Show Hidden fields on Edit Dialog

[Danyelle]

 I have tried to follow your example in the guide and when I put the ActionBecgin part in my grid it returns a blank page with this error in the javascript browser.

Here is my code:

<div class="inventoryGrid">

    @Html.EJS().Grid("InventoryGrid").DataSource(DataManager => { DataManager.Json(@Model.Inventory.ToArray()).InsertUrl("/Home/AddInventoryItem").UpdateUrl("/Home/UpdateInventoryItem").Adaptor("RemoteSaveAdaptor"); }).AllowFiltering(true).AllowSorting(true).ActionBegin("actionBegin").ActionComplete("actionComplete")Columns(col =>

    {

    col.Field("InventoryID").HeaderText("Id").IsPrimaryKey(true).IsIdentity(true).AllowEditing(false).Width("40").Add();

    col.Field("HECNumber").HeaderText("HEC Number").Width("50").Visible(false).Add();

   

    }).AllowPaging(true).FilterSettings(filter => filter.Columns(filterColumns)).SortSettings(sort => sort.Columns(sortColumns)).PageSettings(page => page.PageSize(15)).EditSettings(edit => { edit.AllowAdding(true).AllowEditing(true).AllowDeleting(true).Mode(Syncfusion.EJ2.Grids.EditMode.Dialog); }).Toolbar(new List<string>() { "Add", "Edit" }).Render()

</div>

@Html.EJS().ScriptManager()

function actionBegin(args) {

        if ((args.requestType === 'beginEdit' || args.requestType === 'add')) {

            for (var i = 0; i < this.columns.length; i++) {

               if (this.columns[i].field == "HEC Number") {

                   this.columns[i].visible = true;

               }

              

            }

        }

    }

    function actionComplete(args) {

        if (args.requestType === 'save') {

            for (var i = 0; i < this.columns.length; i++) {

                if (this.columns[i].field == "HEC Number") {

                    this.columns[i].visible = false;

                }

               

                }

        }

    }

</script>

Hi Danyelle 

Greetings from Syncfusion support 

Based on your query we have prepared a sample using your code example and we are able to reproduce the reported issue at our end. To resolve the mentioned issue we suggest to add the ScriptManager at the bottom of the page. Please refer the below code example for your reference 

Code Example:   

@Html.EJS().Grid("RemoteSaveAdaptor").DataSource(dataManager => { dataManager.Json(@Model.orderData.ToArray()).InsertUrl("/Home/Insert").RemoveUrl("/Home/Delete").UpdateUrl("/Home/Update").Adaptor("RemoteSaveAdaptor"); }).Columns(col => 

{ 

    col.Field("OrderID").HeaderText("Order ID").IsPrimaryKey(true).Width("30%").Add(); 

    col.Field("EmployeeID").HeaderText("Employee ID").Width("150").Add(); 

    col.Field("CustomerID").HeaderText("CustomerID").Width("70").Visible(false).Add(); 

}).AllowPaging().ActionBegin("actionBegin").ActionComplete("actionComplete").AllowSorting(true).Toolbar(new List<string>() { "Add", "Edit", "Delete", "Update", "Cancel" }).EditSettings(edit => { edit.AllowAdding(true).AllowEditing(true).AllowDeleting(true).Mode(Syncfusion.EJ2.Grids.EditMode.Dialog); }).Render() 

<script> 

  function actionBegin(args) { 

    if ((args.requestType === 'beginEdit' || args.requestType === 'add')) { 

      for (var i = 0; i < this.columns.length; i++) { 

        if (this.columns[i].field == "CustomerID") { 

          this.columns[i].visible = true; 

        } 

      } 

    } 

  } 

  function actionComplete(args) { 

    if (args.requestType === 'save') { 

      for (var i = 0; i < this.columns.length; i++) { 

        if (this.columns[i].field == "CustomerID") { 

          this.columns[i].visible = false; 

        } 

      } 

    } 

  } 

</script>
