如何在GridView中获取选定的行和列值

问题描述

大家好，

我有三个模板字段，一个是超链接1，第二个是ImageButton1，第三个是InageButton2.

Hi All,

i''ve three template fields and one is hyperlink1,second is ImageButton1 ,third is InageButton2.

<asp:TemplateField>
                                                <ItemTemplate>
         <asp:HyperLink ID="HyperLink1" Text='<%# Eval("RowName") %>' runat="server"></asp:HyperLink>
                                                </ItemTemplate>
                                                <ItemStyle BorderStyle="None" />
                                                </asp:TemplateField>

                   <asp:TemplateField>
                                                <ItemTemplate>
 <asp:ImageButton ID="ImageButton1"  CommandArgument='<%# Eval("1") %>' CommandName="ib1"

 Visible='<%# MyVisible(Eval("1").ToString()) %>' runat="server" ImageUrl="~/images/wchair.jpg" />
                                                </ItemTemplate>
                                                <ItemStyle BorderStyle="None" />
                   </asp:TemplateField>

                   <asp:TemplateField>
                                                <ItemTemplate>
 <asp:ImageButton ID="ImageButton2" runat="server" CommandArgument='<%# Eval("2") %>'

 CommandName="ib2" Visible='<%# MyVisible(Eval("2").ToString()) %>' ImageUrl="~/images/wchair.jpg" />
                                                </ItemTemplate>
                                                <ItemStyle BorderStyle="None" />
                                                </asp:TemplateField>

在服务器端，我想获取行值，即超链接文本.为此，我使用了以下代码

In server side i want to get row value ie hyperlink text.For that i''ve used follwing code

protected void gvScreenLayout_RowCommand(object sender, GridViewCommandEventArgs e)
    {
        int ColumnIndex = Convert.ToInt32(e.CommandName);//this is fine


       HyperLink col = (HyperLink)gvScreenLayout.SelectedRow.FindControl("HyperLink1");//Error:Object is not set to an instance
       string columnindex = col.Text;
    }

但是抱歉，这不起作用.请使用示例

But Sorry this is not working.Please help me out in this with examples

推荐答案

protected void gvScreenLayout_RowCommand(object sender, GridViewCommandEventArgs e)
      {
          int rowIndex = Convert.ToInt32(e.CommandArgument);
          HyperLink hyperlink = (HyperLink)gvScreenLayout.Rows[rowIndex].FindControl("HyperLink1");
      }
