GridTemplateColumn ItemTemplate Visibility

[Josh]

I have a RadGrid that has one "Comments" TemplateColumn.  I have an image
in the item template that has the tooltip set to the actual "Comments" text.  Since
not all rows have "Comments" in the Sql Table, I was wondering if there is a way
to hide the image if the Text="" or is null.  Possibly something straight in the
image Visible="<% ???????? %>" Any ideas?  Thanks is advance.

Hi Josh,

Try the following code for setting the visibility based on the cell value.

ASPX:

<telerik:GridTemplateColumn>
<ItemTemplate>
    <asp:Image ID="Image1" runat="server" ImageUrl="~/Images/Image1.gif"  Visible='<%# (DataBinder.Eval(Container.DataItem,"Comments") == "" ) ? false : true %>'/>
</ItemTemplate>
</telerik:GridTemplateColumn>

Thanks,
Shinu.

The code did not work for me, however, I was able to get it to work with the below code:

ASPX Control
Visibe='<%# VisibleOrNot(DataBinder.Eval(Container.DataItem, "Comments").ToString())%>'
Code Behind
public bool VisibleOrNot(string commentdata)
{
    if (commentdata == "")
        return true;
    else
        return false;
}
