Question

i need to get the user to click OK or CANCEL:

protected void Button1_Click(object sender, EventArgs e)
    {
        CallRecursive(TreeView1);

        string confirmationMessage;
        confirmationMessage = @"Please review the data before submitting:" +  "\r\n"
        + "Sample Received Date: " + received_dateTextbox.Text + "\r\n"
        + "Site of Ocurrence: " + site_of_occurrenceTextBox.Text + "\r\n"
        + "Occurrence Date: " + occurrence_dateTextBox.Text + "\r\n"
        + "Report Date: " + report_byTextBox.Text + "\r\n"
        + "Specimen ID: " + spec_idTextBox.Text + "\r\n"
        + "Batch ID: " + batch_idTextBox.Text + "\r\n"
        + "Report Initiated By: " + report_byTextBox.Text + "\r\n"
        + "Problem Identified By: " + RadioButtonList1.SelectedValue + "\r\n"
        + nodetexts;

        HiddenFieldConfirmation.Value = confirmationMessage;

************i need function ConfirmWithUser() to run here from javascript*************


            if (HiddenFieldUserConfirmed.Value != "no")
        {
            SubmitData();

            CallRecursive(TreeView1);
            nodetexts += ";";
        }
    }

here is the javascript:

function ConfirmWithUser() {
            if (confirm(document.getElementById('HiddenFieldConfirmation').value) == true)

                            { document.getElementById('HiddenFieldUserConfirmed').value='yes'; }

                                else

                            { document.getElementById('HiddenFieldUserConfirmed').value='no';}

how do i run this function ConfirmWithUser() on the button click inside of the code behind code as shown above:

another words i need:

1. after user clicks button, first part of codebehind execeutes
2. javascript inside of codebehind exeuctes
3. the last part of code behind executes

There is no Javascript variable named confirmationMessage.
You need to call HttpUtility.JavaScriptStringEncode and insert the server-side variable’s value as a Javascript string literal.

However, your design cannot possibly work; the if (HiddenFieldUserConfirmed.Value != "no") will run (on the server) before the Javascript client-side code.

You need to understand how HTTP and client/server separation works.
