I have just finish to apply themes dynamically and I want to share my experience.
1. I added a dropdown list to my Default.master file
2. I wrote theme class in to the App_Code folder
|
public class Theme{ private string _name; public string Name { get { return _name; } set { _name = value; } } public Theme(string name) { Name = name; } } |
3. I created theme manager class
|
using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Collections; using System.Collections.Generic; using System.IO; /// <summary> /// Summary description for ThemeManager /// </summary> public class ThemeManager { #region Theme-Related Method public static List<Theme> GetThemes() { DirectoryInfo dInfo = new DirectoryInfo(System.Web.HttpContext.Current.Server.MapPath("App_Themes")); DirectoryInfo[] dArrInfo = dInfo.GetDirectories(); List<Theme> list = new List<Theme>(); foreach (DirectoryInfo sDirectory in dArrInfo) { Theme temp = new Theme(sDirectory.Name); list.Add(temp); } return list; } #endregion } |
4. I added a object datasource to default.master
|
<asp:ObjectDataSource ID="ThemeDataSource" runat="server" SelectMethod="GetThemes" TypeName="ThemeManager" ></asp:ObjectDataSource> |
5. Then I wrote the methods listed below
|
protected void lstTema_DataBound(object sender, EventArgs e) { lstTema.SelectedValue = Page.Theme; } protected void lstTema_SelectedIndexChanged(object sender, EventArgs e) { Session.Add("MyTheme", lstTema.SelectedValue); Server.Transfer(Request.FilePath); }
|
6. I created BasePage class
|
using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; /// <summary> /// Summary description for BasePage /// </summary> public class BasePage:System.Web.UI.Page { protected override void OnPreInit(EventArgs e) { base.OnPreInit(e); if (Session["MyTheme"] == null) { Page.Theme = "Black"; } else { Page.Theme = ((string)Session["MyTheme"]); } } } |
7.And after all I inherit all the pages from this class.
|
public partial class Default_aspx : BasePage { } |
Thats All.
