Dynamically set path

[dipan]

Hi I am trying to change FileExplorer path dynamically but its not getting change. I have one dropdown box and based on selected item I am trying to change the File Explorer path Dynamically.  Please see my code below:

<div class="settings">

        <h1>Media Libraries</h1>

        <div>

            <fieldset style="width: 250px;">

                <legend>Choose a Site</legend>

                <telerik:RadComboBox ID="ddlSite" runat="server" Width="200px" Height="100px" AutoPostBack="true"

                    EmptyMessage="Select a Site" EnableVirtualScrolling="true" OnSelectedIndexChanged="ddlSite_SelectedIndexChanged">

                </telerik:RadComboBox>

            </fieldset>

        </div>

        <div>

        <fieldset style="width: 250px;">

                <legend>Selected Site</legend>

                <asp:Label ID="lblSiteName" runat="server" Text=""></asp:Label>

            </fieldset>

        </div>

    </div>

    <table cellspacing="4" cellpadding="0" border="0" style="padding-left:10px;" >

        <tr>

            <td style="vertical-align: top;">

                

                <telerik:RadFileExplorer runat="server" ID="FileExplorer1" Width="1000px" Height="500px"

                    OnClientItemSelected="OnClientItemSelected" >

                </telerik:RadFileExplorer>

            </td>

            <td valign="top">

                <fieldset style="width: 230px; height: 220px">

                    <legend>Preview</legend>

                    <img id="pvwImage" src="" runat="server" alt=""

                        style="display: none; max-width:230px; max-height:220px; margin: 10px;  vertical-align: middle;" />

                </fieldset>

            </td>

        </tr>

        </table>

 

.cs page:

 

        protected void Page_Load(object sender, EventArgs e)

        {

            InitializeContainer();

            //set properties according to configuration panel

            FileExplorer1.VisibleControls = GetVisibleControls();

            FileExplorer1.EnableOpenFile = true;

            FileExplorer1.DisplayUpFolderItem = true;

            FileExplorer1.AllowPaging = true;

            FileExplorer1.EnableCreateNewFolder = true;

            FileExplorer1.Upload.Enabled = true;

            //if (!enableUpload.Checked)

            //{

            //    FileExplorer1.Configuration.UploadPaths = new string[0];

            //}

            if (!IsPostBack)

            {

                BindSite();

                lblSiteName.Text = ddlSite.SelectedItem.Text;

                 

                

                ////Set initial folder to open. Note that the path is case sensitive!

                FileExplorer1.Configuration.ContentProviderTypeName = typeof(CustomColumnsContentProvider).AssemblyQualifiedName;

                //FileExplorer1.InitialPath = Page.ResolveUrl(String.Format("~/SiteData/{0}/UserFiles/allowed.png",this.SiteID));

                this.SiteID = Convert.ToInt32(ddlSite.SelectedValue);

                string PagePath = Page.ResolveUrl(String.Format("~/SiteData/{0}/UserFiles/allowed.png", this.SiteID));

                string RootPagePath = Page.ResolveUrl(String.Format("~/SiteData/{0}/UserFiles", this.SiteID));

                //Set initial folder to open. Note that the path is case sensitive!

                // FileExplorer1.InitialPath = PagePath;

                FileExplorer1.Configuration.ViewPaths = new string[] { RootPagePath };

                FileExplorer1.Configuration.UploadPaths = new string[] { RootPagePath };

                FileExplorer1.Configuration.DeletePaths = new string[] { RootPagePath };

                 

            }

            

            AddDateAndTypeColumns();

        }

 

 protected void ddlSite_SelectedIndexChanged(object sender, EventArgs e)

        {

            lblSiteName.Text = ddlSite.SelectedItem.Text;

            this.SiteID = Convert.ToInt32(ddlSite.SelectedValue);

 

            string RootPagePath = Page.ResolveUrl(String.Format("~/SiteData/{0}/UserFiles", this.SiteID));

            //Set initial folder to open. Note that the path is case sensitive!

            // FileExplorer1.InitialPath = PagePath;

            FileExplorer1.Configuration.ViewPaths = new string[] { RootPagePath };

            FileExplorer1.Configuration.UploadPaths = new string[] { RootPagePath };

            FileExplorer1.Configuration.DeletePaths = new string[] { RootPagePath };

        }

Thanks in advance for your help....

Hi dipan,

Would you mind posting the solution you found?  I'm having the same problem.

Thank you!!

Hi Lori,
The way I made it work is:
configure your file explorer in seperate function:

protected void ConfigureFileExplorer()
        {
            FileExplorer1.VisibleControls = GetVisibleControls();
            FileExplorer1.EnableOpenFile = true;
            FileExplorer1.DisplayUpFolderItem = true;
            FileExplorer1.AllowPaging = true;
            FileExplorer1.EnableCreateNewFolder = true;
            FileExplorer1.Upload.Enabled = true;

            this.SiteID = Convert.ToInt32(ddlSite.SelectedValue);
            string PagePath = Page.ResolveUrl(String.Format("~/SiteData/{0}/UserFiles/allowed.png", this.SiteID));
            string RootPagePath = Page.ResolveUrl(String.Format("~/SiteData/{0}/UserFiles", this.SiteID));
            string RootSharedFolder = Page.ResolveUrl("~/SiteData/SharedFolder");
            FileExplorer1.TreeView.Nodes.Clear();
            FileExplorer1.InitialPath = RootPagePath;
            FileExplorer1.Configuration.ViewPaths = new string[] { RootPagePath,RootSharedFolder};
            FileExplorer1.Configuration.UploadPaths = new string[] { RootPagePath,RootSharedFolder};
            FileExplorer1.Configuration.DeletePaths = new string[] { RootPagePath,RootSharedFolder};
            FileExplorer1.Configuration.MaxUploadFileSize = 20480 * 1024; // 20 MB
            FileExplorer1.Configuration.SearchPatterns = new string[] { "*.*" };
            FileExplorer1.PageSize = 20;

            FileExplorer1.Configuration.ContentProviderTypeName = typeof(CustomColumnsContentProvider).AssemblyQualifiedName;


            AddDateAndTypeColumns();
            AddCustomDownloadOption();
        }

then in page load

 protected void Page_Load(object sender, EventArgs e)
        {
            InitializeContainer();
            //set properties according to configuration panel


            if (!IsPostBack)
            {
                BindSite();
                lblInstruction.Text = "<ol><li>Choose a site to upload files.</li><li>To upload multiple files create a zip file and upload, it will unzip automatically.</li><li>Maximum upload file size 20MB.</li><li>Click on image to see the preview.</li></ol>";
            }

            lblSiteName.Text = ddlSite.SelectedItem.Text;
            ConfigureFileExplorer();
        }

and set the dropdown seleted value in dropdown selectedIndexChanged event
 protected void ddlSite_SelectedIndexChanged(object sender, EventArgs e)
        {
            lblSiteName.Text = ddlSite.SelectedItem.Text;
            this.SiteID = Convert.ToInt32(ddlSite.SelectedValue);
        }

Hello,

The latest moment of the page lifecycle that ViewPaths, UploadPaths, DeletePaths properties can be configured to RadFileExplorer is the Page_Load event, and the Button_Click event occurs after that.

The recommended approach to set RadFileExplorer dynamically according another controls' action / value is:

• In the Page_Load you need to check which control causes postback
• Then, change the paths based on the clicked button. Please note that you need to clear the old nodes in order to force the RadFileExplorer to repopulate its content.

Please find attached to this post a sample page demonstrating the above mentioned approach.

Kind regards,

Hi, I am trying to do the same thing - change RadFileExplorer path dynamically. The issue I have is I need to change it to network folder(\\server\c$\dir\...)
I got the error below:
System.InvalidOperationException: Failed to map the path '/server/c$/dir/...

"\\" in my code is changed to "/" 
Any advice?

Hi Steve,

In order to browser shared network folders using RadFileExplorer you need to implement custom filebrowser content provider. An example of such content provider is available in the following KB article:
Use RadFileExplorer with physical and shared folder's paths
