Setting DynaEdit Value at runtime

I have a DynaEdit column in my grid, with a default value of 0.  For one of the rows I would like to set the value to "1", and prohibit the user from changing that value.  All other cells in that column can retain the default value and behavior.

Is that possible?

If you want to prevent that the user edits the value, you'll need to ensure that for this cell no DynEdit control is rendered. You could do this by implementing the event OnGetCellType and for this specific cell set the cell type different from ctDynEdit
