Hi Joslyn,

Below is a sample code snippet that I tried ,on the TextBox OnBlur event I'm checking the characters being entered and clearing other characters.

ASPX:

<telerik:GridBoundColumn UniqueName="ShipCity" DataField="ShipCity" CurrentFilterFunction="Contains"
 ShowFilterIcon="false" AutoPostBackOnFilter="true" HeaderText="ShipCity"  />

C#:

protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
    if (e.Item is GridFilteringItem)
    {
        GridFilteringItem filterItem = (GridFilteringItem)e.Item;
        (filterItem["ShipCity"].Controls[0] as TextBox).Attributes.Add("OnBlur", "CharacterCheck(this, event)");
    }
}

JS:

<script type="text/javascript">
    function CharacterCheck(text, e) {
        text.value = text.value.replace(/[^0-9a-zA-Z]/gi, '');
    }
</script>

Thanks,
Princy
