How to set a property in a user control

[J-T]

I have a aspx page which loaded different user contols based on the users'
entries.In one of my child user controls I have a property like below:

public String PostID
{
get
{
return (String) ViewState["PostID"];
}
set
{
ViewState["PostID"] = value;
}
}

Now from my aspx page (parent page) ,I'd like to se this propert so I can
maintain the PostID across multiple postbacks of my user control.How can I
do that?
Here is the way I load the child user control in my aspx page (parent page):

Control dynamicUC = null;

dynamicUC= LoadControl("~/PageControls/GetPostDetails.ascx");

dynamicUC.EnableViewState=true;

ViewState["PostID"]=postID;





Thanks a lot

You need to cast your dynamicUC to the specific type of the user control
(not shown below, so I have no idea)

((MyUserControlType)dynamicUC).PostID = postId;

since this is only one of multiple user controls and the only one to expose
the PostID field, you might want to make the userControl fetch the value
from a public property of the page (ie, go fetch it instead of setting it).

PostID = ((PageType)Page).PostID;

I didn;t get the second part.What do you mean by "Page" in PostID =
((PageType)Page).PostID;?? do you mean the Parent page or the userControl
page (child )).

Thanks
