Easiest would be if you use Javascript/jQuery to do that.

Have a onchange event of Grid textbox wired up to a Javascript method. In that compare the value entered and based on it display the prompt or take any necessary action.

Use Javascript.

Say the id of the outside textbox is txtoutside.

Now OnBlur or OnChange event write

onchange ="javascript:return checkValue(this);"

function checkValue(obj)
{
   if(obj){
      var elemoutside = document.getElementById('txtoutside');
      var thistextval = parseInt(obj.value);
      var outsideval = parseInt(elemoutside);
      if(outsideval <= thistextval) {
          
          return true;
      }
   }
   alert('Invalid entry');
   return false;
}

this would help I think.

Solution 3

You need to write the javascript on keyPress event of textbox which is in Template Field
Just use event.keychar in script to check whcih key get pressed.
allow only numric keys (keyCode = 47-56)
