Hello,
We are currently working on a kendo web project where we need to be able to have a button on a grid that opens a kendo modal window and then creates a custom viewmodel to be consumed by the current kendo window that can be passed into another kendo window. However, I can't seem to find a way to bind a ViewModel into the kendo window. Any help would be appreciated. Here is my code:
The problems that I know about are:

The problems that I know about are:
- I don't know where to bind the observable to the window.
- How to pass the same observable from window to window.

Hi Colin,
I checked your code and noticed the following issues:

I checked your code and noticed the following issues:
- There is no need to create a ViewModel (Observable object) from the dataItem.
vardataItem =this.dataItem($(e.currentTarget).closest("tr"));
The dataItem variable is already an observable object so you can bind the template directly to it.
- Do you need to update the modal Window content every time when the Command button is clicked? It looks like that the content is static, the only thing that changes is the dataItem to which the #locationFeeAmount input will be bound. Am I right?
In that case you do need to use a template at all, instead you may simply put the template content inside the #transaction div.
On click on the command button you should bind the #transaction element to the dataItem.
functionshowTransactionModal(e) {e.preventDefault();vardataItem =this.dataItem($(e.currentTarget).closest("tr"));kendo.bind($("#transaction"), dataItem);wnd.center().open();};
