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?)

View 1 RepliesI am pulling information out of my Access Database and reading to a webpage. I need to add a update, delete, and email function to this page. I am trying to do this with the selection of a check box and buttons for each one. But I am unable to get the delete to do anything but redirect back to the orignal page. For the update I want to be able to pull the info in text boxes and just change the info and click update and it gets changed. I also want to be able to pull their email from the database and put it into a text box to be able to email right from the page. Code for show page and delete page below.

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?

Cell(3) is my checkbox. Donot consider Rows(0), at the moment I am just checking value at row 0

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.

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
