Hi

Thanks for the replay, can you be more specific about your answer, I'm using the combo in a template column, and setting the data source to a function on the asp page, how can this function know which row currently being updated ?
Or if using your solution please give some more information,

Ziv,

You can use template columns to have a column with a combobox. And you can
use ItemDataBound event to populate the combobox with the data from the row.

Hi Again

First I'm using a dropdownlist, second the dropdownlist should be populated every row with different datasource depanding on value stored in the current row in a different column for example DB_Grip has column A and column B (DropDownList)
Column B on every row should have different values depending on the value in Column A

Thanks for the help

Ziv,

Looks like you are almost on the right track. What are you using as a
combobox? A DropDownList? What DataSource are you setting to a function?

In any case, I don't think you can databind the control you are using as a
combo, since you want to populate it from a datagrid row and not from any
separate data source. I think you can achieve what you want much easier in
ItemDataBound event. The event gets a parameter that contains a reference
to the datagrid item that is being databound. You should filter out the
header, the footer and process only data items. Data item is a data row from
your table. It contains a collection of cells. So, you have access to all
the cells on the current row. You can populate the combo control out of the
cell values.
