I have been scratching my head for a while over this. So I have added in design mode a datagridview to my form. The datagridview has 2 columns, one column is textbox column, the other column is combobox column. I have figured out how to programmatically populate the cells of a textbox, however I can't figure out which property to use to populate the combobox column. I am simply looking to have a dropdown with 3 options. Any ideas would be great. P.S: I just picked up VB.net 2 days ago so I apologize if the question is primitive:).

If you have a DataSource in your combobox, you can do this Dim dgvcc As New DataGridViewComboBoxCell With dgvcc.DataSource = answerStr.ValueMember = 'CampaignAnswerId'.DisplayMember = 'Answer' End With DataGridViewName.Item(columnIndex, rowIndex) = dgvcc or you can just do this Dim dgvcc As New DataGridViewComboBoxCell dgvcc.Items.Add('test1') dgvcc.Items.Add('test2') dgvcc.Items.Add('test3') DataGridViewName.Item(columnIndex, rowIndex) = dgvcc Take note that you have to do this while you loop inside the DataGridView. For rowIndex as integer = 0 To DataGridViewName.Rows.Count - 1 Dim dgvcc As New DataGridViewComboBoxCell dgvcc.Items.Add('test1') dgvcc.Items.Add('test2') dgvcc.Items.Add('test3') DataGridViewName.Item(yourtextboxcolumnIndex, rowIndex) = dgvcc Next.
Member 10192835 6-Oct-13 22:38 6-Oct-13 22:38 Dear sir, I have made a form in visual basic 2010 and i have used the sql database, In party master form i have added a button (Update), when user click on the update button, the another form update will open and there there is a datagrid where all the party master record will present.on upload form there is a buttopn named update, delete and cancel, when the user click on update then record will update in the grid view and as well as database too, same case for delete and cancel.

Following are the code Imports System.Data.SqlClient Imports System Imports System.Data Imports System.Data.OleDb Imports System.Windows.Forms.DataGridView Public Class frmupdate Inherits System.Windows.Forms.Form Dim cnn As New SqlConnection('Data Source=.
VB.NET DataGridView Tutorial The following lessons teaches you the fundamental programming concepts of DataGridView control and its supporting classes, in detail. The DataGridView control provides a customizable table for displaying data. I need the code for delete a selected row from datagridview in VB.NET. Could you give an example on how to perform a sarch in several gridview controls with input.

I Have downloaded the files you have provided. I am beginner so im practicing C# I Cannot run this application Error. MyXMLdata.xml is not exist in the zip file. Eror ' Connection Failed.
Provider=Microsoft.Jet.OLEDB.4.0;Data' Provider is not registered. When I delete execption messages from the source code, simply empty datagrid page. What to do to run this app? Is it because of the missing xml file? I have Done Provider=Microsoft.Jet.OLEDB.4.0;Data application read, write, update data form previously. It was my first.
My second question is for my work regarding the refreshing data from database; when I delete input from acces database. It is not refreshing the form page. Showing old record.
Actually it is deleteded from the database. When I add new input into the database, it is not refreshing not showing in form. But When I restart the program it is showing. Which is simple way to refresh data to show changes? Even if not work I can replicate similar form I gues. Again Thanks for valuable time and informatins.

Best Regards Serkan Ozkan. Mark Remington 22-Sep-10 6:07 22-Sep-10 6:07 I am trying to use your example as a test application to change the text color of a row which is bound to a data table but I am having difficulty. I create a table with the following code. DataTable aTable = new DataTable; aTable.Columns.Add('COL1', typeof(int)); aTable.Columns.Add('COL2', typeof(string)); DataRow dr; dr = aTable.NewRow; dr0 = 1; dr1 = 'Item 1'; aTable.Rows.Add(dr); dr = aTable.NewRow; dr0 = 2; dr1 = 'Item 2'; aTable.Rows.Add(dr); dr = aTable.NewRow; dr0 = 3; dr1 = 'Item 3'; aTable.Rows.Add(dr); dataGrid1.SetDataBinding(aTable, '); From here, I want to set the color of a particular row (as an example, let's say Row 1) to System.Drawing.Color.Red.
The DataTable has no correlation to color so it can't be set in the DataTable. Do you know how I can set the text color of a single row in the DataGrid? Mikabongio 29-Apr-10 4:24 29-Apr-10 4:24 Hi Huseyin, I have a question related to this topic. Suppose you need to bind a textbox to a datatable which has a 'Value' column. I'd write: textBox1.DataBindings.Add( ' Text', dt, ' Value'); Then, just to see it, connect the datatable to a datagridview via the following code: dg = new DataGridView; bs = new BindingSource; bs.DataSource = dt; dg.DataSource = bs; Now, if you edit and change the textbox content, 1) why the cell in the datagridview is not updated automatically? I need to click the datagridview.
2) why the dt.GetChanges returns null even thou I see the new value into datagridview control? My feeling is that datagridview control performs actions the textbox does not when data changes or you move around cells. Thanks a lot.
