Hi,

I have the following in Main.Master file:

C#

ViewState["member_id"] = Convert.ToString(sql_reader["member_guid"]);

and in banner.ascx which is embedded in the Main.Master, I have the following:

HTML

<a href="<%# String.Format("{0}/{1}", Page.RouteData.Values["ADDRESS"], Eval("post_guid")) %>"><img src="<%# String.Format("{0}/{1}/posts/{2}/{3}.png", Application["MemberMediaDirectory"], ViewState["member_guid"], Eval("post_guid"), Eval("member_post_media_guid")) %>" alt="<%# Eval("member_post_media_title") %>" title="<%# Eval("member_post_media_title") %>" width="906px" height="360px" id="<%# Eval("member_post_media_id") %>"/></a>

but the ViewState["member_id"] is getting lost there and it's just blank! how can I fix it please?

Where are you assigning the view state at?

I think you have to assign the value in init in code behind, before page load.

If I remember correct, the webform elements load first, and then page.load fires in the page life cycle

Edit:

My mistake about the master page holding its own view state which is not shared. But I am correct about loaing the viewstate in page.init to hold its value during partial page post backs, and not page load

ViewState is not inherited by child controls. Anything you set in the master page will only be available in the master page.

If you want to share some state across the entire page, try the Page.Items[^] collection.
