<ext:ListItem Text="Slickness" Value="ExtJS/resources/css/xtheme-slickness.css" />
</Items>
</ext:ComboBox>
client side script:
<script language="javascript">
var ChangeTheme=function(tabPanel,theme)
{
Coolite.Ext.setTheme(theme.getValue());
tabPanel.items.each(function(el) {
if(!Ext.isEmpty(el.iframe))
{
el.iframe.dom.contentwindow.Coolite.Ext.setTheme(t heme.getValue());
}
});
}
</script>
server side script:
// save the value to db.
protected void SetThemeSession(object sender,EventArgs e)
{
OATheme.SetTheme(this, ddl_Theme.SelectedItem.Value);
}
//and initiate the theme
protected void Page_Load(object sender, EventArgs e)
{
string myTheme = OATheme.GetTheme(this);
for (int i = 0; i < ddl_Theme.Items.Count; i++)
{
if (ddl_Theme.Items[i].Value == myTheme)
{
ddl_Theme.SetValueAndFireSelect(myTheme);
break;
}
}
}
in others pages' page_load method:
protected void Page_Load(object sender, EventArgs e)
{
//select the theme from db and set the page's theme.
OATheme.GetTheme(this);
}
hope this helps
