I have a Ext GridPanel named sampleGrid, which has some column. one of them is named IsAssigned holding a bool value.
I have a ext button. When I click it I want to pass all the row that has IsAssigned column value false.

Russian <ext:Button ID="btnSave" runat="server" Text="Save"
Icon="Accept">
<DirectEvents>
<Click OnEvent="btnSave_Click">
<ExtraParams>
<ext:Parameter Name="rows" Value="Ext.encode(#{sampleGrid}.getRowsValues())"
Mode="Raw" ></ext:Parameter>
</ExtraParams>
</Click>
</DirectEvents>
</ext:Button>
Here Ext.encode(#{sampleGrid}.getRowsValues()) will pass all the rows. But I want to pass only rows that have IsAssigned column value false.
isAssigned column code:
<ext:CheckColumn ColumnID="chkSelect" DataIndex="IsAssigned" MenuDisabled="true"
Sortable="true" Width="30px" Editable="true">
</ext:CheckColumn>
Any help will be appreciated.

Guys i have done it using filterRecord.
<ext:Parameter Name="rows" Value="Ext.encode(#{sampleGrid}.getRowsValues(
{
filterRecord : function (record) {
return (record.data.IsAssigned==false); }
})
)" Mode="Raw" >
</ext:Parameter>

I am not sure if it is best solution but give try.
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title></title>
<script>
function Test() {
var jsondata = Ext.encode(App.grd.getRowsValues());
alert("{dt:" + jsondata + "}");
var mynewitems = {};
var myobj = JSON.parse('{"dt":' + jsondata +'}');
for (var i = 0; i < myobj.dt.length; i++) {
alert(myobj.dt[i].data2);
if (myobj.dt[i].data2 == true) { myobj.dt.splice(i, 1); }
}
alert(myobj);
return myobj;
}
</script>
