AJAX :: Server Side Confirmation - Not Control Initiated

Sep 25, 2013

URL...In the above page, the button fires the javascript first, then the code-behind sub runs.  The problem I have is I am in the middle of a code-behind sub routine that checks if a user is logged on the a PC.  If there is a users logged on, I want the confirm popup to ask whether to reboot anyway or cancel.  The code needs to dictate whether to call the javascript, not some direct button click.  Then I need the remainder of the code-behind sub to execute based on the users choice. 

I can call the client script in the code-behind sub using 'RegisterStartupScript...'; then I can get the page's form value.  The problem is that the sub runs to completion without waiting for the javascript code to run.  This causes code-behind variable to get checked before it's set by the client and it nevers works.

AJAX :: Show Server Side Yes No Confirmation Box Using Script Manager

Feb 5, 2014

I am throwing a alert box using scriptmanager like this based on some condition.

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "alertMessage", "alert('Would you like to be put on the wait list?')", true);

But it has only "ok" button. Is there a way to display a message box which has yes/no buttons so that I want to check some more conditions in the code behind.

something like this.

DialogResult result = MessageBox.Show("Do you wanna do something?", "Warning",
MessageBoxButtons.YesNoCancel, MessageBoxIcon.Warning);
if(result == DialogResult.Yes) {
//code for Yes
} else if(result == DialogResult.No) {
//code for No
} else if (result == DialogResult.Cancel) {
//code for Cancel
}

Web Forms :: Display Server Side Yes No Confirmation Box On DropDownList Change

Apr 16, 2013

I was wondering if there is a way to capture the yes/no values on the server side once the y/n buttons are clicked on a javascript pop up?

I am displaying the y/n pop up while using a dropdown menu but pretty much all the solutions i have seen so far use button's onClick event.

By reading article: [URL]

I am able to see the pop up box with the yes/no options but after i click a 'yes' or 'no', i don't see  'You clicked Yes' or 'You clicked No'.

This is the code i have so far which has been taken from Muddassar's article that uses a button, not a drop down.

I can see for button the "Confirm()" is being called by OnClientClick event, but i haven't been able to make it to work in a dropdown.

On the aspx page:

<asp:DropDownList ID="ddlWorkBucket" runat="server" AutoPostBack="true" DataSourceID="SqlDataSource8" DataTextField="workBucketName" DataValueField="workBucketID" Width="120px" onChange="Confirm()" OnSelectedIndexChanged="OnConfirm"></asp:DropDownList>

Also on the same aspx page is this javascript function:

 <script language ="javascript" type="text/javascript"> 
function Confirm() {    var confirm_value = document.createElement("INPUT");   
confirm_value.type = "hidden";    confirm_value.name = "confirm_value";   

[CODE].....

Apr 29, 2014

 I am trying to use Yes No Confirmation Message Box but the code below here which i found here uses a button to raise the confirmation message box but what i would like to use is a DropDown.  How can i modify the code and i use drop-down box instead of using a button? here is the javascript code: 

<script type = "text/javascript">
function Confirm() {
var confirm_value = document.createElement("INPUT");
confirm_value.type = "hidden";
confirm_value.name = "confirm_value";

[code]....

but here is what i would like to use is drop-down instead of the button:

<asp:ListItem Text="test1" Value="test1"></asp:ListItem>
<asp:ListItem Text="test2" Value="test2"></asp:ListItem>
<asp:ListItem Text="test3" Value="test3"></asp:ListItem>
</asp:DropDownList>

Get IP Of Server That Initiated Redirect

Jul 26, 2010

A user clicks a hyperlink in a page. Server A handles the request and redirects the client to a URL on Server B (more specifically I am using the Response.Redirect method in .NET on server A). I have been asked to restrict access to Server B to redirects originating from Server A only (by blocking IP's other than Server A's). At first I thought this could be achieved by using the HTTP 'referer' header, however, it seems it is up to the browser to set this to a URL (rather than IP), and it is not guaranteed to do so.

I guess there is no way to set the HTTP 'referer' on server A in .NET (to server A's IP)? (my intuition is that would be a security hole). So my question is, how can I restrict access to Server B to redirects originating from Server A?

How To Return A Rendered Panel Control Content From Server-side As A Result Of JQuery.ajax()

Jun 22, 2010

At first, I should confess that I am not sure if it is a good practice or not. I have came out with the idea due to my practice of jQuery.ajax().

What I want to achieve is depended on this design:

//Server Side; an .asmx file contains a method like this:
[WebMethod]
public string NewContent(string parameter)
{
string renderedHTML = string.Empty();
switch(parameter)
{
case ("person"):
// create an asp.net panel with
// some controls in it that has form elements to enter person data
// render control and assign its html to renderedHTML
break;
case ("department"):
// create an asp.net panel with
// some controls in it that has form elements to enter department data
// render control and assign its html to renderedHTML
break;
}
}

And from the client I want to do this:

// Some html in the page
<script type="text/JavaScript">
jQuery.post('ajax/myWebServices.asmx/NewContent'
function(returnedPanelContent) {
$('.result').html(returnedPanelContent);
});
</script>

Question is:

How can I make it work? Briefly to have a webservice method that returns different asp.net Panel control content created programmatically so that I can get this control rendered as HTML in my client-side and insert it to my web page?

Server Side Control Hidden - Possible To Read Values Client Side

Jan 30, 2010

I've got two textboxes running server side and have their visibility turned off. I'm using a couple of ASP.NET controls which require the textboxes to exist. However, I am filling them from the code behind and would not like the user to see this. Can the user turn the visibility on and see the values entered in the text box? I tried using FireBug, and I couldn't seem to select the visibility option in order to edit it. However, I'm quite new to Firebug, so there may be another way? Or does running it server side mean that the client can't ever view the contents of the textbox?
