Synfusion controls within content rendered within a Synfusion Tab control

[Charles Southey]

Hi - I'm using the tab control with content that gets rendered from CSHTML partial views. All works fine, except that for any content that contains other SyncFusion controls the script block created by @Html.EJS().ScriptManager() is causing problems. If I render it within the partial view it causes an error (Invalid Token) - if I leave the @Html.EJS().ScriptManager() off and rely on the one in _Layout it won't realise it needs to render code for those controls within the partial view.

I've tried manipulating the rendered partial content using Regex to extract the script block and add it later - but I can't get it to consistently run at the right time.

What is your recommendation w.r.t. rendering content within a Tab control that contains other Syncfusion controls?

Hi Charles, 

 

Thank you for using Syncfusion products. 

 

Query1:” What is your recommendation w.r.t. rendering content within a Tab control that contains other Syncfusion controls?” 

 

The recommended approach to load content in Tab is to use AJAX call that loads the content in the Tab on demand in the Created and Selected event of Tab. Kindly refer to the following code snippet.   

  

  

@Html.EJS().Tab("MainTab").Created("tabCreated").Selected("tabSelected").Render()  

  

<script>  

    var loaded = false;  

    function tabCreated(e) { // created event to create the Tab items and data for first tab   

        var tabObj = document.getElementById("MainTab").ej2_instances[0];  

        var ajax = new ej.base.Ajax('@Url.Action("PartialView1", "Home")', 'GET', true);  

        ajax.send().then();  

        ajax.onSuccess = function (data) {  

            tabObj.addTab([{ header: { 'text': 'Grid1' }, "content": "<div id='GridOrder1'></div>" }],0);  

            tabObj.addTab([{ header: { 'text': 'Grid2' }, "content": "<div id='GridOrder2'></div>" }],1);  

            $("#GridOrder1").html(data);  

        }   

    }  

    function tabSelected(e) { // selected event to load data dynamically based on the selection of the tab item   

        if(e.selectedIndex != 0 && !loaded){  

            var tabObj = document.getElementById("MainTab").ej2_instances[0];  

            var ajax = new ej.base.Ajax('@Url.Action("PartialView2", "Home")', 'GET', true);  

            ajax.send().then();  

            ajax.onSuccess = function (data) {                  

                $("#GridOrder2").html(data);   

                loaded = true;  

            }  

        }   

    }  

</script>  

  

In our example, we have created both the Header and content as dynamic. if you don’t want to set them as dynamic, then you can directly set the items in the same way we given in the example. 

 

We have attached the sample for your reference, please find the sample at the following link: http://www.syncfusion.com/downloads/support/directtrac/222473/ze/WebApplication2-753147216
