禁用时如何更改asp按钮颜色，默认情况下按钮将在UI上禁用

Question

<asp:Button ID="btnSubmit" runat="server" Text="Save" 
     CssClass="buttonNormal buttonChange" OnClick="submit_Click" 
     Enabled="false" ToolTip="Please click on the left button to enable save" />

On startup save button will be rendered as disabled, on click of other button, the "Save" button will be enabled.

Functionality is working as expected, but there is no difference in button view whether it's enabled or disabled.

Cannot write the color change logic in CS file because this button will be rendered on start of application.

Can someone help with this issue?

TIA, Kal.

In your submit_Click function, you could add;

using System.Drawing;
...
if(btnSubmit.Enabled == "False"){
   btnSubmit.BackColor = Color.Blue; // or btnSubmit.BackgroundColor = Color.Blue;
}
else{
   btnSubmit.BackColor = Color.Grey; // or btnSubmit.BackgroundColor = Color.Grey;
}

You can initially set the color like this;

<asp:Button BackgroundColor="Blue" ID="btnSubmit" runat="server" Text="Save" 
     CssClass="buttonNormal buttonChange" OnClick="submit_Click" 
     Enabled="false" ToolTip="Please click on the left button to enable save" />
