Customizing A Datagridview Checkbox ?
Jun 5, 2011
I have a Datagrdiview control that is populated from values in a table. ie: One column would have a check box for weather a record has been processed using a Posted field as a boolean Check box. My problem as that I need this field to also show the results if the record is rejected or not. [B]I am trying to have the box unchecked if the record has not been posted. Checked if the record has been posted Or be Marked with a red X if the record has been rejected.The rejected field is of course in another column in the table.

We are using the DataGridView Control for our projects. The Applications we are developing is the replacement for the Existing CLI (Command Line Interface Applications) written using FoxPro.The users are much more familiar with the Keyboard Navigations ratherthan using Mouse and all.Here What we need is, how can we handle the Keyboard Operations in the Data Grid View. Some of the Operations i am listing below.When we hit Enter Key :
1. Navigating the Cursor into a particular Cell (It will be in the Same Row, but Different Order), after getting focus the cell should become editable
2. Navigating the Cursor to the Next Row and First Column (Once i finished the editing in the Last Column )
3. Focusing the Cursor into a Specifc Row and a column. (With Editable)

I have some DataGridView code written in vb.net. (Nothing is attached to a datasource.)The 4th column is a checkbox cell.How do I detect if that checkBox is checked or unchecked?This code strangely reports TRUE or FALSE at random times. It even turns ON the checkbox in rows other than the row I clicked in. (Huh?)
Private Sub DataGridView1_CellContentClick(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DataGridView1.CellContentClick
Dim whichGrid As DataGridView = CType(sender, DataGridView)
[code].....
I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.

is it possible to have a background image repeat it's self for every listing in a combobox? so when i click the arrow on the combobox, it has a a set smiley image for every added item.. maybe even a different smiley for every listed item... not sure it's possible though, maybe i have to create a self resizing form that acts like a combobox when clicked on a button.

I need to change the cell type of an unbound datagridview ROW to checkbox type at runtime. Optionally adding a row of all checkboxes or changing the default type to checkbox is also fine. I see many examples for setting a column type to checkbox but I don't see anything that operates at the row level. Even operating at the cell level would be fine.

I have the code below which works fine when checkbox at Cell 2 is Checked ie., the date is inserted in Cell 9. Now, when I unclick Cell 2 I want the Cell 9 to be cleared. Presently, it is not cleared after unchecking. The code highlighted in Red is the area I reckon I have a problem...
Code:
Private Sub DgvReturns_CellClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles DgvReturns.CellClick
If e.ColumnIndex = 2 Then

I have a tbl called tblProjectpatients which also has 2 fields Yes and No (these have the data type - Bit). These two fields have been populated with false and true values. On my form, I have a datagridview which is populated with various values from tblProjectpatients. The problem am facing is that the checkbox's for Yes and No on the datagridview are empty at runtime eventhough at the backend they have either False or True values. I am expecting the checkbox showing on the datagridview to be either checked or Not Checked depending on the True or false values.

sample_form.rtf (1.48MB). Number of downloads: 36. I have a working form to give specific choices to the user and retrieve the user's choice. (See code below and attached image in WordPad file.) I know I can use a global ("Public") variable to pass the text of the three choices from the calling form to the called form, but is there a way to pass these from one form to the other exclusively? Of course, my main objective is to have as little memory being used as possible. I would like to make the form in my example (frmDialogChoice) a generic form that can display any set of three choices.
code within calling form:
Dim intSwitchToMake As Integer
Dim insFrmDialogChoice As New frmDialogChoice
insFrmDialogChoice.ShowDialog()

I have appended a column of checkboxes to a DataGridView using the following:
Dim chk As New DataGridViewCheckBoxColumn
DataGridView1.Columns.Insert(0, chk)
How do I change the checked state of a particular checkbox?
I have tried using the following code:
Dim val2 As DataGridViewCheckBoxCell = DataGridView1.Item(243, i)
val2.Value = True
DataGridView1.Item(243, i) = val2
The last line resulted in runtime error "InvalidOperationException was Unhandled
Cell provided already belong to a grid". Index 243 exists.

I've created a Datagridview bound to a Datatable. This Datatable is updated by a event to reflect statistical information as it changes (sub second resolution). I have a checkbox to determine if a row is available for other functions and can be toggled on and off normally if my eventhandler is not receiving my updates.
If my bound Datatable is changed, the checkbox returns to its previous state as soon as the cursor or focus leaves the checkbox glyph (not the cell).
How do I toggle the checkboxes without them reseting without disconnecting my eventhandler?

There is an OK button
I need to get message of showing which rows user has checked. The message should appear when user clicks OK button. There could be several message, checking each row one by one, in a loop.
I am not able to get this message. I tried following code in OK button
Dim strCB As String = dgvChooseQs.Rows(0).Cells(3).Value.ToString
Cell(3) is my checkbox. Donot consider Rows(0), at the moment I am just checking value at row 0

I have created a Datagridview by dropping in from the Datasource. After I changed one column to be a Checkboxcolumn but it does not represent the values. In the table (smallint) I have 0s and -1s but it doesnt matter what I enter as True and False Value in the column it just shows that the box is checked.

I have a DataGridView that collects all kinds of data from my database. This data is then summed up and grouped by name...
I would like to add a column of chckboxes in the front of my DataGridView that does not control anything. This way I have a DataGridView that combines all sorts of info grouped up, and the user may then check the checkbox infront of the spesific data he wants to print.
So it's basically a row selection checkbox....

I am using Visual Studio 2008, Vb .Net 3.5 and MS Access 2003.I have a datagridview (DGV) control bound to this MS Access DB. One of the queries is bound to this grid. Everything works fine, the data is displayed correctly. Here's the problem The SELECT statement of query has a BOOLEAN column which is shown as a check box on the grid (this is exactly what I wanted to be shown), when user clicks one of the check boxes all the records are updated. For example, if 30 rows are displayed and user changes stuats column from FALSE to TRUE for only 2 records all records in the table are set to TRUE.I have set the UPDATE command for this query's table adapter using the DataSet designer as "UPDATE <table> SET Status=?"
Can you please help me resolve this. All that I want is only those rows should be updated which are changed on the grid. Below is my code

I have a DataGridView with a checkbox column. I want to capture the value of the checkbox immediately when user changes it by clicking. I tried several events (CellValueChanged, CellClicked, CurrentCellDirtyStateChanged etc.) but nothing worked.
This is my code:
If dgvIDsTBC.CurrentRow.Cells(2).Value = True Then
MsgBox("True")
End If
