如何从listview传递catID并将其作为ObjectDataSource中的SelectParameters“NewsRepeaterODS”？

感谢

Answer 1

Protected Sub CategoriesList_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewItemEventArgs) Handles CategoriesList.ItemDataBound
    ' Find the Inner DataSource control in this Row.
    Dim NewsRepeaterODS As ObjectDataSource = DirectCast(e.Item.FindControl("NewsRepeaterODS"), ObjectDataSource)

    ' Set the SelectParameter for this DataSource control
    ' by re-evaluating the field that is to be passed.
    Dim CatIDLtl As Literal = e.Item.FindControl("CatIDLtl")
    NewsRepeaterODS.SelectParameters("CatID").DefaultValue = CatIDLtl.Text
End Sub
