Asked On May 14, 2019 07:36 AM UTC


I am implementing EJS syncfusion grid server side pagination and search by web api adaptor as i mentioned below screen shot. 

When click "Edit" icon or "Row double click" it will go to Edit page. When submit it will be back to grid. Here i want to retain the "Double click row should be selected" and "Page", "search" also retain. Please help me to solve this. 

I am using asp.net core 

Here is my server side code for Paging and Searching,

Hi Mani, 
Greetings from the Syncfusion support, 
As we have validated your code example and created a sample with your requirements. In below code example, you can retain the Search, Paging and Selection of EJ2 Grid when double click on the EJ2 Grid row using the “dataBound”, “recordDoubleClick” events in which you can save the Grid  state into local storage and then reset it while returning to the Grid. Please refer the code example and sample for more information. 
<ejs-grid id="Grid" allowPaging="true" dataBound="onDataBound" recordDoubleClick="ejsGridDoubleClick" toolbar="@(new List<string>() {"Search" })"> 
    <e-data-manager id="myData" url="/api/Orders" adaptor="WebApiAdaptor" crossDomain="true"></e-data-manager> 
        <e-grid-column field="OrderID" headerText="Order ID" isPrimaryKey="true" textAlign="Right" width="120"></e-grid-column> 
        <e-grid-column field="CustomerID" headerText="Customer Name" width="150"></e-grid-column> 
        <e-grid-column field="ShipCity" headerText="Ship City" width="170"></e-grid-column> 
        <e-grid-column field="ShipCountry" headerText="Ship Country" template="<a>${ShipCountry}</a>" width="150"></e-grid-column> 
    var selectIndx; 
    var flag = false; 
    function onDataBound(args) { 
        // Get the EJ2 Grid currentPageIndex, selection index and search string value from local storage 
         // you can also add conditions based on your requirement here 
        var currentPageIndex = parseInt(window.localStorage.getItem("pageIndex"), 10); 
        var selectedRowIndex = parseInt(window.localStorage.getItem("selectIndex"), 10); 
        var searchString = window.localStorage.getItem("searchString"); 
        if ((selectedRowIndex && currentPageIndex == 1) || flag) { 
            selectIndx = selectedRowIndex ? selectedRowIndex : selectIndx; 
            window.localStorage.removeItem("selectIndex");   // once set the selection index to grid then, we have reset the local storage            
        if (currentPageIndex) { 
            this.pageSettings.currentPage = currentPageIndex; 
            flag = true; 
        if (searchString) { 
    function ejsGridDoubleClick(args) {   
       // Here, we have set the EJ2 Grid currentPageIndex, selection index and search string value to localstorage       
        window.localStorage.setItem("pageIndex", this.pageSettings.currentPage ); 
        window.localStorage.setItem("selectIndex", args.rowIndex);  
        window.localStorage.setItem("searchString", this.searchSettings.properties.key);  
        if (window.location.rel='nofollow' href.split("Home").length > 1) { 
            window.location.rel='nofollow' href = window.location.rel='nofollow' href.split("Home")[0] + "Home" + "/About" 
        } else { 
            window.location.rel='nofollow' href = "Home/About" 
Please get back to us, if you any further assistance.
