How do I set a disabled TextBox's current text color to be the same as its current background color in C#?
Simply doing txtLala.ForeColor = txtLala.BackColor does not seems to work.
This works:
txtLala.Text = "Red";
txtLala.BackColor = System.Drawing.Color.Red;
txtLala.ForeColor = txtLala.BackColor;
txtLala.ReadOnly = true;
Try setting the color
, before the readonly
. And also check how you are setting the color!
EDIT
Try this
txtLala.Attributes.Add("style","background-color:Red;color:Red");
If you are trying to make it invisible, you know you can set it as
txtLala.Visible = False;
EDIT II
I finally tried
txtLala.Enabled = false;
... you see that grey shadow color! I don't think you can mess with that, it looks to be a browser property setting.
Why not set as ReadOnly
or Visible = False
?
Maybe you have a good reason for Enabled = false
But you should note:
Use the Enabled property to specify or determine whether a control is functional. , preventing any input from being entered in the control. ,防止输入任何输入。
Note The ability to enable or disable functionality is always available.
This property propagates down the control hierarchy. Therefore, disabling a container control will disable all child controls within that container.
Note Not all controls support this property. See the indivual controls for details.
If this is a readonly textbox, you need to explicitly set your BackColor first, then your statement will work.
txtLala.BackColor = System.Drawing.SystemColors.Info;
txtLala.ForeColor = txtLala.BackColor;

Then again, if it's readonly, a label might be better. If you're trying to hide it, perhaps setting .Visible = false
would be better still.
Edit : This seems to be a common question on the web. With respect to winforms : This site suggests dropping the box into a frame and setting Enabled = false
on the frame, not the textbox . Once you do that, you may be able to maintain control of the forecolor.
It seems to only work for TextBox that is read only. If it is disabled (.Enabled = false). It does not seems to work.
