Hi, I have created a second gridview when customer clicks on select link with
this code:



Protected Sub GridView1_RowCommand(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.GridViewCommandEventArgs) Handles
GridView1.RowCommand

Select Case e.CommandName

Case "Select"

GridView1.SelectedIndex = e.CommandArgument
Dim index As Integer = Convert.ToInt32(e.CommandArgument)

' Retrieve the row that contains the button clicked
' by the user from the Rows collection.
Dim row As GridViewRow = GridView1.Rows(index)
Dim mival = Server.HtmlDecode(row.Cells(1).Text)
HiddenField1.Value = mival
TabContainer1.Visible = True
Dim sqlConn As System.Data.SqlClient.SqlConnection
Dim sqlCmd As System.Data.SqlClient.SqlCommand
Dim strConnection As String
strConnection =
ConfigurationManager.ConnectionStrings("SIPConnectionString").ConnectionString
sqlConn = New
System.Data.SqlClient.SqlConnection(strConnection)
sqlCmd = New System.Data.SqlClient.SqlCommand("SELECT
responsablepropuesta.respgrupo as IDRespGrupo, tb1.nombre as RespGrupo,
responsablepropuesta.resppropuesta as IDRespProp, tb2.nombre as RespPropuesta
FROM responsablepropuesta INNER JOIN usuario tb1 ON tb1.idusuario =
responsablepropuesta.respgrupo INNER JOIN usuario tb2 ON tb2.idusuario =
responsablepropuesta.resppropuesta where idpropuesta='" & mival & "'",
sqlConn)

sqlConn.Open()
GridView2.DataSource = sqlCmd.ExecuteReader()
GridView2.DataBind()
sqlConn.Close()
End Select

End Sub


And when users tries to clicks on Edit link, runs this code:



Protected Sub GridView2_RowCommand(ByVal sender As Object, ByVal e As
System.Web.UI.WebControls.GridViewCommandEventArgs) Handles
GridView2.RowCommand
Select Case e.CommandName

Case "Edit"

GridView2.SelectedIndex = e.CommandArgument
Dim index As Integer = Convert.ToInt32(e.CommandArgument)

' Retrieve the row that contains the button clicked
' by the user from the Rows collection.
Dim row As GridViewRow = GridView2.Rows(index)
Panel1.Visible = False
Panel2.Visible = True

End Select
End Sub



But when it finish this part, it displays an error:

The GridView 'GridView2' fired event RowEditing which wasn't handled.
