Question:
Hope this will be understandable. Going to simplify the code alot.
I have a Master page, then i have Default.aspx. In this Default page i have the following.
<asp:Content ID="Content2" ContentPlaceHolderID="CPH_Main" Runat="Server"> <asp:Panel ID="Panel1" runat="server"> </asp:Panel> </asp:Content> Ok, so i have a class in the App_Code folder. Lets say that on page_load on default.aspx i start a function that is called "Populate_Content". I start it with giving it two parameters, the Panel which the items should be at and a ID to select from db. So it goes like this Populate_Content(Panel1, 4)
The function selects from the db and at runtime makes Linkbuttons and adding them to the Panel1, it also gives them a eventhandler for the click event.
The problem is that I'm trying to get the "Populate_Content" function to work in the clickevent that is stored in the App_Code folder. How can i select the control (Panel1) in the class file that is inside the App_Code folder. I can get the id of the selected linkbutton with this approach
//This the class inside App_Code void description_Click(object sender, EventArgs e) { string id = ((LinkButton)sender).ID.ToString(); //Then i need to do this.. but i need to find the "Panel1" controller //Populate_Content("Panel1", id); } But i need to start the "Populate_Content" in the click event also. So i need the to find the "Panel1" controler that is in the default.aspx.
I have tried to use the page property on the sender like so. But no go.
Page def_page = ((LinkButton)sender).Page; Panel panel1 = (Panel)def_page.FindControl("Panel1"); I though the page property would give me the page where the controller is, i cant find anything about this on google.
Am I doing this wront or is there another way ?
Edit: This the Populate_content
public void Populate_content(Panel cont, string treenode) { var query = from n in dc.Nemanet_Navigations where n.UserId == userGuid && n.Nav_pID.ToString() == treenode orderby n.Nav_Name select n; foreach (var item in query) { if (item.Nav_IsFile == true) { Panel div = new Panel(); div.CssClass = "BulletDiv"; cont.Controls.Add(div); Image picture = new Image(); picture.ImageUrl = "~/Icons/Nytt_skjal.png"; div.Controls.Add(picture); div.Controls.Add(new LiteralControl("<br/>")); LinkButton description = new LinkButton(); description.Text = item.Nav_Name; description.ID = item.Nav_ID.ToString(); description.Click += new EventHandler(description_Click); div.Controls.Add(description); } else if (item.Nav_IsFile == false) { Panel div = new Panel(); div.CssClass = "BulletDiv"; cont.Controls.Add(div); Image picture = new Image(); picture.ImageUrl = "~/Icons/Ny_mappa.png"; div.Controls.Add(picture); div.Controls.Add(new LiteralControl("<br/>")); LinkButton description = new LinkButton(); description.Text = item.Nav_Name; description.ID = item.Nav_ID.ToString(); description.Click += new EventHandler(description_Click); div.Controls.Add(description); } } }
