Clearing filters in a grid

I am working on clearing filters in the grid.

grid.filters.clearFilters() will clear the filters on page refresh i.e开发者_开发技巧 it will uncheck the checkbox and all the records are displayed but the text in the textbox is not cleared

How can i clear the texbox value when i hit page refresh.

Doing this when grid's render event is fired:

Ext.getCmp('my_textbox_id').reset();

You can use javascript to clear your textbox check. Just search google on how to do this.

Check and uncheck checkboxes in Javascript
