I have a Datagrid that is being built dynamically from incoming data using the following:

TableData = JObject.Parse(File.ReadAllText(@"Datainfo.json"));

var listCols = new List<DataColumn>();

var rawData = new DataTable();

foreach (dynamic item in TableData.data)

{

    string columnName = item.Column;

    var column = new DataColumn(columnName);

    string DataType = item.DataType;

    if (DataType == "Int" )

    {

        column.DataType = Type.GetType("System.Int32");

    }

    else

    {

        column.DataType = Type.GetType("System.String");

    }

    column.Unique = false;

    column.AllowDBNull = true;

    column.AutoIncrement = false;

    listCols.Add(column);

    rawData.Columns.Add(column);

}

Then I am pushing it to the DataGrid like this:

    DataTable ETL = null;

    ETL = rawData;

    ETL.DefaultView.AllowEdit = true;

    DataGridView.DataContext = ETL;

I would like to add a StackPanel to each column that includes a TextBox for the Column Name, and a dropdown that has various datatypes in it. It would then have a Apply / Cancel option.

I have been trying to follow similar solutions for adding Expanders to Grids, but I can't figure out how to apply it to a DataGrid since it doesn't have a .Children() to .Add() to.

Is there a way to do what I am asking? I also tried to hide the header row and control the first two rows, but then when I tried loading up the header into a Int column, I get an error, so obviously that isn't a good idea.

If you are adding this to the column header than you must add it as a HeaderTemplate.
Lets say this is the XAML...

<Window x:Class="testtestz.MainWindow"

        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

        Title="MainWindow"

        xmlns:local="clr-namespace:testtestz"

        xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity">

    <Grid>

        <ListView>

            <ListView.View>

                <GridView x:Name="myGrid">

                    <GridViewColumn Header="Id"/>

                    <GridViewColumn Header="Name"/>

                    <GridViewColumn Header="Date"/>

                </GridView>

            </ListView.View>

        </ListView>

    </Grid>

</Window>

Then you would do this in the code behind...

using System;

using System.Windows;

using System.Windows.Controls;



namespace testtestz

{ 



    public partial class MainWindow : Window

    {

        public MainWindow()

        {

            InitializeComponent();

        }



        protected override void OnContentRendered(EventArgs e)

        {

            base.OnContentRendered(e);



            var cBox = new FrameworkElementFactory(typeof(ComboBox));



            myGrid.Columns[0].HeaderTemplate = new DataTemplate() { VisualTree = cBox };

        }

    }

}

This is just a showcase of how to do it. Of course you would have to play with some layout, sizes and simillar stuff to get it to a reasonable point but I hope it helps.
