If the user responds No, I want the rest of the code in this event to not execute (which basically gets the info for the node2 they clicked) and stay at node1, instead of node2. If they respond Yes, I would like the rest of the code to execute and proceed to node2.
I can't get the radconfirm to work. I have the following code in the OnNodeClick event of the treeview.
RadAjaxManager1.ResponseScripts.Add("radconfirm('Are you sure you want to navigate to a different node without saving your data?', confirmCallBackFn);");
I have a RadAjaxManager in my markup and a javascript function as follows:
function
confirmCallBackFn(arg) {
if (arg == false) {
return
}
}
The RadConfirm box doesn't come up at all and proceeds with executing the code within the event....
How can I accomplish this with the Radconfirm? Please don't refer me to another post since I have scoured the internet & this website and am unable to find a concise way on how to do this relatively simple task. A simple code example would be great...

I have the following js:
function CheckForDataSaving() {
var result = window.confirm("'Are you sure you want to navigate away from this tree node or page without saving your data?'");
if (!result) {
return (false);
}
}
I have the following in my code-behind:
ScriptManager.RegisterStartupScript(this, this.GetType(), "confirm", "CheckForDataSaving();", true);
When executing the above code-behind (note that the page is in an AJAX script manager), the confirm dialog doesn't even show up.
Either or both responses would be appreciated. The first one is for the RadConfirm. The second reply is for a js Confirm.

Even when I specify in my function the following, it still tells me it has no value:
var myTextField = document.getElementById('hdnRecordSaved');
alert(myTextField);
When I put the full value of the variable in (ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value), I get the correct contents back ("1"), which I set in my code behind. However, I would prefer to just put the short name in since the masterpages may change, etc. Unfortunately, I know I can get around this with VS2010, but we are using VS2008.
What am I doing wrong with the js naming conventions that can't give me the contents? Here is my below js.
<

Note that the below bolded html has no trouble with the fieldnames which is in the same function.

I have this in my js on the page:
var hdnRecordSaved = document.getElementById("<%= hdnRecordSaved.ClientID%>");
I don't know why I can't access the value of the variable like the other 2 variables I have in the page if I have this set up the same way as follows:
var hdnRecordSaved = document.getElementById("<%= hdnRecordSaved.ClientID%>");
When I have it like the above (which is declared just once in a script file at the bottom of the page - see original post), the variable has no value...
I am accessing it within the aspx page itself and not an external js file.
When I include the following into the code, I get a js error.
var myTextField = document.getElementById('hdnRecordSaved').value;
alert(myTextField);
OR when I include this, I get an error:
var myTextField = document.getElementById('hdnRecordSaved').value;
alert(myTextField.value);
BUT when I include the fully qualified name, everything is fine:
alert(ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value);
For whatever reason, I can't understand why I can't get a reference to it using the shorter name when declaring it (seemingly properly) in my code (see original post)????

Here is the "view source" of the html when the page is running. The alert box doesn't pop up and my page doesn't go into my codebehind treenode click event:
<td align="center">
<div id="ctl00_ctl00_cphTopCenter_cphCenter_ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSavedPanel">
<input name="ctl00$ctl00$cphTopCenter$cphCenter$hdnRecordSaved" type="hidden" id="ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved" />
</div>
</td>
Here is the js function that executes when the node is clicked:
function onNodeClicking(sender, args) {
MappingField.innerText = args.get_node().get_text();
FieldName.innerText = args.get_node().get_parent().get_text().toUpperCase() + " ==> " + args.get_node().get_text();
//alert(ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value);
var myTextField = document.getElementById('hdnRecordSaved').value;
alert(myTextField);
//alert(ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value);
if (hdnRecordSaved.value == "0") {
alert(1);
if ((startPosition.value != "") || (endPosition.value != "")) {
alert(2);
if (confirm("Are you sure you want to navigate away from this tree node or submit functionality without saving your data?")) {
alert(3);
return (true);
}
else {
alert(4);
return (false);
}
}
}
}
When I change the variable inside the fucntion name to the fully qualified name, it works fine:
function onNodeClicking(sender, args) {
MappingField.innerText = args.get_node().get_text();
FieldName.innerText = args.get_node().get_parent().get_text().toUpperCase() + " ==> " + args.get_node().get_text();
//alert(ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value);
//var myTextField = document.getElementById('hdnRecordSaved').value;
//alert(myTextField);
alert(ctl00_ctl00_cphTopCenter_cphCenter_hdnRecordSaved.value);
if (hdnRecordSaved.value == "0") {
alert(1);
if ((startPosition.value != "") || (endPosition.value != "")) {
alert(2);
if (confirm("Are you sure you want to navigate away from this tree node or submit functionality without saving your data?")) {
alert(3);
return (true);
}
else {
alert(4);
return (false);
}
}
}
}
Here is my entire html markup source. If you just look at the boldfaced lines below, you can see plainly where it is in the source code. I tried moving it out of the "td" and just an input tag right below the <form> tag, but the Telerik AjaxManager didn't like that even when I removed it from the UpdatedControls list under the Treeview:

The client ID of the hidden input is more complex that the one set in the server-side ID property. You can get the correct client ID by using serer-side expressions in your JS code in this way:
var hdnRecordSaved = document.getElementById("<%= hdnRecordSaved.ClientID %>");Have you tried this approach?

var hdnRecordSaved = document.getElementById("<%= hdnRecordSaved.ClientID %>");

}
else {

So what happens when you use the <%=%> expressions and you run this code? Do you receive any JavaScript errors?

There were some js errors on the page which was indirectly causing the issue.
