Gud Morning All,
i have checkbox column in my datagridview,
when user checks the checkbox i wnt to fill other columns by some constant number.
where shuld i write the code & how to check whether checkbox is checked or not?
in our usual checkbox we can do it by->
checkbox1.checked=True
but for a checkbox as column in datagridview , there is no "checked" property.
so Will anyone please tell me how to do it?

You can still hook up an event. Is this ASP.NET or winforms ?

OK, then it's a lot easier. You should be able to attach click events to your columns, just by adding a click event in the column definition.

In that case, you should forget about datagrids, and work through a beginner book on VB.NET, just the language, not any forms stuff.

I've used VB.NET 2003 Standard to create a form using the wizard.
On the form, I had a bound textbox - txtUnitOfMeasurement.
This was bound to an MS Access table, tblSuppliersProducts, and a numeric field called UnitOfMeasurement.
This worked fine.
I then upgraded to VB.NET 2005 Express, and swapped my textbox for a combo box, and added the following settings to the combo:
Data Bindings - SelectedValue = tblSupplierProductsBindingSource.UnitOfMeasurement
Data Source = tblUnitOfMeasurementBindingSource
Display Member = UnitOfMeasurement
Value Member = MeasurementID
This too is fine, on my experimental dummy first record - it saves my changes to the UnitOfMeasurement field in tblSuppliersProducts - proving, to me, that it is bound correctly. However, when I press 'Add', it retains my previous combo box choice (which isn't a huge problem) on the new record, but when I fill in the remaining fields, and press Save, I get an error message saying that tblSuppliersProducts.UnitOfMeasurement is null.
I am obviously not doing something properly in between changing my text box for a combo box, but I don't know what.
Can you help?

Is your combo box perhaps binding again, and reseting the data source ?

Thanks for your reply. I'll have to have a look.
Unfortunately, as I'm developing the app from home, I don't have access to it in my "real" job!
Another problem is the seemingly unnecessary lines of code that the form wizard throws in. I'm pretty new to all this, which makes it that bit harder for me to read what its done.
Oh well - a bit of debugging to do tonight, then!

The menu has nothing to do with it. You need to add menu items which call code to do these things.
The OpenFileDialog class is what you need to do a lot of this ( i.e. it's where you will start )

You mean open a database ? Set the MDB to be your data source in your data layer. I assume it's format is predefined, or will you just look through it dynamically ?

You're diving in a little too deep. However if you want to persist with this path, you should google on how to connect Access to VB.NET, you'll find more in depth answers than I can give here.

I'm not sure if ADO.NET does that, I've seen people using ADOX for this purpose.

Hi All,
Is there anyway in which you can pause a timer function?
for example when a certain button (say pause) is pressed, the timer1 is paused, and then when a button (say restart) is pressed timer1 continues from when it was paused.
Thanks in advance, you lot have been a great help!

I don't believe so, there are only stop and start methods.

Same as the last time I answered this. Your dataset doesn't contain any tables. Have you looked at where the dataset is created, and checked that any data is being returned ?
