Jul 11, 2010I get the DataGridViewComboBoxColumn cell value is not valid only when the record in the ComboBox table does not exist. I have done quite a bit of searching on this and I can't find this particular situation mentioned.
I have a datagridview with a comboboxcolumn on it, both generated entirely in oledbdataadapter code. The datagridview is created, then the combobox is created, then the combobox is added to the datagridview, then the datasource of the datagridview is set. It works just fine. Except if there is no matching record in the combobox table I get the "DataGridViewComboBoxColumn cell value is not valid" error popup. I could trap the error but it seems to me a beter way would be to prevent it from happening. Is there some property I can set or something I could do to compensate for the situation where there is no match in the combobox?
DataGridViewComboBoxColumn Change Event For Dgv?
Oct 13, 2011I have a dgv with several DataGridViewComboBoxColumns and when the user selects an item from one of these (product dropdown), i need it to repopulate another combobox (color dropdown) in the dgv for that same row - based on the value i get from the product dropdown. I've tried using the EditingControlShowing event; however, it only fires when I first select the dropdown .....?
Is this the right event I should be using? My other issue is that I don't know how to have the color dropdown re-populate for just the column and row I've selected. Here's my code so far for this event:

Add Items In The DatagridViewComboboxColumn Of DatagridView During Runtime
Oct 11, 2011My application is in VS2008 and coded in VB.net.
I have a datagridView(DGV) on one of my form.DGV contains a column of type DatagridViewComboboxColumn.I have another column of SrNo.
Consider Table1 to be the table from where my DatagridView is filled which contains following fields SrNo,Value1,Value2.
My requirement is i want to fill the values in my DatagridViewComboboxColumn from Table1.The DatagridViewComboboxColumn's combobox should contain values of columns Value1,Value2 of Table1.
Sample data of Table1
SrNo Value1 Value2
1 2 3
2 4 5
As data in datagridView is filled from Table1 the data of SrNo column of Table1 is also populated in one of the column of DGV.
Now my DatagridViewComboboxColumn combobox should contain the values of Value1 and Value2 of Respective SrNo.
Like Row one of my DGV has SrNo 1 as first value,so the Value1 and Value2 of SrNo 1 should be added to the row's DatagridViewComboboxColumn.
Select distinct Value1,Value2 From Table1 where SrNo=DGV.items(0,DGV.currentcell.rowIndex).value.H ope this Query willl make things more clear
