Hi @timiteh,
The SelectionChange event fires even if there is no selection. How are you going to handle such a case? Maybe, it is better for you to use the Select event.
Anyway this example demonstrates a techique how to work with a DirectEvent's ExtraParams.
Example
<%@ 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)
{
Store store = this.GridPanel1.GetStore();
store.DataSource = new object[]
{
new object[] { "test1", "test11" },
new object[] { "test2", "test22" },
new object[] { "test3", "test33" }
};
}
}
protected void RowSelectionModel_Select(object sender, DirectEventArgs e)
{
X.Msg.Alert("RowSelectionModel_Select", e.ExtraParams["test1"]).Show();
}
</script>
