    I have a situation where I have a TreeNode that the user is associating data (via the OnNodeClick event) with other controls on the page. Meaning, if the user clicks on node1 and fills in data (to the right of the treeview), but doesn't save the data, then tries to click on node2, before they get to that node, I want to prompt them to Save their data first for node1 before moving to node2.

    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 tried this, but it's not working....

    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.

    OK, I know I have a valid solution, but the js is telling me that the value in the hdnRecordSaved variable has no value!
    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.

    <

     

    asp:Panel ID="pnlMapFields" runat="server" ScrollBars="Both" Height="430px">

     

     

    <telerik:RadTreeView ID="RadTreeView1" runat="server" DataTextField="Description"

     

     

    DataFieldParentID="MapFieldparentID" DataFieldID="MapFieldID" DataValueField="MapFieldID"

     

     

    OnClientNodeClicking="onNodeClicking" CausesValidation="false" OnNodeClick="RadTreeView1_OnNodeClick">

     

     

    </telerik:RadTreeView>

     

     

    </asp:Panel>

     


    <table id="Table6" width="100%" runat="server" cellpadding="1" cellspacing="1" border="0">
                                        <tr>
                                            <td class="td_AEVNoBold" align="center">
                                                <asp:HiddenField ID="hdnRecordSaved" runat="server" />
                                            </td>
                                        </tr>
                                    </table>

    Note that the below bolded html has no trouble with the fieldnames which is in the same function.
    <table id="Table7" width="100%" runat="server" cellpadding="1" cellspacing="1">
                                                    <tr valign="top">
                                                        <td class="td_AEVNoBold" width="15%">
                                                            Mapping Field Name:
                                                        </td>
                                                        <td class="td_AEVNoBold">
                                                            <asp:Label ID="MappingField" runat="server" Font-Bold="true"></asp:Label>&nbsp (
                                                            <asp:Label ID="mapValue" runat="server" Font-Bold="true" ForeColor="blue"></asp:Label>
                                                            &nbsp;)
                                                        </td>
                                                    </tr>
                                                    </table>

    <asp:Label ID="FieldName" runat="server" Font-Bold="true" ForeColor="Blue"></asp:Label>

    var

     

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

     

     

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

     

     

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

     

    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); // gives correct value
                //alert(hdnRecordSaved.innerText); only valid if I make this a label, but its visiibility would be invisisble.
                //alert(hdnRecordSaved.value); gives no 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);
                        }
                    }
                }
            }

    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:

    Hi William Yeager,

    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?

    Simon, what I needed to do was the following... Setting up the variable on a one time basis at the bottom of the page wasn't enough for some reason. I had to get them again as follows. I handled the hdnRecordResponse variable in the code behind whether or not to process the next node that was clicked or to stay at the current node.

            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();

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

                if (hdnRecordSaved.value == "0") {
                    if ((startPosition.value != "") || (endPosition.value != "")) {
                        var hdnRecordResponse = document.getElementById("<%= hdnRecordResponse.ClientID %>");
                        if (confirm("Are you sure you want to navigate away from this tree node or submit functionality without saving your data?")) {
                            hdnRecordResponse.value = "1";
                            return (true);
                        }
                        else {
                            hdnRecordResponse.value = "0";
                            return (false);
                        }
                    }
                }
            }

    Hi William Yeager,

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

    All the best,

    Simon, this has been resolved....

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