问题 If I bind GridView (via DataSourceID attribute) to SqlDataSource and set SelectCommand and UpdateCommand attributes, then everything works perfectly. But I’ve noticed that if I, for whatever reason, also manually call DataBind() inside Page_Load(), then SqlDataSource doesn’t perform any updates, even though SqlDataSource.Updating and SqlDataSource.Updated events do fire when GridView’s Update button is clicked. Could someone explain why updates don’t happen? 回答1: It's because the Page_Load is

问题 I'm trying to implement a basic GridView gallery as per the Android Developer Guide/Tutorial. The ImageViews inside my grid are Bitmaps taken from a user's camera. This works fine except for the fact that my images are incredibly small. My xml: <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/gridview" android:layout_width="match_parent"

问题 It's possible to have "by-row" columns definition in a Grid? For example, I need a grid like this: id | name | options ====================================== int | string | combobox(1,2,3) int | string | combobox(1,2,3,4,5) int | string | combobox(1,2,3) int | string | combobox(5,6,7) The combobox possible values are defined for that column in the initialization...is there a way to define that per row or perhaps some method to define after the rendering? 回答1: You have several options here.

Thanks is advance! ` string sqlText = "SELECT * FROM Images WHERE img

BoundField 默认的数据绑定类型，通常用于显示普通文本 CheckBoxField 显示布尔类型的数据。绑定数据为TRUE时，复选框数据绑定列为选中状态；绑定数据为FALSE时，则显示未选中状态。在正常情况下，CheckBoxField显示在表格中的复选框控件处于只读状态。只有GridView控件的某一行进入编辑状态后，复选框才恢复为可修改状态。 CommandField 显示用来执行选择，编辑或删除操作的预定义命令按钮，这些按钮可以呈现为普通按钮，超链接，图片等外观。 通过字段的ButtonType属性可变更命令按钮的外观，默认为Link即超链接，另外两个属性值分别为Image和Button。例如，要选择以图片形式显示编辑按钮外观，一定要设置ButtonType属性为Image。 ImageField 用于在GridView控件呈现的表格中显示图片列，通常绑定内容是图片是图片的路径。 HyperLinkField 允许将绑定的数据以超链接的形式显示出来。开发人员可定义绑定超链接的显示文字、超链接的URL以及打开窗口的方式等。 ButtonField 可以为GridView控件创建命令按钮。开发人员可以通过按钮来操作其所在行的数据。 TemplateField 允许以模板形式自定义数据绑定列的内容。 　　ItemTemplate 显示每一条数据的模板 　

ASP GridView Refresh after Excel Export not working

问题 I have a Gridview inside an Ajax UpdatePanel. Inside each GV row I have a checkbox field. The idea is that the user checks the lines they want, and click a button to both update a label in that row as "shipped" and then also export the checked lines to an xls file (csv really). When my codebehind fires it loops through the gridview rows, looks for the checks, updates the database to mark each line and then I use .DataBind() to refresh the grid. This works perfectly and as expected. Now I want
