Computed columns in datagrid

[Raymond Du]

Hi,

Can I have computed columns in a datagrid? If yes, how?

TIA

[mortb]

one way:

add a column
insert values in it in the event ItemDatabound

example column three is your computed value column:

private void _Grid_ItemDataB ound(object sender,
System.Web.UI.W ebControls.Data GridItemEventAr gs e)

{

if(e.Item.ItemT ype == ListItemType.It em || e.Item.ItemType ==
ListItemType.Al ternatingItem)

{

e.Item.Cells[3].Text = "your computed value";

}

}

cheers,
mortb

The data table have a compute() method that you can do this. Check this

A 3rd idea would be to do the computation in your data source.
e.g if it is a custom collection then add a readonly property to the
contained child class and have it return the computation. Then you can treat
it as a bound column in the grid.
