Hello,

I have create a Azure Cloud Service with WCF where i am trying to list my containers and blobs. I've been able to list both my containers and blobs. What i am trying to do is that when i select a container in my ListBox, it will display the blobs it contains in another ListBox.

When my project is load, my containers are already lusted in my ListBox 2. What i am trying to do is that when i click on a specific container, it will display its content in another ListBox1.

What I have tried:

The code for listing my Containers:

public List<string> ListContainer()
{
List<string> blobs = new List<string>();

// Retrieve storage account from connection string.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("BlobConnectionString"));

// Create the blob client.
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference("mycontainer");

//Get the list of the blob from the above container

IEnumerable<cloudblobcontainer> containers = blobClient.ListContainers();

foreach (CloudBlobContainer item in containers)
{

blobs.Add(string.Format("{0}", item.Uri));
}

return blobs;
}


The code for listing my Blobs:

public List<string> ListBlob(string folder)
{
List<string> blobs = new List<string>();

// Retrieve storage account from connection string.
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
CloudConfigurationManager.GetSetting("BlobConnectionString"));

// Create the blob client.
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

// Retrieve reference to a previously created container.
CloudBlobContainer container = blobClient.GetContainerReference(folder);


//Get the list of the blob from the above container
IEnumerable<ilistblobitem> blobList = container.ListBlobs();

//Display the names on the page
string names = string.Empty;

foreach (IListBlobItem item in blobList)
{
blobs.Add(string.Format("Directory {0}", item.Uri));
}


Finally, this is the code i set in my ListBox so that when i select the item "mycontainer" or "test" it will display its content in the ListBox1.

protected void ListBox2_SelectedIndexChanged(object sender, EventArgs e)
{
if (ListBox2.SelectedItem.ToString() == "mycontainer")
{
BlobService list = new BlobService();
ListBox1.DataSource = list.ListBlob("mycontainer");
ListBox1.DataBind();
}
else if (ListBox2.SelectedItem.ToString() == "test")
{
BlobService list = new BlobService();
ListBox1.DataSource = list.ListBlob("test");
ListBox1.DataBind();

}

It is not working and i really don't know what to do! Hope you can help me!
