The server tag is not well formed. When passing parameters to javascript function

Question

Hi have always trouble with calling JavaScript function with parameters values as values bonded to the gridview. I follow SO Thread But can not used for passing this

Answer 1

This works, but seems an HACK because I removed the enclosing quotes (anti-XHtml)

 onblur=<%# String.Format("return ValidateText(this, '{0}')", Eval("VehicleID")) %>

The problem is having " "" " or ' '' ' as part of the string.

This is better done (I wish it is easier in markup), in code-behind, e.g. RowDataBound or ItemDataBound

 control.Attributes["onblur"] = String.Format("return ValidateText(this, '{0}')", rowValue);

Answer 2

I think the problem is the outer-most double quotes ", change that to single quotes '.

onblur='return ValidateText(this,'<%# Eval("vehicleId") %>')'

UPDATE

Try using string.Format() as mentioned in the SO question your are refering..

onblur='<%# System.String.Format("return ValidateText(this, \"{0}\")", Eval("vehicleId")) %>'
