To fix this issue When editing the columns, there is a property called AutoSizeMode. Im wondering why you are trying to handle it yourself. Just set all columns except the first one to AutoSizeMode = AllCells and then give your first column the width of 100px. Should do it shouldnt it?
Bonus: You can even set one of the columns to Fill in AutoSizeMode. Would look a bit better as your table is taking the full width.

Any of those help I am populating a DataGridView control on a Windows Form (C# 2.0 not WPF). , This trick works for me:
code :
grd.DataSource = DT;

//set autosize mode
grd.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
grd.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
grd.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

//datagrid has calculated it's widths so we can store them
for (int i = 0; i <= grd.Columns.Count - 1; i++) {
    //store autosized widths
    int colw = grd.Columns[i].Width;
    //remove autosizing
    grd.Columns[i].AutoSizeMode = DataGridViewAutoSizeColumnMode.None;
    //set width to calculated by autosize
    grd.Columns[i].Width = colw;
}

hope this fix your issue Set the ScrollBars property of DataGridView to None and use this code to set size of rows:
code :
foreach (DataGridViewRow row in dataGridView1.Rows)
{
    row.Height = (dataGridView1.ClientRectangle.Height - dataGridView1.ColumnHeadersHeight) / dataGridView1.Rows.Count;
}
private void dataGridView1_SizeChanged(object sender, EventArgs e)
{
    foreach (DataGridViewRow row in dataGridView1.Rows)
    {
        row.Height = (dataGridView1.ClientRectangle.Height - dataGridView1.ColumnHeadersHeight) / dataGridView1.Rows.Count;
    }
}

Hope this helps I use the following code to bind DataTable with DataGridView: , You can add them to your DataGridView. Like this:
code :
var checkBox = new DataGridViewCheckBoxColumn
{
    Name = "checkBox",
    HeaderText = @"checkBox",
    Width = 70
};
//Set other properties...
dataGridView1.Columns.Add(checkBox);
DataGridViewImageColumn image = new DataGridViewImageColumn();
//....
dataGridView1.DataSource = dt;
var checkBox = new DataGridViewCheckBoxColumn
{
    Name = "checkBox",
    HeaderText = @"checkBox",
    Width = 70
};
//Set other properties...
dataGridView1.Columns.Insert(1, checkBox);
dt.Columns.Add(new DataColumn("checkBox", typeof(bool)));
dataGridView1.DataSource = dt;

it should still fix some issue You can use the CellValueChanged event of the data grid view control. Below is a simple example demonstrating the capture of the item code entered, passing this to a business layer which in turn calls a database layer and returns you a populated item for use on the grid.
code :
 private void Form1_Load(object sender, EventArgs e)
 {
       //Bind cell value changed event or set in designer.
       dgGridView.CellValueChanged += dgGridView_CellValueChanged;
 }

    private void dgGridView_CellValueChanged(object sender, DataGridViewCellEventArgs e)
    {
        if (e.RowIndex == -1)
            return;

        if (e.ColumnIndex > 0)
            return;

        var myBL = new MyBL();

        switch (e.ColumnIndex)
        {
            case 0: //Item Code Column
                var itemCodeEntered = dgGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Value.ToString();
                var itemData = myBL.GetItemData(itemCodeEntered);
                dgGridView.Rows[e.RowIndex].Cells[0].Value = itemData.ItemCode;
                dgGridView.Rows[e.RowIndex].Cells[1].Value = itemData.BarCode;
                break;

            case 1: //Bar code column
                // Do other stuff here.
                break;

            //etc...
        }

    }
    public class MyItemData
    {
        public string ItemCode { get; set; }
        public string BarCode { get; set; }
        //etc...
    }

public class MyBL
{
    public MyItemData GetItemData(string itemCode)
    {
        var myDL = new MyDBLayer();
        var itemDataSet = myDL.ReturnItemData(itemCode);

        var newItem = new MyItemData();
        newItem.ItemCode = itemCode;
        newItem.BarCode = itemDataSet.Tables[0].Rows[0]["BarCode"].ToString();

        //etc...

        return newItem;
    }
}


public class MyDBLayer
{
    public DataSet ReturnItemData(string itemCode)
    {
        DataSet myDataSet;
        //Query database and set dataSet
        return myDataSet;
    }
}
How to resize the Image control to fill horizontally and vertically resize the same amount

How to resize the Image control to fill horizontally and vertically resize the same amount

Hope this helps As your requirement , do you mean you want the Image control has the same value of WidthRequest and HeightRequest. And you can resize it?
You don't need to override the image control, just use data binding to bind the WidthRequest and HeightRequest to the same value.
