Drag Drop Cell content

[Officialboss]

Hello,

I am exploring the Drag and Drop feature of the RadGrid. Can I drag and drop the Cell content (numeric value) of RadGrid1 to a cell in RadGrid2? Could you please direct me a sample that demonstrate this?

Thanks.

The cell in RadGrid where I want to drop the numeric value will have a template column with a TextBox.

Anyone tried this in their projects?

Hi Howard,

With RadGrid's items drag and drop functionality, you can move only the entire griddataitems. If you want only cells to be drag and dropped you may consider implementing custom drag and drop functionality. I have attached a page with very basic implementation of the desired behavior to get you started. Please feel free to modified it to better suite your needs.

Best wishes,

Hello,

A few follow up questions from your example:

var currentElement = Telerik.Web.UI.Grid.GetCurrentElement(e);

Referring to the line above, what other elements of the Grid can I get?
I want to restrict the column of the source grid the value can be dragged from.

After dragging the value of a Cell in RadGrid1(source grid) and running a validation and a successful droping into the destination(RadGrid2) how do I disable the original value that was just dragged, to prohibit from being dragged again?

Thanks

Hello Howard,

The GetCurrentElement function is use for getting the element which is the source of the raised dom event. Therefore this can be any element.

In order to restrict which columns can be dragged, you can check if the dragged cell belongs to a column with certain UniqueName.

To your last question. You can mark the cell which was dragged and then check for this mark when user tries to move it again.

I have attached a modified version of the page in order to demonstrate the above suggestions.
