I have a bound datagridview which populates from the database using parameters. I've added a combobox column through the datagridview properties. How do I access this combobox column datasource?
View 9 RepliesI have setup a datagridview with one column as a combobox and bound to a dataset.
However, during runtime I want to refresh that column to show the changes. How do I do that?
I'm trying to setup a form to search for data within an existing DataTable.
FilterColumnsComboBox.DataSource = WOTable.Columns?

I could hard-code in the column names ("WO_Number",WO_CustID","CustLastName", etc...), but would prefer to pick this up dynamically (partly because I want to reuse this code later).
public Enum ClaimStatus
Ongoing = 0
Completed = 1
[Code]....
With code above, how do I assign the value to the combobox while retrieving data from the table so that it point to the corresponding combobox item. For example, if the value of status_ID is 1 then the combobox should show "completed" in the datagridview.
I'm working on VB .NET 2008.
Target: Bind dynamic datasource in a cell of a Windows.Forms.DataGridView depending on the selection in previous column. The grid must have 7 columns. If the selection on comboboxcolumn 2 or 4 is done, the datasource of comboboxcolumns 3 and 5 mus change using a query with previous selection as parameter.
In a first try to develop this functionality i've tried to use Telerik.WinControls.UI.RadGridView control. I've created a customized celltemplate with a combobox in order to have different datasource for each cell on the same column. All worked fine but seems to be some kind of bug in RadGridView, because when the combobox is presenting the list, after selection the list continued showing, doesn't dissapears as expected.
Ok, after several days of fight with RadGridView, I give up, and I tried to use same strategy but using Windows.Forms.DataGridView. I've created two classes one inherited from DataGridViewComboboxCell and other from ComboBoxColumn, in order to insert my own combbox or have the chance to have access directly to the combobox values. But the combobox showed is the default combobox not my own combobox.
how can I create a custom comboboxcell but using my own combo, and having access from outside to this combo?
Let's say that I have a DataGridView(myDGV) which I populate as follows:
'...
Dim strSQL as String = "SELECT col1,col2,col3 FROM myTable"
'....
myda.Fill(myDtb)
myDGV.DataSource = myDtb.
'The above code fills the DGV with data from the underlying query
'of the DataTable.
'Supposing that I want to add an unbound Column to the end of the DGV which appears together with the data returned by the query, is it possibe?
I had a DataGridView that was bound to a Table in my typed DataSet. I recentyl added a new column to the table in the database and updated the table in the DataSet accordingly.Now, when I go to the DataGridView to update it, the new column does not appear under the "Databound column" list. I tried setting the data source to "None", then reselecting it. Still, it does not show the new column. I then deleted the DataGridView and re-added it to the form. Again, same result. However, when I select the data source, then click "Preview Data", it show the added column.

The problem I now face is that the 'index' value of the combobox item for each row is in the field specFieldType which is populated into the datagrid.I need to be able to set the value of the ComboBox for each row when the form is opened, and also be able to save the index value of each row selection if any changes are made/saved.

I have a DataGridView control with two columns:
colName
colAnnounceURL
I also have a ComboBox that I need to bind to the colAnnounceURL in the DataGridView. So everytime I add new rows to the DataGridView, the ComboBox will be updated with the items in colAnnounceURL.
I have tried the following to no avail:
cboAnnounceURL.DataSource = dgvTrackers
cboAnnounceURL.DisplayMember = "colName"
cboAnnounceURL.ValueMember = "colAnnounceURL"
The code does not cause a crash but does nothing.
Both controls are visible to the user. The idea is to have DataGridView act as AnnounceURLs manager and ComboBox to set the active AnnounceURL.

View 1 RepliesI have an unbound DataGridView control that displays a few columns of account data. The first column is a combobox that I fill with data from a dataset of names filtered by what's in a customer field on the form. When you click on a combo on one of the populated rows, the available names come up in the combo. But if the first click in the datagridview is on a new row's combo, various (incorrect) names appear. Only after you click on one of the populated row's comboboxes, does the correct data appear in the new row's combobox control.
I don't really understand why this is happening. I have been using the EditingControlShowing event to populate and add the combo to the new row, but it doesn't seem to be working very well. I hope someone out there has some ideas about the correct way to do this.
