[2008] Datagridview - Filter The Grid Based On A Product Name
Feb 4, 2009I have a datagridview that's taking a while to load because my table contains almost 5000 records. How can I provide an easy way for clients to filter the grid based on a product name. I was thinking of having labels with each alphabet on my form and when they click a label it filters the bindingsource according to the chosen alphabet. this seems like an awkward solution though.

View 2 RepliesDataGridView Is Displayed With Four Columns?
Jul 18, 2010I 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 RepliesPreserve Columns At DataGridView?
Sep 1, 2011I�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?
RE DataGridView - Remove All Columns In .NET?
Mar 26, 2010My 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 RepliesAdding Columns To DataGridView's In A List?
Jan 4, 2012I 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.
