Custom Text Source
RadSpell is not limited to spellchecking HTML elements only. You can also define a custom text source to provide text for spellchecking. Using a custom text source allows you to spell check virtually anything on the web page that you can access programmatically. See the live demo for an example of spell checking a text area and placing the corrected text in a different control.
To implement spellchecking for text sources other than HTML, define a JavaScript object with two methods, get_text() and set_text(text), and then use the set_textSource(textSource) method of the RadSpell client-side object.
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
function MySpellSource()
{
this.get_text = function()
{
return "colourful mistakrn texr";
}
this.set_text = function(text)
{
alert("The corrected text is: " + text);
}
}
function spellCheck()
{
var spell = $find('<%= RadSpell1.ClientID %>');
spell.set_textSource(new MySpellSource());
}
</script>
</telerik:RadCodeBlock>
<body onload="setTimeout(function() { spellCheck(); }, 100);">
<form id="form2" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<div>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<telerik:RadSpell RenderMode="Lightweight" ID="RadSpell1" runat="server" ControlToCheck="TextBox1" />
</div>
</form>
</body>
