Hi,
There is no such event.
I can suggest the following way.
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.ComboBox1.GetStore();
store.DataSource = new object[]
{
new object[] { "1", "item1" },
new object[] { "2", "item2" },
new object[] { "3", "item3" }
};
store.DataBind();
}
}
[DirectMethod]
public void OnTriggerClick()
{
X.AddScript("console.log('OnTriggerClick')");
}
</script>
