ok. are you able to get correct image path with name in your code without displaying to datalist?
Chinni13y ago

Iftikar Hussain13y ago

Two pages in the application are one home and the next one sub Home. Home page have two text boxes and two radio buttons in the first text box for main folder name in image folder, the second text box for sub folder name like flowers/rose flower is main folder in image folder rose in sub folder of flower this is folder structure now these two names assign to session and find the location of the folder if folders are available in image folder then display the images in page this is the complete picture

what output you are getting? Still I am not clear which path you want to set it?
Chinni13y ago
not working same output
Iftikar Hussain13y ago
try like this

public string GetPath()
{
if (Session["strSrc"] != null)
{
string path = "~/Source/" + Session["strSrc"].ToString();
DirectoryInfo myImageDir = new DirectoryInfo(Server.MapPath(path));
return myImageDir.ToString();
}
else
{
return "";
}
}

//string ss; protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { if (Session["strSrc"] != null) { hdfsessionPath.Value = "../"+Session["strSrc"].ToString(); } else return; string path = "~/Source/" + Session["strSrc"].ToString(); DirectoryInfo myImageDir = new DirectoryInfo(Server.MapPath(path)); Session["dir"] = myImageDir.ToString(); //ss = Session["dir"].ToString() + "\\"; try { usergalleryDataList.DataSource = myImageDir.GetFiles(); usergalleryDataList.DataBind(); } catch (System.IO.DirectoryNotFoundException) { Response.Write(" alert('Error!');"); } } // GetPath(); } public string GetPath() { return Session["dir"].ToString(); } }

share me the code for GetPath()
Chinni13y ago
yes i removed from page load but same output i need to assign the path to like images/screen/{0} in my session variable have path like images/screen/
Iftikar Hussain13y ago
wrong, you need to call GetPath() from aspx not from page load
Iftikar Hussain13y ago
then call a method from aspx and build the path with your condition and return it

public string GetPath()
{
build your path and return it
}

just path only like images/screen/ i need to take file names from folder
Iftikar Hussain13y ago
then assign the path as images/screen/imagename.jpg to the session variable
Iftikar Hussain13y ago
you are not saving the path which you have entered in the textbox?
Iftikar Hussain13y ago
You need to use your application folder image path
Chinni13y ago
actual url is

<a href='<%# Eval("Name","images/screen/{0}")%>'rel="prettyPhoto[pp_gal]">
<img src='<%# Eval("Name","images/screen/{0}")%>' width="60"height="60" alt='<%# Eval("Name") %>' />

this is working but i need to dynamic path every time i entered my path in text box and check the path if path is available i assigned to session this is scenario
Sanjeeb Lenka13y ago
don't use physical path as when you deploy this it will show error.

create a image folder in solution and store the image into that and

use the code given by iftikar

Hi,
Have you saved your anchor and image url in database? try like this

' width="60" height="60" alt='<%# Eval("Name") %>' />
