I am adding a new row to the datagrid dynamically but if i use the Count property of Item it is not

[Praveen Balanagendra via .NET 247]

here is the source code

private void AddRow()
{
TableCell tc = new TableCell();
tc.Controls.Add(new LiteralControl("NewRow"));

DataGridItem di = new DataGridItem(DataGrid1.Items.Count+1,DataGrid1.Items.Count+1,ListItemType.Item);
di.Cells.Add(tc);
di.Cells.Add(tc1);
Table t = (Table)DataGrid1.Controls[0];
t.Rows.Add(di);
}

before i call this function, say i have 5 rows in my datagrid. After this function is called, which adds a new row to datagrid, still my datagrid shows it has only 5 rows....what could be the reason

here is the source code

private void AddRow()
{
TableCell tc = new TableCell();
tc.Controls.Add(new LiteralControl("NewRow"));

DataGridItem di = new DataGridItem(DataGrid1.Items.Count+1,DataGrid1.Items.Count+1,ListItemType.It
em);
di.Cells.Add(tc);
di.Cells.Add(tc1);
Table t = (Table)DataGrid1.Controls[0];
t.Rows.Add(di);
}

This code isn't adding rows to a datagrid, it's adding rows to a table which
happens to be in the datagrid.

Have you set the DataSource property of the datagrid? If so, then all the
rows will come from the datasource, and the way to add a row to the grid
would be to add the row to the source.

1) AddRow() is never called
2) DataBind() is being called after AddRow()
3) I'm not sure this could be the reason, but try:
new DataGridItem(DataGrid1.Items.Count+1,0,ListItemType.Item);
