[quas1986]

Guys,

I'm using Extjs 4.2 in my application. I have requirement like that, I have to set a comobox to the toolbar of the grid. In that combo box there will be number of rows to be shown in the drop-down menu. Now by default my grid is showing 10 row. Now what if have to do is select the row form combobox on the top like 20,30 or 50....no according to the selection , the data will generate. Any suggestion how should I do that comobox.?

Any help will be appreciable

Thanks
