  4. Calculate total for row and refresh grid after insert command

Calculate total for row and refresh grid after insert command

Good afternoon gentleman,

I'm trying to calculate the total amount for each row, i have for each row the amount data and Unit price and i need to automatic calculate the total which I think is something like:

          rowTotal = (rowCant * rowUnitPrice) - rowDiscount;
          document.querySelector("#ConfiguracionPACGridImporte").value = rowTotal;

The thing is that I'm not sure how or where to trigger this action. 

Second question is, after I register a new record the grid is not refreshing itself, how can I auto refresh it after I click update button?


In advice, I give my thanks, You have a really good product and an Excellent support service!

Hi Javier, 
 
Thanks for contacting Syncfusion support. 
 
Query #1: I'm trying to calculate the total amount for each row, i have for each row the amount data and Unit price and i need to automatic calculate the total which I think is something like 
 
From your code, we found that you have tried to provide the calculated value to “Importe” column numericTextBox while changing the value in “cantidad” column. So, we suggest to bind the “input”  event to “cantidad” column input textbox and use that event to provide a calculated value to “Importe” column numericTextBox through the instance. Please refer the below code snippet, 
 
<ejs-grid id="Grid" allowPaging="true" actionComplete="actionComplete" toolbar="@(new List<string>() { "Add","Delete","Update", "Cancel" })"> 
    <e-data-manager url="/Home/UrlDatasource" insertUrl="/Home/Insert" updateUrl="/Home/Update" removeUrl="/Home/Remove" adaptor="UrlAdaptor"></e-data-manager> 
    <e-grid-editSettings allowAdding="true" allowEditing="true" allowDeleting="true" mode="Normal"></e-grid-editSettings> 
    <e-grid-columns> 
        <e-grid-column field="OrderID" headerText="Order ID" isPrimaryKey="true" width="100"></e-grid-column> 
        <e-grid-column field="Freight" headerText="Freight" format="C2" width="120"></e-grid-column> 
        <e-grid-column field="EmployeeID" headerText="Employee ID" editType="numericedit" format="C2" width="120"></e-grid-column> 
    </e-grid-columns> 
</ejs-grid> 
 
<script type="text/javascript"> 
    function actionComplete(args) { // Grid actionComplete event 
        if (args.requestType == "beginEdit") {  
            args.form.querySelector("#GridFreight").addEventListener("input", function (e) { // bind the input event to Freight column input textbox 
                var value = parseFloat(this.value); 
                value = value * 10; 
                var numericTextBox = args.form.querySelector("#GridEmployeeID").ej2_instances[0]; // numericTextBox instance 
                numericTextBox.value = value; // Change the numericTextBox value with calculated value through the instance 
            }) 
        } 
    } 
</script> 
 
In this code, we have bound the “input” event for Freight column input textbox by using the Grid actionComplete event. After that we have used this “input” event to change the EmployeeID column numericTextBox value. 
 
Query #2: Second question is, after I register a new record the grid is not refreshing itself, how can I auto refresh it after I click update button? 
 
By default, Grid will automatically refresh when we add the new record in Grid. But while using the remote data, we must need to return the newly added record from the controller to Grid. So, please ensure whether added record is properly returned or not. You can use browser network tab to ensure the controller returned value. 
 
For your convenience, we have prepared the sample with this both queries and you can find that sample from the below link, 
 
 
If we misunderstood your query, please share more details about requirement. This will help us to provide a better solution for your issue as early as possible.

Pavithra S. 
 


JA Javier A Aguilera July 1, 2019 08:34 PM UTC

Thank you very much for your fast answer, I really appreciate it. 

Unfortunately, I still havent reach the spected functionality (probably my bad), can you please help me out? What am I missing?


The points are still the same:
1) I need to calculate "Importe" with "Cantidad" and "ValorUnitario" (currently im trying to multiply by 10 for ease)
2) The I click Update button after typing all fields for a new record I need the grid to refresh its content (but still i cant get that to work)

In the second point, I just discover a difference between your example and mine, in mine i cannot reach actioncomplete alert of "save" when i click the button of Update....probable my error is in the controller action, but i dont get errors in the console while running this point.

In advance, thank you for your support

Hi Javier, 
 
Query #1:  I need to calculate "Importe" with "Cantidad" and "ValorUnitario" (currently im trying to multiply by 10 for ease) 
 
From you code we found that you want to update numericTextBox values in “ValorUnitario” and “Importe” columns based on the updated “Cantidad” column value. You can achieve this requirement like as below code snippet, 
 
function actionComplete(args) { // Grid actionComplete event 
        alert(args.requestType); 
        if (args.requestType == "beginEdit") { 
            args.form.querySelector("#ConfiguracionPACGridCantidad").addEventListener("input", function (e) { 
                var value = parseFloat(this.value); 
                value = value * 10; 
                var CantidadNumericTextBox = args.form.querySelector("#ConfiguracionPACGridImporte").ej2_instances[0]; 
                CantidadNumericTextBox.value = value; // Change the Importe numericTextBox value based on Cantidad 
                var UnitarioNumericTextBox = args.form.querySelector("#ConfiguracionPACGridValorUnitario").ej2_instances[0]; 
                UnitarioNumericTextBox.value = value; // Change the ValorUnitario numericTextBox value based on Cantidad 
            }) 
        } 
    } 
 
If you will face any issue while applying this solution, please share the issue details (like screenshot or video demonstration) to us  for further assistance. 
 
Query #2:  I just discover a difference between your example and mine, in mine i cannot reach actioncomplete alert of "save" when i click the button of Update…probable my error is in the controller action, but i dont get errors in the console while running this point. 
 
First we would like to inform that we could not understood this query properly. So, we suspect that you want to find the failed actions in Grid. You can use actionFailure event to achieve this requirement. You can get the issue details in this event arguments. If you need further assistance, then please share this event argument details and controller issue details to us. 
 
Documentation for actionFailure event, 
 
 
Regards, 
Pavithra S.
