RadSpell can be easily configured to check any server- or client-side editable element, by setting its ControlToCheck property. to the ID of the respective element. By default every instance of RadSpell can check only one control. However, you can configure RadSpell to check multiple controls at once.
Example
The general way to set a control to check is by setting the ControlToCheck property directly in the RadSpell tag:
|
<asp:textbox id="TextBox1" runat="server" ... />
<rad:radspell id="RadSpell1" runat="server" controltocheck="TextBox1" />
|
Checking multiple controls at once
Using the client-side API of the control you can setup a text source for checking multiple controls at once:
<asp:textbox id="TextBox1" runat="server" ... />
<asp:textbox id="TextBox2" runat="server" ... />
<rad:radspell id="RadSpell1" runat="server" ... />
