For columns count:
nbCols = grid.columns.length;
For rows count :
nbRows = grid.getStore().getTotalCount();
Question
I am trying make a validation with number of column condition.
Here the code I tried and return (Object [object Object] has no method 'getColumnCount')
var grid = Ext.getCmp('frm_request_form_gridpanel');
//var recordCount = GridPanel().getStore().getCount();
var count = grid.getStore().getColumnCount(true);
//output
success: function() {
Ext.MessageBox.show({
title: 'Informasi',
msg: 'Transaksi berhasil.' + count,
buttons: Ext.MessageBox.OK,
fn: function() {
myRequest.close();
},
animateTarget: 'p_content',
icon: Ext.MessageBox.INFO
});
}
Please give me solution.

For columns count:
nbCols = grid.columns.length;
For rows count :
nbRows = grid.getStore().getTotalCount();
OTHER TIPS
To get count of hidden as well as visible columns use:
var columnCount = grid.getColumnModel().getColumnCount(false);
To get count of only visible columns use:
var columnCount = grid.getColumnModel().getColumnCount(true);
Add this code to gridpanel config:
listeners: {
afterrender: function (this) {
App.gridColumnsCount = this.initialConfig.columns.items.length;
//alert(this.initialConfig.columns.items.length);
}
}
you can use
var count = grid.getStore().getTotalCount();
It retreives the total number of records in the store that is accessed by the grid.
