将列绑定到与gridview不同的实体源

本文介绍了将列绑定到与gridview不同的实体源的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我有一个gridview绑定到一个Entity DataSource(权限)。其中一列列出了UserId,它是另一个表中的主键。如何用User Entity DataSource将相应的Name替换为UserId?

解决方案

将其排序..



 < asp:TemplateField HeaderText =ApprovedBySortExpression =ApprovedBy> 
< ItemTemplate>
< asp:Label ID =lblUserrunat =serverText ='<%#GetApprover(Eval(ApprovedBy)ToString())%>'/>
< / ItemTemplate>
< / asp:TemplateField>

和代码:

  protected string GetApprover(string ApproverId)
{
int approver = Convert.ToInt32(ApproverId);
var approversList =(from a in EntUsers.Users
where a.UserId == approver
select a.Name).FirstOrDefault();

return approversList;
}


I have a gridview bound to an Entity DataSource (Permissions). One of the columns lists a UserId, which is the primary key in another table. How do I go about replacing that UserId with the corresponding Name form the Users Entity DataSource?

解决方案

Sorted it out..

<asp:TemplateField HeaderText="ApprovedBy" SortExpression="ApprovedBy" >
            <ItemTemplate>
                <asp:Label ID="lblUser" runat="server"  Text='<%# GetApprover(Eval("ApprovedBy").ToString()) %>'/>
            </ItemTemplate>
</asp:TemplateField>

and code behind:

protected string GetApprover(string ApproverId)
    {
        int approver = Convert.ToInt32(ApproverId);
        var approversList = (from a in EntUsers.Users
                             where a.UserId == approver
                            select a.Name).FirstOrDefault();

        return approversList;
    }
