Custom folder name in Azure

[Tomasz]

Hi,

I want to create a simple upload mechanism to Azure. I want to have a text field whre the user will enter some text and that text will became the folder name in Azure storage for that upload.



How it would be recomended to do?

Hi Tomasz,

This can be done with query string, which you pass to the custom handler. For example:

<telerik:RadCloudUpload ID="RadCloudUpload1" runat="server" ProviderType="Azure"
    MultipleFileSelection="Automatic" OnClientFileSelected="onClientFileSelected"
    HttpHandlerUrl="~/UploadToCarsFolderHandler.ashx">
</telerik:RadCloudUpload>

<script type="text/javascript">
    function onClientFileSelected(sender, args) {
        var customParam = "test";
        sender._module._handlerUrl = "/UploadToCarsFolderHandler.ashx?type=rcu&customParam=" + customParam;
    }
</script>

public override void SetKeyName(object sender, Telerik.Web.UI.CloudUpload.SetKeyNameEventArgs e)
{
    var carsFolder = HttpContext.Current.Request["customParam"] + "/";

    e.KeyName = string.Format("{0}{1}_{2}", carsFolder, Guid.NewGuid(), e.OriginalFileName);
}

Sample is attached.

But doesn't the SetKeyName method set the file name?

Let's say I have:

http://mydomain.blob.core.windows.net/mycontainer/

and now during upload I want to have such a structure created:



http://mydomain.blob.core.windows.net/mycontainer/folder_specified_by_the_user_in_text_field/original_file_name.extension

Hi Tomasz,

The SetKeyName method specifies both the folder path and the file name. For example:

public override void SetKeyName(object sender, Telerik.Web.UI.CloudUpload.SetKeyNameEventArgs e)
{
    var carsFolder = HttpContext.Current.Request["customParam"] + "/";
    e.KeyName = string.Format("{0}{1}", carsFolder, e.OriginalFileName);
}

Great :)

Whenever I attempt this it just concatenates the container name and blob name together and puts the blob in the configured container folder in web.config. Any Ideas, using all latest Builds with VS 2013

Hi TheLostLeaf,

What is the the value of the e.KeyName after you change it?
