Hi experts , I am using server side filter on my grid . I am not using JSP wrappers it is just  normal kendo grid connected to servlet where to obtain data. I am giving the user to filter any coulmns as he wishes on my grid. what I am looking for is I need to translate the JSon filter made by the user to sql expression so I can use it to retreive data from the database. my Json filter representation is as below 

{"logic":"and","filters":[{"field":"name","operator":"startswith","value":"ji"},{"field":"name","operator":"contains","value":"m"},{"field":"price","operator":"eq","value":"55"}]}

it is too much difficlut for me to translate it to sql expression . I have searched a lot , all I found on ASP not the JSP 

please help me at least with the method/function to convert the json correctly as it is made by user on grid.

Dear Support Team ,

  I have simple grid where I am getting data from Java Controller in JSON format ( all data getting at glance no sever hits for pages ). The Gird shows DATA but no page buttons are displayed to do pagination. I have also included buttoncount=5 but no success. But the grid shows the some data on the screen as per settings pagesize=5. There are total 12 records in the JSON but its shows only 5.  We need your valuable support to go ahead further development. Thanks in advance...!

WE NEED YOUR SUPPORT TO RESOLVE THIS ISSUE. THANKS IN ADVANCE...!

Thanks
Shridhar

I am trying to reload contents of tabs on every click on tabs. How can I achieve this.. As I am trying to access current object in select event by using following code, but it gives error of null object.

 <kendo:tabStrip name="tabstrip2" select="onSelect">
        <kendo:tabStrip-items >
                    <kendo:tabStrip-item  text="Bid Screen" selected="true"  contentUrl="${ajaxContent1}"></kendo:tabStrip-item>

                    <kendo:tabStrip-item text="Clients" contentUrl="${ajaxContent2}"></kendo:tabStrip-item>
            <kendo:tabStrip-item text="Reports" contentUrl="${ajaxContent3}"></kendo:tabStrip-item>
                 <kendo:tabStrip-item text="Downloads" contentUrl="${ajaxContent4}"></kendo:tabStrip-item>
                
        </kendo:tabStrip-items>
             
    </kendo:tabStrip>

 function onSelect (e) {
     var tabStrip = $("#tabStrip2").data("kendoTabStrip");
  alert(tabStrip);//shows null
                  
    }

I am not using duplicate js files ,If I remove js files it does not show tabs.

thanks

    {

        System.out.println("In controller - read method");
        List<WorkRequest> databaseList = listCandidate.retrieveData(data);
        System.out.println("list size:" +databaseList.size());
        return databaseList;
    }​

Symptoms

Loading kendo.all.min.js file in IE 8 results in multiple JavaScript errors.

Typically the error message will be "Object doesn't support this property or method" and will be caused by a call to map, forEach or bind.

Root Cause

The errors are due to the inclusion of the Kendo UI Spreadsheet​ which requires IE9 and later.

It was nevertheless bundled in kendo.all without the necessary run-time checks.

Mitigation

• Use a custom bundle that does not include the Spreadsheet widget
• Load an ES5 Polyfill, for example es5-shim, before kendo.all.min.js:

Solution

A permanent fix will be included in the next internal build, version 2015.3.1002, due for release on 2 Oct 2015.

Future Service Packs and official releases will be free of this defect as well.

Apologies for the caused inconvenience.​

Hi,

   I have a kendo jsp tree view defined in the below format. Tree view works without any issue. It looks like Kendo library is throwing JSP exception while processing - JspException: The <kendo:dataSource> tag should be nested in a <kendo:dataSource-schema-hierarchical-model> tag

<kendo:treeView name="formsNav" select="onSelect">
        <kendo:dataSource data="${​tree view data sent from server side}" />
 </kendo:treeView>​

Can you please help resolve this issue?

Thanks!

While creating tabstrip, tabs are configured to load dynamically through Ajax loading.

Now when we click on the tab(one) manually it is loading contents properly via Ajax but when some other tab(two) is visible and we want to select tab(one) on click of a button on tab(two) its not loading via Ajax and an empty content pane is shown under the tab(one).

we created tabs via below code

            <div class="wrapper" style="width: 100%;">
                <kendo:tabStrip name="homeTabstrip" show="onShow" select="onSelect" activate="onActivate" contentLoad="onContentLoad">
                    <kendo:tabStrip-items>
                        <kendo:tabStrip-item text="Assessment"    contentUrl="${assessmentTab}"></kendo:tabStrip-item>
                        <kendo:tabStrip-item text="Search Result" contentUrl="${searchTab}"></kendo:tabStrip-item>
                        <kendo:tabStrip-item text="Administration"  selected="true" contentUrl="${adminTab}"></kendo:tabStrip-item>
                    </kendo:tabStrip-items>
                </kendo:tabStrip>
            </div>

Now to select tab(one) while sitting on tab(two) we use below code:

    var tabstrip = $("#homeTabstrip").kendoTabStrip().data("kendoTabStrip");

tabstrip.select(1);
​

In the following example , there are the following problems:

1. The delete button does not ask for confirmation. PUT generates rather than a DELETE.
2. When updating generates a PUT rather than POST .
3. If I remove <kendo:dataSource-transport-create> nothing works .​ Only GET (READ)
4. <kendo:dataSource-transport-parameterMap>​ I've also moved from after the last <kendo:dataSource-transport-...> site and has the same behavior.

I 'm testing with the trial version .

Thank you for any help.​

Hi All,

 I'm completely new to this framework and I have an issue with the paging inside GRID. I don't know what is happening but the GRID return all the records instead of what have been set on pageSize. Thanks in advance.

 This is my GRID code:

 <c:url value="${api_r}"  var="transportReadUrl" />                
                <kendo:grid name="grid" pageable="true" height="690px" sortable="true" filterable="false" groupable="false">
                    <kendo:grid-scrollable/>
                    <kendo:grid-columns>
                        <kendo:grid-column title="${codefieldtext}" field="${codefield}" width="100px" />
                        <kendo:grid-column title="${codenametext}" field="${codename}" width="100px" />                
                    </kendo:grid-columns>
                    <kendo:dataSource pageSize="20" serverPaging="true" serverSorting="true" serverFiltering="true" serverGrouping="true">
                        <kendo:dataSource-transport>            
                            <kendo:dataSource-transport-read url="${transportReadUrl}" type="POST" contentType="application/json"/>  
                            <kendo:dataSource-transport-parameterMap>
                                <script>
                                    function(options){return JSON.stringify(options);}
                                </script>   
                            </kendo:dataSource-transport-parameterMap>            
                        </kendo:dataSource-transport>
                        <kendo:dataSource-schema data="Results" total="Total" groups="Results">
                            <kendo:dataSource-schema-model>
                                <kendo:dataSource-schema-model-fields>                            
                                    <kendo:dataSource-schema-model-field name="${codefield}" type="string" />
