Having issues with Attributes.Add() function on ASP.NET platform

After adding CSS through code behind in asp.net on page_load, it works perfectly on my local environment but fails to work on the server. Here is the code snippet for your reference:

 protected void Page_Load(object sender, EventArgs e)
{
    string selectedValue = Request.QueryString["selectedValue"];
    updateCareer.Attributes.Add("style", "word-break:break-all; word-wrap:break-word");
    errordiv.InnerHtml = "";
    if (!IsPostBack)
    {
        rep_Jobs.DataBind();
    }
}

The error message I am encountering is:

'System.Web.UI.UpdatePanel' does not contain a definition for 'Attributes' and no extension method 
'Attributes' accepting a first argument of type 'System.Web.UI.UpdatePanel' could be found (are you
 missing a using directive or an assembly reference?)

Please advise on why this issue is occurring even though I have included all the necessary namespaces.

Answer №1

It appears that the issue may be due to your application running on different versions of the .NET framework. I recommend checking out the documentation on UpdatePanel.Attributes to see that this property is only available in .NET 4 and above. Versions below that will result in the error you are encountering.

To create a cross-version compatible solution, consider using a container like a Panel inside the update panel whose CSS you can manipulate. Alternatively, upgrading the server's version of .NET may also resolve the issue if feasible.
