I would like to add a set of images in a folder inside the RadPanelItem. The idea consists to have a repeater that populates the RadPanelItem and after that drag & drop them to in the MainPane.

How can I drag & drop that images to the MainPane? Have I use javascript or can I use telerik? How?

public class ImageName

{

private string filename;

public string FileName {

get { return filename; }

set { filename = value; }

}

using System;

using System.Collections.Generic;

using System.Linq;

using System.Web.UI;

using System.Web.UI.WebControls;

using System.IO;

namespace TestSVG

{

public partial class Main : System.Web.UI.Page

{

protected void Page_Load(object sender, EventArgs e)

{

string path = Server.MapPath("~/Images/QualityPic/");

List<string> stringList = Directory.GetFiles(path, "*.jpg").Select(f => Path.GetFileNameWithoutExtension(f)).ToList();

List<ImageName> iList = new List<ImageName>();

ImageName i;

foreach (string s in stringList)

{

i = new ImageName();

i.FileName = s;

iList.Add(i);

}

imageRepeater.DataSource = iList;

imageRepeater.DataBind();

}

protected void imageRepeater_ItemDataBound(object sender, RepeaterItemEventArgs e)

{

//Event triggered when this item is selected

if (((Repeater)sender).DataSource != null)

{

ImageName singleImage = (ImageName)e.Item.DataItem;

Button smallImage = (Button)e.Item.FindControl("smallImage");

smallImage.ID = smallImage.ID + singleImage.FileName;

smallImage.Attributes.CssStyle.Add("background-image", "Images/QualityPic/" + singleImage.FileName + ".jpg");

smallImage.Attributes.Add("onclick", "return smallImageJS_Click(" + singleImage.FileName + ");");

}

Hello Ryan,

As per you assumption the RadDock and RadSplitter do not have one and the same functionality and dragging from a SlidingPane to another RadPane is not an out-of-the-box provided functionality. Nevertheless, as my colleague Kate suggested in her previous reply, you can place a RadDockZone control inside a Sliding Pane in order to be able to drag the images (placed into dynamically created RadDocks) into another RadDockZone, placed inside your content RadPane.

For convenience, I am attaching a very simplified project demonstrating the above described approach. Feel free to extend it in order to fit your scenario best.

I hope you will find this solution helpful.

Kind regards,
Veselina Raykova
