This happens because PagingToolbar doesn't listen 'clear' event sended when calling method removeAll. You can check it here in method bindStore:
http://docs.sencha.com/ext-js/3-4/so...-PagingToolbar.
You can override this behavior check following code:
<script runat="server">
protected void Store_RefreshData(object sender, StoreRefreshDataEventArgs e)
{
Store store = this.GridPanel1.GetStore();
object[] newVariable = new object[]
{
new object[] { "test1" },
new object[] { "test2" },
new object[] { "test3" },
new object[] { "test4" },
new object[] { "test5" },
new object[] { "test6" },
new object[] { "test7" },
new object[] { "test8" },
new object[] { "test9" }
};
e.Total = newVariable.Count(); ;
store.DataSource = newVariable.Skip(e.Start).Take(e.Limit);
store.DataBind();
}
</script>
