Populating DataGridView ComboBox Column During Runtime?
Nov 16, 2009
I've got a window with multiple datagridviews. Each with data from a separate dataTable. All of which are part of the same DataSet. There are a couple of places where one DataTable has a field joined with the lookup dataTable from the dataset. For example a lookup table for LugSizes has a field called LugSize that is also it's primary key. Another table called Device Terminations has a field called LugSize to which the user can only select those values from the LugSize lookup table. I thought it would be as simple as using the Items.Add method for the combobox column whenever a new lookup table row was added to its own datagridview. Unfortunately, when I try to initially clear the items list, the data error event is triggered for every row.
Here's a sample of my code if it helps:
HTML
Private Sub FillLugSizeComboBox()
Try
If colDTLugSize.Items.Count > 0 Then colDTLugSize.Items.Clear()
[Code]....

I 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.

I have a form with a DataGridView and ComboBox, both of which are populated with data from an Excel spreadsheet, the source is unbound. My problem is in repopulating the DataGridView with data from another worksheet in the same Excel file when the user selects the corresponding value from the ComboBox. For example if they were to select January from the ComboBox then the DataGridView would load in and display the data contained on say Sheet2, selecting February would load Sheet 3 and so on. I am running Visual Studio 2008.

I have a readonly datagridview that is bound to a datasource. It has two columns. Now I want the first column to have no cell borderstyle; and the second one to have 'All' (i.e. all sides of the cell shall have a border) as cell borderstyle. Before binding the datagridview to the datasource, I'm writing something like mentioned below but it's taking no effect. Assume the column in question is named DisplayName.
Code:
Dim newStyle As New DataGridViewAdvancedBorderStyle()
With newStyle.Top = DataGridViewAdvancedCellBorderStyle.Single
.Left = DataGridViewAdvancedCellBorderStyle.Single
.Bottom = DataGridViewAdvancedCellBorderStyle.Single
.Right = DataGridViewAdvancedCellBorderStyle.SingleEnd With
DisplayName.CellTemplate.AdjustCellBorderStyle(newStyle, newStyle, True, True, True, True)

I have a datagridview containing 1st column (combobox), 2nd and 3rd column is textbox. The combobox was filled-up using datatable. My problem is on loading form, I will get a records from my database and set the value of my combobox base on those records. So if I have 5 records from my database then I should have 5 rows containing combobox in my datagridview.
I tried the code below but there's an error saying "the following exception occured in the datagridview...." but it will display correctly, but if I click in any cell that error always appear.

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.
