I have 2 datagridviews on different tabs of a tabcontrol.The user can input names into datagridview1 column1.I want these names to automatically appear in datagridview2 column1, in such a way that when rows in datagridview1 are added and removed the same rows are added and removed in datagridview2.I also want the column sort function to effect datagridview2.

I even have it set up so I can filter through the DataGridView by sorting though a specific company in the database. However, now I want to link specific cells from the DataGridView to other VB features such as a text box and check box. I am a bit lost as to the coding. In the DataGridView, there are numerous columns that contain a check box and I need them to correlate to actual check boxes I have in the form. I can do it through binding the check box on the form to the data source and it works but if I run a filter or sort through the company, the check boxes from the DataGridView no longer carry over to the actual check box on the page.

View 3 RepliesI'm using the follow code to grab values when a row is selected on my datagridview:
Me.DataGridView1.CurrentRow.Cells(0).Value
in this case for the first column. I am doing this for several columns. What I would like to do is switch to specifying the columns by name so the code won't have to be changed if columns are moved around. I have tried several things that didn't work. Can anyone supply me with the code to retrieve the value of a column on a selected row by the name of the column?

View 3 RepliesI have a datagridview for the transactions table. On the datagridview there is a combobox column for the type id field in the transactions table. This combobox displays the transaction type name from the transaction types table and puts the transaction type id into the transactions table. That much is okay. But each transaction type belongs to one of several categories. I have a categories table. The category id field in the transaction type record points to the id of the categories table. The category id is not in the transactions table, it is in the transactions types table. I need to know how to link the categories combo box on the datagridview to the category id in the transactions types combobox, which isn't even there right now. At present the transaction types combobox does not display the category id. It displays the transactions type name. Do I need to add another combobox to link the categories combo to the types combo?
I need to have it first and foremost so it will display the correct category when existing records are pulled up. I think I could do this with a join to the transactions type table in the categories combobox. But that wouldn't cause the transaction type combo to filter by category when a new entry is made.
Can someone advise as to the correct way to link comboboxes in this type of heirarchy?

I have a simple DataGridView that I fill in with data from a SQL server source. The query is fairly simple and after the grid gets populated I manually add several new columns and then iterate through each row and fill in the columns with appropriate data. all that works well. but now when i click on a column header to arrange the data the data in the columns that were manually added disappears. is that suppose

View 2 RepliesI am workinng on an aopplication using the DataGridView.My intent is that the DataGridView is displayed with four columns, the user clicks on a row in any column and the complete record for the selected item is displayed and the DataGridViewis no longer in view.
The code to do this is in the event "dgvCollections_CellContentClick" and the function works exactly as I want it to.The problem is that when I want to sort by a specific column I click on the column header and not only does it sort , it calls the 'CellContentClick' event and the details form is displayed, which I do not want to happen.Is there a way around this problem other then using the "dgvCollections_CellContentDoubleClick" event to select the detail? This was what I did as I sterted this project and I found that the double click was very sensitive and often did not work. The single click is much better for the eventual user.

View 18 RepliesI�m migrating a project from VB6 to VB.NET 2010 Express. Im replacing msflex grid with datagridview. But i�m not quite familiar with it. Im not using datasource. This will be done (far) latter.
So far i�m filling datagridview by code reading a recordset from mdb. Works fine.
The problem is that, I have defined the columns at visual studio designer mode, without using any code. When I open my mdi child form for the first time it works. But If I close this form and open it again a error occurs because it loses the defined columns.
how to preserve columns defined at design after close de form?
My MS-Access database contains 30 "table" files with identical formats (e.g. Composer, Arranger,Lyricist, etc.) and I use a common VB.NET form and DataGridView for displaying and editing any one of the 30 tables. When a user makes a menu choice, the menu program puts the file name and its first field into two global variables and then shows a form that contains an unbound DataGridView. This other form then loads a dataset from the appropriate database table and programatically binds the DataGridView to the DataSet. (I clear the dataset before filling it.)
All goes well and three DataGridView columns are displayed for the first time. However on subsequent operations, the DataGridView retains the columns that were previously generated along with their column headings (but no data) and I get six DataGridView columns. On the third operation I get nine DataGridView columns.
I have unsuccessfully tried to obtain a count of the number of DataGridView columns so that I can remove them from the DataGridView but it always gives me a column count of zero.How can I accomplish the simple task of removing all columns from the DataGridView?

View 3 RepliesI have a datagridview and I have set the highlight property to full row, I also have a link column in my grid. my problem is, when I click on a row it get highlighted blue, but the link color is also blue so it becomes very hard to read. is there a way other than manually setting the cell forecolor to handle this issue?
View 7 RepliesHow do I put a large amount of data (we are talking of a datatable with probably 50 columns and maybe 500 rows) from the access database that is bound to a datagridview in my program into textboxes depending on the row of the datagridview row I am clicking on.
What I have in the access database is countries and companies that are attached to several different dates to each company. these dates are supposed to be filled into the textboxes automatically when I click on the company row in the datagridview and also when i fill in a date in the textboxes it is to be written to the access database when I save the update.

I have a program where i let the user dynamically add DataGridViews to the interface, those are also added to a list for easy management. All of the DataGridViews have their own datasources. I am using a Databinding source to get different DataGridViewTextBoxColumns to add.
The problem is the following: When the user adds the first table the following code runs:
dataGridList(dataGridList.Count -1).Clear()
dataGridList(dataGridList.Count -1).Add(NameDataGridViewTextBoxColumn)
No problem there and the right data is displayed, but when the user adds the second table i get an exception thrown:
"Provided column already belongs to the datagrid view"
I think this is strange since i access different DataGridView's right?
The point of all of this is to be able to view different columns in all the DataGridViews depending on the users choices.
Is there a way to add columns in a datatable to the intellisense of the datatable? Is there a way to display the columns of a datatable in a datagridview?
