Asked On June 28, 2019 05:12 AM UTC

Hi all,

I am using ej2 Grid for represent my data. Accordingly I want to Strike current selected row with some highlighted color when clicking on a button (vice versa). After the strike of the particular row I need to capture that row using another button click. I'm currently deleting the row and capture deleted row by below code,

-- Deleting --

this.myGrid.deleteRecord("rowId", rowId);

-- Capturing --

beforeBatchSave(args: BeforeBatchSaveArgs) {
let changedRecords = args.batchChanges["changedRecords"];
let deletedRecords = args.batchChanges["deletedRecords"];

// Other logics goes here
}


Thank you.

Hi Isanka, 

Greetings from Syncfusion support. 

We can get the selected row data in the rowSelected event of Grid. 

[app.component.html] 

<ejs-grid [dataSource]='data' height='350' [allowPaging]=true (rowSelected)='rowSelected($event)'
        <e-columns> 

                 ---- 

        </e-columns> 
    </ejs-grid> 

----------------------------------------------------------------------------------------------------- 
[app.component.ts] 

export class AppComponent { 
    public data: Object[] = []; 

    ngOnInit(): void { 
        this.data = orderDetails; 
   
    rowSelected(args){ 
      console.log(args.data);  // you can get the selected record in the below argument 
   


We have prepared a simple sample in the following link.

Hi Thavasianand,

That is not the requirement I expected. Please see the example below,

https://cdn.extendoffice.com/images/stories/doc-excel/auto-strikethrough/doc-auto-strikethrough-5.png

Something like above example, I want to strike the selected row by button click and get the selected row data by another button click. Assume we have two separate buttons in the form. (If you don't have option to enable strike, use row color)

Thank you.

Your answer is most relevant to my requirement. But there are small improvements.
     1. I want to get striked records only.
     2. Another button for unstrike selected records.

Thank you very much.

Not working. I tried following code. Nothing striked but can see ''class="e-rowcell e-lastrowcell e-selectionbackground e-active strikeOut" class in the html source. I used direct Grid object. It is not the way, please let me know how to get grid by class name. (My view has more than one gird components)

@ViewChild('dataGrid') public dataGrid: Grid;

private findGridTdElement(strikeFlag, getStrikedFlag): any[] {

//var gridObj = document.getElementsByClassName('e-grid')[0]['ej2_instances'][0];
var strikedRows = [];

if (getStrikedFlag)
var rows = this.dataGrid.getRows();
else
var rows = this.dataGrid.getSelectedRows();

for (var i = 0; i < rows.length; i++) {
var tr = rows[i];
for (var j = 0; j < tr['childElementCount']; j++) {
if (tr.children[j].classList.contains('strikeOut') && strikeFlag) {
tr.children[j].classList.remove('strikeOut'); // Remove the strike row
}
else if (getStrikedFlag) {
if (tr.children[j].classList.contains('strikeOut')) {
strikedRows.push(this.dataGrid.currentViewData[i]); // Get the strike row detail
break;
}
else
break;
}
else if (!strikeFlag)
tr.children[j].classList.add('strikeOut'); // Enable strike row for selected record
}
}

this.dataGrid.dataBind();
return strikedRows;
}

Hi Isanka, 
 
Query 1: Nothing strike but can seestrikeOut" class in the html source 
 
We suspect that you may not add the CSS style for strikeout in the HTML page. So, please ensure on your end for the CSS style. 
 
 
<style>  
  
  .e-grid .strikeOut {  
  
    text-decoration: line-through;  
  
  }  
 
</style>

Hi Thavasianand,

I apologize for my fault. Now working perfectly. I have another queries to ask. In my gird, has checkbox column which is used as ng-template, 

<ng-template #gridCheckBoxTemplate let-data>
<ejs-checkbox [disabled]='apprColumnDisabled' [checked]='data.approval'
(change)="apprCheckBoxChanged($event, data)">
</ejs-checkbox>
</ng-template>

Query 1 :- In my scenario that striked record will change to non editable row. It can be done using 'CellEdit' event finding particular row and set to 'cancel = true'. But in the checkbox column, It can not be done. I want to know the way of doing the non editalbe to that checkbox cell.

Query 2 :- When we using the strike method to display as record has deleted that 'Update' tool bar button won't active (Because no changes has been done). I want to enable that 'Update' button.

Note: I'm using Batch Edit mode in the gird.

Highly appreciate your support.
Thank you.

Hi Neo, 

Query 1 : I want to know the way of doing the non editalbe to that checkbox cell. 
We have analyzed your query. Based on your requirement, you can disable editing for a particular column, by specifying columns.allowEditing to false. Please refer the code below, 

 
            <e-column width='120' [allowEditing]='false' textAlign='Right'></e-column> 
 

Documentation :  
 
Query 2 : I want to enable that 'Update' button. 
To enable the ‘Update’ button, we suggest you to remove the “e-overlay” class from that div element. In the below code, we have enabled the ‘Update’ button in a button click. We suggest you to use the same codes to enable the ‘Update’ button whenever you needed. Please refer the code below, 

 
       <button (click)="click()">Enable Update</button> 
 
click(args){ 
  this.grid.toolbarModule.element.querySelector("div[title|='Update']").classList.remove("e-overlay") 
} 
 
 
Please get back to us if you need further assistance. 

Regards, 
Thavasianand S.
