How to obtain the data of the nested grid when clicking on the edit button?

[NovatoParticipant]

Hi, I have a main grid with a nested grid like in your demo. I am working with dynamic columns and within my main grid I have a button type column called Edit.

How can I get the data from the nested grid to show them in the textbox of my modal?

This is my code.

Thank you very much for your help.

function obtener_datos() {

    var persona = $("[id*=ddlPersona]").val();
    var Sucursal = "";
 
    if (persona != 0) {
       
        var valores;
        var datafields = new Array();
        var columns = new Array();
        var columnsArray = [];
      
        $.ajax({
            type: "POST",
            dataType: "json",
            url: "frmPersona.aspx/Intervalo",
            contentType: "application/json; charset=utf-8",
            data: '{id_persona:"' + persona + '",Sucursal:"' + Sucursal + '"}',
            async: false,

            success: function(data) {

                if (data != '') {
          
                    valores = JSON.parse(valores[0]);

                    for (var i in valores[0]) {
                        datafields.push({ name: i, type: 'string' });
                        columns.push({ text: i, datafield: i, filtercondition: 'CONTAINS', align: 'center', minwidth: 100 });
                       
                    }

                    for (var j = 1; j < columns.length; j++) {
                        columnsArray.push(columns[j]);
                      
                    }

                }

                var gridSource =

                    success: function(data, status, xhr) {                                                        
                    commit(true);

Hello Novato,

First for all, please, take a note that a sub-grid is initialized when you expand it for a first time. You will not be able to take a nested grid data if it is not first expanded.

You could review the example code below. When a row is expanded all nested grid rows are logged in the console. I hope this would be helpful.

Hi Todor.

This example works great for me but I have encountered a problem and that is that by filtering through the textbox using the showfilterrow property on my main grid I can no longer obtain the data as you mention me.

Any idea how to fix this?

Thank you.

[NovatoParticipant]

Hi, thanks. I have been able to solve my problem.
