Table row onclick event that runs codebehind

由 纵饮孤独 提交于 2019-12-06 07:50:37
I've inherited an ASP.NET project that has poorly designed HTML; in one section, the tags are wrapped with an tag to allow for "click the row to view the information" functionality.

WPF MVVM Code Behind Best Practices

由 ﹥＞﹥吖頭↗ 提交于 2019-12-06 05:26:32
问题 I'm a student learning C# with WPF using the MVVM pattern. Recently I have been working on a [art of my application (a custom splash screen) that should not be closed when I don't want it to. I have been searching the web for a good way of doing this without code-behind. Unfortunately after days I still did not find a satisfying way. Then I came to think of a way to do it myself, with help of just one line of code in the constructor of my view. It still makes my code testable and decouples

由 馋奶兔 提交于 2019-12-06 02:00:39
Okay I clearly haven't fed google the right query or I would've found out by now. I'm hoping someone on this forum can help me. So I have a datatable that I'm adding rows to based on a datareader that's getting its info from an sql query executed over a database. So far, so good. Now, one of those columns is called 'analysis', and I need its background color to be green if the preceding two columns are matched, and red otherwise. If I can't touch the background color, I'd like to insert a special character, any javascript that isn't interpreted as text. Simply put, I'd like css control over a

问题 How I can draw a circle in WPF (without code-behind) using min(width, height)/2 as radius? 回答1: you can do it in pure XAML you just need to use Binding for the values. You also have to make sure that everything is named <Grid Name="grdMain"> <Grid.ColumnDefinitions> <ColumnDefinition Width="75" Name="Col1" /> <ColumnDefinition Width="100" Name="Col2" /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition Height="75" Name="Row1" /> <RowDefinition Height="100" Name="Row2" /> </Grid
