Im new with datagridview. . . .and i want to delete a certain row or the user will select a item in datagrid but im find it hard to do it
If dread.HasRows Then
Dim cmd1 As New MySqlCommand("DELETE FROM product WHERE p_code = '" & listgrid.SelectedRows(0).Selected & "'", conn1)
[code].....
I wanted to select the row the user was last working on in the datagridview. So I created a setting to contain the row index. But then I had trouble using the form load event to select that row in my datagridview. It would always select the first row. I then moved the code into the DataBindingComplete event and it worked like a charm Example:
Private Sub dgvTaskList_DataBindingComplete(sender As Object, e As System.Windows.Forms.DataGridViewBindingCompleteEventArgs) Handles dgvTaskList.DataBindingComplete
[code]....
PS, if you want to select the full row, make sure the DataGridView Selection Mode property is set to FullRowSelect.
I am making a program which remembers my last selected row in a data table. I have done this by adding a column with a CheckBox, upon CellClick the CheckBox is checked, and upon ellLeave it is unchecked and the new cell is checked, after every action a Update command is run. There will never be more than one row with a checked cell in the DataGridView,however, the data table is in a relationship with other tables, so there may be more checked cells in the data table itself. My problem now is selecting the row with that cell when I open the program and when changing between other data tables and back again.All solutions I found on selecting a specific cell in a DataGridView are referring to index numbers, and in my case I need it to find a data value in a column, I do not know the specific row, only that one row contains the value of True while everything else is False.
View 4 RepliesI have two drop down. SelCurrentManuf and selCurrentModel. I want the option in selCurrentModel to change depending on the option selected in selCurrentManuf. How do i do it?
<asp:DropDownList runat="server" ID="selCurrentManuf"></asp:DropDownList>
<asp:DropDownList runat="server" ID="selCurrentModel"></asp:DropDownList>
This is how i am currently populating selCurrentModel
Public Sub PopulateCurrentModel()
Dim mySelectQuery As String = "SELECT * FROM Model where ManufID = "+ selCurrentManuf.Text+";"
Dim myConnection As New MySqlConnection(Session("localConn"))
[Code]...
but it only populates the first selected manuf, and doesnt change after
Private Sub selCurrentManuf_SelectedIndexChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles selCurrentManuf.SelectedIndexChanged
PopulateCurrentModel()
End Sub
I know some of you have been aware of my great frustration with the DataGridView control's rendering problem, and of my frenetic efforts to figure out a way around it. Well I stumbled upon the solution, posted by an obvious genius here: [URL] One of the responses to the post (which is in C code) showed how to do this using Visual Basic code.

View 3 RepliesAlright I have a DataGridView, where the user can click on the column headers to sort. When they add a new row while a sort is applied, the record isn't created until the moment they validate the row(which they cannot do till they exit the newRow). How can I make the row be selected once it is sorted?The DataGridView is databound.The selection mode for the grid is full row.I'm using VB.NET with SQLite database backend.I suspect I need to use the RowsAdded event, or DataBindingComplete events. The records in question do have a unique GUID attached but it is NOT visible in the DataGridView.
View 1 RepliesI am using VS2008 and I have a form which has a datagridview. This is for an invoice where I already have the user select the customer from a details view and want to have the items in the datagridview change based on what the customer selected. Then when the item is selected I want to have the price change accordingly.
So far I have the customer selction as well as the item combobox(not limited to cust items yet) appear, but I cannot figure out how to get the join of the 2 items (cust+item as the price varies from cust to cust) to change the price. Question is, is it possible to do this in the same datagridview, or should i try to just break this down some other way?

I'm using a search code using a textbox then it lists the record on a datagridview if search is successful. After the search, the user could select the record on the dgv in which later on can be edited or deleted. Edit and delete button is disabled when nothing is selected on the record. What I want to know is how to trigger an event to make those buttons to be enabled when a record is selected. By the way my datagridview is connected to my textboxes. My question goes something like this, but this is totally wrong.
dgvStud_CellClick = Nothing then
btnEdit.enabled = true
btnDelete.enabled = true
End If

View 5 RepliesIm having a little trouble setting focus on a row in a datagridview. When a user presses the Enter button in my datagrid, a sub is called and the window is closed. Now next time i display the window, the selected cell has moved one row down. This is because when you press enter in a datagridview it jumps to the next line (wich i really dont want it to do). Now then in my forms shown event i placed the code: Datagrid.rows(0).selected = True Now this highligts the first row when the window is displayed, but when you press the down key, it jumps to the third row, because even though the first row is highlighted, its the second row who has focus (because it jumped their after pressing the enter key) How can i set the focus on a specifik row in the datagridview in vb2005?

Is there a way to manually select a row? Right now, it uses the default selection method where when you left click it highlights the row, but I would like it so when your right click on a row it also selects the row, because I would like that row to be active when the row is right clicked, and not just left clicked.

I have a DataGridView table that I allow the user to enter data into. I have a button to add a row. This works OK but how can I select that row after the button has been clicked. The reason for this is so the user will not have to scroll to the bottom of the list the enter data into the new row.
