I have to hide/show a link based upon a value coming from database, if value from db is '0' then I have to display href link else hide it.

It tried to use if condition, but it does not work with "Eval".

Below code should work -

<a href="#" style="visibility: '<%#Eval("Valid")=="0" ? "hidden" :"visible" %>'">HyperLink</a>

It does not work, if I use it with LinkButton control, it throws error "Cannot convert type 'string' to 'bool'".

If used HTML anchor tag, it gives error "DataBinding: 'System.Data.Common.DataRecordInternal' does not contain a property with the name 'Valid'."

Use like given below for Link button control. Please not that "Valid" is the field name you are bounding to the control & not any property

'<%#Eval("Valid")==null ? false :(object) Convert.ToBoolean(Eval("Valid"))
