Display multiple data fields in BoundField of Gridview
提问by andrew slaughter
I have an asp:GridViewwhich is bound. Within this I have multiple columns, I'm trying to get the data from two database fields concatenated into one field.
我有一个asp:GridView绑定的。在此我有多个列,我试图从连接到一个字段的两个数据库字段中获取数据。
How to do this?
这该怎么做?
Something like this?
像这样的东西?
asp:BoundField DataField="field1 + ' ' + field2" HeaderText="Status" SortExpression="info"

Try like this. If u are using two datasets make to one datatable and bind it to gridview.
像这样尝试。如果您使用两个数据集制作一个数据表并将其绑定到 gridview。
<asp:BoundField DataField="<%# DataBinder.Eval(Container.DataItem, "f1")%>+ ' ' + <%# DataBinder.Eval(Container.DataItem, "f2")%>" HeaderText="Status" SortExpression="info"/>

Pretty sure you need to use a TemplateField instead of BoundField for this.
很确定您需要为此使用 TemplateField 而不是 BoundField 。
In your GridView Columns Block:
在您的 GridView 列块中:
<asp:TemplateField HeaderText="Name">
<ItemTemplate>
<%# Eval("FirstName") + " " + Eval("LastName")%>
</ItemTemplate>
</asp:TemplateField>

ToolTip='<%# Eval("LastName") & "-" & Eval("FirstName") %>'

Just for completeness, cause I searched a solution and came first here...
只是为了完整性,因为我搜索了一个解决方案并首先来到这里......
You have more flexibility by using string.Format()
您可以通过使用获得更大的灵活性 string.Format()
<asp:TemplateField HeaderText="Status">
<ItemTemplate>
<%# string.Format("{0} {1}", Eval("field1") ,Eval("field2"))%>
</ItemTemplate>
</asp:TemplateField>
Here you can also use the power of string.Format()to format date and number types as descriped here: https://docs.microsoft.com/en-us/dotnet/standard/base-types/formatting-types
在这里,您还可以使用此处所述的string.Format()格式化日期和数字类型的功能:https: //docs.microsoft.com/en-us/dotnet/standard/base-types/formatting-types
Sample:
样本:
<%# String.Format("{0:MM/dd/yyyy} - {1:N2}", Eval("dateValue1"), Eval("decimalValue2")) %>
Another option is to do it in a custom method with code behind
另一种选择是在带有代码的自定义方法中执行此操作
ASPX:
ASPX:
<asp:TemplateField HeaderText="Status">
<ItemTemplate>
<asp:Label runat="server" Text='<%#GetStatus(Eval("Status1"),Eval("Status2")) %>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
Codebehind:
代码隐藏:
public string GetStatus(object Status1, object Status2)
{
return (string)Status1 + " " + (string)Status2;
}
