Hi,

Try the following code to remove special characters while filtering.
C#:
protected void RadGrid1_ItemCreated(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
 if (e.Item is GridFilteringItem)
 {
   GridFilteringItem filterItem = (GridFilteringItem)e.Item;
   (filterItem["UniqueName"].Controls[0] as TextBox).Attributes.Add("onkeyup", "CharacterCheck(this, event)");
 }
}
JS:
function CharacterCheck(text, e)
{
  var regx, flg;
  regx = /[^0-9a-zA-Z'' ]/
  flg = regx.test(text.value);
  if (flg)
  {
    var val = text.value;
    val = val.substr(0, (val.length) - 1)
    text.value = val;
  }
}

Thanks,
Shinu.
