If you want to do it in javascript then:

var Label1 = document.getElementById("<%=Label1.ClientID%>");
           
Label1.style.color = document.getElementById('txtColor').value;

Code-Behind:

Label.ForeColor = txtColor.Text

 Hi frds,

Thank you very much for your replies. I have gone through these links.

you can run a loop on all label controls somehting like this

Public Shared Sub ResetFormValues(ByVal parent As Control)

For Each c As Control In parent.Controls

If c.Controls.Count > 0 Then

ResetFormValues(c)

Else

Select Case (c.GetType().ToString)

Case "system.Web.UI.WebControls.Label"

CType(c, Label).ForeColor = Drawing.Color.Maroon

Exit Select

End Select

End If

Next

End Sub

Do you want to change it permanently or just for one time?

Secondly, Do you want to do it with javascript or code-behind?

 hi

could you please tell me "ResetFromValues " method from where i need to call?

if possible please send me c# code....(dont mind if i am asking too much).

if a user changes colors and back ground  it should appear only to him. Just like iGoogle.

User can set his own custom settings. it can be javascript or c#.

private void ResetFormValues(Control parent, selectedColor String)
    {
        foreach (Control c in parent.Controls)
        {
            if (c.Controls.Count > 0)
            {
                ResetFormValues(c);
            }
            else
            {
                switch(c.GetType().ToString())
                {
                    case "System.Web.UI.WebControls.Label":
                        ((Label)c).ForeColor =  selectedColor; 

                        break;    
                }             
            }
        }
    }

 

You can call this function when user change the color of one Label as you see i put another parameter as selectedColor so when

user change color of a label call this function and pass the color parameter it will change all the label colors....
