如何调用函数并将值从aspx传递给aspx.cs [英] How to call a function and pass a value from aspx to aspx.cs

问题描述

我需要调用一个函数并传递一个从DB获取的值。



Gridview如下所示。当Gridview获取第一列的值时，我需要调用一个函数，将获取的值作为参数传递给它并返回一个替换值。



简而言之，我需要传递<％＃Eval（LeaveType）％>函数：<％= GetLeaveType（）％> 。



如何实现这一目标。请帮帮我。

I need to call a function and pass a value which is fetched from DB.

The Gridview is as follows. When Gridview fetches the value of first column, I need to call a function, pass the fetched value as argument to it and return a replacement value.

In short, I need to pass <%#Eval("LeaveType")%> to the function: <%= GetLeaveType() %> .

How do I achieve this. Please help me out.

<Columns>
        <asp:templatefield headertext="LeaveType">
            <itemtemplate>
                <%#Eval("LeaveType")%>
            </itemtemplate>

            <edititemtemplate>
                <%#Eval("LeaveType")%>
            </edititemtemplate>
        </asp:templatefield>

        <asp:templatefield headertext="Balance">
             <itemtemplate>
                 <%#Eval("Balance")%>
             </itemtemplate>

             <edititemtemplate>
                  <asp:textbox id="BalanceTxtBox"

                       text='<%#Eval("Balance")%>'

                       width="45"

                       runat="server"/>
             </edititemtemplate>
         </asp:templatefield>
         ....
         ....
         <asp:CommandField ShowEditButton="true" HeaderText="Update Record" ItemStyle-Width="30px" />
     </Columns>
</asp:GridView>

推荐答案

尝试

'<%#GetLeaveType(Eval("LeaveType"))%>'

你可能需要类似于下面的代码隐藏方法

you may need codebehind method similar to below

protected string GetLeaveType(object leaveType)
{
  return "From codebehind";
}
