var fname = grid.down('[dataIndex=firstname]');

    It took a while to work that out - there doesnt seem to be an example in the docs. ;-)
