[CLOSED] Proxy Handler start twice when in C# we are change PageIndex
For example we have proxy method: https://examples1.ext.net/#/GridPane...rting/Handler/
Now I will supplement some parts of the code:
We can trace it in Output window
What it is possible to do, if only proxy only one time started itself?
Now I will supplement some parts of the code:
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
this.Store1.BaseParams["session_name"] = "test";
this.PagingToolbar1.PageIndex = 2;
this.CheckboxSelectionModel1.SelectedRows.AddRange(
new SelectedRowCollection()
{
new SelectedRow("3"),
new SelectedRow("5"),
new SelectedRow("7"),
new SelectedRow("10"),
new SelectedRow("15")
}
);
}
</script>
