Hi Daniil,
It is working if we add DataSource as object array. Why the values are not showing if we assign DataTable as DataSource as in example below...
<%@ Page Language="C#" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!X.IsAjaxRequest)
{
cboValue.Items.Add(new Ext.Net.ListItem("val1", "1"));
cboValue.Items.Add(new Ext.Net.ListItem("val2", "2"));
cboValue.Items.Add(new Ext.Net.ListItem("val3", "3"));
cboValue.Items.Add(new Ext.Net.ListItem("val4", "4"));
//this.Store1.DataSource = new object[]
//{
// new object[] { "1","test1", "2", "test3" },
// new object[] { "2","test4", "test5", "test6" },
// new object[] { "3","test7", "4", "test9" },
// new object[] { "4","test10", "test11", "test12" }
//};
//this.Store1.DataBind();
this.Store1.DataSource = GetDataInfo();
this.Store1.DataBind();
}
}
public DataTable GetDataInfo()
{
DataTable dt = new DataTable();
DataRow dr;
dt.Columns.Add("TestID");
dt.Columns.Add("test1");
dt.Columns.Add("test2");
dt.Columns.Add("test3");
dr = dt.NewRow();
dr[0] = "1";
dr[1] = "test1";
dr[2] = "2";
dr[3] = "test3";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[0] = "2";
dr[1] = "test4";
dr[2] = "test5";
dr[3] = "test6";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[0] = "3";
dr[1] = "test7";
dr[2] = "4";
dr[3] = "test9";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[0] = "4";
dr[1] = "test10";
dr[2] = "test11";
dr[3] = "test12";
dt.Rows.Add(dr);
return dt;
}
protected void Store_BeforeStoreChanged(object sender, BeforeStoreChangedEventArgs e)
{
string jsonData = e.DataHandler.JsonData;
X.Msg.Alert("Saved", jsonData).Show();
}
