Hi micah,

Please refer the below link and first understand the logic after that implement in your code.Don’t copy paste code.

Hide Image if Eval is Null in ASP.Net

your solution doesnt work for other browsers except chrome and firefox

i tried this code but is showing error

if (!string.IsNullOrEmpty((e.Item.FindControl("USERPOSTIMAGE") as image).Text))
{
     (e.Item.FindControl("hidspostimage") as Panel).Visible = true;
}
else
{
     (e.Item.FindControl("hidspostimage") as Panel).Visible = false;
}

error

Error	96	'System.Web.UI.WebControls.Image' does not contain a definition for 'Text' and no extension method 'Text' accepting a first argument of type 'System.Web.UI.WebControls.Image' could be found (are you missing a using directive or an assembly reference?)

micah says:

<asp:Image ID="Image3" runat="server" class="" Style="width: 100%" ImageUrl='<%# "UserImage/"+Eval("ImageName1")%>' /> 

 Replace above code with below.

HTML

<asp:Image ID="Image3" runat="server" Visible='<%#(Eval("ImageName1")).ToString()!="" ? true : false %>'
    Style="width: 100%" ImageUrl='<%# "UserImage/"+Eval("ImageName1")%>' />

please forget this code is not working

i gave example above, i need to correct the error please

if (!string.IsNullOrEmpty((e.Item.FindControl("USERPOSTIMAGE") as image).Text))
{
    (e.Item.FindControl("hidspostimage") as Panel).Visible = true;
}

else
{
    (e.Item.FindControl("hidspostimage") as Panel).Visible = false;
}

I also tried another example but still showing error code

 <asp:Image Visible='<%# (Eval("ImageName1") == null ||  Eval("ImageName1") == String.Empty) ? "false" :"true"%>' ID="Image4" runat="server" width="100px"
                ImageUrl='<%# Eval("ImageName1") %>' GenerateEmptyAlternateText="True"
                EnableViewState="False" /> 

error
