Drag and Drop Cell

[Derrick]

I'm working with the Item Drag and Drop sample, and it works very well.  However, I have modified it slightly.  The source datagrid has a different number of columns than the destination datagrid.  I have modified the code so that when the item is dropped, I manually add the row to the grid.  That all works fine, but I really would like to know which column the item was dropped on.  Is there a way to get this information?

Thanks,
Derrick.

Hello Derrick,

I'm afraid the this scenario is not supported out-of-the-box. However this can be accomplished  with few lines of javascript. You should hook to client-side onRowDropping event and retrieve the column's uniqueName. Similar to this:

function onRowDropping(sender, args)
{
   //get the first row element
    var row = Telerik.Web.UI.Grid.GetFirstParentByTagName(args.get_destinationHtmlElement(), "tr");
    //check if the row element is gridDataItem and if the destination element is a tablecell
    if(!row || row.id == "" || args.get_destinationHtmlElement().tagName.toLowerCase() != "td")
        return;
    //retrieve the GridTableView's object
    var tableID = row.id.split("__")[0];
    var tableView = $find(tableID);

    //get the cell's uniqueName
    alert(tableView.getColumnUniqueNameByCellIndex(tableView.HeaderRow, args.get_destinationHtmlElement().cellIndex));
}

Let us know if this help or you need further assistance.

Rosen,

Thanks for your response.  I tried the javascript you provided, and it works well.  However, is it possible to get this information on the server-side?

Thanks,
Derrick.

Hi Derrick,

You can try saving the column's UniqueName inside a hidden field and then retrieve is on the server.

Hello,

I am using the Grid's client-side method "GetFirstParentByTagName" and it works great.  I am looking for similar methods to traverse the Grid.  However, I cannot find any documentation on the available methods.  Where is "GetFirstParentByTagName" in your documentation of the Grid. 

Thanks.

Hello Feizal,

There is not any detailed documentation on this method, but the sample posted earlier demonstrates its usage.
Additionally, I will make sure there is additional information added about this method.

Sincerely yours,

Thanks for the information.  I am wondering if there are any other methods similar to "Telerik.Web.UI.Grid.GetFirstParentByTagName".  Specifically, what I want to do is have a command button at the top of the grid and find all children of the grid with a specified tag.

Thank You.

Hello Feizal,

Presently, there is no such method available.
You can use pure JavaScript, to iterate through the elements for any tag - parent or child, or the elements on the page.

Hi Feizal Amlani,

Thank you for your interest.
 
I would suggest that you try our RadScheduler control that can fit in your scenario. In addition, our RadGridView control supports drag & drop, please consider the GridView >> Rows >> Rows Drag & Drop example in our demo application. Please elaborate a bit more and describe in detail your scenario. This will help me to be more accurate in my suggestions.

I am looking forward to your reply.

All the best,
Jack
