try to display image in gridview row column by passing in Status field in the method with integer 1,2,etc

if 1, it will return filepath , so this filepath will use as string for DataImageUrlField.

but getting this error:
Databinding expressions are only supported on objects that have a DataBinding event. System.Web.UI.WebControls.ImageField does not have a DataBinding event.

aspx Gridview
-------------
 <asp:ImageField HeaderText="Status" HeaderStyle-CssClass="arialfontgvtitle" DataImageUrlField='<%# getImageByID(Status) %>' ControlStyle-Height="48" ControlStyle-Width="48"></asp:ImageField>

codebehind
----------
 protected string getImageByID(int intstatusid)
    {
        statuspic sp = statuspic.getFilePath_ByStatusID(intstatusid);

        if (sp != null)
        {
            return sp.ImagePath;
        }
        else
        {
            return String.Empty;
        }
        
    }

Instead of DataImageUrlField='<%# getImageByID(Status) %>'


write like this DataImageUrlField='<%# getImageByID(Eval("Status")) %>'
 
or else

you can use TemplateFiled  inside place a ImageButton or Image and do the same

You cannot bind a value using <asp:ImageField control.

If you want to dynamically set your ImageUrl you need to use a <asp:TemplateField.. /> like I posted below.

So basically replace your <asp:ImageField line with what I posted below and you should get your wanted result.

Hope it helps.
<asp:TemplateField HeaderText="Status" HeaderStyle-CssClass="arialfontgvtitle">
    <ItemTemplate>
        <asp:Image ID="imgStatus" runat="server" ImageUrl='<%# getImageByID((int)Eval("Status")) %>' Height="48" Width="48" />
    </ItemTemplate>
</asp:TemplateField>
