Datagrid headaches

[Kevin]

Hi Al

I have two questions about a datagrid, I need to decide which way to go....

I have a datagrid that will show me all the entries in a table. When I click on any cell(actually I would prefer if It could rather select the whole row, where ever I click), I want the data in that datagrid to populate the corresponding textbaoxes on my form, so that the user can edit the values and save them back to the database, and the update the datagrid. How do I do this

Otherwise, what I would like to do is to cut out the populating of the corresponding textboxes and just have the datagrid here I could edit and add new rows, but there are some columns that are lookup columns eg, I have a Manufaturers table, that holds all the possible manufacturers, and a ManufacturersDe tail table that holds all the possible contacts for that Manufacturer, So I want to be able to select the manufacturer, then it must filter the possible contacts, but I don't know first of all how to implement the lookup functionality in the datagrid, or the filtering of one field based on the selection of
another field within a datagrid! I have no idea about how to do this. This would definitly be 1st prize, Please can somebody help me, I'm really stuck on this one.And obviously the data stored for the manufacturer/manufacturerDet ails are numbers not the actaul description, so I need to store the number but display the description for the manufacturers and manufaturersdet ail

Please I need help on this problem desparatly

Thanks soooo much in advanc

Hi Kevin,

The datagrid itselfs holds no data, so you have to look to the underlaying
datasource.

That is mostly a datatable as part of a dataset.

When you use a currencymanager to keep track of the current active row in
the datagrid, and also look at datbinding from the textboxes and to the
dataview and its rowfilter, I think you are halfway to your solution,

I hope this helps?

But is there no way I can do all this in the datagrid itself? I would really like to stp away from the textboxes and try to doo all the stuff in the datagris, like adding, updating and deleting records. But my biggest problem is creating a combobox field and filtering one combobox filed based on another combobox's selection. I need to know how to do this, if there is now way I suppose I'll have to settle for the textboxe idea... :(

Hi Kevin,

A lot of approaches, one approach is to make a simple select of manufacurers
and let that dataset be the source for the datasource from a combobox.

With that datasource you choose the manufacturer and do a new select from
the contacts that builds a new dataset of the contacts that is the
datasource of your grid.

Than one button to save the dataset, one button to delete a row from the
dataset, and one button to reset the dataset from it status at the select.

Try to make a simple solution as this first, it is that difficult and you
have your sample.

Hi Co

Sorry for the late repl

When I was talking about the combobox, i meant a combobox inside a datagrid, not the native combobox that you put onto a form. I want to know how to make a cell in my datagrid a combobox,and upon the selection of that combo box filter the possible values of another combobox in another datagrid cell- is this even possible

Thanks for your help so far
