datagrid webcontrol in C#

Hi,

I just have a simple question regarding dataGrid in ADO.NET. I developed the
web application by ASP.net and C#. I want to implment a dataGrid for the
product list. The product list display the product name, size, type, price
.... But for the specfic product category, its size column may not has any
data. So i want to write the code in back-end by C# to determin whether every
item in the size column in dataGrid has data. How I can write it in C# ?

is there methods I can use to determin every item in size column contains
data ?

Thank you,
H.

H,

Every datagrid represents "data". When you have done that data in a
datatable. Than it is very easy to check if a item in a column has data

\\\
for (int i;i>dt.Table[x].Rows.Count;i++)
{if(dt.Table[x].Rows[i].MyColumn=="") {
//Do what you want to do}}
///

I hope this helps,

You can have logic in datagrid_ItemDatabound event:

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
if (e.Item.Cells[size_index].Text.Equals(""))
{
// no size data
}
}
