error in deleting row in gridpanel

[sathishs]

Hi,
To delete a row in grid panel,I used grid.getSelections(),function.but firebug shows the error
->grid has no properties
->[Break on this error] var m = grid.getSelections();

my code:js


Ext.onReady(function() {

var myData = [
['name1','author1'],
['name1','author2'],
['name1','author3'],
];

var store1 = new Ext.data.SimpleStore({
fields: [
{name: 'author'},
{name: 'title'},

]
});
function doDel(store,grid){
var m = grid.getSelections();
alert(m);
if(m.length > 0)
{
Ext.MessageBox.confirm('Message', 'Do you really want to delete it?' , doDel2);
}
else
{
Ext.MessageBox.alert('Message', 'Please select at least one item to delete');
}

}

function doDel2(btn)
{
if(btn == 'yes')
{
var m = grid.getSelections();
var jsonData = "[";
for(var i = 0, len = m.length; i < len; i++){
var ss = "{\"id\":\"" + m[i].get("id") + "\"}";
//alert(ss);
if(i==0)
jsonData = jsonData + ss ;
else
jsonData = jsonData + "," + ss;
store.remove(m[i]);
}
jsonData = jsonData + "]";
store.load({params:{start:0, limit:myPageSize, delData:jsonData}});
}
}



store1.loadData(myData);

var cm1 = new Ext.grid.ColumnModel([
{header: "Author", width: 120, dataIndex: 'author'},
{header: "Title", width: 180, dataIndex: 'title'},

]);
cm1.defaultSortable = true;

var grid1 = new Ext.grid.EditorGridPanel({
store: store1,
cm: cm1,
id : 'test',
viewConfig: {
forceFit:true
},
buttons: [
{
text:'New',
id:'new-vlan',


},{

text:'Delete',
id:'delete-vlan',
handler:doDel(),

}],



renderTo: 'example-grid',
width:700,
height:300,
collapsible: true,
style: 'padding:20px 0px 10px 200px',
title:'test',
autoScroll: true,
monitorResize: true,
frame:true
});


});
I am unable to debug this error.If any one find wats the problem pls reply.
Thx in advance

Your doDel function expects parameters store and grid, but you are calling the function without parameters.

Use:

handler:function() {
  doDel(grid1, store1);
}

Hi,
Thx for reply.After doing the above changes in my code,Now it shows grid.getSelections() is not a function.I checked API but I am not able to find this function.Is there any other functions to replace this one or shall I use the same function in different way?

What you need there is:

grid.getSelectionModel ().getSelctions ()

[sathishs]

It shows the err,
this.selModel.getSelections is not a function
[Break on this error] return this.selModel.getSelections();

[catacaustic]

It shows the err,
this.selModel.getSelections is not a function
[Break on this error] return this.selModel.getSelections();

Where are you getting selModel from? If it is actually a selection model object then it has that function. By the looks of it you're not getting the selection model right, so it can't do anything.
