blocks|key|1712780|text|我在VB中使用了以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1712781|<asp:TemplateField+HeaderText="Active"+SortExpression="Active">

I use this code for VB:

<pre><code>&lt;asp:TemplateField HeaderText="Active" SortExpression="Active"&gt;
 &lt;ItemTemplate&gt;&lt;%#IIf(Boolean.Parse(Eval("Active").ToString()), "Yes", "No")%&gt;&lt;/ItemTemplate&gt;
&lt;/asp:TemplateField&gt;
</code></pre>

And this should work for C# (untested):

<pre><code>&lt;asp:TemplateField HeaderText="Active" SortExpression="Active"&gt;
 &lt;ItemTemplate&gt;&lt;%# (Boolean.Parse(Eval("Active").ToString())) ? "Yes" : "No" %&gt;&lt;/ItemTemplate&gt;
&lt;/asp:TemplateField&gt;
</code></pre>

blocks|key|1497784|text|向页面类添加一个方法，如下所示：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1497785|public+string+YesNo(bool+active)+
{
++return+active+?+"Yes"+:+"No";
}|code-block|syntax|javascript|1497786|然后在您的TemplateField中使用以下方法进行Bind：|offset|length|style|CODE|1497787|<%25#+YesNo(Active)+%25>|1497788|entityMap^0|0|0|5|D|R|4|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@$I|T|J|U|K|L]|$I|V|J|W|K|L]]|9|@]|A|$]]|$1|M|3|N|5|D|7|X|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|P|$]]

Add a method to your page class like this:

<pre><code>public string YesNo(bool active) 
{
 return active ? "Yes" : "No";
}
</code></pre>

And then in your <code>TemplateField</code> you <code>Bind</code> using this method:

<pre><code>&lt;%# YesNo(Active) %&gt;
</code></pre>

blocks|key|1497665|text|不-但您可以使用模板列：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1497666|<script+runat="server">
++TResult+Eval<T,+TResult>(string+field,+Func<T,+TResult>+converter)+{
+++++object+o+=+DataBinder.Eval(Container.DataItem,+field);
+++++if+(converter+==+null)+{
++++++++return+(TResult)o;
+++++}
+++++return+converter((T)o);
++}
</script>

<asp:TemplateField>
++<ItemTemplate>
+++++<%25#+Eval<bool,+string>("Active",+b+=>+b+?+"Yes"+:+"No")+%25>
++</ItemTemplate>
</asp:TemplateField>|code-block|syntax|javascript|1497667|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

Nope - but you could use a template column:

<pre><code>&lt;script runat="server"&gt;
 TResult Eval&lt;T, TResult&gt;(string field, Func&lt;T, TResult&gt; converter) {
 object o = DataBinder.Eval(Container.DataItem, field);
 if (converter == null) {
 return (TResult)o;
 }
 return converter((T)o);
 }
&lt;/script&gt;

&lt;asp:TemplateField&gt;
 &lt;ItemTemplate&gt;
 &lt;%# Eval&lt;bool, string&gt;("Active", b =&gt; b ? "Yes" : "No") %&gt;
 &lt;/ItemTemplate&gt;
&lt;/asp:TemplateField&gt;
</code></pre>

blocks|key|1497818|text|你可以用Mixin。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1497819|///+<summary>
///+Adds+"mixins"+to+the+Boolean+class.
///+</summary>
public+static+class+BooleanMixins
{

++++public+static+string+ToYesNoString(this+Boolean+boolean)

}|code-block|syntax|javascript|1497820|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

You could use a Mixin. 

<pre><code>/// &lt;summary&gt;
/// Adds "mixins" to the Boolean class.
/// &lt;/summary&gt;
public static class BooleanMixins
{
 /// &lt;summary&gt;
 /// Converts the value of this instance to its equivalent string representation (either "Yes" or "No").
 /// &lt;/summary&gt;
 /// &lt;param name="boolean"&gt;&lt;/param&gt;
 /// &lt;returns&gt;string&lt;/returns&gt;
 public static string ToYesNoString(this Boolean boolean)
 {
 return boolean ? "Yes" : "No";
 }
}
</code></pre>

blocks|key|1712747|text|或者，您可以在后台代码中使用ItemDataBound事件。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1712748|entityMap^0|E|D|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

Or you can use the <code>ItemDataBound</code> event in the code behind.

blocks|key|1497890|text|这是我一直以来的做法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1497891|<ItemTemplate>
++<%25#+Boolean.Parse(Eval("Active").ToString())+?+"Yes"+:+"No"+%25>
</ItemTemplate>|code-block|syntax|javascript|1497892|希望这能有所帮助。|1497893|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

This is how I've always done it:

<pre><code>&lt;ItemTemplate&gt;
 &lt;%# Boolean.Parse(Eval("Active").ToString()) ? "Yes" : "No" %&gt;
&lt;/ItemTemplate&gt;
</code></pre>

Hope that helps.

blocks|key|1497858|text|这是可行的：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1497859|Protected+Sub+grid_RowDataBound(sender+As+Object,+e+As+System.Web.UI.WebControls.GridViewRowEventArgs)+Handles+grid.RowDataBound

++++++++If+e.Row.Cells(3).Text+=+"True"+Then
++++++++++++e.Row.Cells(3).Text+=+"Si"
++++++++Else
++++++++++++e.Row.Cells(3).Text+=+"No"
++++++++End+If
++++End+If
End+Sub|code-block|syntax|javascript|1497860|其中，cells(3)是包含布尔字段的列的列。|offset|length|style|CODE|1497861|entityMap^0|0|0|3|8|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

This works:

<pre><code>Protected Sub grid_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grid.RowDataBound
 If e.Row.RowType = DataControlRowType.DataRow Then
 If e.Row.Cells(3).Text = "True" Then
 e.Row.Cells(3).Text = "Si"
 Else
 e.Row.Cells(3).Text = "No"
 End If
 End If
End Sub
</code></pre>

Where <code>cells(3)</code> is the column of the column that has the boolean field.

blocks|key|1712965|text|使用Format()-Function很容易|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1712966|Format(aBoolean,+"YES/NO")|code-block|syntax|javascript|1712967|请在此处查找详细信息：https://msdn.microsoft.com/en-us/library/aa241719(v=vs.60).aspx|offset|length|1712968|entityMap|0|LINK|mutability|MUTABLE|url|https://msdn.microsoft.com/en-us/library/aa241719(v=vs.60).aspx^0|0|0|B|1R|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|U|8|@]|9|@$I|V|J|W|1|X]]|A|$]]|$1|K|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|L|$M|$5|N|O|P|A|$Q|R]]]]

It's easy with Format()-Function

<pre><code>Format(aBoolean, "YES/NO")
</code></pre>

I have a ASP.NET <code>GridView</code> with a column mapped to a boolean. I want do display "Yes"/"No" instead of "True"/"False". Well actually I want "Ja"/"Nej" (in Danish).

Is this possible? 

<pre><code>&lt;asp:gridview id="GridView1" runat="server" autogeneratecolumns="false"&gt;
 &lt;columns&gt;
 ...
 &lt;asp:boundfield headertext="Active" datafield="Active" dataformatstring="{0:Yes/No}" /&gt;
 ...
 &lt;/columns&gt;
&lt;/asp:gridview&gt;
</code></pre>
