单击按钮时从GridView获取价值 [英] Get value from GridView when a button is clicked

问题描述

我有一个GridView，并且GridView有一个项目模板.现在，我需要获取包含所需值的第一个单元格的值，但是我尝试了以下操作，但不起作用，它返回一个"

I have a GridView , and the GridView has an item template. Now I need to get the value of the first cell which contains the value I need but I have tried the following and does not work, it eturns a ""

 int id = Convert.ToInt32(GridView.Rows[index].Cells[0].Text);

这是我在gridview中拥有的代码

Here is the code I have in the gridview

<Columns>
   <asp:TemplateField HeaderText="ID">
         <ItemTemplate>
             <asp:Label runat="server" ID="lblDepartmentID" Text='<%#DataBinder.Eval(Container.DataItem,"DepartmentID")%>' />
                                        </ItemTemplate>
                                        <HeaderStyle HorizontalAlign="Left" />
      </asp:TemplateField>

我必须强调，我不想使用GridView_RowCommand或其他GridView事件.我需要在单击同一页面上的按钮时拉出该值.

I have to emphazise that I do not want to use the GridView_RowCommand or other GridView events.. I need to pull this value upon clicking a button on the same page.

我该怎么做?

推荐答案

如果您尝试访问 Label 的文本值，则必须首先获取对 Label 的引用code>这样的控件:

If you are trying to access the text value of Label then you have to first get the reference to Label control like this:

Label lbl = (Label)GridView.Rows[index].FindControl("lblDepartmentID");

，然后使用它的 Text 属性获取所需的值:

and then use it's Text property to get the value required:

int id = Convert.ToInt32(lbl.Text);
