Different DropDownProvider data items for each grid row?
posted

I have a WebDataGrid with 2 columns, A & B.

Column A is readonly.

Column B has a DropDownProvider to pick the value.

I want the data items in B to be dependent on the value in A. So for example:
If A = 1, then B = {red, pink, salmon}
If A = 2, then B = {blue, cyan, turquoise}
etc.

I have gotten the behavior I want using Load-on-Demand on column B, i.e: loadItems(A.value, false).
However, this forces me to Load-on-Demand each time I open the drop down which makes the UI a bit slow.

Is there a better way to do this? Maybe use Load-on-Demand, but somehow cache the results on the client side? Any ideas?

    Hi ssd,

    If I understand you right, you have readonly column A and Column B, which is dependable on the column A value. So once the data is loaded in the Grid, no matter what I choose from the drop down, the values in the drop down won't be changed? then why you will load them on every selection changesd of the drop down??

    Maybe I don't understand you right, but can you send us a sample, with code to acquire better vision of your problem

    Thanks,
