Hi could you help me please. I need to write condition on client side within GridView itemtemplate.

<% if(Eval("item").Contains("keyword"){%>

<img src='<# Eval("imagepath") %>' />

<%}
else if(Eval("item").Contains("keyword2")){
%>
<img src='<# Eval("imagepath2") %>' />

<%}%>

Use a code-behind function to return a boolean.

ASPX:

   <img src='/path1.jpg' id="img1" runat="server" 
         visible='<%# ShowImg1(Eval("Item")) %>' />

    <img src='/path2.jpg' id="img2" runat="server" 
         visible='<%# ShowImg2(Eval("Item")) %>' />

Code-Behind:

protected boolean ShowImg1(object item)
{
     bool result = false;
     string item = object as string;
     // do your checks and return true or false;

     return result;
}

protected boolean ShowImg2(object item)
{
     bool result = false;
     string item = object as string;
     // do your checks and return true or false;

     return result;
}
