  Hi Samir,

  Thank you for writing.
  
  Before getting to your question, we would like to check something related to your license. Your account shows no purchases and it seems that you have not downloaded the WinForms suite from our site. Since it is our policy to support users in good account standing, I will ask you to give us more details on the license you are using:

  - In case you have downloaded it from another site, please let us know so that we can update your account and provide you with proper support services;
  - In case you have obtained a copy of our controls through the company you work for, please ask the purchase holder to add you as a License Developer to the purchase. This will give you full access to the products your company has purchased, to our downloads section, and to our support ticketing system. Additionally, all your questions will be reviewed according to the license you have. More information on License Developers you can find here: www.telerik.com/faq.

  I have moved your Forum post to our support ticketing system to avoid sharing any private information in the public Forums. You can find the ticket in Your Account.
  
  As to your first question, I would kindly ask you to provide some more details such as, which Telerik controls are you using to drag from / to and which demo are you referring to. It would also be very helpful if you can prepare a sample project where you reproduce the unwanted behavior and an explanation of what the proper behavior is.
  
  On your second question. You can add an extra column in your DB table, storing the items. In this extra column you can save the order in which you want to display the items. When you visualize the items later you need to just order them by this extra column.
  
  I have converted your forum post to a support ticket so you can add an attachment.
  
  I am looking forward to your reply.

  Hello,
  
  I have added drag and drop control, but i cannot do following two things, please help me on that
  
  1) When i drag any item from right to left, then I cannot drag the same item from right to left. I have checked in the Demo of this , but its also having same problem, in the demo they provide Recyclebin, to delete, but my client doesn't want this...He just Drag from Left to right same way from Right to Left
  
  And second one
  
  2) Also When i drag from Left to right, i need to Rearrange the Items on the Right and save this ordering arrangment in to DB, so that i will show in this saved order on my other website...

Hi Samir,

Regarding your first question:

In order to achieve the desired functionality concerning drag-drop from the right grid to the left you need to implement the same logic as the logic for dragging left to right. For example on the mentioned demo the client onRowDropping event is canceled if the sender is not grdPendingOrders or the item from the right grid is not moved to the recycle bin:

function onRowDropping(sender,args) {

if(sender.get_id()=="<%=grdPendingOrders.ClientID %>") {

   ....

  }

else {

         ....

if(!isChildOf('trashCan',node)) {

args.set_cancel(true);

        }


          ....

       }


     }


Also on the server you need to implement logic for inserting item into the data source of the left grid into the grdShippedOrders_RowDrop event handler (similar to the logic into grdPendingOrders_RowDrop event handler).

Regarding your second question:
You could use the approach suggested by my colleague Ivan Petrov. You can add an extra column in your database table which keeps the order of all items. When the row is dropped from one grid to another you could change the values in this column and show the items in the order which you want.

Please give the suggestions try and let me know if you experience any problems.
