我有2个表,我想从中获取数据。第一个表是Contractor表,其中包含承包商个人信息,第二个表是Company表,其中包含2列,CompanyName和CompanyID。两个表都有相同的列,CompanyID。
我当前的代码有一个gridview,其中包含" Select" column,SelectedIndexChanged返回数据库中的值以填充文本框。
我想要做的是获取公司名称而不是填入文本框的公司ID(txtCompany),如何修改下面的当前代码呢?
ASPX
<asp:TextBox ID="txtFirstName" runat="server"></asp:TextBox>
<asp:TextBox ID="txtLastName" runat="server"></asp:TextBox>
<asp:TextBox ID="txtPID" runat="server"></asp:TextBox>
<asp:TextBox ID="txtCompany" runat="server"></asp:TextBox>
<asp:GridView ID="TDetails" DataSourceID="SqlDataSource1" DataKeyNames="PersonID" AutoGenerateColumns="false" runat="server" OnSelectedIndexChanged="TDetails_SelectedIndexChanged" >
<HeaderStyle BackColor="gray" ForeColor="White" />
<Columns
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="lbtnSelect" runat="server" CommandName="Select" Text="Select" />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Last Name">
<ItemTemplate>
<asp:Label ID="lblLastName" runat="server" Text='<%#Eval("LastName") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="First Name">
<ItemTemplate>
<asp:Label ID="lblFirstName" runat="server" Text='<%#Eval("FirstName") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Company" Visible="false">
<ItemTemplate>
<asp:Label ID="lblCompany" runat="server" Text='<%#Eval("CompanyID") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="PersonID" Visible="false">
<ItemTemplate>
<asp:Label ID="lblPID" runat="server" Text='<%#Eval("PersonID") %>' />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
.CS
protected void TDetails_SelectedIndexChanged(object sender, EventArgs e)
{
txtPID.Text = TDetails.DataKeys[TwicDetails.SelectedRow.RowIndex].Value.ToString();
txtLastName.Text = (TDetails.SelectedRow.FindControl("lblLastName") as Label).Text;
txtFirstName.Text = (TDetails.SelectedRow.FindControl("lblFirstName") as Label).Text;
txtCompany.Text = (TDetails.SelectedRow.FindControl("lblCompany") as Label).Text;
}

您可以修改SQL查询以获取CompanyName
以及如何获取CompanyId
并将其绑定到gridview并将可见性设置为 false ,最后您可以像设置其他控件一样设置文本框的值: -
SQL查询: -
SELECT CompanyId, CompanyName, ....
FROM tblCompany..
.aspx的: -
<asp:TemplateField HeaderText="Company" Visible="false">
<ItemTemplate>
<asp:Label ID="lblCompanyName" runat="server" Text='<%#Eval("CompanyName") %>' />
</ItemTemplate>
</asp:TemplateField>
