How to convert a long date to a short date in the gridview

First, let's look at the following code:

<Asp: gridview id = "gridview1" runat = "server" autogeneratecolumns = "false" datakeynames = "ID"
Performanceid = "accessperformance1">
<Columns>
<Asp: boundfield datafield = "datatime" dataformatstring = "{0: d}" headertext = "date"/>
</Columns>
</ASP: gridview>

Originally thought to use

Dataformatstring = "{0: d }"

You can convert a long date to a short date, but another person is disappointed with the result. After checking the relevant information, you will find that you still need to add the following sentence:

Htmlencode = "false"

The modified code is as follows:

<Asp: gridview id = "gridview1" runat = "server" autogeneratecolumns = "false" datakeynames = "ID"
Performanceid = "accessperformance1">
<Columns>
<Asp: boundfield datafield = "datatime" dataformatstring = "{0: d}" htmlencode = "false" headertext = "date"/>
</Columns>
</ASP: gridview>
