解决方案

Asssuming您正在使用绑定列的前三列，你要处理的的LinkBut​​ton -Click事件（而不是的如 RowCommand 的 GridView控件）

 保护无效CloseLinkClicked（对象发件人，EventArgs的发送）
{
    VAR closeLink =（控制）发送;
    GridViewRow行=（GridViewRow）closeLink.NamingContainer;
    字符串firstCellText = row.Cells [0]。文本; // 我们到了
}
 

如果您使用的是模板列和值 AA 是一个标签（如 LblValue ）

 标签lblValue =（标签）row.FindControl（LblValue）; // lblValue.Text =AA
 

I have a gridviewMain. Whenever I click the CLOSE linkbutton for row 1 I want to get the value aa. Click Close on row 2 get the value of bb. Any ideas.

A    B   C  
aa  xx   3  CLOSE 
bb  yy   4  CLOSE
cc  zz   5  CLOSE

aspx

 <asp:BoundField DataField="afield" HeaderText="A" 
     SortExpression="afield" >
    <ItemStyle HorizontalAlign="Center" />
 </asp:BoundField>
 <asp:BoundField DataField="bfield" HeaderText="B" SortExpression="cfield" >
     <ItemStyle HorizontalAlign="Center" />
  </asp:BoundField>
  <asp:BoundField DataField="cfield" HeaderText="C" SortExpression="cfield" >
     <ItemStyle HorizontalAlign="Center" />
   </asp:BoundField>
 <asp:TemplateField ShowHeader="False">

       <ItemTemplate>
          <asp:LinkButton ID="lbClose" runat="server" CausesValidation="False"  CommandName="CloseClicked" Text="Close"></asp:LinkButton>

        </ItemTemplate>

                    </asp:TemplateField>

解决方案

Asssuming that you are using BoundFields for the first three columns and you want to handle the LinkButton-click event (instead of the e.g. RowCommand of the GridView):

protected void CloseLinkClicked(Object sender, EventArgs e)
{
    var closeLink = (Control) sender;
    GridViewRow row = (GridViewRow) closeLink.NamingContainer;
    string firstCellText = row.Cells[0].Text; // here we are
}

If you are using TemplateFields and the value aa is in a Label (e.g. LblValue):

Label lblValue = (Label) row.FindControl("LblValue"); // lblValue.Text = "aa"
