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 have a DataGridViewCheckBoxColumn who's column name is "booReadyToReport want to hide all the checkboxes in this column if "bintAnalyteCodeID" doesn't equal the selected value in a combobox on my form. ut I run this bit of code the DataGridView DataError event fires currently, have nothing in the event except an comment. he code seems to work, but I'm new to VB.NET and I'm wondering if this is the correct way to handle thishould I use the CellPainting event?

For Each dr As DataGridViewRow In Me.dgvCalculatedResults.Rows
f dr.Cells("bintAnalyteCodeID").Value = Me.cbxAnalyte.SelectedValue Then

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)

I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
I want to create a solid checkbox that is checked by default, and is not clickable. If you click it, nothing will happen . how to do this?
View 2 RepliesI would like to use code to create a checkbox with default properties and place it at a certain position in a groupbox. For example, i would like to do this by pressing a button and that i can give in the name and tag by use of an imputbox. Also, i have noticed that if something like this is done, these changes aren't permanent and don't apply to the designer nor the code in VB. Is there a way to let the newly created checkboxes appear in the designer? And what about permanently deleting checkboxes by pressing a button. With "Dispose()" it isn't deleted from the designer...

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.
View 1 RepliesI 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...

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.

I just want to know on how will I add a Checkbox in each row of my datagridview. First I used a datatable to get all the values from my database and then pass it all to the datagridview. What I want to happen is at the first column of my datagridview there is the checkbox.[code]
View 4 RepliesI'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?

View 1 RepliesI 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
