Posted By:Sasi Prabhu       Posted Date: July 06, 2011    Points: 40    Category: ASP.NET Controls    URL: http://www.dotnetspark.com  

below code shows how to Apply the Themes at Runtime in asp.net website or application
 


To List the Themes into RadioButtonList :


Protected void Page_Load(object sender,EventArgs e)

if(!IsPostBack) { System.IO.DirectoryInfo ThemeInfo=new System.IO.DirectoryInfo(Server.MapPath("App_Themes")); ThemeRadioButtonList.DataSource=ThemeInfo.GetDirectories(); ThemeRadioButtonList.DataTextField="Name"; ThemeRadioButtonList.DataValueField="Name"; ThemeRadioButtonList.DataBind(); } }

Set ThemeRadioButtonList AutoPostBack Property as True.

Store the ThemeName into Session for that

Protected void ThemeRadioButtonList_SelectedIndexChanged(object sender,EventArgs e)
{
Session["Theme"]=ThemeRadioButtonList.SelectedValue;
Server.Transfer(Request.FilePath);
}


To Apply Theme :

protected void Page_PreInit(object sender,EventArgs e)
{
try
{
Page.Theme=Session["Theme"].ToString();
}
catch(Exception ex)
{
Response.Write(ex.Message);
}
}
