[Solved] RadConfirm on OnTabselecting Issue

[vinod chandran]

function OnClientTabSelecting(sender, eventArgs) {
var tab = eventArgs.get_tab();
var navigateUrl = tab.get_navigateUrl();
if (navigateUrl && navigateUrl != "#" && dataChangeField.value == "true") {
var proceed = tabConfirm(Click OK to proceed or Cancel to stay on current page.',eventArgs, 330, 100, '', "Change");
if (!proceed) {
eventArgs.set_cancel(true);
}
else {
eventArgs.set_cancel(false);
dataChangeField.value = "false";
}
}

window.tabConfirm = function(text, ev, oWidth, oHeight, callerObj, oTitle) {
var callerObj = ev._tab._linkElement;
if (callerObj) {
//Show the confirm, then when it is closing, if returned value was true, automatically call the caller's click method again.
var callBackFn = function(arg) {
if (arg) {
callerObj["onclick"] = "";
if (callerObj.click) callerObj.click(); //Works fine every time in IE, but does not work for links in Moz
else if (callerObj.tagName == "A") //We assume it is a link button!
{
try {
eval(callerObj.href)
}
catch (e) { }
}
}
}
radconfirm(text, callBackFn, oWidth, oHeight, callerObj, oTitle);
}
return false;
}

The requirement is to show a rad confirm window on tab change event. When user clicks OK he/she will be navigated to the clicked tab, on cancel user will remain on current tab itself. The issue is here is radConfirm() is not returning true properly - in OnClientTabSelecting event I am checking whether radConfirm result is true or false and calling set_cancel() method. I am unable to capture the OK button click and set the value here. Would appreciate any inputs on this - this is urgent.

Thanks,
Aneesh

Hi Aneesh,

I tried another approach to accomplish the scenario. Have a look at the code that I tried for displaying RadConfirm on selecting the tab.

JavaScript:

<script type="text/javascript">
    var tab, check = false;
    function OnClientTabSelecting(sender, args) {
        tab = args.get_tab();
        if (tab.get_text() == "ParentTab2" && !check) {  // Check for your condition and another bool value check
            radconfirm("Hi", callBackFn, 500, 100, "", "");
            args.set_cancel(true);   // cancel the tab selection
        }
        if (check) {
            check = false;
        }
    }
    function callBackFn(arg) {
        if (arg) {
            var tabStrip = $find("<%= RadTabStrip1.ClientID %>");
            check = true;
            tab.select(true); // explicitly selecting the tab
        }
    }
</script>

function callBackFn(arg) {
        if (arg) {
            var tabStrip = $find("<%= RadTabStrip1.ClientID %>");
            check = true;
            tab.select(true); // explicitly selecting the tab
        }
    }

Thanks for your inputs. tab.select(true) doesn't select the tab. However, when make it tab.select() or tab.select(false), it selects the first tab and doesn't display the PageView content. I am using nested tabs and navigate url for each tab.

Hello Aneesh Pulukkul,

Please use the click() method instead, i.e.

tab.click();

I tried that - same problem persists. That is, the tab strip is not visible now.  I think the click action works but due to some other reason, the tab strip is going off the page.

Hi Aneesh Pulukkul,

I think it will be best if you can open a support ticket and send us a simple running project (incl. CSS, images, skins, DB backup if needed and so on) demonstrating the problem (and step-by-step instructions on doing so). In that way we can reproduce and pinpoint the problems you're facing on our side, understand the logic of your application and provide a solution.

Sincerely yours,
