Hi Unni,

I tried follwing appraoch in order to prevent the special characters entering in filer textbox.

CS:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridFilteringItem)
    {
        GridFilteringItem fItem = (GridFilteringItem)e.Item;
        foreach (GridColumn col in RadGrid1.MasterTableView.Columns)
        {
            (fItem[col.UniqueName].Controls[0] as TextBox).Attributes.Add("onkeyup", "CheckSpecial(this, event)");
        }
    }
}

JavaScript:

<script type="text/javascript">
function CheckSpecial(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;
    }
}
</script>
