VB GridView control will not allow code in the vb code file to access a data column that has its visible property set to false. When it is set to true, the data column can be accessed with no problem. Any suggestions as to how to correct this? I have looked through the documentation, text books, and I have not found anything that gave me any clue as to what the problem could be. I thought that the property was just applied to the column, not that it would remove the column from being accessible.

View 6 Repliesi have a DataGridView responsible for showing a bit of data and two of my columns allow for user input using comboboxes.The trouble is that one column only needs to show preset values in it's list, but the other needs to both show the presets and allow for the user to enter in their own values.i accomplish this by showing the editing control for the combobox with this bit of code:
Private Sub DGV_EditingControlShowing(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewEditingControlShowingEventArgs) Handles DGV.EditingControlShowing

I am having trouble in allowing the user to select the row in the datagridview.
I managed to include the checkbox column in the datagridview but i do not know how to wrte the code such that when the user wants to update or edit the data in the checked row, he just have to check the affected rows checkbox, can be one or many, and then click on ok button, which will then lead him to the data updater form, allowing him to update the data.
Currently i have the below code which can populate the checkboxclumn only.
dbProvider = "PROVIDER=MICROSOFT.Jet.OLEDB.4.0;"
dbSource = "Data Source = '" & Form1.TextBox8.Text & "'"
con.ConnectionString = dbProvider & dbSource

I am trying to put an unbound button in the last column in a DataGridView control and it appears way, way off to the right when I run the app. I have to scroll all the way to the right to get to the buttons and then manually resize them to show up the way I want them to. I am using the Edit Columns feature found in the Smart Tag of the control. It works ok when I place them anywhere else in the columns! It only messes up when I try to place them at the end of the columns.

View 4 RepliesI would love some help on how to get a DataGridView's Row & Column location on a mouse double click. My program requires that I dynamically add n-number of tabpages with DGV's so I declare my own class that inherits TabPages and creates its own DGV control.
For the code below I use a simple form (form1), add a tabcontrol via the forms designer (tabcontrol1) to it and remove the two default tabpages keeping the basic tabcontrol.

View 1 RepliesI am developing a software using microsoft visual studio basic 2010. I used a datagridview control to display a list of data from product table. What I want to do (actually I am not sure how to do it, or is there a way to do it), when I choose one of the value in one of the column inside the table, I want it to open a form that contain data(details) based on that value.
How to do it? How to call the value that I pressed, so it can be used to open a new form containing the details of that value
Example of the data: (the "system" column) SYSTEM
topaz
nex1300
Nec
If I pressed "topaz" system, it will prompt me to a new form containing the details of that "topaz" system.
I insert DataGridViewComboBoxColumn columns in a DataViewGrid. That works fine.
Now, I want the user to be able to not only select one list item, but to "drilldown" into the list that is behind the combobox, allowing him to edit (insert/delete/update) the list.
I think it would be a good idea to display a ".." button right behind the dropdown button of the combobox. Pushing it leads to a dialog where the list can be maintained.
What I am stumbling upon is:
How would I create such a custom combobox? Is ComboBox (which is the base for the combo box that the combo box column creates as its edit control) open enough to accommodate such an additional button? What would be the container of the tiny buttoon -- the ComboBox descendant? How I would make the grid create and handle such a custom combobox?
I currently try to solve this by subclassing DataGridViewComboBoxColum, using a DataGridViewComboBoxCell descendent in its CellTemplate assignment, and overriding PositionWEditingPanel and PositionEditingControl to manipulate the sizes of the panel and the combobox so I'd have space for the tiny button. Is that the correct way?
Or would I have to create a DataGridViewColumn descendant which creates a Panel containing a DataGridView combobox edit control and the tiny button? How would I make sure the column keeps care of the combo box so it has the correct items etc?
Once I read the property for DataGridView Column which allows Grid Column to adjust as per the data width. I can not recall it or find it.

I'm using Visual Studio 2005 on Windows XP.When I drop a new DataGridView into my Windows Forms, and try to make 1 of the columns a checkBox, VS2005 gives me TWO of each columnType choice:
TextBox
TextBox
CheckBox
CheckBox
[code]....
Is that normal? Should I use "CheckBox type 1" or "type 2"?Also,When I make 1 of my columns a "checkBox", and then try to use it, the checkBox seems keep turning itself back ON.I turn it ON, and then click on a different column or row, and the checkbox stays ON, like it should.But if I turn the checkBox OFF, and then click on a different column or row, the checkbox magically turns itself back ON. I can't find anything in my code that says "turn it back on". And I've never connected it directly to any data source.
