I implemented Form interacting with an embedded Grid, but in this case, I can't use the cellclick event on a column of the grid.
So, How can I add a listener which fired the event cellclick.

Thanks for your help

You need to explain your case a little bit more, because all I would say is to use the cellclick event, and I would provide the listener code or point you to the direction of code that you would use, but I don't think you need that.

OK, I take an extjs sample with a form interacting with an embedded Grid.

For example if a click on the cell of one column I would like to open a popup

What's wrong with the cellclick event?

I still don't understand why you wouldn't use the cellclick event for that!

In this case we use the xtype: 'grid', to get a grid embedded in a form, but all the event which are fired with Ext.grid.GridPanel, are not fired with the grid embedded in a form ( xtype: 'grid')
(http://www.sencha.com/deploy/dev/docs/source/GridPanel.html#cls-Ext.grid.GridPanel)

In this sample, I use the cellclick to delete a row but It works if I use Ext.grid.EditorGridPanel or Ext.grid.GridPanel not for Ext.FormPanel with xtype: 'grid' (Dynamic Form interacting with an embedded Grid)



var userExceptionForm = new Ext.grid.EditorGridPanel({
id: 'userExceptionForm',
el: 'userExceptionGridForm-el',
title: '<fmt:message key="sybiladmin.userExceptions.title"/>',
cm: colModel,
store: userExceptionStore,
bodyStyle:'padding:5px 5px 0',
totalProperty: 'rows',
height: 350,
width: 818,
plugins: checkColumn,

sm: new Ext.grid.RowSelectionModel({
singleSelect: true,
listeners: {
rowselect: function(sm, row, rec) {
userExceptionSelectedRow = rec.copy();
Ext.getCmp("userExceptionDetailsForm").getForm().loadRecord(rec);
}
}
}),
listeners: {
cellclick:function(grid, rowIndex, columnIndex, e) {
if(columnIndex==grid.getColumnModel().getIndexById('deleter')) {

Ext.Msg.confirm('<fmt:message key="sybiladmin.userException.alt.delete"/>', '<fmt:message key="sybiladmin.userException.delete.confirmation"/>',
function(btn)
{

if (btn == 'yes'){
Ext.Ajax.request({
url: '<c:url value="/comref/deleteJsonUserExceptions.do"/>',
method: 'POST',
params : {
userExceptionId : userExceptionSelectedRow.get('id')
},
headers: {'If-Modified-Since' : 'Thu, 1 Jan 1970 00:00:00 GMT'},
success: function ( result, request ) {
//Ext.MessageBox.alert('Success', 'Data return from the server: '+ result.responseText);
//userExceptionStore.load();
Ext.getCmp("userExceptionDetailsForm").getForm().reset();

},
failure: function ( result, request) {
Ext.MessageBox.alert('Failed', result.responseText);

}
});
var record = grid.getStore().getAt(rowIndex);
grid.getStore().remove(record);
grid.getView().refresh();

}

} )

}
},

viewready: function(g) {
g.getSelectionModel().selectRow(0);
} // Allow rows to be rendered.
}

});

"Ext.FormPanel with xtype: 'grid'"?

What's that all about?

It certainly does work when embedded in a form. I just tried the following in the form-grid.js example:



// Grid's listeners

listeners: {
viewready: function(g) {
g.getSelectionModel().selectRow(0);
}, // Allow rows to be rendered.

cellclick: function(grid, rowIndex, columnIndex, e) {
console.log('cellclick');
}
}
