Datagridview Combo Box Behavior?
Jun 27, 2011
I have an unbound datagridview control whose first column is a combo box This contains a list of part numbers.I am having some problems with the datagridview automtically adding a new row when the combo box item is selected.If I select an entry from the data by typing in part number in full in the first row and pressing tab or enter then I get a new row created. No problems.However, if I then START typing a part number in the second row AND click on the part number in the list that is suggested then I DO NOT get a new row.However, if, on the first row I START typing a part number AND click on the part number in the list that is suggested I DO get a new row.
My code is as follows:
Private Sub dgOrders_EditingControlShowing(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles dgOrders.EditingControlShowing
Try

I have a simple datagridview that I fill from a mysql database using the latest mysql connector.net.I configured my columns in the datagridview collection and the data displays fine.I don't want the user to edit data directly in the grid so my datagridview is not readonly but all my columns are except the checkbox one. If I set the datagridview readonly I can't check my checkboxes.I added a checkbox column to be able to delete multiple rows easily but I can't uncheck a checkbox.
Let's say I have 3 rows in my datagridview I check line 1 checkbox- I check line 2 checkbox- I uncheck line 1 checkbox- I check line 3 checkbox As soon as I check line 3 checkbox, line 1 checkbox becomes checked "automagically"

is there a way to set a single cell as a combo box? it looks to me that you can only set the whole column.

I created a data grid view from the datasources list and converted 1 of the columns into a combo box. Unfortunately, the combo box isn't acting like a proper combo box. When I start typing, the combo box does not display the characters I have entered. All it does is begin looking for the entry that matches what I am typing.
This is no good for my purposes, the user needs to be able to see what they have typed. Is this how it works when in a grid? I have tried playing with a lot of the column options but nothing makes it work correctly.

I have a DataGridView on a form that is being populated from a SQL table dataset by giving criteria from a previous form. I have 6 columns in the dataset, of which the last column should be combo box column containing items "Done" and "Pending".
How do I make this bound column to a combo box column and display the value as well as the alternate item too in the combo box?

Below is the code to create a single Editable ComboBox column in a DataGridView on a form. I believe I have follwed the instructions to allow the user to input new values other than those in the list, however if you create a new project and add a button and a DataGridView control onto the form, then copy and paste this code and run the program, you will find that you cannot type any character in the edit box other then characters that exist in the list and only 1 character will be displayed at a time. I have set the Autocomplete value to 'False' and setting it to 'True' at least allows me to type more than 1 character but still not any strings that don't exist in the list.You can even remark out or not use the entire Call Validating sub routine to see the issue of not being able to type in the cell.

i am using a couple bound comboboxes in a bound datagridview. It seems though, when the combo's are changed, and the tableadapter is filled again, the changes are not being saved to the table. Is there a special trick to getting the data in the combo boxes to saved when the values are changed?

I'm trying to select a company name from a data bound combo box, then display the relevant record in a data bound datagridview.
I've currently used the Data Sources wizard to set the connection string, create the dataset and dragged the combo box and datagridview onto my form.[code]...

I am building a simple GUI to view data within a database. I am getting stuck when it comes to filtering data. I have followed Beth Massi's video entitled How Do I: Filter data on the client?
However my datagridview will not filter, it simply moves the highlighted cell down to the location of the item selected in the combo box. The items in the combo box are also repeated as opposed to grouped by what they they are called, for instance I have a column called region and every cell contains the text "West" and the combo box just shows a list of all the cells as opposed to just one.I followed the video several times and every time this happens. Even with a new project. Could it be because my data isnt a table but a query of several tables? I can filter on this data in excel and access easily.

I've inherited a form that has a DataGridView that is bound to a dataadapter and it is connected to a binding source. Within the DataGridView is a combo box that is bound to its own bindingsource which basically just calls a stored proc to bring back the possible values for the dropdown combo control
With a blank new row and sometimes even with an existing row, this value for the combo box can be NULL which is a legitimate value for it if no value selected. Problem is everything is so tightly bound if the user mistakinly clicks the dropdown then a value is populated and there's no way to get back to NULL
I've tried to catch the mousecelldown event and others to try to catch this before a value is selected but the Cancel=True doesn't work - I can catch the event but don't know how to return the cell to unclicked or reset it to NULL or pre selected value if NULL I know how to at a new row with the datatable and then set the combo datasource to it and I have my null blank value but with a tightly bound control how do I add this row?

I have a datagridview bound to a bindingsource. This datagridview contains one column which is a combo-box.
Upon a click on a button,I change the underlying datasource. The selected values of the combo-boxes change.
But the change doesn't appear on the screen ! To make the changes visible (refresh each combo-box), I have to hover on the datagridview with the mouse or use the scrollbar !
Question 1 : why do I see this ?
Question 2 : what should I do to make the changes immediately visible ?

Private Sub DataGridView1_CellBeginEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellCancelEventArgs) Handles dgvProduct.CellBeginEdit
ComboBox1.Visible = True
ComboBox1.Select()
ComboBox1.Focus()
ComboBox1.Text = DataGridView1.Item(0, DataGridView1.CurrentRow.Index).Value
End Sub I have a datagridview, all i want to happen is when i click on the cell (on columns(0)) the combo Box will appear (combo box is with item) so i will select the items on list.. after selecting the item it will display on the current datagridview cell. now my problem is when im Begin Edit, the focus should go to the Combo Box in order to select the item by Keyboard and not by mouse..

i wanted to link options selected from Comb box A (general) to specific options in combo box B (specific). I want to pick a word in Combo box A that has specific words/phrases in Combo Box B show. But not all the words to show in the combo box B if they aren't associated with the Word picked in Combo Box A. Ex.When "Soda" is picked in A, only "Coke, Sprite, Fanta" should be visible in combo box b, not everything else.This is the code i used to make the boxes, but i don't know how to link them.
Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' fills the combo boxes with values
