Question

这里我使用代码隐藏动态绑定网格列，因为我的GetSocailAnalytics方法根据传递的参数返回动态列。使用数据表绑定网格列后，当我点击网格行时，我的grd_OnRowCommand事件未触发。网格成功绑定。任何人都可以帮我解决这个问题。我的代码还有......

<asp:GridView ID="grd" EnableViewState="true" AutoGenerateColumns="false" OnRowCommand="grd_RowCommand"
                    runat="server" OnRowDataBound="grd_RowDataBound">
                    <Columns>
                    </Columns>
                </asp:GridView>
private void GetData()
{
    try
    {
        int TotalRecords = 0;
        DataTable dt = ClsSocialManager.GetSocialAnalytics(Convert.ToInt32(hdnReferrerId.Value), Convert.ToInt32(hdnReferralId.Value), out TotalRecords, Convert.ToInt32(hdnPageIndex.Value));
        if (dt != null && dt.Rows.Count > 0)
        {
            BindTemplateFiled(dt);
            grd.Visible = true;

        }
        else
        {
            grd.Visible = false;
        }
        lblStatus.Text = TotalRecords.ToString() + " Record(s) found";
    }
    catch (Exception ex)
    {
        lblStatus.Text = "Some Error Occured " + ex.Message;
        lblStatus.CssClass = "ErrMsg";
    }
}

Answer 1

单击按钮时会引发RowCommand事件 GridView控件。

单击网格行

时不会触发

解决方案是使用CommandName ="Filter"

将按钮（LinkButton）列添加到gridview

单击行时OnRowCommand =“grd_RowCommand”事件未触发
