Read Combobox Selected Value From Datagridview Instead Of Bound Value?
Oct 1, 2011
I'm loopiing through a datagridview and I want to get the selected value in a combobox, not the bound column's value. (I'm putting the contents of the dgv on a Word document.)
For icounter = 0 To Me.ConversationTblDataGridView.RowCount - 1
range.Text = range.Text & Me.ConversationTblDataGridView.Rows(icounter).Cells("PersonID").Value <-- I want to change "Value" so I get the displayed value, not the person's id
range.Text = range.Text & CHR(13)
Next icounter
It will not take .DisplayMember or .SelectedItem and .Selected returns True of False. Can anyone tell me how to get the name that shows in the combo box instead of the id number?

In the form below you see how the initial selected item is the first record of the table.. these controls are bound.. I want to initially show "Select one" in the combo box or nothing at all and the other controls not to be bound until an actual item is selected in the combobox..

With a DataGridView bound to a bindingsource, which is filled by da.fill(ds) . How do I go about deleting selected rows when the UserDeletingRow event is fired? I've used the following code in the event:
Dim dsEmplTran As New DataSet
daEmplTran.Fill(dsEmplTran)
dsEmplTran.Tables(0).Rows(dgvEmplTran.SelectedRows(0).Index).Delete()
Dim cb As New SqlCommandBuilder(daEmplTran)

For example; I have a DataGridView bound to a MYSQL Database. There are two string columns "Name" and "Gender". I need to make the "Gender" column a ComboBox where they can select "Male" or "Female".

Has anyone here tried putting a combobox to a bound datagridview? The selected value of the combobox will depend on the value of the corresponding column in the database.
I have a datagridview. When the user clicks the edit button, the application fetches the records from the database and binds it to the datagriview. But I want to show the Gender Column as combobox with selectable 'Male' and 'Female' values.
How could I add a combobox to bound datagridview?

I am creating a DataSet:
objSQLCEConnection.Open()
objSQLCEDataAdapter.Fill(objSQLCEDataSet, sSQLCETableName)
Then populating a DataGridView with the data:
DataGridView1.DataSource = objSQLCEDataSet.Tables(sSQLCETableName).DefaultView
I have a string field, EventAction, that is in the database.I want that column to be a combobox column.I want to add the different EventActions to the list and let the user select the action they desire.

I have a combox box on my login form which contains 1 and 2, I use it as so called accesslevel. Now, my problem is that only the selected item will get read. If I type 1 or 2, it won't get read. How do I make it possible for both selected and written ones to be read?

I can't seem to set the selected index or selected value of a DataGridView combobox when loading data from a database. My DGV has two combobox columns which are bound to datatables. The DGV itself is not bound initially. After adding a row, I select a value from each combobox which then populates the rest of the cells in the row. I'm using the EditingControlShowing event to add an eventhandler to catch the SelectedIndexChange of the combo boxes. This all works as needed. My issue comes when populating the DGV with saved data, I need to add the rows and set the selected index and/or selected value of each combo box. I've searched through various forums and articles for the last week with no luck.
I'm using VS2008 sp1, .NET 3.5 sp1 and SQL 2005 sp2 Express.

I am using vb.net 2010 and winforms and DataGridView. The DataGridView has a DataGridViewComboBox column. When I show the form with the DGV it shows this and empty grid but the column that contains the ComboBox shows the first item on the dropdown list. How can I have the ComboBox display nothing until it is clicked on and selected?

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code
,
Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

I have to maintain an ASP.net application in VB.Net.There is a page with a FormView bound to a ObjectDataSource.I have to add some business logic on the ItemUpdating event of this FormView.Unfortunately, some the data that I need to add this business logic is not exposed on the FormView user-interface itself, so I can not use FindControl to get the values (I could add the controls, bind them to the fields I need and set their visible property to true, but that's ugly).

Im having a problem getting the selected values of a listbox that is data-bound..
vb.net
Do Until CType(Ctrl, ListBox).SelectedIndices.Count = 0
For Each Index In CType(Ctrl, ListBox).SelectedIndices
[code]....
The error message says... "Operator '&' is not defined for type 'DataRowView' and string " "." And the only way I can get it to work is to pull out the & operator and change that line of code to this.
vb.net
'FROM THIS:
TableData.Miscellaneous += CType(Ctrl, ListBox).SelectedValue & " " 'Errors HERE
[code]....
The SelectedItem text shows up in the controls current state while debugging, correctly.. but after I finish the execution it shows up as "System.Data.DataRowView"?

There is something strange going on with my datagridview.
I've a data adapter that fills the underlying data table from a database. Then I assign this datatable as datasource to the datagridview Then I add a row to the datagridview and immediately I need to update the table in my database (as soon as user leaves the newly created row).
At this moment I have more rows (+2, not +1) in my datagridview than in the underlying datatable (the new row doesn't exists yet in it so the data adapter .Update method doesn't write anything to the database).
When DataGridView's .RowLeave event fires the undelying datatable is not yet updated. I've a question - is this behavior normal?

I bind a datatable to the combobox.DataSource on load. I then give the combobox aisplayMember and a ValueMember (2 different columns out of the datatable). In the SelectedIndexChanged of the combobox I would like to use the SelectedValue property of the combobox, just to test I MsgBox(combobox.SelectedValue) and I get "Argument 'Prompt' cannot be converted to type 'String'." Why isn't it displaying the value?

Appropriate Title would be: Bind comboBox Tag to database.I have a comboBox on form which is bounded but and I need to populate it manually. With some reading on net i have found a way but it is not working
I can populate my combo, select item in combo, update database but the problem is when I load my form it displays empty combo (combo is fulled with my custom data but nothing is selected it must select correct ItemText) and after selecting a value in combo, the value disappears as soon as combo losses focus .

I have a combobox that is bound to a database.After I click "New Record" to insert a new record, I want to default to the first item in the Combobox list. This will speed up user input.any ideas. I have tried most ways but this should work correct:
cmbAssetLocation.text = cmbAssetLocation.Items.Item(1)
But nothing throws an error.
