Change from ASPxGrid to ASPxGridView

Reply Contact

Do you have a document to help converting projects from Aspxgrid to gridview ? I searched the help but found nothing

For example doesn't the processingmode property exist anymore ?

Is the aspxdatacontroller still usable or not ?

Thanks

Hi Paolo,
We will blog about it or create a knowledgebase article.
It is a brand new product based on ASP.Net v2 and our new ASP.Net shared library. It is a callback based control (the most functionality has been implemented via callbacks) and it is completely different from the old grid. We haven’t used a single line of code from the old grid.

It is unclear to me if the change involves the various aspxtextboxes also.

I have a page with a grid and several textboxes. I attached all textboxes to an aspxdatacontroller.

Is this correct ?

Hi Paolo,
The ASPxDataController is part of our old asp.net controls. The new controls don’t use it at all. The new asp.net dll’s don’t have any reference to the old asp.net dll’s.
Please refer to our Focused Row demo (http://demos.devexpress.com/ASPxGridViewDemos/Rows/FocusedRow.aspx) to get the ideas how you can achieve a similar functionality.

Hi Andrew

I saw the demo. In fact I am trying to follow it in a project.

But in the demo the detail fields are not data aware. Does this mean that we must handle

set / get of each fields manually ? No more use of AspxTextbox ? Only plain input text ?

I saw now the data binding demo. I suppose it can answer my question isn'it ?

Thanks

Bye

In the current version you should get/set values manually for editors located outside the grid.
We are going to improve this in upcoming major versions.
You don't need to do anything for in-place editors.

I have a page with a grid and several editors outside. Browsing the records in the grids should

synchronize the editors. With aspxgrid I resolved using the grid in server mode and rebinding the editors at the postback on focused row change.

Are you saying that this would be impossible with gridview in this version ?

Even using a detailsview with editors inside ?

It is very important to me since I have to decide which component use.

GridView seems quicker and thougth for the .net 2.0 version but I must be able to do this

kind of thing to use it.

Ok, I got you at last.

Sure, you can do it. Our editors and detailView work fine.

You have to set the grid EnableCallbacks property to false to do it. The ASPxGridView will work via postbacks.

If you put the grid and editors inside the MS Ajax Update Panel than you will get the Ajax experience.

Hi Andrew

I tried the approach you suggested but the focusedrowchanged event fires only once at startup (and with focusedrowindex = -1).

I disabled EnableCallbacks and defined an event server side attached to the focusedrowchanged.

Here is my markup:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="TestDesignTime.aspx.cs" Inherits="TestDesignTime" %>

<%@ Register Assembly="DevExpress.Web.ASPxGridView.v7.2, Version=7.2.1.0, Culture=neutral, PublicKeyToken=9b171c9fd64da1d1"
Namespace="DevExpress.Web.ASPxGridView" TagPrefix="dxwgv" %>
<%@ Register Assembly="DevExpress.Web.ASPxEditors.v7.2, Version=7.2.1.0, Culture=neutral, PublicKeyToken=9b171c9fd64da1d1"
Namespace="DevExpress.Web.ASPxEditors" TagPrefix="dxe" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
      <dxwgv:aspxgridview id="GrdMain" runat="server" autogeneratecolumns="False" datasourceid="DtsTabCdc"
        keyfieldname="ID" style="z-index: 100; left: 18px; position: absolute; top: 44px" OnCustomCallback="GrdMain_CustomCallback" EnableCallBacks="False" OnFocusedRowChanged="GrdMain_FocusedRowChanged"><Columns>
          <dxwgv:GridViewCommandColumn VisibleIndex="0">
            <DeleteButton Visible="True">
            </DeleteButton>
            <EditButton Visible="True">
            </EditButton>
            <NewButton Visible="True">
            </NewButton>
          </dxwgv:GridViewCommandColumn>
          <dxwgv:GridViewDataTextColumn Caption="ID" FieldName="ID" VisibleIndex="1">
          </dxwgv:GridViewDataTextColumn>
          <dxwgv:GridViewDataTextColumn Caption="DESCRIZIONE" FieldName="DESCRIZIONE" VisibleIndex="2">
          </dxwgv:GridViewDataTextColumn>
</Columns>

<SettingsBehavior ConfirmDelete="True" AllowFocusedRow="True"></SettingsBehavior>

<ClientSideEvents RowClick="function(s, e) {
    //GrdMain.StartEditRow(e.visibleIndex);
}" FocusedRowChanged="function(s, e) {
    //GrdMain.PerformCallback(s.GetFocusedRowIndex());
}"></ClientSideEvents>

<SettingsEditing Mode="EditForm"></SettingsEditing>
</dxwgv:aspxgridview>

Thanks in advance for any tips/suggestion

Hi Paolo,
Before suggesting anything I had to try first.
The problem is, that we did not take your scenario into account. We assumed that the focused row feature will be used on the client only. That was our fault.
Anyway, we’ve made the required changes in v7.2.2, which we will hopefully release this week.
In the new version, you will have to:
1) Set the EnableCallbacks property to false.
2) Call the client PerformCallback method on the focused changed event (actually it will call a post back, because the EnableCallbacks property is false)
<ClientSideEvents FocusedRowChanged="function(s, e) { grid.PerformCallback(); }"/>
3) On the server FocusRowChanged event rebind your DetailView.
I tried this with the latest bits, and it works fine.

Hi Andrew,

Thank you very much for your reply.

The postback on focusedrowchange is not a "requirement" for me. In fact I followed

this way because it seemed too difficult to me to rebind all the detail fields client side.

From your answer I guess it is possible. May you have an example ? I am interested specifically in see the js code for re-bindind data control editors to the datasource filtered on a (new) primary key.
Thanks
