DataForm.NET v3.4 is here.

File upload/download functionality is added to both eDataForm and eGridForm components. Use eDataForm component to upload or download files. If file is a picture, it can show up in eDataForm directly. Use eGridForm component to download or preview files.

EasyViewState v1.0 is just released. It removes viewstate from web pages and keeps them on the server.

• Reduces the size of web pages and provides noticeable performance improvement.
• Uses Cache, File, SQL SERVER or ORACLE as persistence medium.
• Supports ALL existing/new ASP.NET 1.1, ASP.NET 2.0 and AJAX.NET web applications.
• Requires no code changes nor recompilation. Just modify web.config.

Row span property added to eDataForm component to support more flexible and complex layout.

New features added to Criteria component

• Provides cross-table criteria for eGridForm as long as those tables are used by eGridForm or in JOIN statement of each eGridForm column. For instance, you can search ORDER DETAILS table by  Product Name which belongs to PRODUCT table.
• More Criteria Operators added to eCriteria component, such as Not Between, Starts With and Ends With, etc.
• The second field is configurable when Between operator is specified. For instance, you can specify default value for the second field.

Fully compatible with ASP.NET AJAX. DataForm.NET manager now supports preview in AJAX.NET mode, as long as the machine has had AJAX.NET installed.

No coding required nor code changes to use ALL of above enhancements.

Minor enhancements and bugs fix.

DataForm.NET v3.4 更新信息：

對(duì) eDataForm 以及 eGridForm 組件添加了文件上傳/下載功能。使用 eDataForm 組件，能夠上傳或者下載文件。如果文件為圖片，eDataForm 中可以立即顯示。使用 eGridForm 組件，能夠下載或者預(yù)覽文件。

發(fā)布了 EasyViewState v1.0. 它刪除了網(wǎng)頁(yè)中的 viewstate, 而保留了服務(wù)器中的eGridForm.

• 縮小了網(wǎng)頁(yè)大小，提供了顯著的性能改進(jìn)。
• 使用 Cache, File, SQL SERVER 或者 ORACLE 做為持續(xù)介質(zhì)。
• 支持所有的現(xiàn)有/新的 ASP.NET 1.1, ASP.NET 2.0 and AJAX.NET 網(wǎng)頁(yè)應(yīng)用程序。
• 不需要更改代碼以及重編譯。僅需修改 web.config.

對(duì) eDataForm 組件添加了行跨度屬性，以支持更靈活以及復(fù)雜的布局。

對(duì) Criteria 組件添加的新特性如下：

• 對(duì) eGridForm 提供了跨表 criteria, 就像是由eGridForm使用這些表一樣，或者在每一個(gè)eGridForm列的 JOIN 語(yǔ)句中使用一樣。例如，你可以按照 PRODUCT 表中的 Product Name 來(lái)查找 ORDER DETAILS 表。
• 對(duì) eCriteria 組件添加了更多的 Criteria 操作符，如 Not Between, Starts With 以及 Ends With 等。
• 當(dāng)指定了 Between 操作符后，可以設(shè)置 second field. 例如，你可以對(duì)第二字段指定默認(rèn)值。

與 ASP.NET AJAX 完全兼容。現(xiàn)在，DataForm.NET manager支持在AJAX.NET 模式下進(jìn)行預(yù)覽，就如同機(jī)器上已經(jīng)安裝了 AJAX.NET 一樣。

使用以上所有改進(jìn)時(shí)，不需要編碼，也不需要更改編碼。

進(jìn)行了多個(gè)微小性改進(jìn)以及錯(cuò)誤修復(fù)。
