I have a DataGridViewComboBoxColumn in my DataGridView. I want to programatically drop down the list box so that the items arte displayed. With a normal combo box this is done with ComboBox1.DroppedDown = True. The problem is that the DataGridViewComboBoxColumn doesn't have the attribute DroppedDown.

I am having trouble with a comboboxcolumn in a datagridview. I have a MySQL table with "products" which i have managed to populate the combobox with, but i would like it so when a user picks a product from the combo list, the rest of the fields in that row are populated with the product information, price etc.
View 4 RepliesMy application is in VS2008 coded in Vb.net I have a datagridView on one of my form.This is filled from the database at the load event of the form.The datagridView also has a column of type DatagridViewComboboxcolumn. This DatagridViewComboboxcolumn already has 4 values added to it in its collection during design time.My requirement is when the data is loaded in the datagridview, the corresponding record which is supposed to be loaded in DatagridViewComboboxcolumn should compare its value with the value of DatagridViewComboboxcolumn.And if the value matches than that value should get selected in DatagridViewComboboxcolumn. The database will have the any of the 4 values that are already in DatagridViewComboboxcolumn.It just has to compare both values and select the matching value. Below is my Code
query= "Select Record1,Record2,Record3 from TableName"
cmd = New SqlCommand(query, connection)
dr = cmd.ExecuteReader()

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

I have a standard DataGridView. One of the columns is a DataGridViewComboBoxColumn. When I select one of the ComboBox items, I want to trap the change and add additional columns based on the item selected in the ComboBox. I've tried using CellValueChanged for the DataGridView column, and a bunch of other events, but none of them is fired when the DataGridViewComboBox value is changed. What event can I trap to make this happen? Right now as I said, I am using CellValueChanged, but of course the event doesn't fire until I click on another cell...

I'm trying to manipulate the events of the dataGridViewComboboxColumn in order to execute an SQL statement based on the value change of the cell (IndexChanged) and update the database table. Either this or how can i update several rows in a table from a datagridview ? if you check my previous posts you'll understand the whole story behind this question and to which grid i'm refering to.
View 2 RepliesI am trying to create a basic quoting tool but got stuck on how to clear and change the item collection from within a combobox for a datagrid.What we have is a list of 4 columns like a. Device b.TypeofService c.State d.Price Inside a sql database. Data is also structure like above as well.
I have a datagridview where the user will populate a,b,c and the price will be display and a total at the end. However a,b, and c aren't related in my current application. The combobox will show all possible dinstinct values for each column.
This works fine but I want to refine the application to only show the values of b. which are in the database after the user select the value for a. I have tried searching on how to do this as I assume to the Contry/State/City situation but could not find anything for a datagridview control in VB.NET.
Can anyone point me in the right direction? If I cannot do this dynamically from within a datagridview I was thinking of maybe creating three combo box outside and having it populating the datagridview afterwards but it wouldn't be as nice.
I have a DataGridView that is bound to a DataSet I created from a database table named Contacts. The Contacts table contains a field called StatusId. StatusId is a foreign key to a table called Status. The Status table contains StatusId and StatusName.

I have a datagridviewcomboboxcolumn which has its .DataPropertyName set to a int field, its .DisplayMember set to a nvarchar field and its .ValueMember set to a int field on a lookup table. I have captured a dataerror which states that the control is trying to push the .DisplayMember(nvarchar) to the .DataPropertyName(int) field. When I load existing data it works fine. When I try to leave the datagridviewcomboboxcolumn after selecting a different value in it or leave it when I add a new row, I get the error. What am I doing wrong?
