Error when modifying dynamically generated columns

[TaeWook Kang]

Hi :)

An error occurs when modifying dynamically generated columns in the grid.

 The [Work Master] and [Material Master] columns created with HTML tags are modified normally. However, dynamically generated columns [Total Qty.], [OPP-101-001], [OPP-101-002], and [OPP-101-003] have errors when double-clicked for Edit.

Please refer to the attached video with an error and the cshtml, controller, and model files on the page.

I would appreciate it if you could solve it as soon as possible.

Hi Taewook,

Thanks for contacting Syncfusion support.

You can resolve the reported problem by creating a column with null Uid in the controller side. The refreshColumns method binds the respective uid value to that column. Find the below code and sample for your reference.

 

[HomeController.cs]

        [HttpPost]

        public IActionResult GridHeaderAndDataBinding(string sJobNo, string sMtoSeq)

        {

 

                List<GridColumn> headerList = new List<GridColumn>();

                GridColumn workTotal = new GridColumn

                {

                    Field = "WORK_TOTAL",

                    HeaderText = "Work",

                    HeaderTextAlign = TextAlign.Center,

                    TextAlign = TextAlign.Right,

                    Width = "100",

                    Uid = null

                };

 

                GridColumn matlTotal = new GridColumn

                {

                    Field = "MATL_TOTAL",

                    HeaderText = "Material",

                    HeaderTextAlign = TextAlign.Center,

                    TextAlign = TextAlign.Right,

                    Width = "100",

                    Uid = null

                };

 

                List<GridColumn> totalColumns = new List<GridColumn>();

                totalColumns.Add(workTotal);

                totalColumns.Add(matlTotal);

 

                GridColumn totalQty = new GridColumn

                {

                    HeaderText = "Total Qty.",

                    HeaderTextAlign = TextAlign.Center,

                    TextAlign = TextAlign.Center,

                    Columns = totalColumns

                };

 

                headerList.Add(totalQty);

 

                for (int i = 0; i < 1; i++)

                {

                    GridColumn workQtyCol = new GridColumn

                    {

                        Field = $"WORK_QTY{i}",

                        HeaderText = "W.Qty.",

                        HeaderTextAlign = TextAlign.Center,

                        TextAlign = TextAlign.Right,

                        Width = "100",

                        Uid = null

                    };

 

                    GridColumn matlQtyCol = new GridColumn

                    {

                        Field = $"MATL_QTY{i}",

                        HeaderText = "M.Qty.",

                        HeaderTextAlign = TextAlign.Center,

                        TextAlign = TextAlign.Right,

                        Width = "100",

                        Uid = null

                    };

 

                    List<GridColumn> QtyColumns = new List<GridColumn>();

                    QtyColumns.Add(workQtyCol);

                    QtyColumns.Add(matlQtyCol);

 

                    GridColumn parentCol = new GridColumn

                    {

                        HeaderText = "Dynamic",

                        HeaderTextAlign = TextAlign.Center,

                        TextAlign = TextAlign.Center,

                        Columns = QtyColumns

                    };

 

                    headerList.Add(parentCol);

                }

                List<object> returnList = new List<object>();

                returnList.Add(headerList);

                returnList.Add(BigData.GetAllRecords());

                return Json(returnList);

        }
