       XmlDocument xmldoc = new XmlDocument();
       xmldoc.Load(Server.MapPath("~/" + "XML/album.xml"));
       XmlNodeList nodelist = xmldoc.GetElementsByTagName("Album");
       DataTable dt = (DataTable)Session["dt"];
       if (dt.Rows.Count > 0)

           for (int i = 0; i < nodelist.Count; i++)
           {
               string val = e.CommandArgument.ToString();

               string attr = nodelist[i].Attributes["Name"].Value;
               if (attr == val)
               {

                   {
                      string imgpath=nodelist[i].InnerText;

                       DirectoryInfo directoryInfo = new DirectoryInfo(imgpath);
                       FileInfo[] fileInfo = directoryInfo.GetFiles();

                       images.Add(fileInfo[j].Name);
                   }

                   Repeater2.DataSource = images; // i am getting image name here

Hi,

What do you see when the repeater is rendered? What path is being rendered in the HTML for each row? Is that path correct for an image? I am guessing it isn't. Please let me know.

I am getting path and images from the folder but yet it is not getting display

DataTable imgdt = new DataTable();
for (int j = 0; j < count; j++)
{
string imgpath=nodelist[i].InnerText; // here i am getting path of the folder

DirectoryInfo directoryInfo = new DirectoryInfo(imgpath);
FileInfo[] fileInfo = directoryInfo.GetFiles();

images.Add(fileInfo[j].Name); // here i am getting images in that folder.

}

Repeater2.DataSource = images; // i am getting image name here
Repeater2.DataBind();
}

This is all right. I am more interested in the HTML that is rendered. Can you please do a
'view->source' on the browser where the repeater is displayed and paste the HTML portion for the repeater only?

sumit kausalye 3-Feb-14 3:52am

Sir i just see a blank repeater control. no images are added in that repeater control.

sumit kausalye 3-Feb-14 3:55am

Sir i guess i have make changes in image tag in design view. but what should i add to bind dynamic path to image control.

CoderPanda 3-Feb-14 4:10am

You shouldn't have to make anything in the design view. I still want to see the HTML that is rendered when you run the app. So far you have only given me the server side code.

When you run the app, go to the browser and get the HTML for the empty repeater. It should be a HTML table.

Okay. So the problem here is src="". It should have the path of an image.

Can you please check if the following lines of code are having any values while debugging? Put a break point on those lines and see if correct paths are being formed.
string imgpath=nodelist[i].InnerText;
and
images.Add(fileInfo[j].Name);

From then on you have to keep going backwards and see where the file name isn't coming into the image array properly.

i checked sir it is showing proper path and image name also.

CoderPanda 3-Feb-14 5:11am

I still doubt that the images array has all the data. If it really does then may be the repeater is supposed to be bound differently.

Try using #Eval(Container.DataItem.ToString()) instead of #Container.DataItem
