Cambiar el alcance de un archivo de etiquetas

Visual Studio 2008: Very easy process, just open the resource editor and change the value in the Access Modifier drop down menu from Internal to Public.


Visual Studio 2005: There is a free custom tool for that purpose called ResXFilePublicCodeGenerator – Download and install it. After the installation, open the properties window of the resource file and change the Custom Tool to ResXFilePublicCodeGenerator, than right click on the resource file and choose the Run Custom Tool from the drop down menu.

Hacer un distinct en listas

 nListaCircuitos = nListaCircuitos.OrderBy(Function(z) z.TN_COD_CIRCUITO).Distinct().ToList()
                        nListaCircuitos = nListaCircuitos.GroupBy(Function(x) x.TN_COD_CIRCUITO).[Select](Function(g) g.First()).ToList()

Cuando en el gridview esta paginado y se quiere obtener la fila

The problem is in the following line::

CommandArgument ='<%# Container.DataItemIndex%>'

---

the command argument not reset itself every time when move from page to another page..

• The answer is ::(in the case of ListView):

CommandArgument ='<%# ((ListViewDataItem)Container).DisplayIndex%>'

---

• The answer is :: (in the case of GridView):

CommandArgument='<%#((GridViewRow)Container).RowIndex%>'
