custom control Page_init and page_load seem to run twice 

Hi Guys

Im building a custom control and it seems that my page_init and page_load functions seem to run twice.  would there be any explanation for that?  i have never developed controls outside of DNN before so i dont know if this is standard procedure.

i have a routine that i run from page_init that adds columns to a datagrid, because of this phenomenon it adds twice as many columns as necessary because it adds them twice (each time page_init is run)

Please help me!

Re: custom control Page_init and page_load seem to run twice 

Hi quintin79,

I don't know why but sometimes .NET calls the Page_Load and Page_Init twice, when they are inherited from Page.
Try to use overwriting onLoad and onInit (with base calls to MyBase.onLoad and Mybase.OnInit) instead of using Page Events. That has helped me in the past and the events are now called only once.

Before:
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

After:
Protected Overrides Sub OnLoad(ByVal e As System.EventArgs)
    MyBase.OnLoad(e)
