Binary Data in Data Grid :: C#

[Guest]

Hello

Given an array of binary data stored in an ArrayList container, do you associate the container as a datasource in a Data Grid control

private ArrayList xList = new ArrayList()

// Arbitrarily add 64 integers into containe

for (int i = 0; i < 64; ++i
this.xList.Add(i)

// Assuming Data Grid was created via wizar
thisTheDataGrid.DataSource = this.xList
thisTheDataGrid.Refresh()

The example above compiles okay. However, nothing shows up in the data grid. All you would see is 64 empty rows and no columns

Do you need to set a specific property to show arbitrary data in the grid

Thanks

The DataGrid needs a publicly accessible property so that it knows what to
pull for its columns. Try this:

private void Form1_Load(object sender, System.EventArgs e)
{
ArrayList xList = new ArrayList();

// Arbitrarily add 64 integers into container

for (int i = 0; i < 64; ++i)
xList.Add(new IntBox(i));

// Assuming Data Grid was created via wizard
dataGrid1.DataSource = xList;
}

public class IntBox
{
public IntBox(int val)
{
this.val = val;
}

public int Val
{
get
{
return val;
}
set
{
val = value;
}
}

private int val;
}

Okay. Thanks

I saw some examples on Data Grid and class properties. In your example, I believe the Data Grid will name the column "Val" as it is the property name
