Iterate through an ASP.NET datagrid

2008-03-14T15:07:00Z

Here's how to loop through an ASP.NET datagrid

Dim a As Int16
For a = 0 To Me.grdLines.Items.Count - 1
    'get a reference to the row id
    intDexRowID = CType(Me.grdLines.Items(a).FindControl("lblDexRowID"), Label).Text
Next

Datagrid ItemDataBound event

Here is the 'starter code' that I use when creating the ItemDataBound event. It is not guaranteed to make sense, but exists so that I have sample code that I can alter to get a faster start.

 Protected Sub grdLines_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.DataGridItemEventArgs) Handles grdLines.ItemDataBound
    If e.Item.ItemType = ListItemType.Item OrElse e.Item.ItemType = ListItemType.AlternatingItem Then


        'get a reference to a data item
        Dim isRed As Integer = CType(DataBinder.Eval(e.Item.DataItem, "red"), String)


        'get a reference to a control...
        Dim lblLocncode As Label = e.Item.FindControl("lblLocncode")


    End If


End Sub
