Solution 1

Try using this:

C#

<asp:image id="Image1" runat="server" style="height: 80px; width: 100px;" imageurl="<%# string.IsNullOrEmpty(Eval("ImgName")) ? "~/images/default.png" : String.Format("~/Upload/Docters/" + Eval("ImgName")) %>" />

Hope it will be helpful !!

it is giving this error
the best overloaded method match for 'string.IsNullOrEmpty(string)' has some invalid arguments

Try this instead of string.IsNullOrEmpty(Eval("ImgName"))

string.IsNullOrEmpty(Convert.ToString(Eval("ImgName")))

i have tried it before you telling bro

Guptha Ch 23-Sep-13 4:26am

It worked or not?

Mohd Arif Khan 23-Sep-13 4:27am

nope

Guptha Ch 23-Sep-13 4:34am

Eval("ImgName").ToString().Equals(null)
or
Eval("ImgName").ToString().Equals("")
or
Eval("ImgName").ToString().Equals(string.Empty)
Try these
one should work
