Hi guys, i have a problem ... I started to create a webform with lots of Button and TextBoxes on it. Now i have an array with some int values (Color-Values) and i try to change the colors of the buttons and textboxes. I know how i can change the color-property for one button i named, but i would do it automatically. All Buttons have the ID "signal" + number I remember VB or VBA ... there i could use Me.Controls("signal"+i).BackColor = "Value" //for example I'm looking for an equal command in C# ---------------------------------------------------- for (int intI=0;intI

Control myControl1 = FindControl("signal" + i); myControl1.BackColor = Color; Normally the C# commands are the same as VB just a little different in syntax.

Hi Homer You will have to parse your control to access its value like following ((Button)FindControl("signal" + number)).BackColor = Color.Red; Hope this helps.

Thx for your reply Ken, maybe the way i explained it was not the right one ... First of all, the idea is not bad, but the main point i'm searching for isn't solved. I tried to set the BackgroundColor of (for example) 10 Buttons. These Buttons named signal1,signal2,...,signal10. Ok, i can solve it and can set the BackgroundColor for each button manually ... (signal1.BackColor = Color.Red, ... ), but because of i have over 100 buttons i would do it automatically. So i tried serveral combinations of this.Controls(.BackColor), Page.FindControl(.BackColor),myobj.ID(.BackColor) ... but i couldn't find a way to get this BackColor - property after the "." (shown in the Listbox which opens after .) i'm searching for an command which is equal to the vb command Me.Controls("signal" + number).BackColor = Color; Hope that you now can follow my thoughts ... sorry for bad explanation at the first time. Any ideas are welcome. Thank you very much!!! homer
