Hi everybody!

I have to fill a column in a datagridview with a default value, therefore I have defined a custom column & celltype:

public class ColumnaCalendario : DataGridViewColumn
{
public ColumnaCalendario(): base(new CeldaCalendario())
{
}
}

public class CeldaCalendario : DataGridViewTextBoxCell
{
public CeldaCalendario() : base()
{
}

public override object DefaultNewRowValue
{
get
{
return DateTime.Today;
}
}
}

I have added a column of that custom type to my DataGridView, and new rows are supplied with a correct default value.
However, whenever I click on the new row, the default value dissapears and doesn't come back.

Any Ideas?

Thanks in advance.

There isn't more to explain.

That code for the custom column, and a grid with that custom column inside it.

Hi,

Sorry, I can’t reproduce.

I use the following code.

public partial class Form1 : Form

{

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

ColumnaCalendario cc = new ColumnaCalendario();

cc.Name = "test";

cc.HeaderText = "test";

dataGridView1.Columns.Insert(0,cc);

}

private void button1_Click(object sender, EventArgs e)

{

Console.WriteLine(dataGridView1.Rows[0].Cells[0].Value.ToString());

}

}

// copy your code

public class ColumnaCalendario : DataGridViewColumn

{

public ColumnaCalendario()

: base(new CeldaCalendario())

{

}

}

public class CeldaCalendario : DataGridViewTextBoxCell

{

public CeldaCalendario()

: base()

{

}

public override object DefaultNewRowValue

{

get

{

return DateTime.Today;

}

}

}

And When I click the cell:

I think I must miss something. Could you please provide more details or make a demo project for us to test? Please upload your demo project to some server and offer us the URL.
