RadEditor is a third Party control. It provides many options for editing of text that we entered like changing background and fore color, size, format etc.
Using it requires just a RasScriptManager control or ScriptManager.And then use RadEditor control.
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<telerik:RadEditor ID="radeditor" runat="server">
</telerik:RadEditor>
Now if you want to suppress the inbuilt message of MaxLength validation we can use below code.
for that first add a button on whose click event write below code:
protected void Button1_Click(object sender, EventArgs e)
{
string body = radeditor.Content.Trim();
if (body.Length > 10)
{
Response.Write("<script> alert('Error: Comments can not exceed 1250 characters!')</script>");
}
}
If you dont want to count the spaces use below code:
protected void Button1_Click(object sender, EventArgs e)
{
string body = radeditor.Content.Trim();
body = body.Replace(" ", "");
if (body.Length > 10)
{
Response.Write("<script> alert('Error: Comments can not exceed 1250 characters!')</script>");
}
}
If you want to do it client side using client side validation use below javascript:
<telerik:RadCodeBlock ID="RadCodeBlock1" runat="server">
<script type="text/javascript">
function chec(event) {
var editor = $find("<%=radeditor.ClientID%>");
var a = editor.get_text().length;
if (a > 10) {
alert('hi');
event.returnValue = false;
}
}
</script>
</telerik:RadCodeBlock>
And use butotn code like:
<asp:LinkButton runat="server" CssClass="form_button" ID="lbtnSave" OnClick="lbtnSave_Click"
OnClientClick="return chec(event)"></asp:LinkButton>
