I have thiw grid view in which i load from the database 3 columns. Looks like this

C#

ID|  Server| Status
 1|  Tm2323|  checked
 2|  Tm2356|  unchecked
 3|  Xg2355|  checked
 4|  Hgd345|  checked

So i want to do this uncheck or check a server in the third column of the gridview, and after thath when i click a submit button that i have in my app the, database to get updated and the gridview to refresh showing the new results.
Can anyone guide me? because i've tried everything i could but i just can't make this work. I'm out of ideas.

What is checked/unchecked? Is it checkbox? If so,do you want to perform some action based on the status of the checkbox?

yes, it's a checkbox column in the gridview which i upload from the database , in the access database is't a ye/no datatype. but i've managed to solve my problem. i had only to modify a propriety when i uploaded the data in the gridview...

dataGridViewServers.ReadOnly = true; i had to change to dataGridViewServers.ReadOnly =false;

C#

string SQLString;

SQLString = @"SELECT        tblServers.ID, tblServers.ServerName, tblServers.Status
              FROM            (tblServers)";

OleDbCommand SQLQuery = new OleDbCommand();
DataTable data = null;
dataGridViewJidoka.DataSource = null;
SQLQuery.Connection = null;
OleDbDataAdapter dataAdapter = null;
dataGridViewJidoka.Columns.Clear(); // <-- clear columns
//---------------------------------
SQLQuery.CommandText = SQLString;
SQLQuery.Connection = database;
data = new DataTable();
dataAdapter = new OleDbDataAdapter(SQLQuery);
dataAdapter.Fill(data);
dataGridViewServers.DataSource = data;
dataGridViewServers.AllowUserToAddRows = false; // remove the null line
dataGridViewServers.ReadOnly = true;
dataGridViewServers.Columns[0].Visible = false;
dataGridViewServers.Columns[1].Width = 140;
dataGridViewServers.Columns[2].Width = 53;

In order to be able to check/uncheck a checkbox column imported from the data base into a datagridview, youu have to modify the underlined line of code like this:

C#

dataGridViewServers.ReadOnly = false;

. now it will work just fine.
