Let's say I have multiple rows in a RadGrid. One of the column is a GridDropDownColumn. The RadGrid is in "all-rows-edit-mode".

Is there any way that I can filter each instance of the GridDropDownColumn, based on, for instance, the key-value of the respective row, without using load-on-demand?

For instance, consider a grid with two columns "Type" and "Instance".
The Type column is a readonly bound column, wheras Instance is a dropdown column.
There are three rows in the grid, where Type has the values "Animal", "Fruit" and "Vehicle". Now, I want the content of the three different dropdowns to be filtered based on the Type-value for the respective row.
In other words:
For row "Animal", the dropdown shows "Cat", "Dog", etc
For row "Fruit",  the dropdown shows "Apple", "Pear", etc
For row "Vehicle",  the dropdown shows "Car", "Bus", etc

Can this be done without using load-on-demand (which would complicate things a lot in our case)?

Thanks!
/Fredrik

Hello Fredrik,

You can pass a separate datasource to the dropdown, which is related to the item currently being databound for the grid.
