解决方案

在 Gridview RowCommand ，

 受保护  void  gvScripts_RowCommand（ object  sender，GridViewCommandEventArgs e）
 {
  if （e.CommandName ==   IFullView）
 {
  int  index =  0 ; 
  string  lstrVal =  ; 
 
  if （e.CommandArgument！=  ）
 {
 index = Convert.ToInt32（e.CommandArgument）; 
 lstrVal = gvScripts.DataKeys [index] .Value.ToString（）。Trim（）; 
} 
} 
} 

并且在。 aspx ，



我有一个 ImageButton 的列。因此，当我单击此按钮时，我需要获取一列（ SelectedRow ）的值，该值在 DataKeyNames in GridView ，



 <   asp：GridView     ID   =  gvScripts    runat   =  server    AutoGenerateColumns   =  False    OnRowCommand   =  gvScripts_RowCommand    DataKeyNames   =  DL_RECID  >  
 
 <  列 >  
 <   asp：TemplateField     HeaderText   =     HeaderStyle-Horizo​​ntalAlign   =   center    HeaderStyle-Width   =  30px >  
 <   ItemStyle     CssClass   =  HRLineCDL    Wrap   =  true    Horizo​​ntalAlign   = 中心 >  <   / ItemStyle  > ;  
 <   ItemTemplate   >  
 <   asp：ImageButton     ID   =  btnIFullView   < span class =code-attribute> AlternateText   = 完整视图    runat   =  server    CommandName   =  IFullView  
   
                                           CommandArgument   =  <％＃（（GridViewRow）容器）.RowIndex％>    /  >  
 <   / ItemTemplate  >  
 
 <   / asp：TemplateField  >  
 <   /列 >

解决方案

In Gridview RowCommand,

protected void gvScripts_RowCommand(object sender, GridViewCommandEventArgs e)
{
    if (e.CommandName == "IFullView")
    {
        int index = 0;
        string lstrVal = "";

        if (e.CommandArgument != "")
        {
            index = Convert.ToInt32(e.CommandArgument);
            lstrVal = gvScripts.DataKeys[index].Value.ToString().Trim();
        }
    }
}

And in .aspx,

I have a column with ImageButton. So, when I click this button, I need to get the value of a column (of SelectedRow), which is given in DataKeyNames in GridView,

<asp:GridView ID="gvScripts" runat="server" AutoGenerateColumns="False" OnRowCommand="gvScripts_RowCommand" DataKeyNames="DL_RECID">

    <Columns>
        <asp:TemplateField HeaderText="" HeaderStyle-HorizontalAlign="center" HeaderStyle-Width="30px">
            <ItemStyle CssClass="HRLineCDL" Wrap="true" HorizontalAlign="Center"></ItemStyle>
            <ItemTemplate>
                <asp:ImageButton ID="btnIFullView" AlternateText="Full View" runat="server" CommandName="IFullView"

                    CommandArgument="<%# ((GridViewRow) Container).RowIndex %>" />
            </ItemTemplate>
    
        </asp:TemplateField>
    </Columns>
