Dynamically loading user control is ok, it works great, but I can't pass a parameter to user control, it gives me

CS0117: 'System.Web.UI.Control' does not contain a definition for 'nameFile'

error

here is the code;


		//STage'i oluştur
		Control TemplateStage = LoadControl("../ucx/Template.Stage.SWFObject.ascx");
		Controls.Add(TemplateStage);
		TemplateStage.nameFile = itemString;
		stageContent.Controls.Add(TemplateStage);
		stageContent.Visible=true;

have you declared nameFile as a public property in your usercontrol as below ?

private string _nameFile;

public string nameFile //property
{
set { _nameFile = value; } //write into property
}

also, you will run into problems adding the same usercontrol to two different control sets, you should instantiate a second copy to add it to the second control, and you should also load it using the tagname that is set in your tag declaration not using the generic Control type, which is possibly the source of your problem. see example below.

PostingOptions POt = (PostingOptions)Page.LoadControl("~/User_Controls/PostingOptions.ascx");
POt.TopicId = TopicId;
POTop.Controls.Add(POt);

PostingOptions POb = (PostingOptions)Page.LoadControl("~/User_Controls/PostingOptions.ascx");
POb.TopicId = TopicId;
POBottom.Controls.Add(POb);
