我有2個表,我想從中獲取數據。第一個表格是承包商個人信息的承包商表格,第二個表格是公司表格,其中有兩列,CompanyName和CompanyID。兩個表具有相同的列,CompanyID。如何獲取SelectedIndexChanged以獲取公司名稱而不是companyid到文本框,2個不同的表中?
當前代碼我有一個帶有「選擇」列的GridView,SelectedIndexChanged返回數據庫中的值以填充文本框。
我想要做的是獲取公司的名稱,而不是公司名稱填入文本框(txtCompany),我該如何修改我下面的當前代碼這樣做?
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">

<asp:Label ID="lblCompany" runat="server" Text='<%#Eval("CompanyID") %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="PersonID" Visible="false">

</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
