On a Button Click, making multiple cells editable in a selected row of a ReadOnly DataGrid

阅读更多关于 On a Button Click, making multiple cells editable in a selected row of a ReadOnly DataGrid

But I need both FirstName and LastName column cells in the edit mode. If I enclose the entire code of that event in a for loop as for (int i=2; i <=3; i++){...} only the last cell ( LastName ) column gets the edit mode. Remark : All other rows

阅读更多关于 Automatic tooltip when text is trimmed in DataGrid

问题 My application runs with C# and WPF (.net framework 4.0). My goal is to have a DataGrid in which the text in the cells is trimmed with an ellipsis, and automatically has a tooltip with the full text displayed only if the text in the cell is actually trimmed. Solution 1 : I'm currently using this to know if the text is trimmed or not: http://tranxcoder.wordpress.com/2008/10/12/customizing-lookful-wpf-controls-take-2/ The problem is that it only works when I resize the columns.

在这里红色的部分field字段显示得信息是，返回数据中的department得值，再此示例中因为返回数据是department是一个obj所以要用formatter属性进行重新的字段名定义 var column_views = [ {field: 'user_id', title: '工号', width: 70, sortable: true, align: 'center'}, {# {field: 'knowtype', title: '类型', width: 100, sortable: true},#} {field: 'name', title: '用户名称', width: 150, sortable: true, align: 'center'}, {field: 'department', title: '所属部门', width: 200, sortable: true, align: 'center', formatter:function(value, row, index){ return row.department.name }}, {field: 'email', title: '用户名称', width: 70, sortable: true, align: 'center'}, //{ title: '操作', width: 100,

用Repeater控件显示数据

阅读更多关于用Repeater控件显示数据

如果你正在使用ASP.NET，你一定对DataGrid 控件非常熟悉。DataGrid 控件提供了各种特性，通过这些特性可以很容易地在一个Web页面上以列表形式显示数据。但是，如果你不想使用HTML表格形式呢？此时，可以使用一个DataGrid的一个鲜为人知的兄弟控件，即Repeater 控件。Repeater 控件提供显示你所需要数据的灵活性。 Repeater 控件是什么？ Repeater是一个可重复操作的控件，也就是说，它通过使用模板显示一个数据源的内容，而你可以很容易地配置这些模板。Repeater包含如标题和页脚这样的数据，它可以遍历所有的数据选项并应用到模板中。与DataGrid和DataList 控件不同，Repeater 控件并不是由WebControl类派生而来。所以，它不包括一些通用的格式属性，比如控制字体，颜色，等等。然而，使用Repeater 控件，HTML(或者一个样式表)或者ASP.NET类可以处理这些属性。 HTML在哪里？ Repeater 控件与DataGrid (以及DataList) 控件的主要区别是在于如何处理HTML。ASP.NET建立HTML代码以显示DataGrid 控件，但Repeater允许开发人员决定如何显示数据。所以，你可以选择将数据显示在一个HTML表格中或者一个顺序列表中
