casting problem in Datagrid - Option Strict in use

[fabrice]

Hello


I have a little problem with casting in a Datagrid Control. I'm using Option
Strict in my web application.

In a Template Column, I put in an ImageButton Control with a Command
Argument using Container.DataItem.
Différent expressions as
System.Convert.ToString(Container.DataItem("Column"))) bring an Error :

BC30574: Option Strict ...Late Binding


I would like to use Container.DataItem instead of DataBinder.Eval for
optimisation. But I don't managed to find the right Cast.
I try these solutions with no success:

CommandArgument='<%# String.Format("{0:c}", (CType(Container,
DataGridItem).DataItem("Column"))) %> '

or

CommandArgument='<%#CType(Container, DataGridItem).DataItem,
"IDEBRE").ToString()%> '



This solution works :

CommandArgument='<%# Convert.ToString(DataBinder.Eval(CType(Container,
DataGridItem).DataItem, "idebre"))) %>'

....but use DataBinder.Eval argument.



I' don't understand the Casting problem (Late Binding) with
Container.DataGridItem.


Thanks for you help.

Fabrice.

Try adding the following to the ItemCreated event in the VB file


If e.Item.ItemType = ListItemType.Item Then

Dim drvTemp As System.Data.DataRowView
drvTemp = CType(e.Item.DataItem, System.Data.DataRowView)
CType(e.Item.FindControl("imgButtonID"),
LinkButton).CommandArgument = CType(drvTemp.Row.Item("Column"), System.String)
End If

If e.Item.ItemType = ListItemType.AlternatingItem Then
Dim drvTemp As System.Data.DataRowView
drvTemp = CType(e.Item.DataItem, System.Data.DataRowView)
CType(e.Item.FindControl("imgButtonID"),
LinkButton).CommandArgument = CType(drvTemp.Row.Item("Column"), System.String)
End If
