Sorry, I though the problem was resolved but unfortunately is not..I added this code to my form; Me.DgvReturns.Item(6, 0).Value = Me.DgvReturns.Item(5, 0).ValueThis Only affects the first line of the datagridview.. The second, third, fourth etc etc records are not reflected. Therefore, the vale of the textbox is not shown on the combobox.

I have a form with a DGV bound to a SQL database. the DB has three colums: ItemCode, ItemName, Status. The Itemcode field is a combobox complex binded (if this matters), the ItemName colum is a textbox. How can I have the ItemName colum auto insert the text for the ItemName colum when I select the associated ItemCode with the combo box. I'm pretty sure I need to use the "CellValueChanged" event. I'm thinking an IF Then statement with 'e' parameter and colum and row indexes just not sure how to address it.
View 5 RepliesI have a datagridview called DgvReturns, in this datagridview I have 2 columns - one is a textbox and the other is a combobox. The textbox is populated from a dataset while the combobox is built with 3 items Full Pay, Part Pay, No Pay.Now, what I want to do is for e.g., Full Pay to be displayed on the combobox column simultaneously.Therefore, for example record A has Full Pay the combo box should show show Full Pay, and if Part Pay it should show Part Pay from the drop down list.
View 6 RepliesI have a form and i have used a combobox along with datagridview and textbox.I have various values in combobox namely Mechanical, Electrical, Etectronics etc.When I select the option Mechanics, I wish only few fields of the table be updated in the gridview, with the type mechanics. The I am getting all the fields, instead of the specified ones in the query, in the grid view.Also, the where clause, is not being executed ie. It gives the entire database as it is.The database in the gridview does not get updated. It keeps giving me the old databse, even after updation, unless I Bind it again, with the data source.I am completely new to the concept of Datagridview and combobox as making the project for first time in vb.net.

I have a DataGridView with several columns. One column is a TextBox column named "Status". This column can only show one of three values: 'Final', 'Ready', or 'No Reportable'. I want to have some code that would turn the TextBox cell into a ComboBox cell when the user left-clicks on the cell to allow the user to choose one of these three options. When the user clicks elsewhere or the cell loses focus I want the cell to change back to a TextBox cell.
Here is what I have so far, but the code throws an exception indicated below Plus, I don't think the code would remove the combobox when the cell loses focus.
Exception: "Provided cell does not belong to this DataGridView control."
Private Sub dgvCalculatedResults_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgvCalculatedResults.MouseDown
Dim ht As DataGridView.HitTestInfo = Me.dgvCalculatedResults.HitTest(e.X, e.Y)

I have a tab control application, each tab loads a particular user control and each of those user controls will then add other user controls that are used amongst other the user controls. For example, I have an "ucQuotes" page and an "ucInventory" page, when the specific tab is selected, the "uc****" user control is loaded on that page, and in the case of "ucQuotes" and "ucInventory" they both use a control called "ucPartNumber"; a user control consisting of a combobox, textbox, and button. I have no issues reusing the shared user controls, in this case. My problem arises with my "ucQuickPrice" control, as it is always present at the bottom of the tab control form (separate from the tabcontrol, but on the same form), and it too uses ucPartnumber.
Here's my issue, as I type into the ucPartnumber combobox, the text I type does not appear in the combobox, it appears in the textbox of the ucPartnumber control that is being used on the tabcontrol page. There are no shared instances of ucPartNumber, nor do I have this issue between typing on one tab page and the text showing on the user control of another tab page.I tried just creating the ucPartNumber controls on the ucQuickPrice control, not adding a new instance of ucPartnumber on the .Load event, and the issue persists.
The combobox(s) in question are bound programmatically with about 40,000 items, ".datasource = dataset.tablename" not to a bindingsource. Autocomplete is set to none, I added code to utilize tool tips and the basic combobox filtering functionality. Is this a bug, or is there something I'm neglecting? I'm about 95% complete with this application, and this just happened today. I made the decision, to just reuse the ucPartNumber control on the ucQuickPrice control (originallly it's size and orientation would not fit, but I added some coding to detect what parent is adding ucPartNumber and to change its appearance accordingly). Before, I made this change, I did not have this problem. And, in trying to go back to how I had things set up before the change, the problem will not go away. if the whole control within a control verbage I used is a bit confusing, let me know and I'll try to better explain what is happening. At this point, I'm going to close and reopen vbexpress, as when I started this ordeal, vb started acting weird and wanted me to save all my work, it usually does this before locking up.

View 5 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?
