[OPEN] [#1424] [4.2.0] Selection issue on Childgrid in rowExpander
Hi Guys
I have grid and a nested childgrid with CheckboxSelectionModel in both parent and childgrid , when i select parent grid row all the child grid row gets selected as well . This selection is not shown in selectionmodel() of the childgrid . So when i try to clear i cant clear them
What i need is prevent selection of childgrid items on selecting parent grid row
My Grid Code is below
HTML Code:
<%@ page language="C#" autoeventwireup="true" codefile="Default.aspx.cs" inherits="_Default" %>
<%@ register assembly="Ext.Net" namespace="Ext.Net" tagprefix="ext" %>

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript">
var template = '<span style="color:{0};">{1}</span>';
var change = function (value) {
return String.format(template, (value > 0) ? "green" : "red", value);
};
var pctChange = function (value) {
return String.format(template, (value > 0) ? "green" : "red", value + "%");
};
</script>
