DataGridView DataGridViewCheckBoxColumn Copy Columns?

Feb 7, 2012

I have a datagridview that is bound to an access database. The first column is a checkbox, the second is first name, the third is last name, the fourth is start time, and the fifth is end time. Is there a simple way that can either be explained to me, or demonstrated with some example code to have the data copied from the first name, last name, start time, end time when the checkbox is checked in the corresponding row? (there are other columns in the datagridview, but i only want the first four cells copied that are in the same row as the checkbox to be transferred to the second datagridview. This would also have to be able to work for each checkbox in each row)

Mar 1, 2011

I have a scenario where-in I have a DataTable with certain columns "Col1, Col2, Col3". I want to copy just "Col2, Col3" into another DataTable which has a primary key "ID". What is the best way to copy them. There are 5000+ records and performance is a key factor.I tried with Select, DefaultView.RowsFilter but no success. I know one option is to loop through all records an copy data one by one in second DataTable. But wanted to know a better way.

DataGridViewCheckBoxColumn Not Showing Up?

Jun 2, 2011

It's been a while since I've had to add a CheckBoxCol to a DataGridView, so I copied and pasted the code directly from the example shown in the MSDN library page here: [url]Anyway -- the column is added as expected however, there is no checkbox! (see the column "Accept" in the image I've posted). I was hoping I am missing something easy/obvious, and I've had success with this before in other apps so this is becoming frustrating.DGV's Datasource is set to a datatable found in a Dataset. Everything loads just fine. No errors.

DataGridViewCheckBoxColumn, Allow Only One Check In Entire Column?

Oct 13, 2009

I have a DataGridViewCheckBoxColumn and I am trying not to allow more than one checked boxes in the column. So after one is checked, when user tries to check another one, i want to prevent that and not have more than one checked box in entire column. I used whole bunch of events but nothing is helping me... Some time it seems working but if i double click the checkbox, it puts the checkbox... sometime it puts the check mark on my third click (not on first, not on second but on third...) What i want is only one checked box and if use tries to click another one don't let it happen.

CheckBox In DataGridViewCheckBoxColumn Won't Change To False When Clicked

Jan 9, 2012

For some reason, I can't change the checkbox from True to False when I click the checkbox in my DataGridViewCheckBoxColumn called "Select". I setup my DataGridView (dgvWBFOrphans) with 5 TextBox columns that are Read-Only and 1 CheckBox column that is not Read-Only. I use a stored procedure and data reader to load the DataTable which is used as the DataSource for dgvWBFOrphans. I want all the checkboxes to default to True and allow the users to uncheck certain rows in the "Select" column.

Dim dtOrphans As New DataTable
Using cnn As New SqlClient.SqlConnection(clsDBConn.clsDBConnections.prpConnString)
cnn.Open()

Specify Datagridview Columns By Name?

Nov 30, 2009

I'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?

DataGridView Is Displayed With Four Columns?

Jul 18, 2010

I 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.

Preserve Columns At DataGridView?

Sep 1, 2011

I�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, 2010

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?
