This might help you How can I adjust the columns horizontally so that the data fills the entire DataGridView and leaves no blank spaces to the left or right of the data? , try this :
code :
dataGridView1.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill

code :
dataGridView1.Columns[dataGridView1.Columns.Count - 1].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

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)

        if (e.ColumnIndex > 0)

        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;

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


    public class MyItemData
        public string ItemCode { get; set; }
        public string BarCode { get; set; }

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();


        return newItem;

public class MyDBLayer
    public DataSet ReturnItemData(string itemCode)
        DataSet myDataSet;
        //Query database and set dataSet
        return myDataSet;
DataGridView size is out of splitContainer panel even the Dock property is Fill

DataGridView size is out of splitContainer panel even the Dock property is Fill

seems to work fine There are a SplitContainer and couple of DataViewGrids. In Designer I docked DataViewGrids to Panel1 and Panel2 of SplitContainer respectively. So, in designer everithing seems to be OK. But when I start the program, the DataGridView seems like it's docked to the main form, because the size of the Grid is the main Form size. I use the Grids with bindings to DataSet. When I try to use not binded blanc Grids, everithing is ok. The grids size matches the splitContainer Panels sizes. That drives me insane:( , ok you should set dockstyle of grid to fill the panel as this
