Is there some property of a radtextbox that can be retrieved in the codebehind that indicates whether the value has been modified?  for a password field, I need to know if it has been modified, and if it has not been modified, not modify the password store on the back end.

Hi John,

The OnTextChanged event only occurs if the value of the RadTextBox control actually Changes from there you can access the modified text. Please have a look into the following code that I tried to access the modified text in code behind.

ASPX:
<telerik:RadTextBox ID="RadTextBox1" runat="server" Text="Value1" AutoPostBack="true"
    OnTextChanged="RadTextBox1_TextChanged">
</telerik:RadTextBox>

C#:
protected void RadTextBox1_TextChanged(object sender, EventArgs e)
{
    string  modifiedText;
    modifiedText = RadTextBox1.Text;
}

Thanks,
Shinu.

Sorry.  I already know how to capture on changed on both the client in javascript and in the codebehind in c#.  I was hoping that there would be a property of the control that I could retrieve rather than capturing the event in javascript and then setting the value of a hidden control that I would then retrieve on form submission.  This is particularly important for password fields because the text in a password cannot be set from the codebehind.

Hello John,

There is no available property that will indicate either the input has changed or not. The only possible approach is the one that Shinu have shown and for your particular requirement, as you have mentioned, you could use HiddenField to store the previously entered password and compare the new value with the value from the HiddenField when needed.

I will be glad to assist if other questions arise.
