This code for insert value into cboRegional

public List<PropertyFinance> obj = PropertyFinanceItemItem.GetDataAll();
protected void Page_Load(object sender, EventArgs e)

if (!X.IsAjaxRequest)
List<Ext.Net.ListItem> licol = new List<Ext.Net.ListItem>();
var cboObj = obj.Select(x => x.KODE_REGIONAL).Distinct().OrderBy(x => x);

foreach (var item in cboObj)
licol.Add(new Ext.Net.ListItem(item, item));
licol.Insert(0, new Ext.Net.ListItem("All", "All"));
cboRegional.Value = "All";

protected void GHRefresh(object sender, StoreReadDataEventArgs e)
string xyz = this.cboRegional.SelectedItem.Text; // result = null
xyz = this.cboRegional.Text; // result =''

how to get value string of cboRegional?

Hi @opacjkt,

Please provide a full test case to reproduce the issue

Meanwhile, is there a <form runat="server"> on the page?
