i tried this approach but it changes nothing and gives no error please correct it : public void checkSuites() { try { Dictionary int , Control> btnList = new Dictionary int , Control>(); btnList.Add(1, Button1); btnList.Add(2, Button2); btnList.Add(3, Button3); SqlCommand checkSuite = new SqlCommand( "SELECT * FROM tablesstatustbl WHERE tabestatusint='0'" , cn); SqlDataReader readSuite = checkSuite.ExecuteReader(); while (readSuite.Read()) { int suiteIndex = Convert.ToInt32(readSuite[ "tabestatusint" ]); string suitePath = "tabestatusint" + suiteIndex; foreach (Button key in btnList.Values) { if (key.Name == suitePath) { key.Image = My_Café_Manger.Properties.Resources.tablesbusy; } } } }

Hi Mind, Yes I understood your requirement clearly now, Just write a function like this, before that add two images in your resource folder which is represents available and busy, Loop the table status value and identify any status is busy, get the id and change the button image depends on that, ex : if id 2 is busy, set the button id like button2 and write the below code button+id.BackgroundImage=(( System . Drawing . Image )( Properties . Resources . Image ));
