Display image in gridview using ImageField

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;
        }
        
    }

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>

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
