Restrict special characters

[Venkatesh]

Hi,
How to restrict special characters in  rad grid?
I have the UI as below:

<telerik:GridTemplateColumn DataField="ProductNumber" HeaderText="Product Number"
                            UniqueName="ProductNumber" Visible="true">

 <InsertItemTemplate>
                                <telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text="">
                                </telerik:RadTextBox>
                            </InsertItemTemplate>

                            <EditItemTemplate>
 <telerik:RadTextBox ID="RadtxtPrdNumber" runat="server" Text='<%# Eval("ProductNumber") %>'>
                                </telerik:RadTextBox>
                            </EditItemTemplate>

<ItemTemplate>
<telerik:RadTextBox ID="RadtxtPrdNumber" ReadOnly="true" runat="server" Text='<%# Eval("ProductNumber") %>' />
  </ItemTemplate>
                        </telerik:GridTemplateColumn>

I want to restrict the special characters in InsertItemTemplate and EditItemTemplate.

Thanks

Hi,

Try the following javascript to restrict special characters.
JS:

<script type="text/javascript">
    function OnKeyPress(sender, eventArgs) {
        var char = eventArgs.get_keyCharacter();
        if (char == '$' || char == '#' || char == '^' || char == '[' ) {
            eventArgs.set_cancel(true);
        }
    }
</script>

Regards,
Shinu.

Hi,
Is there anything generic. I want to restrict special characters like !@#$%^&*()|\/

Also how to invoke this javascript?

Hi,

  I suppose you want to allow alphabets only in radtextbox. You can hook the client event as shown below.
aspx:

<telerik:RadTextBox ID="RadTextBox1" runat="server">
            <ClientEvents OnKeyPress="OnKeyPress" />
</telerik:RadTextBox>

JS:

function OnKeyPress(sender, args)
{
         var c = eventArgs.get_keyCode();
        if ((c < 65) || (c > 90 && c < 97) || (c > 122))
            eventArgs.set_cancel(true);
}
