a Grid.DataItem should be a DataBinded Object type, right?

[Søren Hartig]

Hi all,

when we're binding a Collection of a Business Object into the Grid, the grid.DataItem should be that type, right?

I'm getting null :(

Code:

List<DocumentRow> rows = new List<DocumentRow>();

...

while (reader.Read())

{

DocumentRow row = DocumentRow.GetFromIdxDocumentId(int.Parse(reader[0].ToString()));

rows.Add(row);

}

...

gvDocs.DataSource = rows;

gvDocs.DataBind();

when trying to get the selected items...

foreach (GridItem gvr in gvDocs.SelectedItems)

{

DocumentRow row = (DocumentRow)gvr.DataItem;

list.Add(row.DocumentId);

}

gvr.DataItem is always null! :-(

how do I get the data back?

Hello Søren,

I have answered to the support ticket opened the same matter. Here is a quote of the answer:

Thank you for contacting us.

This is an expected behavior. You can reach the DataItem only in the ItemDataBound event handler. In any other later stage the grid is already bound and the DataItem will be null. In other words when the grid is bound the data source is not required anymore and it is null.

To retrieve the required data, you can make a call to the server to get the data or use the grid functionality to extract the data from the rows.

Let me know if I can assist you further.

May I ask you to continue our discussion in the opened support thread? Thus we will avoid any duplication and misunderstanding.

All the best,
