How do you distinguish between yorself and other user? My simple guess is via session? If it's correct then add a javascript validation or server side validation to flag an error if user is other than you and has selected ---- Select ---- Option.

Ranjith please can you clarify your question. Do you want that you can select the option ---Select--- and user should not able to select. Or you want that ---Select--- should display but no one should select it and you want it to show ---Select--- for information purpose only.

Hi Ranjith,

Please try this.!

C#

// If you want a list of options to be disabled 
foreach ( ListItem item in dropdownlist.Items )
{
    if ( //condition if item's value == 0)
    {
        item.Attributes.Add( "disabled", "disabled" );
        // or
        // item.Enabled = false;
    }
}

or

C#

// Specifically for the 1st option. Throws error when you dont have any options in the dropdownlist. So, becareful with this.
dropdownlist.Items[0].Attributes.Add("disabled", "disabled");

If not the above, please do try the below one.

C#

item.Enabled = false;

Personally, I've not checked it but should work fine. Let me know if you have any issues. I've provided "disable using attributes" and "Enable" options. Please test it for yourself with both options and use the best one that suits your application.

Thank you,
RelicV
