- Description:

When drag a dataset column into layout:

Search the target container, if container has the same dataset, add the column binding if it does not exist in the container.
If the container's dataset is not the dragged dataset column's dataset, column binding will be added to the new dataitem, and set dataitem's dataset with the dragged dataset column's dataset.
If the container is not bound with a dataset, then set the container’s dataset with the dragged dataset column's dataset, and add column binding to the container.
